Immunity of living organisms is the key for their existence and survival. Optimal Immune system for the human body is vital for a younger and healthier life. An optimal Immune system reduces the chances of various diseases and slow down the ageing process.

The health-beneficial effects of grape plant has been recognized for thousands of years. By tradition, grapes are made in grape juice, fermented into wine, and dried for raisins.  The grape vines and leaves were used to make tinctures and healing ointments. The human empirical knowledge accumulated throughout history includes the use of grapes and the plant parts in treating various diseases and conditions, like skin infections, sore throat, cholera, indigestion and even cancer.

Antioxidant supplement is new knowledge that human beings just learned in science in the last few decades for healthy immune system. Grape seed extract contains natural products as powerful antioxidants, mainly flavonoids of the flavan-3-ol class that also are called as oligomeric proanthocyandins (OPC).

Multifunctional Health Benefits of Grape Seed Extract

Grape seeds were not traditionally recognized for their nutritional and therapeutic benefits, and were treated as waste material in the vinery industry. Grape seed extract was not discovered by human until about 1970, and have been found since then to contain a variety of natural products of rich health benefits, in addition to those as antioxidants. Scientific studies have been published for antiallergenic, antihistamine, anti-inflammatory, immune boosting activities of grape seed extract as a whole. It may have benefits in helping the body fight viruses, allergens and carcinogens. Grape seed extract natural products also play an important role in the stabilization of collagen and maintenance of elastin, two critical proteins in connective tissue that support joints, organs, muscle and blood vessels.

Grape seed extract helps the overall immune system of the human to act cooperatively in a harmony way for health and longevity.

Damages of Immune System by Free Radicals

There are many damages that free radical damages can do on our human body. Many damages, once done, can be quickly fixed by our body itself due to the immunity – the defense system of the body. A damaged DNA, if not fixed, may lead to a tumor or cancer cell. The chance for a damaged DNA molecule to form tumor or cancer cell is extremely low, because our immune system can detect and fix.

However, free radical can also damage the immune system directly in many ways. For example, the damage may disable the monitoring and repairing functional enzymes, so that a damaged DNA molecule, without being fixed, may continue to replicate and transcript to form cancer cells.

Aging process is largely caused by weakening immune system caused by damages of free radicals. The damages of free radicals on other parts are insignificant than the damages on the immune system.

Grape seed extract as the powerful antioxidants do many things good to our body. But the most important thing is to protect our immune system as a free radical scavenger to reduce possible free radical damages on the immune system. Grape seed extract contains potent antioxidants, much more powerful than vitamin C, E and beta-carotene together, making it the champion among all antioxidants. Antioxidants help our bodies control the levels of free radicals that attack our immune system. Scientific studies are conducted to explore the possibility that grape seed extract may reduce the chances for cancer, heart disease and other dangerous conditions to be initiated and to be developed.
