Grape seed components may be active against HIV by inhibiting virus expression and replication.
Preliminary research shows that grape seed extract may have other possible anti-disease properties, as follows:
1. In wound healing -- grape seed proanthocyanidins induced vascular endothelial growth factor and accelerated healing of injured skin in mice;
2. In tooth decay --
Seed phenolics may inhibit oral sugar metabolism and retard growth of certain bacteria causing dental caries;
3. Grape Seed Extract in osteoporosis -- grape seed extracts enhanced bone density and strength in experimental animals;
4. In skin cancer --
Grape seed proanthocyanidins decreased tumor numbers and reduced the malignancy of papillomas;
5. In ultraviolet damage to skin --
Dietary proanthocyanidins may protect against carcinogenesis and provide supplementation for sunscreen protection.
Grape Seed Extract (GSE) is a supplement derived from grape seeds which is a vessel for proanthocyanidin/procyanidin molecules (the two terms are used interchangeably). Procyanidins in GSE are chains of catechin molecules, which are the polyphenolic compounds found in teas and collectively referred to as Green Tea Catechins; Specifically, procyanidins appear to be chains of (+)-catechin rather than gallocatechin or EGCG and may be absorbed in their chained forms. Despite being from grapes, GSE shares no structural similarity with Resveratrol (the chains of resveratrol are known as stilbenes, and are found in plants such as Japanese Knotweed)
Procyanidins are found in a wide variety of foods, and the main human dietary sources appear to be fruits (apples, grapes, berries, plums), beverages (tea, cocoa, Wine), cereals grains (sorghum, barley), nuts, and chocolate via the Cocoa Extract and the estimated daily intake is approximately 53.7mg. Procyanidins in general are also the active ingredients of the Maritime French Pine Bark Extract supplement known as Pycnogenol. Different sources of procyanidins may have different effects on the body, depending on how the catechin chains are formed and bound to each other.
