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.
50 to 100 mg daily
Supplementing with royal jelly may lower cholesterol levels.
Royal jelly has prevented the cholesterol-elevating effect of nicotine1 and has lowered serum cholesterol in animal studies.2 Preliminary human trials have also found that royal jelly may lower cholesterol levels.3 , 4 An analysis of cholesterol-lowering trials shows that 50 to 100 mg per day is the typical amount used in such research.5
Royal jelly in the amount of 50–100 mg per day has been used in most of the studies on cholesterol lowering.
Royal jelly is available in liquid form (usually in glass vials), tablets, and capsules.
Because royal jelly is not an essential nutrient, deficiencies do not occur.
Allergic reactions are the most common side effect. Allergic reactions from oral intake of royal jelly can range from very mild (e.g., mild gastrointestinal upset) to more severe reactions, including asthma, anaphylaxis (shock), intestinal bleeding, and even death in people who are extremely allergic to bee products.6 , 7 , 8 People who are allergic to bee pollen, honey, or conifer and poplar trees should not use royal jelly orally. Topical use of royal jelly has been reported to cause skin irritations in some people.9
