Beta-glucan is a fiber-type complex sugar (polysaccharide) derived from the cell wall of baker’s yeast, oat and barley fiber, and many medicinal mushrooms, such as maitake. In their natural states, yeast and mushrooms contain a mixture of beta-1,3-glucan and beta-1,6-glucan. Oats and barley contain a mixture of beta-1,3-glucan and beta-1,4-glucan. In addition to purified beta-1,3-glucan from these sources, you may see products listed as beta-1,3/1,6-glucan in the case of yeast-derived products and as beta-1,3/1,4-glucan when derived from oats. Similar (if not identical) properties have been shown for beta-glucan-rich extracts and purified beta-glucan derived from oats, baker’s yeast, and mushrooms.
- 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.
This supplement has been used in connection with the following health conditions:
|2,900 to 15,000 mg daily||[3 stars] |
Beta-glucan is a type of soluble fiber that has been shown to lower total and LDL (“bad”) cholesterol and raise HDL (“good”) cholesterol.
(Inulin, Pectin, Resistant Starch)
|10 grams total fermentable fiber daily||[2 stars] |
In a study of people with cirrhosis, supplementing with fermentable fiber (containing equal parts of beta-glucan, inulin, pectin, and resistant starch) improved liver and brain function.
|Refer to label instructions||[1 star] |
Beta-glucan activates white blood cells, which in turn can recognize and kill tumor cells, correct oxidative damage, and speed up recovery of damaged tissue.
