The Importance of Nutrition on Weight Loss

Posted by SpectraCell Laboratories, Inc. on Mon, Jun 04, 2012 @ 11:57 AM

Micronutrient TestingBelow is a list of various nutrients that affect a person's ability to gain or lose weight.

  • Zinc - reduces leptin, a beneficial hormone that regulates appetite, which is reversed by zinc repletion.
  • Asparagine - this amino acid increases insulin sensitivity which helps the body store energy in muscle instead of storing it as body fat.
  • Biotin - boosts metabolism by improving glycemic control (stabilizes blood sugar) and lowering insulin, a hormone that promotes fat formation.
  • Carnitine - carries fatty acids into cell so they can be burned for fuel; Helps reduce visceral adiposity (belly fat).
  • Calcium - inhibits the formation of fat cells; Also helps oxidize (burn) fat cells.
  • Lipoic Acid - improves glucose uptake into cells, which helps a person burn carbohydrates more efficiently.
  • Chromium - makes the body more sensitive to insulin, helping to reduce body fat and increase lean muscle.
  • Vitamin B5 - taking B5 lowers body weight by activating lipoprotein lipase, an enzyme that burns fat cells. One study linked B5 supplementation to less hunger when dieting.
  • Magnesium - low magnesium in cells impairs a person’s ability to use glucose for fuel, instead storing it as fat; Correcting a magnesium deficiency stimulates metabolism by increasing insulin sensitivity. Magnesium may also inhibit fat absorption.
  • Glutamine - reduces fat mass by improving glucose uptake into muscle.
  • Cysteine - supplementation with this antioxidant reduced body fat in obese patients.
  • Inositol - supplementation may increase adiponectin levels.
  • Vitamin B3 (niacin) - treatment with B3 increases adiponectin, a weight-loss hormone secreted by fat cells; Niacin-bound chromium supplements helped reduced body weight in clinical trials.
  • Vitamin A - enhances expression of genes that reduce a person’s tendency to store food as fat; Reduces the size of fat cells.
  • Vitamin E - inhibits pre-fat cells from changing into mature fat cells, thus reducing body fat.
  • Vitamin D - deficiency strongly linked to poor metabolism of carbohydrates; Genes that are regulated by vitamin D may alter the way fat cells form in some people.
  • Vitamin K - poor vitamin K status linked to excess fat tissue; Vitamin K helps metabolize sugars.

Nutritional Considerations of Diabetes

Posted by SpectraCell Laboratories, Inc. on Mon, Feb 06, 2012 @ 11:57 AM

DiabetesUNDERSTANDING DIABETES

According to the American Diabetes Association, type 2 diabetes is the most common form of diabetes. With this type of diabetes, cells do not receive enough insulin. As a result, cells starve for energy, and, over time, a glucose buildup in the blood stream causes negative effects on a person’s eyes, kidneys, nerves and/or heart.

Today’s fast-paced society has led to quicker, higher carbohydrate alternatives as food sources. As a result, there is a greater threat of developing diabetes due to cells becoming insulin-resistant.

Micronutrients such as niacin, magnesium, calcium, zinc, carnitine, inositol, alpha-lipoic acid, as well as vitamins E, B6 and D all play an important role in the prevention and treatment of diabetes.

Though diabetes is a serious disease - with the right treatment - living a longer, healthier life can be made easier.

THE ROLE OF MICRONUTRIENTS IN DIABETIC HEALTH

NIACIN
Niacin (nicotinamide) may help to preserve residual B-cell function in individuals with type 1 or type 2 diabetes. This B-vitamin is believed to be one of the components of the glucose tolerance factor (GTF).

MAGNESIUM
This mineral is involved in more than 300 enzymatic functions in the body. Magnesium deficiency has been associated with insulin resistance, glucose intolerance, dyslipidemia and hypertension, which have all been associated with diabetes mellitus. Magnesium has been found to be one of the more common micronutrient deficiencies in diabetes.

VITAMIN E
Low levels of vitamin E are associated with increased incidences of diabetes. Research suggests that individuals with diabetes mellitus have decreased levels of antioxidants. Increased antioxidant requirements may be a result of increased free radical production during periods of hyperglycemia.

ALPHA-LIPOIC ACID (THIOCTIC ACID)
This antioxidant has been shown to regenerate other antioxidants such as glutathione, vitamin E and vitamin C. Alpha-lipoic acid has been shown to enhance glucose uptake in skeletal muscle tissue, thus improving glucose regulation in diabetic mellitus individuals. In addition, this antioxidant can be beneficial in the treatment of diabetic polyneuropathy.

