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.

MTHFR & The Never-Ending Sugar Crash Cycle: Why You’re Always Tired & Craving Sweets
If you have an MTHFR variant (C677T or A1298C), you may constantly battle fatigue, sugar cravings, and energy crashes — even when you’re “doing everything right.”
In this video, we break down exactly why this happens:
How MTHFR/methylation issues impair ATP (energy) production at the cellular level
Why your body desperately reaches for quick glucose
The vicious cycle of blood sugar spikes → insulin crashes → more cravings & fat storage
The downstream effects on antioxidants, DNA repair, and overall energy
How to finally break the cycle:
Targeted supplementation that fills methylation “holes” (what we learned from 15–20k intracellular tests)
Why our MTHFR Daily multivitamin was specifically formulated for this
The power of CMA intracellular testing
Intermittent fasting (12–16 hrs)
Fasted cardio (even just a brisk walk)
High-protein, real-food diet with minimal processed sugars
If you’re tired of the sugar rollercoaster and want stable energy, this is for you.

🔬 What is VARS? Why the VARS Trio (Glutathione + SOD + Catalase) is a game-changer for inflammation, recovery & fibromyalgia.
Jackson Larkin sits down with Lois Schweiger to break down Dr. Dan Purser MD’s VARS line — Validated, Absorbable, Reduced, and Stable antioxidants. Learn the science behind VARS Glutathione, VARS SOD (from deep-sea algae near volcanic vents), and the newest VARS Catalase (Nrf2 activator from seaweed).
Discover:
• How the VARS Triad works together in the mitochondria to fight oxidative stress and cytokines
• Why Catalase dramatically improved post-workout recovery (especially leg day!)
• Genetics, homocysteine, PEMT, and why many with fibro benefit from this protocol
• The importance of CMA (intracellular) testing and when to retest
• Real patient results, including severe inflammation cases
Perfect for anyone dealing with chronic pain, inflammation, slow recovery, or looking for root-cause support.
**June Anniversary Special**: $100 off Genetic + CMA testing — one order will be fully reimbursed!

Dan Purser MD interviews a patient with a brutal sarcoidosis case involving sky-high SIL2R cytokines, GI sarcoid, heart damage, and years of being dismissed by doctors. After spleen removal, repeated ER visits, and nitroglycerin dependence, he finally found answers.
Learn how cytokine testing and the VARS Trio (Glutathione + SOD + Catalase) led to rapid improvement — going from bedridden fear to playing with grandkids in just weeks.
This episode highlights the power of root-cause medicine for complex inflammatory conditions and offers hope for those who feel lost in the system.
Perfect for listeners dealing with sarcoidosis, chronic inflammation, autoimmune issues, or cytokine-related symptoms.

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.
The Overlooked Link Between MTHFR Mutations, Hyperhomocysteinemia, PCOS, Fibromyalgia, Chronic Inflammation, and Renal Decline — and Why Precision Genetic Testing May Be the Missing Step

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.
