Ideally, you would get your nutrition from wholesome nutrient-dense foods. But if you think you need more nutritional support, choose the best you can. Supplements from organically grown, raw, whole foods are superior to artificial, synthetic supplements.
I recommend V E Irons products because it is still a family owned company that I have used since I was 16 years old.
I also recommend Barlean's products because their oils are freshly cold pressed when they are ordered.
