Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Activated charcoal has the ability to adsorb (attach to) many substances, including gases produced in the intestine.1, 2 In a small, controlled trial, people were given a meal of gas-producing foods along with capsules containing 584 mg of activated charcoal, followed by another 584 mg of activated charcoal two hours later. Using activated charcoal prevented the five-fold increase in flatulence that occurred in the placebo group. Another, small controlled study found that taking 388 mg of activated charcoal two hours after a gas-producing meal normalized flatulence by the fourth hour.3 However, a preliminary human study found no effect on flatulence or abdominal symptoms when healthy volunteers took 520 mg of activated charcoal four times per day for one week.4

Charcoal is a fine, black powder made from wood or other natural materials by heating them in an airless environment. Charcoal used for health conditions is usually "activated" to make it a very fine powder, which increases its effectiveness. Activated charcoal can chemically attach, or adsorb, to a variety of particles and gases, which makes it ideal for removing potentially toxic substances from the digestive tract. Activated charcoal is not absorbed into the body, so it carries adsorbed substances out of the body in the feces.
