Can bad genetics cause vitamin deficiencies?

High homocysteine signals a broken transsulfuration pathway, leaving you unable to detox or convert it into glutathione. This shows up in conditions like PCOS and fibromyalgia, where patients often struggle with inflammation, pain, and even infertility. Genetics play a big role—there are 17 SNPs that can lock homocysteine in place—but vitamin deficiencies can make it worse. The real breakthrough isn’t lowering homocysteine itself but calming the cytokines it triggers, like IL-8 and MCP-1. That’s why VARS Glutathione, the only patented oral form proven to work, is so powerful—it lowers those cy

MTHFR is one of the most studied genetic SNPs, with the two main variants being C677T and A1298C. These changes reduce the body’s ability to process folate and make energy, leaving people exhausted and deficient in key nutrients. Specialized folates, B12 forms, and glutathione can bypass the blockages, and products like MTHFR Daily were designed specifically to fill these nutrient gaps so patients can restore energy and thrive.

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. Get your CMA by calling o

High homocysteine often shows up first as widespread inflammation—pain all over, poor circulation, or even early warning signs of cardiovascular problems like stroke and heart attack. The best way to know for sure is through testing: a blood test can measure homocysteine directly, while a CMA with Redox uncovers the vitamin deficiencies driving it. For genetic causes, the DRP Genetics panel screens 15–16 of the 17 known SNPs that can cause permanently high homocysteine. If your levels are fixed by genetics, reduced glutathione and targeted B vitamins (like MTHFR Daily) are key to balancing the

What I see again and again is an inability to detox caused by failures in the Transsulfuration Pathway. This is your pathway that converts homocysteine to glutathione. If you have MTHFR or 16 other Gene SNPs, you will have problems with this pathway.

Not all genetic tests are created equal. Many only scratch the surface, while the best panels look at hundreds of SNPs that impact methylation, detox, hormones, and nutrient absorption. For real results, you need a test that’s private, comprehensive, and clinically useful—like the ones we recommend in practice that help guide targeted treatment plans.

Your genetic results might list “wild type,” “heterozygous,” or “homozygous,” but what does that mean? Wild type means both copies of your gene are normal, heterozygous means one is normal and one has a change, and homozygous means both copies have the same change. With genes like MTHFR, these variations can affect how efficiently your body processes nutrients like folate—sometimes cutting function by 40–70%—which is why targeted nutrition and testing matter.

Most glutathione supplements fail because they break down before your body can use them. VARS Glutathione is different—it’s patented, validated, and proven to raise real intracellular glutathione levels. That means it actually works to calm inflammation, lower cytokines, and protect your cells where it matters most.

The new DRP Genetics test, designed by Dr. Purser in collaboration with MaxGen, makes genetic testing simple and precise. Each kit comes pre-filled with everything you need—just swab your cheek, place it in the vial, and send it back the same day using the prepaid mailer. This curated panel focuses on key SNPs Dr. Purser selected after years of research, giving patients clearer answers and actionable insights into their health.

Superoxide dismutase (SOD)—your body’s first line of defense against DNA-damaging free radicals. SOD neutralizes superoxide radicals at the source of cellular energy production. But as we age—or if we have genetic SNPs—our ability to make SOD drops. That’s why we created VARS SOD, with over 10,000 IU per dose (most products have less than 240 IU). It’s a game changer for anti-aging, DNA protection, and reducing inflammation at the root.

Just because you have EBV antibodies doesn’t mean it’s active—it usually means you’ve built immunity. The real issue? Most fibromyalgia patients have low reduced glutathione, which viruses like EBV intentionally suppress. That’s why symptoms overlap: fatigue, pain, immune dysfunction. Fix the glutathione issue, and you can support recovery on a deeper level.
