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.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Colostrum appears to be useful in treating certain types of infectious diarrhea. In one study, it significantly reduced diarrhea and the amount of oral rehydration required.
Colostrum might be useful for certain types of infectious diarrhea. In a double-blind trial, children with diarrhea caused by a rotavirus were treated with immunoglobulins extracted from colostrum derived from cows immunized with rotavirus. Compared with the placebo, colostrum extract significantly reduced the amount of diarrhea and the amount of oral rehydration solution required. The rotavirus was eliminated from the stool significantly more rapidly in the colostrum group than in the placebo group (1.5 days, vs. 2.9 days).1
In addition to a positive effect against acute rotavirus diarrhea,2 there is also evidence that specific forms of colostrum (derived from specially immunized cows or those with confirmed presence of specific antibodies) are effective against diarrhea caused by Cryptosporidium parvum, Helicobacter pylori, Escherichia coli, and Clostridium difficile.3 , 4 , 5 , 6 , 7 However, it is not known whether commercially-available colostrum provides significant amounts of the specific immunoglobulins that are active against these organisms. Furthermore, unless the immunoglobulins are present in high enough concentrations, the preparation is not likely to be effective.8
Most manufacturers recommend 1,000 to 4,000 mg per day of freeze-dried colostrum.
Bovine colostrum is available in capsules, tablets, powdered drink mixes, liquid preparations, food bars, and skin care products.
As bovine colostrum is not an essential nutrient, no deficiency state exists.
