Intracellular testing, or the CMA Cellular Micronutrient Assay, measures over 100 vitamins, minerals, amino acids, and antioxidants inside your cells—not just in your blood. Unlike serum tests, which show short-term levels, intracellular testing reveals what your cells have been missing over the last 100 days. Low levels can mean weak enzymes, non-functioning proteins, and accelerated aging. By identifying deficiencies and matching them with the correct nutrient forms for your genetics, you can target fatigue, anxiety, depression, and other chronic issues at the root. Get your CMA by calling o
If you’ve been struggling with severe chronic fatigue, unexplained anxiety, or cardiovascular red flags, your genes might be trying to tell you something. Millions of patients walk out of traditional clinics with normal blood tests, only to be told their crippling symptoms are "all in their head." If you carry the C677T variant, you aren't crazy—you are dealing with a breakdown in cellular biochemistry. The Problem With Synthetic Folic Acid The standard advice from standard doctors is to take synthetic folic acid. For someone with the C677T genetic mutation, this is disastrous. Your enzyme pat
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.

Feeling tired all the time is often dismissed as stress, aging, or a busy schedule.
But persistent fatigue can have many possible causes, including nutritional issues that may not be obvious from routine testing.

What if your recovery routine is just as important as your workout?
Sore muscles, lingering fatigue, and slow recovery can make it harder to stay consistent in the gym.
But what if supporting your body's recovery could help you get back
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.
