You eat something sweet.
Your energy shoots up.
Then suddenly you are exhausted, foggy, irritable, and reaching for something else to get you through the day.
That cycle deserves a closer look.

What if your homocysteine level is telling you more than you realize?
When kidney function declines, homocysteine levels often rise because the kidneys play an important role in its metabolism and clearance. In people with chronic kidney d
What if high blood pressure is not something you should simply learn to live with?
Hypertension is often called the silent threat because you can feel completely normal while your blood pressure is putting added strain on your heart and bl
Why do some people in the same family get destroyed by black mold… while others are completely fine?
Why do two kids develop autism while their siblings are completely normal?
Dr. Dan Purser explains the hidden genetic issue behind both: a homocysteine problem that disrupts the transsulfuration pathway — the pathway responsible for making ~90% of your glutathione.
Without enough glutathione, your body simply cannot clear toxins. Mold, heavy metals, environmental chemicals… they stay stuck. This is why some people get chronically ill and others don’t, even when living in the exact same house.
In this episode we cover:
How a genetic disruption in the transsulfuration pathway causes low glutathione
Why most “glutathione” products on Amazon do nothing
The only two patented forms that actually work
Real cases of black mold toxicity and autism improvement
Why checking genetics is more important than just checking a homocysteine level
This is root-cause medicine — not symptom chasing.

Purser Wellness Coach Justace explains why looking at genetics alongside nutritional testing may help you ask better questions and make more informed decisions about your health.
Because personalized wellness should not begin with guessing
What if fatty liver is not only about what you eat?
Most people hear fatty liver and immediately think diet, weight, and alcohol.
But your genetics and the way your body processes nutrients may also be part of a much bigger picture.

Are your B vitamins making you feel worse instead of better?
Methylated B vitamins can be incredibly helpful for energy, homocysteine metabolism, neurological health, and many essential processes. But the right nutrient can become the wron
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 if your genes have been providing clues about your health your entire life?
Most people spend years treating symptoms without ever asking why those symptoms exist in the first place.

🚨 Why do you keep craving sugar and crashing even when you’re trying to eat healthy?
If you have an MTHFR variant, it’s likely NOT just willpower — it’s a methylation & energy production issue at the cellular level.
In our latest video, we
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.