VITAMIN D
Obesity is often associated with vitamin D deficiency and also with type 2 diabetes. Research indicates that diabetic individuals (both type 1 and type 2) have a higher risk for bone fracture. This vitamin deficiency has clearly been associated with lower bone density. Subjects with hypovitaminosis D are at higher risk of insulin resistance and metabolic syndrome.

CHROMIUM
This trace mineral is fundamental in proper insulin function and is believed to facilitate the attachment of insulin to the cell’s insulin receptors. A lack of chromium can lead to insulin resistance, which leads to elevated blood levels of insulin and glucose. Elevated levels of glucose in the blood can lead to diabetes and cardiovascular complications. Food processing
removes most of naturally occurring chromium. However, chromium can be supplemented or found in brewer’s yeast, nuts, meat, whole grains, green beans and broccoli.

HOMOCYSTEINE
Homocysteine elevation is a risk factor for overall mortality in type 2 diabetic individuals independent of other risk factors. Adequate levels of pyroxidine (vitamin B6), folate and vitamin B12 are required for normal homocysteine metabolism.

MicronutrientsINOSITOL
This nutrient is found in high concentrations in peripheral nerves. There is some evidence that inositol may be effective in the treatment of diabetic neuropathy.

VITAMIN B6
Research shows that a deficiency of vitamin B6 may result in abnormal glucose tolerance, degeneration of the pancreatic beta cells, reduced insulin response to glucose and reduced serum and pancreatic insulin levels. In addition, vitamin B6 deficiency has been associated with polyneuropathies.

CALCIUM
Studies have shown that individuals with a low intake of calcium have an increased risk of non-insulin dependant diabetes mellitus. Numerous studies have also revealed that diabetes may be associated with abnormal regulation of intracellular calcium.

ZINC
This mineral has been associated with over 200 enzymatic functions in the body. Increased fasting blood glucose levels have been associated with low zinc. Zinc has been shown to be important in the synthesis, storage and secretion of insulin. Increased urinary zinc excretion has also been associated with diabetic individuals.

CARNITINE
This amino acid in the form of acetyl-L-carnitine has been shown to benefit those individuals with diabetic polyneuropathy. One of the proposed mechanisms is that this amino acid may restore the depleted nerve myoinositol content and decrease free radical production.

Understanding Obesity and Nutrition

Posted by SpectraCell Laboratories, Inc. on Mon, Jan 30, 2012 @ 10:22 AM

Obesity and NutritionIn the past, obesity was understood in fairly simple terms: excess body weight resulting from eating too much and exercising too little. Obesity is now regarded as a chronic medical disease with serious health implications caused by a complex set of factors.

Micronutrients and Obesity:

Obesity is a complex, chronic disease involving multiple components. It is the second leading cause of preventable death in America, second only to cigarette smoking, and increase the risk of illness from over 30 medical conditions including diabetes, hypertension, cancer, infertility, arthritis and heart disease. Prescription medications and procedures used to treat many of
these conditions often induce micronutrient deficiencies as well.

Availability of NutrientsAvailability of Nutrients:

Obesity often reduces the availability of certain nutrients. In a recent study, over 50% of obese patients were evaluated for Vitamin D status and found to be deficient. Since fat cells have
their own nutritional requirements, fat cells will draw from nutritional reserves in much the same way other organs do in order to perform normal cellular functions. The combination of reduced availability and increased demand for nutrients caused by excess fat cells ultimately causes multiple deficiencies that need to be corrected.

Regulation of Hormones Linked to Obesity:

Niacin (Vitamin B3) treatment has been shown to increase hormone levels that regulate metabolism of glucose and fatty acids. Decreased levels are associated with obesity and heart disease. Vitamin B5 helps breaks down fat cells so they can be used up by the body.

Low Zinc status is also associated with obesity. This may be due, in part, to the relationship between Zinc and leptin, a hormone that regulates appetite. Zinc depletion reduces leptin levels, while Zinc repletion reverses this effect.

Obesity and NutritionFat Cell Formation:

Studies suggest that a form of Vitamin E (tocotrienol) inhibits pre-fat cells from changing into mature fat cells, resulting in a decrease in body fat. Calcium intake has also been associated with weight loss through its ability to inhibit the formation of fat cells. It also promotes the oxidation, or burning of fat cells, therefore reducing the risk of obesity.

