PURSER WELLNESSWhat is Intracellular Testing?A conversation with Dr. Purser

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

PURSER WELLNESSHomocysteine is the Secret AssasinA conversation with Dr. Purser

Homocysteine is nasty — but here’s the truth no one tells you. It doesn’t kill you directly — it triggers white blood cells to release IL-8 and MCP-1, causing inflammation, kidney failure, heart attacks, and strokes. Most doctors don’t even check it anymore, thinking there’s no fix. But there is. Whether from 17 genetic SNPs or 12 vitamin deficiencies (like B6 or B12), you can address it by supporting your body’s ability to convert homocysteine into glutathione.

PURSER WELLNESSWhat is a CMA with Redox Test and Why Do YOU Need It?A conversation with Dr. Purser

CMA testing shows what nutrients are inside your cells, not just floating in your blood, giving a true picture of deficiencies. When combined with Redox, it also tracks inflammation markers and oxidative stress—giving a full view of your health and guiding precise supplementation.

PURSER WELLNESSThe Hidden Molecule Driving Inflammation: Understanding the Purser Model of HomocysteineFrom the reading room

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

ESR1 encodes estrogen receptor alpha, which helps cells respond to estrogen. Receptor signaling is different from the amount of estrogen measured in blood.

FOLR1 encodes folate receptor alpha, which helps cells take up folate and has an important role in folate transport at the brain’s barriers. Blood folate and folate availability in the nervous system are not identical measurements.

FOLR2 encodes folate receptor beta, a folate-binding protein expressed in particular cell types, including subsets of immune cells. It is distinct from the FOLR1 receptor and the SLC19A1 reduced folate carrier.
