Begin with the whole picture
Diet, absorption, medicines, illness and life stage can all affect nutrient status. Fatigue, cramps or brain fog can have many causes.
What testing can add
Ask which question a test answers and how well it has been validated. A result outside a range is one part of the assessment. Different tests and laboratories are not always interchangeable.
Choose a next step
Review food intake first, then discuss whether a supplement is needed, which form is appropriate and what follow-up would show benefit.
Product and testing details from our practice and shop. Discuss what fits your needs with your clinician. Current labels, availability and pricing are shown on the linked pages.

If you’ve had our Cellular Micronutrient Assay (CMA) with Redox testing, chances are you’ve looked at those two pages of results and thought, “Okay... now what does all this actually mean?” You’re not alone. This is one of the questions I hear most often from patients.
Let me walk you through exactly what each page shows, how the test works, and why these results are so powerful for creating a truly personalized plan to help you feel your best.
🔬 What is VARS? Why the VARS Trio (Glutathione + SOD + Catalase) is a game-changer for inflammation, recovery & fibromyalgia.
Jackson Larkin sits down with Lois Schweiger to break down Dr. Dan Purser MD’s VARS line — Validated, Absorbable, Reduced, and Stable antioxidants. Learn the science behind VARS Glutathione, VARS SOD (from deep-sea algae near volcanic vents), and the newest VARS Catalase (Nrf2 activator from seaweed).
Discover:
• How the VARS Triad works together in the mitochondria to fight oxidative stress and cytokines
• Why Catalase dramatically improved post-workout recovery (especially leg day!)
• Genetics, homocysteine, PEMT, and why many with fibro benefit from this protocol
• The importance of CMA (intracellular) testing and when to retest
• Real patient results, including severe inflammation cases
Perfect for anyone dealing with chronic pain, inflammation, slow recovery, or looking for root-cause support.
**June Anniversary Special**: $100 off Genetic + CMA testing — one order will be fully reimbursed!
