Hemp seed oil is generally taken orally and is used as a natural supplement. It contains vitamins, sterols, aliphatic acids and linolenic acids, including omega-3 fatty acids, according to Medical News Today. These components of hemp seed oil are known to promote heart health and have other positive effects.
Hemp seed oil contains a number of essential vitamins and nutrients, including beta-carotene, vitamin A, vitamin C and vitamin E. The omega-3 fatty acids in hemp seed oil are known to prevent coronary heart disease, states Medical News Today.
The sterols found in hemp seed oil are linked to lower cholesterol levels, explains Medical News Today. Tocopherol, an antioxidant found in hemp seed oil, is thought to fight degenerative diseases such as Alzheimer's disease and atherosclerosis.
Hemp seed oil is extracted from the seeds of Cannabis sativa, a relative of marijuana, according to Reuters. In addition to the omega-3 fatty acids, hemp seed oil also contains omega-6 fatty acids. The omega-3 fatty acid in hemp seed oil is known as alpha-linolenic acid. In addition to preventing heart disease, alpha-linolenic acid is also thought to prevent cancer, states Reuters.
While the benefits of using hemp seed oil seem promising, Reuters explains that, according to its professional sources, there is no hard scientific proof of the benefits of hemp seed oil.
