I've been using these for years - religiously, after my breakfast. This morning, however, I found out quickly that the directions do not lie. TAKE WITH FOOD! I threw up within 5 minutes of taking one on an empty stomach. Other than that, these seem to do the trick. No crazy percentages of your DV like many vitamins have. They are a bit difficult to swallow, too.
