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.

Low Testosterone and Vitamin Deficiencies

Men, want to know the #1 secret to good sex as we age? Nutrition consiting of vitamins, minerals, and amino acids. This covers a lot of ground, but let’s shorten that distance. I see hundreds of men in my practice every year for Hypogonadism (medically low testosterone) with a serum total testosterone level below 400 ng/dl (very severe) creating severe fatigue. Hard to have sex, or even to consider performing, if you are exhausted! Assuming you have no trauma (pituitary, heart, testicles, or penis) and you are noticeably exhausted after sex, or too tired to get going, then it probably is your
