OVER-METHYLATION - Are Your B Vitamins Hurting You?

Some search terms matched

Can the B vitamins you are taking to support energy and methylation eventually make you feel worse? In this video, Jackson Larkin explains what practitioners often call “overmethylation,” a possible adverse response to supplemental methyl donors such as: • 5-MTHF or methylfolate • Methylcobalamin • Trimethylglycine, also called TMG • Multiple overlapping methylation formulas Possible warning signs can include irritability, anxiety, restlessness, insomnia, brain fog, fatigue, and feeling “wired but tired.” These symptoms do not prove that you are overmethylated. They can have many possible causes. The timing of symptoms, your total supplement exposure, nutrient status, genetics, medications, and health history all need to be considered. In this video, we discuss: • Why methylation is essential • How methyl-donor supplements support the body • Why the right vitamin can become the wrong dose • Ingredients to look for on your supplement labels • Why some people may need lower doses or non-methylated forms • How genetics and intracellular nutrient testing can guide a more personalized plan At Purser Wellness, we believe in a Start Low, Go Slow approach. The goal is not to eliminate methylation. The goal is to provide the right form and amount of support for each individual.

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

Some search terms matched

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.

EBV and Fibromyalgia Related??

Some search terms matched

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.

PEMT and connection to choline and glutathione!

Some search terms matched

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.
