Never remember your dreams? There is a vitamin for it and it can even help you control them.
Adelaide University's research has found that taking vitamin B6 can help people remember their dreams.
B6 naturally occurs in whole grains, legumes, fruits like banana and avocado and vegetables, including spinach and potato.
It is also found in milk, cheese, eggs, red meat, liver and fish.
For the study, 100 participants from all of Australia took high dose vitamin B6 supplements before going to bed for five consecutive days.
Research writer Dr Denholm Aspy said the results showed that B6 improved people's ability to regain dreams.
"Vitamin B6 does not affect the vividness, bizarreity or color of their dreams and did not affect other aspects of their sleep patterns," he said.
"This is the first time that such a study of the effects of vitamin B6 and other B vitamins on dreams has been performed on a large and diverse group of humans."
The randomized, double-blind, placebo-controlled study had participants who took 240 mg vitamin B6 immediately before bedtime.
Before taking dietary supplements, many of the rarely remembered their dreams, but reported improvements at the end of the study.
Dr Aspy said the results could help people with "clear" dreams, a kind of dream where the sleeping person knows that they dream and are able to control what's happening.
"The average person spend about six years of their lives dreaming," he said.
"If we are able to get ready and control our dreams, then we can use our dream time more productively. It may be possible to use clear dreams to overcome nightmares, treat phobias, creative problem solving, refining motor skills and even help with rehabilitation from physical trauma.
"In order to get well dreams, it is very important first to recall dreaming on a regular basis. This study suggests that vitamin B6 can be a way to help people with clear dreams.
"Further studies are necessary to investigate whether the effects of vitamin B6 vary according to the amount of diet. If vitamin B6 is effective only for people with low dietary intake, its effects on dreams can reduce with long-term (use) . "
