I evaluated many products prior to selecting this one and in the past have tried several other omega-3-fatty acid-containing products including other krill oils, fish oils, and plant-based oils including algae oil. Small capsules are easy to swallow, but the serving size is 2 capsules (keep in mind when price-comparing), the company has a good reputation and quality reviews are solid, high potency for the price-point, no indication of rancid oils (i.e. foul scent)
I have only taken them for a month so far, but I can tell you that the taste/smell is not as bad. This seems to be the best quality for the price. It could be a coincidence, but my mind felt sharper and I was not aware that it could with this supplement. I had no poor reactions from this product whatsoever, the price is great for the quality. Be very careful when choosing anything that comes from the ocean; this is a high-quality product.
