Hemp seed oil is an edible oil extracted from the seeds of the hemp plant. It is commonly used as a dietary supplement, due to its high content of Omega-3 and Omega-6 fatty acids, as well as other nutrients, such as vitamin E and magnesium. Hemp seed oil is also used in the production of cosmetic and other products, but it is not typically used for cooking or frying due to its low smoke point. When used as a supplement, hemp seed oil is often taken in liquid form or as a capsule, and is marketed for its potential health benefits, including reducing inflammation, improving heart health, and supporting brain function. Additionally, hemp seed oil is a good source of plant-based protein, making it a useful ingredient for vegans and vegetarians. However, it is important to note that hemp seed oil does not contain significant amounts of the psychoactive compound THC, which is found in other parts of the hemp plant.
