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.

Flavonoids, phenolic acids, and other compounds appear to be responsible for lemon balm’s anti-herpes and thyroid-regulating actions. Test tube studies have found that lemon balm blocks attachment of antibodies to the thyroid cells that cause Grave’s disease (hyperthyroidism).2 The brain’s signal to the thyroid (thyroid-stimulating hormone or TSH) is also blocked from further stimulating the excessively active thyroid gland in this disease. However, clinical trials proving lemon balm’s effectiveness in treating Grave’s disease are lacking.

The effectiveness of the herbal combination was similar to that of Halcion, as determined by the ability to fall asleep and the quality of sleep.3 Another trial also found that the same combination of valerian and lemon balm, taken over a two-week period, is effective in improving quality of sleep.4
