I first heard about iHerb last year, when someone in my running club promoted this website, (using his promotion code, of course). I am an American living in South Korea, so it is very hard for me to find vitamins and supplements here. I was looking for some prenatal vitamins, so I ordered some from iHerb. I was surprised at how quickly the order came, and how well packaged the products were. The price was also very reasonable compared to other companies, (especially the shipping costs). I have been hooked ever since! I believe that many health problems are linked to nutritional deficiencies. I have read many books on this topic, so most of the supplements I purchase are based on careful research. In a perfect world we would be able to obtain most of the nutrients and minerals we need from our food, but industrial agricultural methods have made this very difficult. For this reason I think supplementation is a necessary evil. If you find my reviews helpful, please rate them.
