Folate for Nutritional Deficiency Cognitive Impairment
BCritical for homocysteine metabolism and SAM production essential for neurotransmitter synthesis. MTHFR polymorphism carriers may benefit more from methylated forms (5-MTHF).
The Bottom Line
Critical for homocysteine metabolism and SAM production essential for neurotransmitter synthesis. MTHFR polymorphism carriers may benefit more from methylated forms (5-MTHF).
