THORNE Methyl-Guard Plus - Active Folate with B2, B6, B12 - Methylation Support - 30 Servings

Top Ingredients in Methyl-Guard Plus

Active Folate (L-5-MTHF): 1 mg (as calcium L-5-methyltetrahydrofolate) – the biologically active form that contributes to homocysteine metabolism and DNA synthesis.
Vitamin B12 (Methylcobalamin): 500 mcg – supports nerve health and red blood cell formation.
Vitamin B6 (Pyridoxal 5'-Phosphate): 20 mg – involved in amino acid metabolism and neurotransmitter production.
Vitamin B2 (Riboflavin 5'-Phosphate): 10 mg – essential for energy production and antioxidant function.
Betaine (Trimethylglycine): 500 mg – a methyl donor that supports the conversion of homocysteine to methionine.

What Is Methyl-Guard Plus?

THORNE Methyl-Guard Plus is a precisely formulated blend of active B vitamins and methyl donors designed to support optimal methylation processes in the body. Methylation is a fundamental biochemical pathway involved in DNA synthesis, neurotransmitter production, detoxification, and homocysteine regulation. This formula provides active folate as L-5-methyltetrahydrofolate (5-MTHF), along with vitamin B12 as methylcobalamin, vitamin B6 as pyridoxal 5'-phosphate, vitamin B2 as riboflavin 5'-phosphate, and betaine (trimethylglycine). Because these nutrients are supplied in their bio-available forms, the body can utilise them immediately – an excellent choice for those with genetic variations like MTHFR that can impair conversion of synthetic folic acid.

Key Benefits of Methylation Support

Healthy methylation supports numerous physiological functions. One of its most important roles is in maintaining already normal homocysteine levels. Elevated homocysteine is associated with cardiovascular and cognitive concerns. By providing the necessary cofactors, Methyl-Guard Plus contributes to the conversion of homocysteine to methionine, a process that relies on folate, B12, B6, and betaine. Furthermore, methylation is essential for neurotransmitter synthesis, including serotonin and dopamine, which may support mood and cognitive function. The B vitamins in this formula also contribute to normal energy-yielding metabolism and red blood cell formation.*

Who Can Benefit From Methylation Support?

Methyl-Guard Plus is suitable for anyone looking to support cardiovascular health, brain function, and overall methylation. It is particularly relevant for individuals with MTHFR gene variants, those with elevated homocysteine levels, vegetarians and vegans (who may have lower B12 intake), and people over 50 whose methylation efficiency may decline. Athletes and active individuals may also benefit from enhanced energy metabolism. However, it is always recommended to consult a health care professional before starting any new supplement regimen, especially if you have a medical condition or are taking medications.

How to Choose a Methylation Supplement

When selecting a methylation support supplement, the form of nutrients matters. Many products uses synthetic folic acid, which requires conversion to active folate – a process that can be inefficient. Methyl-Guard Plus uses active 5-MTHF, bypassing this conversion. Similarly, methylcobalamin is the active coenzyme form of B12, versus cyanocobalamin which must be converted. Pyridoxal 5'-phosphate is the active form of B6. Betaine (trimethylglycine) is a direct methyl donor. Additionally, third-party testing and manufacturing standards are important. THORNE performs four rounds of testing on every product, from raw materials to finished goods, ensuring purity and potency. The formula is also free from gluten, dairy, and soya, making it suitable for sensitive individuals.

FAQs About Methylation and Homocysteine

What is homocysteine? Homocysteine is an amino acid produced in the body. Normal levels are important for health; elevated levels may be a risk factor for cardiovascular issues.
How does Methyl-Guard Plus support healthy homocysteine? It provides the methyl donors and cofactors needed to convert homocysteine to methionine, a process that requires folate, B12, B6, and betaine.
Can I take this with other supplements? Generally yes, but due to the presence of B6 (which has an upper limit), consult a health care provider to avoid exceeding safe levels.
Is this suitable for vegetarians? The ingredients are plant-derived; check the product label for capsule composition details.
