This supplement is good for people who do NOT get enough nuts, greens, and fish on a daily basis. Wholemega is not a substitute for Omega 3 supplements that provide higher amounts of EPA and DHA. These capsules are a bit of a challenge to swallow (I recommend something thick like Slimfast or V8) and can give a bit of a fishy aftertaste. I take both the Wholemega and Omega 3 supplements daily (for a total of 2 grams of Omega oils) but have to watch for low blood pressure and excessive bleeding because I already eat a diet high in salmon, nuts, and greens. I've only taken the Wholemega for a couple of weeks but the most obvious changes from five years of Omega 3 supplements have been thicker hair growth and fewer problems with osteoarthritis. My heart is healthy and my vision and memory haven't gotten any worse but the supplements haven't prevented recurring skin cancers. Nutrition Action has a great article online titled "Omega Medicine? - Is fish oil good for what ails you?" Here's their bottom line: So far, there's decent evidence that DHA and EPA--the omega-3 fats in fish oil--can reduce your risk of a Heart attack, but not your risk of cancer, memory loss, or macular degeneration. - Eat fatty fish like salmon twice a week. That would supply 500 to 1,000 mg a day of DHA plus EPA. - If you're a vegetarian, look for foods or supplements with DHA from algal oil. - If you have heart disease, follow the American Heart Association's advice to take 1,000 mg a day of DHA EPA from fish oil. If you have side effects like burping, take them at bedtime or ask your doctor for a prescription for pure fish oil. - Taking more than 3,000 mg a day of DHA plus EPA may cause bleeding. Addendum: After 10 years of taking 2 to 3 grams of omega three daily, I've developed Afib. Research suggests that taking high dosages of EPA might be a preciptating factor of Afib (search NIH database). I'm switching to a version that is higher in DHA. 2015 Addendum: I switched to Now Foods DHA-500 and the Afib has been under control for two years. I still take an additional 2 grams of whatever omega 3 Costco has on sale. 2016 Addendum: Prompted by comments to this post, I again reviewed scientific research of the effect of omega 3 oils on AFIB and found lots of conflicting results and conclusions. A 2008 meta-analysis of 12 controlled studies "...showed that fish oil supplementation did not have a significant effect on arrhythmias and all-cause mortality." clinicalcorrelations.org/?p=8650
