At the Institute for Optimum Nutrition, we found that the specific B vitamin related to dream recall is B6, but B vitamins do work together so it' s best to take a complex plus extra B6. I' d recommend 50mg B complex with breakfast and dinner (either as a B complex or in a multi), plus 50mg B6 at breakfast, lunch and dinner (totaling 250mg of B6), and 15 mg zinc with breakfast. If this doesn' t work, take an additional 50mg B6 before bed. Also reduce your alcohol intake and stress levels, and eat vitamin B-rich foods (wholegrains, brewer' s yeast, lentils, most vegetables). One last thing... many people are reporting better dream recall with a supple-ment called Connect.
