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
Searchable captionsMTHFR 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.
Searchable captionsIntracellular 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
Searchable captionsHigh 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
Searchable captionsDr. Purser explains how certain environmental chemicals can trigger major inflammatory events in infants and young children—events that may contribute to autism in some cases.
Searchable captionsYour body’s ability to detox depends on one critical pathway—turning homocysteine into glutathione. But for millions with MTHFR or other genetic SNPs, this process is broken, leaving them vulnerable to toxins, inflammation, and cytokine storms. That’s why VARS Glutathione is such a breakthrough: it’s reduced, functional, and proven to lower harmful cytokines like IL-8 and MCP-1, giving your body the detox power it needs. After 15 years of research and real patient results, it’s the only oral glutathione that actually works where it matters—inside your cells.
Searchable captionsWhat 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.
Searchable captionsGenetic SNPs are tiny changes in your DNA that can drastically affect how well your enzymes and proteins work. For example, being homozygous for MTHFR C677T leaves that enzyme functioning at only about 30% efficiency, which can drain your energy and impair folate processing. Similarly, errors in SOD genes reduce your body’s ability to neutralize free radicals. While we can’t change your genes, we can work around them by identifying these weaknesses and filling the gaps with targeted nutrition and supplementation—helping your body function closer to its full potential.
