The biggest problem with Reliv, and similar MLM products, is that they are way overpriced for what they are, because their priority is $$$. They really aren't any better quality than similar products you may buy at Vitamin Shoppe. I just browsed their nutrition/ingredient labels and didn't see anything that should warrant such high prices. You don't get anything more than you would get if you took a cheap daily multi-vitamin tablet, except for the 7 grams of protein in the powder. A glass of skim milk will give you that.
I don't know anyone that has used their products. But I'm concerned that regular vitamins make you sick to your stomach. Have you spoken to your doctor about this? S/he may be able to pin down the problem. Most regular multi-vitamins should be fine, especially if you take them with a meal. Some of the mega-dose vitamins may cause problems, because high dosages of some vitamins or minerals can cause an upset stomach. A regular One-a-Day type vitamin is all most of us need. But the One-a-Day Weight Smart makes a lot of people sick.
Berkeley Wellness has a good guide to choosing vitamins on their site at http://www.berkeleywellness.com/html...tivitamins.php
Dr. Weil (and several other references I checked) suggests that the iron may be the culprit in this article
so you want to try a vitamin without iron.
