Krill oil

Krill oil is derived from tiny marine crustaceans called krill. If you’ve spent many a Friday night watching BBC nature docs, you know (thanks to Sir David Attenborough, no doubt) that baleen whales gobble up these crustaceans by the millions. Well, those whales definitely know a healthy snack when they inhale one! Krill are a fantastic source of vital fatty acids, aka “good fats,” called omega-3s. There’s even anecdotal evidence that omega-3s from krill are more bioavailable than those found in fish oil, though more research needs to be done to prove it. A quick rundown of the benefits of omega-3s: Studies suggest they improve symptoms of depression and anxiety and boost heart and possibly brain health. They’re especially beneficial to people with autoimmune conditions, like rheumatoid arthritis, Crohn's disease, UC, psoriasis, lupus, and multiple sclerosis, as well as migraines. Think of it this way: You are essentially using omega-3s to replace a deficiency created by our Western diet, which tends to result in too many omega-6s and not enough omega-3s. Omega-6s (another essential fatty acid found in corn, soy, hydrogenated oils, and more) contributes to inflammation and chronic illness—including those autoimmune conditions. Consuming more omega-3s can shift the balance back toward 1/1, which is the healthy ideal. Many health experts say most people should eat oily fish (like salmon, sardines, and mackerel) about twice a week, because they’re some of the best source of omega-3s. The reason? The human body doesn't make omega-3s, but…let’s be real, these fish may not be your go-to meal too often. While you work toward eating more of them, you can always supplement with fish oil, though some people are opting for the new kid on the block—krill oil.
