— A Guide by the World’s Leading Homocysteine Expert For more than four decades as a practicing physician, I have watched thousands of patients cycle through conventional autoimmune treatments that address symptoms but never touch the fire underneath. Rheumatoid arthritis flares, lupus rashes, multiple sclerosis relapses, Hashimoto’s thyroiditis, fibromyalgia pain—these are not random. They share a common, often overlooked biochemical pathway: MTHFR mutations leading to elevated homocysteine that supercharges autoimmune inflammation . This is not fringe theory. It is the clinical reality I hav
Every woman with PCOS I’ve ever tested has a homocysteine problem...
That’s what Dr. Dan Purser says — and it might explain why so many women with PCOS struggle with pain, inflammation, fatigue, and even kidney or blood pressure issues.

Could an overlooked lab marker be providing valuable insight into your health?
Understanding your homocysteine level may help you and your healthcare provider identify opportunities to support cardiovascular health, healthy methylation, an
What if one overlooked lab marker is telling you more about your health than you realize?
Most people have never heard of homocysteine.
Yet when homocysteine levels are elevated, it may signal that critical pathways involving methylation,
Hi, I’m Dr. Dan Purser. For too long, autism has been treated as a mystery with only symptom management. In this episode, I break down what I’ve seen consistently in practice: the real root cause behind many cases on the spectrum.
It starts with genetic variants (especially MTHFR and related SNPs) that break the transsulfuration pathway. When kids can’t efficiently convert homocysteine into glutathione, they lose their ability to detox heavy metals and environmental toxins. The result is chronic inflammation, oxidative stress, and developmental challenges.
The good news? Once we identify these biochemical and genetic imbalances through proper testing, we can intervene at the root with targeted support — restoring methylation, rebuilding glutathione function, and giving the body what it needs to heal.
This isn’t theory. It’s the Purser Method® in action.
If you’re a parent searching for real answers instead of just labels, this episode is for you. The root cause has been solved. Now let’s talk solutions.

Why do some people in the same family get destroyed by black mold… while others are completely fine?
Why do two kids develop autism while their siblings are completely normal?
Dr. Dan Purser explains the hidden genetic issue behind both: a homocysteine problem that disrupts the transsulfuration pathway — the pathway responsible for making ~90% of your glutathione.
Without enough glutathione, your body simply cannot clear toxins. Mold, heavy metals, environmental chemicals… they stay stuck. This is why some people get chronically ill and others don’t, even when living in the exact same house.
In this episode we cover:
How a genetic disruption in the transsulfuration pathway causes low glutathione
Why most “glutathione” products on Amazon do nothing
The only two patented forms that actually work
Real cases of black mold toxicity and autism improvement
Why checking genetics is more important than just checking a homocysteine level
This is root-cause medicine — not symptom chasing.
