Homocysteine is the Secret Assasin

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.

Autism Answered - Root Cause Solved with #1 Reviewed MD in the USA

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.
