What Is Methyl-Guard Plus?
Methyl-Guard Plus is Thorne’s premium methylation support supplement, providing therapeutic doses of methylfolate (5-MTHF), methylcobalamin (B12), pyridoxal-5-phosphate (active B6), and riboflavin-5-phosphate (active B2). These are the active, body-ready forms of key B vitamins that individuals with MTHFR mutations or impaired methylation cannot efficiently produce from standard supplements. Healthy methylation is essential for cardiovascular function, neurotransmitter production, detoxification, and gene expression.*
Key Benefits
- Supports healthy homocysteine metabolism for cardiovascular protection*
- Provides active methylated B vitamins that bypass MTHFR gene variants*
- Promotes neurological health and neurotransmitter synthesis*
- Supports detoxification, DNA methylation, and mood regulation*
- Formulated with activated, bioavailable forms for those with methylation challenges
Who Should Take This?
Methyl-Guard Plus is specifically indicated for individuals with known MTHFR mutations (C677T or A1298C), elevated homocysteine levels, or family histories of cardiovascular disease, depression, or neural tube defects. It is also highly relevant for those who have not responded to standard B-vitamin supplementation and for women of childbearing age who require optimal folate status.*
How to Use
- Serving Size: As directed by your healthcare provider — typically 1–2 capsules daily
- Timing: Take with a meal to minimize any B-vitamin-related nausea
- Duration: Ongoing daily use for sustained methylation support; retest homocysteine at 3–6 months
- Stacking: Often paired with omega-3s and magnesium as part of a cardiovascular and neurological support protocol
Our Doctors’ Take
Our doctors consider Methyl-Guard Plus one of the most clinically significant supplements we carry. MTHFR variants are remarkably common, and most people have no idea they have one — yet it affects everything from cardiovascular risk to mental health to detoxification capacity. Thorne is one of the few supplement brands that consistently meets pharmaceutical-grade manufacturing standards, which is why we trust this formula for such a targeted application.
