1MG L-5 MTHF by Intelligent Labs, 120 Capsules 4 Months Supply, L-5 Methylfolate Activated Folic Acid Supplement as Quatrefolic Acid, Activated Folate
Intelligent Labs

1MG L-5 MTHF by Intelligent Labs, 120 Capsules 4 Months Supply, L-5 Methylfolate Activated Folic Acid Supplement as Quatrefolic Acid, Activated Folate

  • ★ Pure 5-MTHF ★ If you have an MTHFR problem, our supplement will most likely help you. We use the scientifically advanced 5-MTHF Quatrefolic Acid developed by Gnosis. Each bottle contains 60 capsules, your order should last you about 2 months - excellent value for your money!
  • ★ 4th generation activated folate ★ Quatrefolic Acid is the 4th level of development in folate supplements. It is stable, pure, and better absorbed than other 5-MTHF because it's bound to glucosamine instead of calcium.
  • ★ Quatrefolic acid ★ Activated folate goes by a lot of names and can be quite confusing. Our supplement is Quatrefolic Acid, a trademarked supplement 5-MTHF. It is also referred to as 6 (S)-L-MTHF also known as L-5, and chemically similar to metafolin or l-methylfolate calcium except the methylfolate is bound to glucosamine (non shellfish derived) instead of calcium. So if you have been told to look for any of these, you are in the right place.
  • ★ High Strength ★ Each vegetarian capsule contains 5mg of activated folic acid. Folate supplementation contributes to the reduction of tiredness, normal homocysteine metabolism, normal psychological and immune system function, and increases maternal folate status which reduces the risk of neural tube defects in babies.
  • ★ Your health is our priority ★ Independent third-party testing, available upon request, confirms the purity, safety, and potency of our products.
