CONCLUSION: We conclude that β -glucan is a safe and effective supplement for lowering cholesterol and blood sugar. While it shows promise for strengthening the immune system, there is insufficient evidence for us to recommend its use for this indication. If you do elect to try it, please discuss your decision with your doctor, and observe carefully for any changes to your health.
