Your body is made of trillions of cells. Each one contains important omega-3 fatty acids that help it function normally, and that your body needs to stay healthy. But the body can’t produce omega-3s on its own, which is why we rely on two main sources to get adequate omega-3s: plants (like flax) and green vegetables, and cold-water fish or algae. Both are beneficial, but the marine sources are far superior. Here’s why. Flax contains alpha-linolenic acid (ALA), which converts to the two primary fats that have been shown to benefit health, EPA and DHA. Research shows that even under optimal lifestyle and health conditions, only about 5% of ALA converts to EPA, and just 1% converts to DHA. Simply put, a 10-ounce bag of flax-meal from your local grocery store has the equivalent EPA+DHA as a single serving of Ballstad fish oil.