The Effect of Amino Acids on Body Composition:

Carnitine is an important nutrient that helps muscle cells utilize energy and burn calories. Evidence shows that supplementation with carnitine when combined with an exercise program may induce positive changes in body composition by reducing (belly fat) more efficiently than without supplementation. Glutamine has been shown to reduce fat mass and improve glucose uptake in skeletal muscle and the relatively unknown amino acid Asparagine can improve insulin sensitivity by increasing the amount of sugar taken into muscle tissue to be burned for fuel.

Obesity and Insulin Resistance - Partners in Crime:

Obesity severely impairs the body’s ability to efficiently burn dietary carbohydrates. This is caused primarily by the body’s inability to use insulin, which is the hormone that helps the transport of sugars into muscles where they can be used for fuel instead of being stored as fat. Optimal micronutrient and mineral status are necessary for proper insulin function.

Vascular Health and ObesityVascular Health in Obesity:

Blood vessels in overweight individuals are typically not as pliable and healthy as normal weight people. Vitamin C supplementation has been demonstrated to improve vascular function in overweight people. Similarly, minerals such as Magnesium, Zinc, Calcium and Copper have all shown positive effects on blood pressure and vascular health. Overweight people tend to have high blood pressure, which is intensified by vitamin deficiencies. Since so many nutrients (Folate, Biotin, Carnitine, Vitamins A, C, and E and several minerals) are involved in the maintenance of healthy blood vessels of both normal weight and overweight people, a comprehensive evaluation of how they are performing in the cells of obese patients is crucial.

Oxidative Stress and Inflammation:

Numerous studies link oxidative stress and inflammation with  obesity. Visceral adiposity (belly fat) is particularly high in dangerous enzymes that cause oxidative stress. Weight loss certainly counteracts this phenomenon and studies show that the amount of weight lost directly correlates to decreases in oxidative stress. Belly fat also causes inflammation of the liver, which is particularly common in obese people. One recent study  demonstrated that Coenzyme Q10 decreased obesity-induced inflammation of the liver. Similarly, inflammation in blood vessels of obese patients contributes to heart disease and stroke, which can be alleviated in part through proper antioxidant supplementation. It is imperative that antioxidant status be optimized, especially in obese patients. SpectraCell’s micronutrient testing measures several specific antioxidants and gives an overall picture of how well all the antioxidants are working together.

Malabsorption Issues After Bariatric SurgeryMalabsorption Issues After Bariatric Surgery:

The impaired ability to absorb nutrients after bariatric procedures routinely causes multiple vitamin and mineral deficiencies in patients. Due to fat malabsorption after bariatric surgery, deficiencies in fat soluble Vitamins (A, D, E and K) are extremely common. Neurological complications such as confusion, impaired muscle coordination, even seizures may occur after bariatric procedures, due to a lack of B Vitamins, especially Thiamine. These complications can occur acutely or decades later. A comprehensive evaluation of nutritional status in bariatric patients is critical in maintaining post-op health.

SpectraCell Partners with Gluten Free Works

Posted by SpectraCell Laboratories, Inc. on Thu, Apr 21, 2011 @ 03:48 PM

Hand and HealthSpectraCell has recently partnered with Gluten Free Works who is “Helping people get well, look good and stay healthy living gluten free.” ™

Gluten Free Works® helps you understand your food, your diet and your digestion. They show you what causes health problems and how to treat them naturally. One of the tools that they suggest is nutritional testing.  They believe that the key to good health for those with gluten sensitivity and/or celiac disease is a gluten-free lifestyle.

What is Celiac Disease?

Celiac disease is characterized by the inability to tolerate gluten, which is a protein found in wheat, rye and barley. When gluten is ingested by a person with celiac disease, an allergic reaction follows that causes serious damage to the intestinal wall, ultimately creating malabsorption issues and a host of cascading health problems. Some estimate that celiac disease is prevalent in over 2% of the general population.

I take a Multi-Vitamin and Eat a Gluten Free Diet.  Isn’t that Enough?

Multi-VitaminThe simple answer is no. Just as every person is different, the “normal” amount of each micronutrient varies from person to person, and even in the same person depending on circumstances in his or her life.  We are all biochemically unique, and several factors affect personal micronutrient needs – age, lifestyle, metabolism, prescription drug usage, past and present illnesses, absorption rate, genetics and more.

Especially in the case of celiac disease, whether diagnosed or undiagnosed, comprehensive nutritional testing is super important.  Celiac patients are notoriously at higher risk for nutrient deficiencies, largely due to malabsorption issues.  But when it comes to supplements, the “more is better” philosophy is just plain wrong.  Balance is key. SpectraCell’s Micronutrient test is the answer.

