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.

What if too much copper — not too little — is the reason your body feels out of balance? For some people, excess copper may be linked to fatigue, mood changes, hormone issues, brain fog, and unexplained health struggles that never seem to

They told you your symptoms were ‘normal.’ I designed a 22-SNP test to prove they’re not. Your fatigue, anxiety, inflammation, brain fog, weight struggles, and burnout may not be random. They may be written into your genetics. Most peo

Did you know testosterone is just as important for women as it is for men—especially during menopause? Low testosterone can lead to fatigue, low mood, and even a loss of motivation. If you’re struggling with these symptoms, it might be time

Follow Dr. Purser! Are you struggling with unexplained fatigue, muscle pain, or brain fog? High copper levels could be the hidden culprit—and fibromyalgia could be the diagnosis.

Just because you have EBV antibodies doesn’t mean it’s active—it usually means you’ve built immunity. The real issue? Most fibromyalgia patients have low reduced glutathione, which viruses like EBV intentionally suppress. That’s why symptoms overlap: fatigue, pain, immune dysfunction. Fix the glutathione issue, and you can support recovery on a deeper level.

One of the most powerful nutrients you’ve never heard of? Phosphatidylcholine. It builds the walls of your cells, protects your gut lining, supports nerve function, and even helps your body make bile. If you have a PEMT gene mutation, your body struggles to make it—and that means gut issues, nerve dysfunction, and chronic inflammation.

Did you know scurvy is still around today? It might sound like an old pirate disease, but a lack of Vitamin C can still cause fatigue, joint pain, bleeding gums, and slow healing. Without Vitamin C, your body can’t make collagen, which is essential for healthy skin, blood vessels, and connective tissues.

Superoxide Dismutase 3 (SOD 3), also known as extracellular SOD or ubiquitous SOD, plays a critical role in your body’s defense against inflammation and oxidative stress. Here’s why it matters: Stabilizes Mast Cells SOD 3 helps suppress mast cell activation, reducing the release of inflammatory mediators that contribute to conditions like skin inflammation, inflammatory bowel disease, and chronic pain. Reduces Pro-Inflammatory Cytokines By inhibiting cytokines like TNF-Alpha, SOD 3 can help soothe inflammation at its source. Supports Healthy Joints and Blood Vessels Whether you have joint disc

High homocysteine levels can lead to inflammation, joint and muscle pain, and even shifting pain throughout the body. It’s also linked to birth defects and chronic kidney failure, and can raise blood pressure. Six genetic SNPs (like MTR, MTRR, and CBS) and MTHFR mutations (like C677T) can prevent homocysteine from converting into glutathione, which is essential for keeping inflammation in check. Plus, 12 vitamin deficiencies may temporarily raise homocysteine levels, so addressing these deficiencies is key.
