I take insulin (Humalog) for diabetes. Are there supplements which could affect my blood sugar levels, and how much insulin I need to take?
A number of supplements may affect blood sugar levels typically reducing them and require you to, therefore, reduce your dose of insulin (sold as Humalog, Humulin, Iletin, Lantus, Levemir, Novolin, Novolog, Velosulin, etc.).
The supplements which may have this effect include aloe, chromium, ginseng, and CoQ10, and there is weaker evidence for about 30 others. See the list of these supplements and get more information in the Insulin article, which is part of the extensive Drug Interactions section of our website (where you can also look up supplement interactions for other drugs you may be taking).
