GENOVA™ Neopterin Biopterin Urine Profile for MTHFR

In the title

This test result is bad and could indicate an infection, especially viral. This is a great test for those with A1298C and especially who are Homozygous A1298C. Neopterin is bad while biopterin is good. If neopterin is repeatedly high, the BH4 is low. Neopterin is a sensitive marker of cellular mediated immunity. Reduced levels reflect cellular immunity weakening. Increased neopterin occur with infectious, inflammatory, immune system dysfunction or neoplastic disease evolution. Excessive neopterin negatively impacts the Nitric Oxide pathway in the body (e.g. excessive peroxynitrite formation an

Glutathione and Your Ability To Detox?

In the description

Your body’s ability to detox depends on one critical pathway—turning homocysteine into glutathione. But for millions with MTHFR or other genetic SNPs, this process is broken, leaving them vulnerable to toxins, inflammation, and cytokine storms. That’s why VARS Glutathione is such a breakthrough: it’s reduced, functional, and proven to lower harmful cytokines like IL-8 and MCP-1, giving your body the detox power it needs. After 15 years of research and real patient results, it’s the only oral glutathione that actually works where it matters—inside your cells.

DHFR

In the description

DHFR helps reduce folic acid and dihydrofolate to tetrahydrofolate-related forms used in cellular metabolism. This is one part of the folate system, distinct from MTHFR and folate transport into cells.

MTHFS

In the description

MTHFS encodes an enzyme that converts 5-formyltetrahydrofolate into 5,10-methenyltetrahydrofolate. This places it in folate interconversion; it is not another name for MTHFR or a direct maker of methylfolate.

OVER-METHYLATION - Are Your B Vitamins Hurting You?

In the description

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.

🚨 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
