How L-Methylfolate Works In The Body

  • Supports neurotransmitters like serotonin, dopamine & norepinephrine.*
  • Supports red blood cell production and the body’s natural detoxification processes.*
  • Helps your homocysteine levels stay in check which is vital for heart and brain health.*

Methylated Folate: A Nutrient Form Some People Prefer for Genetic Support*

Certain MTHFR gene variations may reduce how efficiently the body converts synthetic folic acid.* Methylated forms like 5-MTHF can offer a more direct form of folate support.

Methylated vitamins provide folate in a body-ready form, supporting bioavailability and cellular use.*

Clinically Validated Doses

15mg L-Methylfolate

L-Methylfolate is the bioactive form of folate (B9) that is readily utilized by the body.*

1000mcg Methyl B12

L-Methyfolate cannot do its job in the body without Methyl B12. If L-Methyfolate is the fire, think of Methyl B12 as the firewood.
