How Does CARDIO3 Work?

The three types of omega-3s include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Omega 3s are fatty acids that are part of the membrane surrounding the cell, so they play an essential protective role.

Our bodies are not capable of producing ALA and can only make small amounts of EPA and DHA, so we have to get it from food or from a supplement. According to the Harvard H. Chan School of Public Health, omega 3 has many health benefits including treating heart disease and stroke, controlling lupus, eczema, and rheumatoid arthritis, and it may also play protective roles in cancer and other conditions.

Others say that there’s little solid evidence to back up these claims, states a review in The Conversation.

However, the American Heart Association still recommends including plenty of fish in your diet, so you get your omega 3s.
