Evidence reviews

Vitamin B6 and magnesium in combination for children with autism spectrum disorder

Studies investigating the effect of vitamin B6 in improving the behaviour of children with autism spectrum disorder have been reported for over three decades. The purpose of this review was to summarize those studies and analyse the effectiveness of vitamin B6 as an intervention. Only three studies met the inclusion criteria of this review and of these only one study reported adequate data for analysis. Results were inconclusive and sample sizes were small. Therefore the use of vitamin B6 for improving the behaviour of individuals with autism cannot currently be supported. Further research using larger, well‐designed trials is needed.

Vitamin B1 and magnesium may both help reduce the pain of dysmenorrhoea

Dysmenorrhoea is a very common complaint that refers to painful menstrual cramps in the uterus. When the pain is associated with a recognised condition such as endometriosis, it is called secondary dysmenorrhoea. Primary dysmenorrhoea refers to pain of an unknown cause. Nonsteroidal anti‐inflammatory drugs or the contraceptive pill have been used but more women are looking for non‐drug therapies, including herbal and dietary treatments. The review of trials found some evidence that Vitamin B1 and magnesium help reduce pain but more research is needed.
