SupplementAmountWhy
Anthocyanins
> 400 mg daily3 stars[3 stars]
Taking anthocyanins may help people with metabolic syndrome achieve better blood glucose control and normalize triglyceride and cholesterol levels.
Berberine
500 mg three times daily3 stars[3 stars]
Clinical trials have shown berberine can benefit all aspects of metabolic syndrome.
Cinnamon
1 to 3 grams daily3 stars[3 stars]
Cinnamon has been shown to improve all aspects of metabolic syndrome.
Glucomannan
3 to 10 grams daily3 stars[3 stars]
Taking a glucomannan fiber supplement may improve metabolic syndrome.
Green Tea
600 to 900 mg of tea catechins daily3 stars[3 stars]
Strong evidence indicates green tea and black tea extracts can help individuals with metabolic syndrome reduce body weight, lower blood glucose levels, and raise HDL-cholesterol levels.
Guar Gum
3 to 10 grams daily3 stars[3 stars]
Taking a guar gum fiber supplement may improve metabolic syndrome.
Açaí
200 grams of berry pulp daily2 stars[2 stars]
Preliminary evidence suggests acai berry may improve metabolic health.
Chromium
200 to 500 mcg daily, or more under doctor supervision 2 stars[2 stars]
Supplementing with chromium may be beneficial in people with type 2 diabetes and metabolic syndrome.
Coenzyme Q10
30 to 200 mg daily2 stars[2 stars]
A small body of clinical evidence suggests coenzyme Q10 may improve insulin sensitivity, glucose and lipid metabolism, and blood pressure in those with metabolic syndrome.
L-Carnitine
2 to 3 grams daily2 stars[2 stars]
L-carnitine supplementation may reduce cardiovascular risk by improving metabolic parameters such as body weight, blood glucose control, insulin sensitivity, and lipid levels.
Magnesium
300 mg daily2 stars[2 stars]
People with metabolic syndrome often have low magnesium status and benefit from magnesium supplementation.
Myoinositol
1.1 to 4 grams daily; in combination supplements, the ratio of myoinositol to d-chiro-inositol is generally 40:12 stars[2 stars]
Myoinositol, alone or in combination with d-chiro-inositol, may improve some aspects of metabolic syndrome in women with polycystic ovary syndrome.
Omega-3 Fatty Acids
1 to 2 grams of fish oil, or ~300 mg of combined EPA plus DHA, daily2 stars[2 stars]
Fish oil and its omega-3 fatty acids have positive metabolic effects and are especially effective for lowering high triglyceride levels in people with metabolic syndrome.
Probiotics
= 6.5 billion colony forming units (CFUs) daily2 stars[2 stars]
Early research indicates probiotics have likely, though small, benefits on metabolic and cardiovascular health.
Vitamin D
3 to 4,000 IU of vitamin D3 daily2 stars[2 stars]
Vitamin D deficiency increases the risk of metabolic disorders.
Calcium
Refer to label instructions 1 star[1 star]
One study found that supplementing with calcium improved insulin sensitivity in people with hypertension.
Vitamin E
Refer to label instructions 1 star[1 star]
Vitamin E supplements, particularly tocotrienols, have been found to be beneficial in treating the conditions that make up metabolic syndrome.
Zinc
15 to 50 mg daily1 star[1 star]
Zinc is important for metabolic health, but there are risks associated with both too little and too much zinc.
  • 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 some in 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.
