Folate-Dependent Remethylation This process converts homocysteine back into methionine and helps keep base levels of homocysteine low ( Three nutrients are needed to keep this system running smoothly: Folate
In a recent study, Zilocchi et al
Clinical human data is extremely limited
Acute toxicity studies in animals, if extrapolated to humans, implicate a single dose of 10-15 grams necessary to produce significant liver toxicity, although several human case reports have shown toxicity at doses less than 4 grams per day (likely due to having one or more risk factors for sensitivity to toxicity) (Amar 2007)
Suppliers offering volume-based discounts (e.g., $4 per gram for 1,000+ grams) significantly reduce unit costs for large-scale production
Timing considerations Most protocols recommend evening administration, 30-60 minutes before intended sleep
