As part of our Food for Thought section, we will begin profiling a nutritional supplement every month.
Research indicates that some vitamins, herbs and supplements may be beneficial to diabetes control. Always check with your diabetes care team before adding one to your regimen, as some may be unsafe for you or could interact with your other medications.
What follows is a summary of research explaining the benefits of some nutritional supplements, as well as their recommended daily dosages.
- Alpha-lipoic acid (lipoic acid): May help to relieve nerve pain
- Benflotiamine: May help to prevent smallblood-vessel problems
- Chromium: May lower A1C levels
- Cinnamon: May improve blood glucose levels
- Fenugreek: May improve blood glucose control
- Fish oil: May benefit heart health
- Ginseng (American and Asian): Was thought to improve blood glucose control but recent studies show little if any effect
- Magnesium: May improve insulin sensitivity
- Nopal (prickly pear): May increase insulin sensitivity
- Pycnogenol (pine bark extract): May improve blood vessel and retinal health
- Psyllium: May slow glucose absorption
- Quercetin: May offer antioxidant protection
- Vitamin C: May lower heart disease risk
- Vitamin E: May lower A1C levels
