This is was a great product. I had rock bottom low vitamin levels and also iron deficiency. Taking vitamins was just not helping because I was having problems absorbing vitamins the vitamins. My doctor suggested Fish Oil with DHA & EPA. After 3 month of Doctor's Best Real Krill. I had my vitamin levels retested and my vitamin raised above the level I needed to be at. Even my doctor was surprised how well I began to absorb & how my vitamins levels raised that fast in such a short period. I had tried for two years to get these vitamins level up and I just needed the Krill oil to help me with absorbing it. For those considering the product.
