Why was this study done?
Beta-glucans are well-known immune-stimulating polysaccharides found in large amounts in certain yeasts, mushrooms, and other foods. Beta-glucans, though, may not be the only immune stimulating molecule in these foods. This study was designed to test beta-glucan alone versus a mixture of yeast, mushrooms, and ginseng and compare their effects on immune cells.
What did the study find?
This study found that a combination (called PX3) was more effective than beta glucan alone at stimulating the immune system (including cytokine production and lymphocyte proliferation).
