What is the recommended dosage for Folate?

General: 400 mcg DFE/day (RDA); Cognitive Support: 400-800 mcg/day

What are the side effects of Folate?

Potential side effects include: Generally well-tolerated, May mask B12 deficiency symptoms, Rare: insomnia or irritability at high doses.

Folate (vitamin B9) is an essential B vitamin involved in DNA synthesis, methylation reactions, and neurotransmitter production. Adequate folate status is important for brain health, and deficiency has been associated with elevated homocysteine levels and cognitive concerns in older adults.

What dosage of Folate has been used in cognitive studies?

Cognitive studies have used 400 mcg to 800 mcg of folate daily, often in the methylfolate (5-MTHF) form for better bioavailability. Some studies have combined folate with vitamin B12 and B6. The tolerable upper intake for synthetic folic acid is 1,000 mcg per day. Consult your doctor.

What are the potential side effects of Folate?

Folate from food and methylfolate supplements is generally safe. High-dose folic acid (the synthetic form) may mask vitamin B12 deficiency symptoms and has been studied for potential concerns at very high intakes. Consult your healthcare provider for appropriate dosing.

About

Folate is a critical cofactor in the homocysteine-methionine cycle, supporting SAM production essential for neurotransmitter synthesis and DNA methylation. Combined with B12, folate supplementation slowed brain atrophy rate in MCI patients.

How It Works

Critical cofactor in the homocysteine-methionine cycle; supports SAM production essential for neurotransmitter synthesis and DNA methylation; deficiency leads to elevated homocysteine associated with cerebral damage.