SpectraCell’s Micronutrient Test measures 33 vitamins and minerals in your body.  But the SpectraCell test goes even further – it measures functional, long-term levels within the cell, which means SpectraCell’s Micronutrient Test evaluates how well your body actually utilizes each nutrient.  Your body may need more of a nutrient than someone else, or perhaps your body lacks the coenzymes needed to transport it, or perhaps it is not absorbed properly after ingestion.  That is why an individual assessment of your nutritional status is important.

True healing begins with your body’s foundation – micronutrients – the vitamins, minerals and antioxidants your body needs to function optimally every day and over a lifetime.

Predisposition to Nutritional Deficiencies

Researchers followed a group of celiac patients who were on a gluten-free diet for 10 years and they found that half of the adult celiac patients showed signs of poor vitamin status. Since production of digestive enzymes is generally less efficient in celiac patients, absorption of nutrients from food is compromised.  

Antioxidant Status of Celiac Patients

Intestinal inflammation, so commonly seen in celiac patients, creates oxidative stress and as a result, the antioxidant status of celiac patients is significantly reduced, mostly by a depletion of glutathione, considered by many the most potent antioxidant in our bodies. In addition, levels of other antioxidants such as cysteine and vitamin C will affect glutathione status.  You can see how measuring a single nutrient only gives a small piece of the metabolic puzzle.

Fortunately, SpectraCell’s micronutrient test also gives your SpectroxTM score, which is a measurement of your Total Antioxidant Function. In short, it measures how well your cells stand up to oxidative stress.  SpectraCell’s micronutrient test also measures the function of several powerful antioxidants such as lipoic acid, coenzyme Q10 and vitamin E.  Even a single deficiency can negatively affect your SpectroxTM score.  Since oxidative stress is an important factor in the pathogenesis of celiac disease, raising your SpectroxTM score is important.

A Special Role for Glutamine

One hallmark of celiac patients is that they tend to have damage in the lining of their small intestine.  This damage increases the permeability of the walls of their digestive tract, allowing normally benign substances into the bloodstream, where they are no longer treated as harmless.  An allergenic, or autoimmune, response follows wreaking havoc throughout the body. Glutamine is an amino acid that is particularly effective in mitigating this dangerous cascade of events starting in the gut. Deprivation of glutamine results in increased intestinal permeability since glutamine helps to form tight junctions between cells of the delicate intestinal wall.

NeurologyNeurological Problems Stem from Nutrient Deficiencies

Researchers estimate that 11-41% of celiac patients have vitamin B12 defiency, which impairs function of the nervous systems.  In fact, resolution of vitamin B12 deficiency will in many cases resolve neurological problems associated with celiac disease. Similarly, a deficiency in copper will often manifest as neurological problems or anemia in celiac patients.  In fact, some researchers suggest that celiac disease should be considered  in patients with copper deficiency, even if there are no gastrointestinal problems.

Folate Deficiency

Celiac patients are at higher risk of B vitamin deficiencies, specifically folate. There are several reasons for this. First, the primary transporter of folate into our bloodstream is found on the tips of the finger-like projections in the intestinal wall called villi. Since intestingal damage (called atrophy) is so common in celiac patients, the process of absorption of nutrients, and especially folate, is severely impaired. Second, the pH of the stomach affects folic acid absorption. The higher the pH, the lower the absorption of folic acid, which is the case in celiac patients. Third, many medications used in inflammatory conditions of the gastrointestinal tract are known to be folate depleting.

Bone Building Nutrients for Celiac Patients

Compromised bone health is often an unfortunate consequence of celiac disease largely because a much higher percentage of children with celiac are deficient in magnesium, calcium and vitamin D compared to children without celiac.  These nutrients work together in many ways.  For example, when there is sufficient vitamin D, 30-40% of intestinal calcium can be absorbed but in the presence of vitamin D deficiency, only 15% of calcium is absorbed, leading to poor bone health among other things. It is easy to see how correcting even a single nutrient deficiency can indirectly help the status of another.  

Depletion of Minerals

The impact of mineral deficiencies is extremely broad.  For example, zinc deficiency compromises the immune system and is implicated in many skin disorders, which often accompany celiac disease.  In a recent study on children with celiac disease, it was found that zinc  levels were up to 30% lower in children with untreated celiac, and that over 50% of patients with celiac have low zinc levels. Selenium deficiency is also common in celiac patients.  Since thyroid is particularly sensitive to selenium, a deficiency in this mineral, which also serves as a powerful antioxidant, can contribute thyroid dysfunction.

