Vitamin K May Boost Performance in Athletes

cyclist-1.jpegVitamin K is often regarded as a nutrient for improving heart health, lowering cancer risk, and increasing bone density, but it also appears to improve fitness even in healthy athletes. Like most nutrients, it seems to have quite versatile roles.

In this small study, 26 trained male and female athletes were administered placebo or vitamin K2 supplements for eight weeks while they maintained their regular exercise routines. At the beginning of the study and after eight weeks, each person completed a fitness test on an exercise machine designed to quantify their physical work load, oxygen consumption, respiratory rate, cardiac output, and heart rate.  

Vitamin K2 supplementation was associated with a 12% increase in cardiac output (volume of blood that the heart is capable of pumping per beat). The authors suggest that vitamin K2, which has previously been shown to play a role in energy metabolism (especially in tissues with high energy requirements such as skeletal muscle and heart) might be considered in healthy athletes to improve performance.

Vital to Victory: Micronutrient Requirements for Athletes

Posted by SpectraCell Laboratories, Inc. on Wed, Jun 21, 2017 @ 01:25 PM

From a nutritional standpoint, the athlete’s focus should include both macronutrients – protein for muscle rebuilding, carbohydrates for energy renewal, fats for nerve function – as well as the critically important micronutrients – which are the vitamins, minerals, antioxidants and amino acids your body needs to function optimally every day and over a lifetime.

Hear Dr. Grabowski’s take on the role of micronutrients in sports nutrition.

Above all, we are all biochemically unique, and several factors affect our personal micronutrient needs - age, lifestyle, intensity of physical training, prescription drug usage, past and present illness or injuries, absorption rate, genetics and more. The “normal” amount of each micronutrient varies from athlete to athlete, and even in the same athlete depending on circumstances in his or her life.

SpectraCell’s Micronutrient test measures 33 vitamins and minerals in your body, but goes even further – it measures functional, long-term levels within the cell, which means SpectraCell’s micronutrient test not only identifies deficiencies but is also a valuable tool in predicting health concerns before overt symptoms occur. How's that for a test?!
