Let’s explore “Vitamin B12 — lab reference”

Everyone talks about MTHFR. But what if that is only one piece of the puzzle? MTHFR helps process folate, while MTR helps recycle homocysteine back into methionine with the help of vitamin B12. Two genes. Different roles. One interco

PURSER WELLNESSOVER-METHYLATION - Are Your B Vitamins Hurting You?A conversation with Dr. Purser

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.
