Dr. Purser shares his clinical perspective on homocysteine, methylation, and inflammatory patterns.
Continue on SubstackMAKE SENSE OF YOUR COPPER RESULTS
Use your zinc, total copper, and ceruloplasmin blood results to estimate NCC and the copper:zinc ratio.
This uses the formula in Dr. Purser’s handout: NCC (µg/dL) = total copper (µg/dL) − 3 × ceruloplasmin (mg/dL). NCC percentage = NCC ÷ total copper × 100. Copper:zinc ratio = total copper ÷ zinc, using the same units.
Calculated NCC is an estimate. Test methods and how much copper is bound to ceruloplasmin can affect it. It differs from a direct lab measurement of labile or exchangeable copper. It cannot diagnose fibromyalgia or copper toxicity, or choose treatment for you. Read about the limits of calculated NCC at Mayo Clinic Laboratories ↗

Also in Homocysteine: follow the connections
Most people have never heard of homocysteine , yet this small molecule may hold the key to understanding inflammation, cardiovascular disease, neurological problems, and many chronic conditions. For decades, homocysteine was viewed as a toxic substance in the blood. Doctors were taught that lowering it with B-vitamins might reduce heart disease risk. But research results were inconsistent, leaving many physicians unsure whether homocysteine truly mattered. New research and clinical observations are changing that view. We introduce a new framework called the Purser Model , which explains why ho
Also in Homocysteine: follow the connections
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

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
