Overview
Alpha-linolenic acid (ALA) is an essential omega-3 fatty acid found in nuts such as walnuts. It is necessary for normal human growth and development.
Alpha-linolenic acid is thought to decrease the risk of heart disease by helping to maintain normal heart rhythm and pumping. It might also reduce blood clots. Common dietary sources include vegetable oils such as flaxseed and canola oil, as well as red meat and dairy products.
Alpha-linolenic acid is most commonly used for diseases of the heart and blood vessels, such as hardening of the arteries, heart disease, and high blood pressure. It is also used for other conditions, but there is no good scientific evidence to support most of these uses.
You have probably heard a lot about other omega-3 fatty acids such as EPA and DHA, which are found in fish oil. Alpha-linolenic acid may not have the same benefits as EPA or DHA. Be careful not to confuse alpha-linolenic acid with these other omega-3 fatty acids.
