Research has demonstrated that a brain nutrient, required to make the sleep hormone, melatonin, can be crucial in promoting a restful sleep.
An Oxford University study revealed that DHA, a fatty acid, often derived from fatty fish and in cod liver oil, is instrumental in promoting the sleep hormone, melatonin. DHA is so necessary, that blood levels revealed that low levels of DHA increased the likelihood of a restless sleep. Moreso, when DHA was administered to a control group compared to a placebo group that recieved no DHA, the DHA group experienced less wakings and slept one hour longer.
Restorative sleep is necessary for brain function and recovery. This is excellent research disclosing the added benefits of DHA to support sleep, in addition to its benefits of increasing brain productivity and reducing inflammation.
