Flaxseed oil is derived from the seeds of the flax plant, known scientifically as Linum usitatissimum. It is rich in omega-3 fatty acids, particularly alpha-linolenic acid (ALA), which is beneficial for heart health and may help reduce inflammation in the body. This oil is often used as a dietary supplement and can be added to smoothies, salad dressings, or taken in capsule form. However, it is sensitive to heat and light, so it should be stored in a cool, dark place and not used for cooking at high temperatures.
