- Reliable and relatively consistent scientific data showing a substantial health benefit.
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.
This supplement has been used in connection with the following health conditions:MenopauseDose: 4 to 6 grams daily of dried herb or equivalentSupplementing with sage leaf and alfalfa extract completely eliminated hot flushes and night sweats in 20 of 30 women in one study.(more)MenopauseDose: Refer to label instructionsAlfalfa, an herb with weak estrogen-like actions similar to the effects of soy, has traditionally been used for women with menopausal symptoms.(more)High CholesterolDose: Refer to label instructionsSaponins in alfalfa seeds may block cholesterol absorption and prevent the formation of atherosclerotic plaques.(more)MenopauseDose: 4 to 6 grams daily of dried herb or equivalentSage may reduce excessive perspiration due to menopausal hot flashes during the day or at night.1 It is believed this is because sage directly decreases production of sweat. In a preliminary study, supplementation with a product containing extracts of the leaves of sage and alfalfa resulted in complete elimination of hot flushes and night sweats in 20 of 30 women, with varying degrees of improvement in the other ten cases.2ReferencesMenopauseDose: Refer to label instructions
A variety of herbs with weak estrogen-like actions similar to the effects of soy have traditionally been used for women with menopausal symptoms.1 These herbs include licorice, alfalfa, and red clover. In a double-blind trial, a formula containing tinctures of licorice, burdock, dong quai, wild yam, and motherwort (30 drops three times daily) was found to reduce symptoms of menopause.2 No effects on hormone levels were detected in this study. In a separate double-blind trial, supplementation with dong quai (4.5 grams three times daily in capsules) had no effect on menopausal symptoms or hormone levels.3 A double-blind trial using a standardized extract of subterranean clover (Trifolium subterraneum), a relative of red clover, containing 40 mg isoflavones per tablet did not impact symptoms of menopause, such as hot flashes, though it did improve function of the arteries.4 An extract of red clover, providing 82 mg of isoflavones per day, also was ineffective in a 12-week double-blind study.5 In another double-blind study, however, administration of 80 mg of isoflavones per day from red clover reduced the frequency of hot flashes in postmenopausal women. The benefit was noticeable after 4 weeks of treatment and became more pronounced after a total of 12 weeks.6References

Animal studies indicate that saponins in alfalfa seeds may block absorption of cholesterol and prevent the formation of atherosclerotic plaques.1 However, consuming the large amounts of alfalfa seeds (80 to 120 grams per day) needed to supply high doses of these saponins may potentially cause damage to red blood cells in the body.2References
