Intracellular testing, or the CMA Cellular Micronutrient Assay, measures over 100 vitamins, minerals, amino acids, and antioxidants inside your cells—not just in your blood. Unlike serum tests, which show short-term levels, intracellular testing reveals what your cells have been missing over the last 100 days. Low levels can mean weak enzymes, non-functioning proteins, and accelerated aging. By identifying deficiencies and matching them with the correct nutrient forms for your genetics, you can target fatigue, anxiety, depression, and other chronic issues at the root.

That’s what makes VARS Glutathione different—it stays in its reduced, functional form all the way until your cells use it, giving you a real therapeutic dose that actually works.
Scurvy, no one should have it in these modern ages, but I see these patients again and again. Thiamine Deficiency is another that NO ONE knows to look at, but it’s there. Remember, these are INTRACELLULAR deficiencies, not just blood serum levels. You have to Dig Deep to get the root of the issue.
