Dosage and Administration:

In August 2004, the American Heart Association (AHA) published a scientific advisory warning that little evidence was found for the effectiveness of antioxidant vitamin supplements to prevent cardiovascular disease. While acknowledging the benefits of antioxidants, the scientists who prepared the AHA recommendation advise getting natural antioxidants from foods rather than from supplements. Additionally, some evidence from animal studies suggests that very high doses of antioxidants such as those in grape seed extract may actually increase damage from oxidation. Therefore, doses of supplemental antioxidants should be no higher than recommended by the manufacturer of the product.
Oral grape seed extract is available as capsules or tablets usually containing 50 mg or 100 mg. While recommended doses are different for specific uses, a common recommendation for maintaining general health is 50 mg to 200 mg per day. Some manufacturers suggest that doses should be higher for older individuals and some animal studies have found few side effects from extremely high doses. Because the effects of high doses on humans have not been documented, however, dosing should be limited to no more that recommended on the package of the product being taken.
Grape seed oil is available in bulk for use in preparing and cooking foods. No limits are placed on its use, but it does contain about 120 calories per tablespoon ?comparable to other cooking oils. If it replaces normal use of other oils, grape seed oil should not present any problems. Adding it to the diet or taking excessive amounts of it may lead to obesity, however.

Summary: Oral grape seed extract is most used for strengthening blood vessel to treat conditions such as chronic venous insufficiency and retinopathy. As an antioxidant, it may also have effects against cancer, heart disease, viruses, and cell damage caused by toxic chemicals. Topically, grape seed extract may protect against dental cavities and promote wound healing. Oil pressed from grape seeds is a supplemental source of essential fatty acids.

Risks: Pregnant and breast-feeding women should not take grape seed extract, due to limited information about its potential effects on developing babies or infants.

Side Effects: Cough, headache, and nausea are among the side effects reported by participants in clinical studies of grape seed extract.
