Avena Sativa Health Benefits
Avena sativa health benefits include helping with erectile dysfunction and sexual function and increasing testosterone levels in men. Also known as wild oats, avena sativa is sometimes used as a sedative in supplement form.
Among the other reported avena sativa health benefits is an ability to assist in premature ejaculation treatment. No scientific studies support these claims, however. On a nutritional level, avena sativa seeds are a rich source of carbohydrates and fiber, as well as iron, manganese, and zinc. Supplements of avena sativa are sometimes used to enhance libido in both men and women.
In a study of possible avena sativa health benefits, researchers evaluated an extract from oats called avenacosides. This extract reportedly can enhance the release of luteinizing hormone, which then stimulates production of testosterone. (Fukushima 1976) Manufacturers of avena sativa supplements typically claim that avena sativa extract decreases sex hormone binding globulin (SHBG). This action then releases bound testosterone to free testosterone in the blood, which makes testosterone more active. However, no published studies support these claims. Anecdotal evidence suggests avena sativa is a mild sexual enhancer and may work best along with stronger herbs such as tribulus terrestris and horny goat weed. (Sahelian)
One of the more recent studies of possible avena sativa health benefits involved use of the supplement in people with mild cognitive impairment. Elderly volunteers with below-average cognitive function were given different doses of oat extract. The authors reported that a dose of 1,600 mg daily may improve attention and concentration. However, much more research is needed.
