Serum vs. Intracellular Micronutrient Status

Posted by SpectraCell Laboratories, Inc. on Mon, Jul 24, 2017 @ 01:49 PM

Knowing one’s vitamin status can be incredibly empowering when it comes to health. In truth, “vitamin status” is somewhat of a loaded phrase because vitamins, like other micronutrients, exist both outside the cell (extracellular) and inside the cell (intracellular). Vitamin status outside a cell may be considered “within range” or “adequate” by conventional terms (e.g. when measured by standard lab testing), while vitamin status inside the cell – where metabolism actually occurs - may be depleted. Since vitamins function inside cells, extracellular measurements (such as serum testing) can be potentially misleading. Intracellular micronutrient levels, as opposed to what is present outside of cells (where it is not physiologically useful), is more clinically significant.

It is clear that serum micronutrient testing can yield important information. One obvious example is serum vitamin B12; when a person’s level is low, this can manifest as fatigue or anemia. Often, however, serum B12 may appear to be “normal,” but clinical symptoms of fatigue or B12 deficiency still exist. Why? Because serum B12 is a reflection of extracellular B12, whereas the intracellular reserve of B12 is what’s important; it matters little how much of a nutrient is present in one’s blood – if it is not getting into the cell, it won’t improve cellular or overall health. Consider this analogy: imagine being totally dehydrated, overwhelmed with thirst. If you jumped into a pool but could not drink the water, you remain thirsty because the water doesn’t make it into your body. Cells will be similarly starved if B12 doesn’t get assimilated.

So why has intracellular testing not replaced the serum variety? One simple reason is that serum testing has been used for so long that reference ranges are well established and understood, albeit potentially misleading. Another reason is that intracellular testing is more technologically advanced and fewer labs offer it. Finally, serum testing has been useful for detecting serious nutrient deficiencies that have progressed into obvious symptoms. But it is worth noting that intracellular testing helps detect deficiencies long before overt (and sometimes debilitating) symptoms occur –serum levels often fall in the “normal” range when a true intracellular deficiency exists.

The Role of Micronutrient Deficiencies in Attention Deficit Hyperactivity Disorder

Posted by SpectraCell Laboratories, Inc. on Fri, May 05, 2017 @ 11:27 AM

ADHD.jpgAttention Deficit Hyperactivity Disorder (ADHD) has become an increasingly prevalent condition, afflicting children, adolescents, and adults. Some hallmarks of this brain disorder include an inability to focus and/ or a failure to see projects/ activities to completion. Unbeknownst to most, ADHD can be exacerbated by micronutrient deficiencies. Evidence of the relationship between micronutrient status and ADHD-associated behaviors is compelling; the list below represents some examples of the micronutrient status-ADHD connection: 

Vitamin B6: Evidence suggests that high-dose supplementation of B6 is as effective as Ritalin for ADHD, probably due to its role in raising serotonin levels.

Folate (AKA Vitamin B9): Low maternal folate status during pregnancy has been linked to hyperactivity in children. Persons with the MTHFR (methyl tetrahydrafolate reductase) polymorphism are predisposed to folate deficiency, and are more likely to have ADHD.

Magnesium: A deficiency in this micronutrient is linked to poor functioning of the neurotransmitters that control emotion, social reactions, hyperactivity, and attention. Magnesium has a synergistic effect with vitamin B6.

Zinc: This nutrient is a cofactor required for the synthesis of dopamine, which impacts mood and concentration. Low zinc depresses both melatonin and serotonin production; this affects behavior and one’s ability to process information.

Carnitine: Reduces hyperactivity and improves social behavior in people with ADHD via its role in fatty acid metabolism. Some consider carnitine a safe alternative to stimulant drugs.

Serine: Administration of phosphatidylserine in conjunction with omega-3 fatty acids improved ADHD symptoms (attention scores) significantly more than omega-3 fatty acids alone, suggesting a synergistic effect. Phosphatidylserine increases dopamine levels.

Glutamine: A precursor to GABA (gamma-aminobutyric acid), the calming neurotransmitter that affects mood, focus, and hyperactivity. Disruption of glutamine-containing neurotransmission systems may cause ADHD. 

Choline: A precursor to acetylcholine, the neurotransmitter that regulates memory, focus, and muscle control (hyperactivity). 

Antioxidant status: Oxidative imbalance is prevalent in ADHD patients and likely plays a causative role. Glutathione, a very potent antioxidant, is commonly deficient in ADHD.
