About 5-MTHF – 5mg / 60 Capsules

Unlock the full benefits of folate with Thorne’s 5-MTHF (5-Methyltetrahydrofolate).

Unlike synthetic folic acid, which requires a multi-step enzymatic conversion to become active, 5-MTHF is the predominant, ready-to-use form of folate found in the bloodstream. This makes it the superior choice for individuals, including those with common genetic variations (such as MTHFR), who may have difficulty efficiently converting folic acid.

This supplement features Quatrefolic®, a premium, well-researched form of 5-MTHF that is highly stable and bioavailable. Each capsule delivers a potent 5 mg dose to support critical bodily functions, including DNA synthesis, neurotransmitter production, and cardiovascular health.

By providing folate in its active form, Thorne ensures your cells can immediately utilize this vital nutrient for optimal health from the moment you take it.

Benefits Overview

  • Active Form of Folate: Provides 5-MTHF, the body’s ready-to-use form of folate, bypassing the need for conversion.
  • Ideal for MTHFR Support: A crucial supplement for individuals with MTHFR gene variations who have difficulty processing synthetic folic acid.
  • Neurological & Mood Support: Plays a key role in the production of neurotransmitters like serotonin and dopamine.
  • Cardiovascular & Prenatal Health: Supports healthy homocysteine metabolism for heart health and is critical for fetal development.
  • High-Quality Ingredient: Features the patented Quatrefolic® for guaranteed purity and stability.

Supplement Use

Take 1 capsule one to three times daily or as recommended by your healthcare practitioner.

Since individual needs vary, especially regarding MTHFR status, it is best to consult with a healthcare provider to determine the optimal dosage for you.
