Research concerning resveratrol and diabetes is still being conducted. A recent business business transaction involved a drug company purchasing a supplement manufacturer in the US. As a team, they hope to market a diabetes drug based on trans-resveratrol, the biologically active form of the nutrient. It will be several years before the drug is available.
In the meantime, there are dietary supplements containing it, but if you plan to buy one, you need to do some comparative shopping. The supplements can be very expensive and they aren’t likely to be of any benefit. Trans-resveratrol has very low bio-availability, meaning that it is difficult for the human body to use.
If taken in the form of an uncoated tablet or a liquid, blood levels of the nutrient are not greatly increased. Researchers have conducted several different studies to try to determine exactly how much makes it to the bloodstream. Knowing this will help them establish an appropriate dosage for lowering blood sugar.
It was found that drinking red wine along with food caused a greater increase in resveratrol blood levels than drinking wine alone. This indicates that stomach acid is the problem. An enteric coating that protects the nutrient from stomach acid is the solution.
If you are interested in resveratrol and diabetes, you might also be interested to know that it is not the only natural supplement that effectively lowers blood sugar levels. Pharmacy companies have not been interested in these supplements, and they are not highly publicized in the US.
Making specific recommendations for herbal and other natural remedies is a big problem in the US. Manufacturers are severely limited as to what they can put on the bottle.
The resveratrol and diabetes studies are relatively new, but the substance was identified and isolated in a medicinal plant in 1940. The plant had been used by traditional healers to treat those who suffered from high blood pressure or rapid heartbeat. Other plants were used traditionally to lower blood sugar. Many of them are still used today in some areas of the world.
Banaba, for example, a plant native to Southern Asia, has been used to treat diabetes and to assist in weight loss. Bitter melon, native to the Philippines, is still used for controlling blood sugar, particularly among the poor. Green tea, because of its antioxidant activity, is often recommended to help prevent complications that may arise from diabetes.
So, as you learn about resveratrol and diabetes, you might also want to learn about some of these other plant extracts. They are available in some of the better health supplements, designed specifically for people who suffer from the disease.
As a preventive measure, perhaps for those who have a family history of type II diabetes, 20-50mg of trans-resveratrol in a coated tablet is sufficient. For the best value, look for one that contains a variety of different nutrients, including your basic daily vitamins and minerals.
My only concern about the ongoing resveratrol and diabetes research is that the pharmaceutical companies are likely to use a synthetic version. Synthetics are never as effective as the “real thing”.
