In a long-term randomized, double-blind, placebo-controlled study among sufferers of cerebrovascular accidents at high risk of depression, daily supplementation with 2 mg of folic acid, 25 mg of vitamin B6, and 500 g vitamin B 12 significantly lowered the risk of major depressive episodes during a seven-year follow-up period compared to placebo (111)
Dose Range: 250 mcg (0.25 mg) to 2400 mcg (2.4 mg) weekly with stepwise titration every 4 weeks to improve tolerability

This matters particularly during cold winter months when extended transit could subject peptides to temperature extremes
