eBayTriquetra Health L-Methylfolate 15mg + B12 Cofactor — Liquid Drops, Organic Berry, 1 fl oz High-Potency Active 5-MTHF | Methylation Support | For Adults with MTHFR Variations
Brand new, factory sealed. Fast shipping with tracking.
Triquetra Health L-Methylfolate Liquid Drops deliver a clinical-strength 15 mg (15,000 mcg) dose of L-Methylfolate (5-MTHF) — the active, bloodstream-ready form of folate — paired with its essential cofactor, Methylcobalamin B12, in a delicious organic berry-flavored liquid. This is Triquetra's highest-potency methylfolate formula, designed for adults with significant MTHFR gene variations, methylation pathway concerns, or those whose practitioners have recommended a high-dose protocol.
For anyone who's tried standard 400-mcg folic acid or 1-mg methylfolate without satisfactory results — and who's been told by a functional medicine doctor or genetic test that they need more aggressive methylation support — this is the formula built for that need.
Why customers choose it:
What is L-Methylfolate (5-MTHF)?
Folate (vitamin B9) is essential for many of the body's most important processes — including neurotransmitter production (serotonin, dopamine, norepinephrine), DNA synthesis, methylation reactions, and cellular health. Most folate supplements use synthetic folic acid, which the body has to convert into L-Methylfolate (the active form) before it can be used.
People with MTHFR gene variations (especially C677T and A1298C polymorphisms) have a significantly reduced ability to make this conversion — meaning standard folic acid supplements may not fully reach the bloodstream in usable form, regardless of dose. L-Methylfolate skips the conversion step entirely. It's already in the active form — ready for the body to use directly.
Why a high-dose 15 mg formula?
For people with significant MTHFR variations, lower-dose methylfolate (400 mcg–1 mg) may not provide adequate methylation support. Published research on MTHFR-related mood and methylation issues has used doses in the 7.5–15 mg range. Triquetra's 15 mg formula is designed to meet that need in a single daily dose — though many users titrate up gradually under practitioner guidance.
Why B12 is essential alongside Methylfolate:
L-Methylfolate cannot complete its work in the body without Methylcobalamin B12. The two nutrients work together in the methylation cycle — methylfolate is the fire, and B12 is the firewood. Triquetra's formula includes both in their active, bioavailable forms, ensuring complete methylation support in one bottle.

How to use:
A note on starting high-dose methylfolate: Some people experience what's called a "methylation reaction" when first starting high-dose methylfolate — symptoms can include irritability, anxiety, headache, or mood changes. This is more likely at higher doses and is a known phenomenon in functional medicine. For this reason, working with a knowledgeable practitioner is strongly recommended for the 15 mg dose. Start with a small fraction of a dropperful and increase gradually.
