MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The use of high dose vitamin supplementation is popular in parts of the population, often without any clear indication and in the absence of clear evidence of benefit.

However, side effects can occur, and in a previous published secondary analysis of double blinded randomized controlled trials, we found to our surprise an increased risk of hip fracture in those supplemented with high doses of vitamin B6 in combination with vitamin B12.

This finding was re-assessed in the current study employing data from the large observational Nurses’ Health Study. As in the previous study, we found that a combined high intake of vitamin B6 and B12 was associated with increased risk of hip fracture. Continue reading

Response: There are many anecdotal reports of vitamin B6 being used to enhance dream recall, and poor dream has sometimes been considered a possible sign of vitamin B6 deficiency by some clinicians. However, until now there was only a single study that investigated this scientifically. This was a small pilot study in 2002 that included only 12 participants. My new study now provides the strongest evidence to date that vitamin B6 does in fact enhance dream recall. The double-blind placebo-controlled study included 100 participants from around Australia who took either Vitamin B6, a B vitamin complex (with a range of other B vitamins as well), or placebo directly before bed for five days. Participants recorded their dream recall using a logbook containing a range of measures each morning. Results showed the people who took B6 recalled around 64% more content from their dreams on average compared to the placebo group, and that this had no negative impact on sleep quality.
