Part of the plant used: seed
Grape vine has been cultivated since the dawn of time. Today, it is found in all temperate climates around the globe. Grape seed oil is rich in essential fatty acids and vitamin E.
Oligo-proanthocyanidins (OPC) are potent antioxidant compounds. OPCs are found in the grape seed's envelope and are responsible for the pharmacological effects. Several standardized extract supplements are currently available on the market.
Used doses: 150 mg to 475 mg of OPC-standardized (80%) grape seed extract daily.
There is insufficient reliable information to conclude that grape seed extract is effective in any other indication.
In 2004, Canada adopted new regulations that control the manufacturing, packaging, labeling and importing of natural health products. The new regulations also include an adverse reaction reporting system. Products that conform to the regulation's criteria are identified with a natural product number (NPN) and can be legally sold in Canada. This number indicates that the product meets specific criteria for safety and purity, not that it is effective for any indication.
Medicinal plant contents vary naturally from plant to plant - just as fruits from the same package may vary in taste and texture. There is no standard to measure the active content of each plant. Thus, efficacy of natural products should be expected to vary from brand to brand as well as from bottle to bottle of the same brand.
