New Roots Herbal Wild Omega 3 - Pharmaceutical-grade pure fish oil sourced only from anchovies and sardines. Wild Omega 3 fish oil helps improve cognitive function, supports heart health, and reduces inflammation. Fish oil is probably the most important dietary source of omega-3 fatty acids, which are vital nutrients. Omega-3 fatty acids are one type of essential fatty acids, special fats that the body needs as much as it needs vitamins. Much of the research into the potential therapeutic benefits of omega-3 fatty acids began when studies of the Inuit people found that, although their diets contain an enormous amount of fat from fish, seals, and whales, they seldom suffer heart attacks or develop rheumatoid arthritis; this is presumably because those sources of fat are very high in omega-3 fatty acids.
