Let’s explore “ARFID: food variety, nutrient gaps, and testing questions”

A post from Purser Wellness on Substack, covering testing and nutrients.

PURSER WELLNESSDo you need to STOP vitamins before Intracellular Testing?A conversation with Dr. Purser

Patients often ask if they should stop supplements before an intracellular CMA test, and the answer is no. The test measures nutrient status inside your cells over the last 90–100 days, so stopping vitamins right before won’t change the results. At most, you might skip your dose a few hours before the draw, but it’s not necessary—CMA still provides an accurate snapshot of your nutrient levels while you’re on your current routine.

PURSER WELLNESSWhat Is Genetic Testing?A conversation with Dr. Purser

Genetic testing has only been around for about 20 years, since the Human Genome Project made it possible to identify thousands of SNPs (gene variations) linked to disease and health issues. While gene editing with tools like CRISPR may be a future reality, for now the best way to “work around” your genes is by supplementing with the right vitamins, minerals, and amino acids. That’s exactly what the DRP Genetics test does—focusing on SNPs like MTHFR, PEMT, and others tied to homocysteine, gut, and brain health—so you can take preventative steps against even serious conditions like dementia and Alzheimer’s.

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.

PURSER WELLNESSMTHFR & The Never-Ending Sugar Crash Cycle: Why You’re Always Tired & Craving SweetsA conversation with Dr. Purser

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.
