 fish oil you need to do that when you're dealing with krill because krill just isn't high enough in omega-3 so many other important parameters and virtues but you got to get that high omega-3 fish oil in there and we've done that so this is now the best of both worlds but we didn't stop there for the 50 plusers we've added some vitamin d we doubled the antioxidant power and steve we actually increased the amount of krill by 67 so this now becomes the finest omega-3 nutrient in the world as far as i'm concerned
