Flax seed is an excellent plant-based source of omega-3 fatty acids, particularly alpha-linolenic acid (ALA). However, ALA needs to be converted into the active forms of omega-3s (EPA and DHA) in the body, which can be less efficient than consuming fish oil directly. Fish oil contains pre-formed EPA and DHA, which are the forms of omega-3s that offer the most immediate benefits for heart and brain health.
For individuals following a plant-based or vegan diet, flax seed is a great alternative to fish oil for omega-3 intake. However, if you're not restricted by dietary preferences, fish oil may provide more direct omega-3 benefits. Both flax seed and fish oil can be beneficial, and incorporating both into your diet may provide a well-rounded approach to omega-3 supplementation