Fatigue in Celiac – Corrected with Supplementation

Fatigue is a very common symptom of celiac disease.  Although several nutrients contribute to energy production (such as B vitamins and chromium, for example), the relatively unknown amino acid carntine is intimately involved in energy production and particularly effective in reducing fatigue.  Interestingly, levels of carnitine are lower in celiac patients.  In fact, one study showed that fatigue was significantly reduced in a group of celiac patients when they were supplemented for six months with carnitine.

A Multi-Faceted Approach

Since so many nutrients are needed to keep our amazingly complex digestive, immune and other systems functioning properly, a comprehensive assessment of your nutritional status is key, especially indisorders like celiac disease where the risk of deficiency is particularly high.  The potential improvement of symptoms when even a single deficiency is corrected can often be quite dramatic.  

SpectraCell's micronutrient test evaluates how well your body absorbs and utilizes each of these nutrients.

The Role of Micronutrients in Heart Disease

Posted by SpectraCell Laboratories, Inc. on Fri, Feb 11, 2011 @ 01:56 PM

Is Your Heart at Risk?

 

 

There is compelling evidence that deficiencies in vitamins, minerals and antioxidants are a major contributor to cardiovascular disease and its symptoms. Similarly, the use of many drugs in treating heart disease often lead to various nutrient deficiencies.

Micronutrients and High Blood Pressure:

High blood pressure can result in physical damage to thMicronutrients and High Blood Pressuree walls of our blood vessels. Although the causes of hypertension often overlap, micronutrient deficiencies can cause or worsen this condition. Several mineral deficiencies such as zinc, copper, calcium and magnesium have been linked to high blood pressure.

Research also suggests that a high level of oxidative stress eventually takes its toll on our arteries, ultimately causing hypertension. Several studies of coenzyme Q10 lowered blood pressure significantly. The antioxidant vitamins C and E help blood vessels maintain their flexibility, allowing them to easily dilate and contract. The powerful antioxidant lipoic acid reduces blood pressure by inhibiting inflammatory responses in the blood vessels. Vitamin D deficiency is linked to hypertension because it contributes to endothelial dysfunction, a condition where the lining of blood vessels cannot relax properly and secrete substances that promote inflammation of the blood vessel lining.

Prevent Arterial "Scarring":

Vitamin B6, B12, folate, serine and choline are all necessary to properly metabolize homocysteine and reduce the risk of arterial scarring. In fact, B-vitamin therapy has been an effective treatment for reducing heart disease and blood pressure.

Keeping the Heart Muscle StrongKeeping the Heart Muscle Strong:

The heart’s requirement for energy compared to other muscle tissues is incredibly high. Carnitine is an amino acid that facilitates the transport of fatty acids into heart cell mitochondria, thus helping the heart meet its strong demand for chemical energy. It also helps muscles, including the heart, recover from damage, such as from a heart attack. Vitamin B1 (thiamine) is another key component in energy metabolism by helping the heart increase its pumping strength. Deficiencies of vitamin B1 have been found in patients with congestive heart failure, as long-term use of diuretic drugs, which are often prescribed to those patients, deplete the body’s storage of thiamine. Coenzyme Q10 is also required by cardiac tissue in large amounts to properly function. Statin drugs deplete the body of CoQ10, so deficiencies of CoQ10 in statin-users are particularly common.

Heart Disease is an Inflammatory Process:

Scientists now emphasize that heart disease is actually an inflammatory condition within the blood vessels. Inflammation and oxidative stress work together damaging arteries and impairing cardiac function. Several antioxidant nutrients minimize this inflammatory process.

Glutathione is the most potent intracellular antioxidant and actually helps to regenerate other antioxidants in the body. Cysteine, glutathione, B2, selenium, Vitamin E and Vitamin C work together to reduce oxidative stress throughout the entire cardiovascular system.

How Well Do Your Arteries Fight Oxidative Stress?:

An optimal antioxidant status is particularly important in the Preventing Atherosclerosisprevention of chronic diseases such as heart disease and stroke. Since many antioxidants work together synergistically, measuring a single antioxidant may not provide an accurate picture of total antioxidant function. SpectraCell’s SPECTROX™ score will provide a complete and accurate picture of the overall antioxidant status of patients.

