Product education

L-Methylfolate: Highly Bioavailable Folate Support*

L-Methylfolate provides a high-potency dose of folate in its most bioactive form: Metafolin® L-5-methyltetrahydrofolate (L-5-MTHF). This active, methylated form of folate is crucial for a variety of essential bodily processes, including methylation, DNA biosynthesis, homocysteine metabolism, and nervous system function. It is an ideal choice for individuals who may have genetic variations that make it difficult to efficiently convert standard folic acid into its active form.

How It Works: Bypassing the Conversion Process

This formula delivers folate in a form that is directly usable by the body, ensuring maximum benefit without the need for enzymatic conversion.*

Support for Methylation and Homocysteine
Methylation is a fundamental process that impacts nearly every cell in the body. L-5-MTHF is a primary methyl donor, which is critical for supporting cardiovascular health by helping to maintain healthy homocysteine levels. It also plays a key role in the synthesis of neurotransmitters that regulate mood.*

Foundational for Cellular Health
As a key nutrient in DNA biosynthesis, folate is essential for healthy cell growth and replication. By providing the body-ready form, this supplement ensures this vital nutrient is available to support foundational cellular processes and overall nervous system health.*

  • Features the highly bioavailable, active form of folate as Metafolin® L-5-MTHF*
  • Supports healthy methylation and homocysteine metabolism*
  • Essential for DNA biosynthesis and nervous system function
  • Ideal for those who have difficulty converting standard folic acid
  • A clean, hypoallergenic formula free of common allergens
