Let’s explore “Vitamin B12”

VDR encodes the vitamin D receptor, which helps regulate gene activity in response to active vitamin D. A receptor variant does not by itself mean receptors are absent or that the blood vitamin D level is low.

VKORC1 encodes vitamin K epoxide reductase, part of the vitamin K recycling system used in activating clotting proteins. It is not simply a vitamin K receptor.

Follow Dr. Purser’s teaching on folate, B12, sulfur pathways and antioxidant support around homocysteine.

ALPL encodes tissue-nonspecific alkaline phosphatase, an enzyme important to bone and tooth mineralization and vitamin B6 metabolism. Persistently low alkaline phosphatase can deserve a different evaluation from a general nutrient deficiency.

GSTO2 encodes glutathione S-transferase omega 2, a redox enzyme with dehydroascorbate reductase activity that connects glutathione chemistry with vitamin C recycling. It is a separate gene from GSTO1.

Encodes cubilin, part of a receptor system involved in uptake of the intrinsic-factor–B12 complex.

PURSER WELLNESSCope with Homocysteine Like a Pro!A conversation with Dr. Purser

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
