Health Notes


This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

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.

Herbal supplements can help strengthen the immune system and fight infections. Adaptogens, which include eleuthero, Asian ginseng, astragalus, and schisandra, are thought to help keep various body systems-including the immune system-functioning optimally. They have not been systematically evaluated as cold remedies. However, one double-blind trial found that people who were given 100 mg of Asian ginseng extract in combination with a flu vaccine experienced a lower frequency of colds and flu compared with people who received only the flu vaccine.1

Immune Function
Dose: Refer to label instructionsComplex polysaccharides present in astragalus and in maitake and coriolus mushrooms appear to act as "immunomodulators" and, as such, are being researched for their potential role in AIDS and cancer. Presently, the only human studies on astragalus indicate that it can prevent white blood cell numbers from falling in people given chemotherapy and radiotherapy and can elevate antibody levels in healthy people.1 Maitake has only been studied in animals as a way to increase immune function.2 The primary immuno-activating polysaccharide found in these mushrooms, beta-D-glucan, is well absorbed when taken orally3 and is currently under investigation as a supportive tool for HIV infection. Results from future research will improve the understanding of the possible benefits of these mushrooms and their constituents.

Dose: Refer to label instructions

Herbs that support a person's immune system in the fight against microbes include the following: American ginseng, andrographis, Asian ginseng, astragalus, coriolus, eleuthero, ligustrum, maitake, picrorhiza, reishi, schisandra, and shiitake.1

Dose: Refer to label instructions

One Chinese preliminary trial also found that astragalus could decrease overactive immune function in people with systemic lupus erythematosus.1 However, much more research is needed to know whether astragalus is safe in lupus or any other autoimmune disease.

Heart Attack
Dose: Refer to label instructionsPreliminary clinical trials in China suggest that astragalus may be of benefit in people after they have suffered a heart attack.1, 2 These studies did not attempt to show any survival or symptom reduction benefit. Therefore, further research is needed to determine whether astragaslus would be of benefit to people with heart attacks or angina.

Parts Used & Where Grown

Astragalus is native to northern China and the elevated regions of the Chinese provinces, Yunnan and Sichuan. The portion of the plant used medicinally is the four- to seven-year-old dried root, collected in the spring. While over 2,000 types of astragalus exist worldwide, the Chinese version has been extensively tested, both chemically and pharmacologically.1
