OVER-METHYLATION - Are Your B Vitamins Hurting You?

In the description

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.

What is MTHFR? What can YOU do about it?

In the description

MTHFR is one of the most studied genetic SNPs, with the two main variants being C677T and A1298C. These changes reduce the body’s ability to process folate and make energy, leaving people exhausted and deficient in key nutrients. Specialized folates, B12 forms, and glutathione can bypass the blockages, and products like MTHFR Daily were designed specifically to fill these nutrient gaps so patients can restore energy and thrive.

Homocysteine is the Secret Assasin

In the description

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.
