The health benefits of fish oil is not 'new' news. In fact, use of cod liver oil for immune defense dates back to at least the 1800s, and perhaps even further. Today, we know much more about the science of nutrients, and we also know that the benefits of cod liver oil are actually linked to immune balance.

The thing is, fish oil has grown up to be QUITE the industry. Visit the wellness aisle of any store and you're bound to see a variety of brands on offer. How do you choose? Our advice: choose carefully. What's in those bottles can vary widelyfrom the species of fish, to the habitat in which it was caught, to the method of processing, and ultimately to the nutrient content of the product you find in your hands.

Big Bold Health's Healthy Aging Advisor Dr. Jonny Bowden explains all of these things in this short tutorial video about Dutch Harbor Omega Maintain, our best-in-class, purity-tested Alaskan cod liver oil.
