Answered by: Conrad Richter
Question from: Sandra
Posted on: March 27, 2001

Can you please tell me about these: grape seed, pine bark and red wine extract? It also has on the paper, "Isotonix OPC-3."

Can you tell me about this? Someone said I should take this but I can’t find anything on it.

We do not comment on proprietary products made by other manufacturers. You should contact the company that makes the product "Isotonix" product for specific information about their product.

We can tell you that "OPC" stands for a group of plant bioflavonoids called oligomeric proanthocyanidins. These are commonly found in herbs such as grape seed, pine bark and red wine. They are antioxidants that are claimed to neutralize free radicals which can damage cell membranes. Products containing OPCs are claimed to help everything from Crohn’s Disease to Multiple Sclerosis.
