what are the best vitamins for weight loss?

First, I am not totally sure that vitamins in pill form are fully absorbed by the body. But, just in case, I try to take a multivitamin everyday.

Second, you may want to ask your doctor to check to see if you have a vitamin deficiency. For some reason, I have a vitamin d deficiency. Occasionally, my doctor gives me a Rx for a vitamin d supplement. I don't know whether it helps with my weight loss, but it helps my body absorb the calcium it needs. Plus, I seem to feel better.

Finally, I think that the best advice is to get your vitamins from the foods that you eat. Eat a wide variety of foods. Different color fruits and vegetables offer different vitamins. There are excellent lists compiled on this thread. And, whether there are "negative calorie" foods or not, eating those vegetables certainly won't hurt you.