Preventing Atherosclerosis:

One of the major culprits in heart attacks and stroke is the buildup of plaque within the arteries throughout the body. Lipoproteins become dangerous when they are oxidized, making them “sticky” and causing blockage of the arteries (atherosclerosis). Micronutrient deficiencies accelerate atherosclerosis. One study showed that oleic acid (found primarily in olive oil) reduces oxidative damage to lipoproteins. It also facilitates absorption of vitamin A in the gut, which is important because vitamin A is linked to lower levels of arterial plaque, primarily due to its antioxidant effect in protecting lipids from oxidation.

Vitamin K supplementation to deficient people slowed the progression of plaque formation in major arteries. Vitamin B3 (niacin) lowers blood cholesterol (fats in the blood), inhibits the oxidation of LDL, and is currently the most effective drug available for raising the heart-protective, good HDL cholesterol. One study on chemicals made from vitamin B5 (pantothenic acids) showed a decrease in blood triglycerides and cholesterol, and evidence suggests that vitamin E can even retard existing atherosclerosis. Another study showed that inositol, a member of the B vitamin family, decreases dangerous small, dense lipoproteins that easily penetrate blood vessel walls and cause atherosclerosis.

Preventing StrokePreventing Stroke:

A recent study on more than 20,000 people concluded that adequate vitamin C levels reduced risk of stroke by over 40%. Similar studies on calcium, magnesium, folate and biotin all concluded that adequate levels of these nutrients contribute to a reduction in the incidence of stroke.

Vitamin D Update from the Institute of Medicine

Posted by SpectraCell Laboratories, Inc. on Tue, Dec 28, 2010 @ 03:46 PM

Change in Dietary Reference Intake (DRI) for Vitamin D

new vitamin d reportIn November 2010, the Institute of Medicine (IOM) released a report setting new dietary intake levels for calcium and vitamin D. These recommendations are replacing the previous references (which were called Adequate Intake values) that were made in 1997. The IOM states that these new DRI values are based on higher quality studies than were previously available.

For vitamin D, the estimated average requirement for both males and females under 70 years old is 400 international units (IU). In order to achieve this requirement, the scientists have set the recommended dietary allowance a little higher at 600 IU per day. For seniors over 70, that DRI is still higher at 800 IU per day.

These recommendations are somewhat higher than the previous 1997 values, although there is considerable controversy over these recommendations. Many healthcare practitioners believe these recommendations are still too conservative. Challenging the Concept of “More is Better” the IOM states that toxicity concerns exist with mega-doses that are becoming more common in supplements. Vitamin D is fat-soluble so it will be stored in the body’s fat tissue and when extra is ingested it is not excreted via urine. Instead, it remains in the body even if it is not needed.

In a press release from the Institute of Medicine, they state that excessive vitamin D can damage the kidneys and heart, although the exact level of toxicity is not clear and likely differs among people. For this reason, the IOM states that the concept of “more is better” should be challenged when referring to nutrients.

SpectraCell agrees with the IOM on this issue that “more is not necessarily better.” In fact, micronutrient testing by SpectraCell reinforces this concept since it measures whether or not a deficiency exists. If a person shows vitamin D deficiency on the micronutrient test, supplementation will likely benefit the patient. If vitamin D functions well (in other words, the person is not vitamin D deficient), they should not take extra vitamin D supplements.

A Word About Vitamin D from the Sun

We can get vitamin D from food, supplements or the sun. The surface of the skin has special vitamin D receptors that allow us to manufacture vitamin D from sunlight, or more specifically ultraviolet (UVB) radiation. Unlike ingested vitamin D, excessive exposure to sunlight does not cause vitamin D toxicity because any excess vitamin D from the sun is immediately metabolized into harmless by products and removed from the body. In fact, depending on latitude, time of day, season and skin tone, 5-10 minutes of exposure to sunlight contains about 3000 IU. Supplements usually contain less than 1000 IU.2

Which Form is Best? D2 or D3

There are two major forms of the vitamin: D2 (ergocalciferol) and D3 (cholecalciferol). Some studies suggest that vitamin D2 is only about 30% as effective as D3 in maintaining tissue levels but a 2008 study showed that vitamin D2 is as effective as D3 in maintaining vitamin D concentrations in the body.3 Both D3 and D2 are metabolized in the liver and kidneys to form either the non-active storage form (25- hydroxyvitamin D) or the biologically active form (1,25-dihydroxyvitamin D). SpectraCell’s micronutrient test measures vitamin D3.
