Pine bark extract is a substance extracted from the bark of pine trees.Pine bark from the trees is collected and smoothed out.It contains large amounts of compounds called OPCs(proanthocyanidins oligomers).OPCs have been found in many plants since they were isolated from peanut shells by French scientist Dr. Jack Mescali in 1947.A large number of studies have shown that OPCs is an effective antioxidant, and it is non-toxic, non-mutagenic, non-carcinogenic and has no side effects.Very safe to use.Pine bark has proved to be a new source of OPCs, and OPCs extracted from pine bark are not different in quality or function, except for some slight differences in appearance.

The antioxidant capacity of pine bark extracts comes from procyanidins (procyanidins oligomers)(OPCs), which are 20 times more potent than vitamin C and 50 times more potent than vitamin E.OPCs is a well-known antioxidant that can effectively suppress free radicals, which play an important role in degenerative diseases, cardiovascular diseases, blurred vision, sunburn and premature aging.
Pine bark extract is also a good antioxidant nutrient.It can be used alone or in conjunction with the grape factor.In the use of the process, the role of common use will be better.Nutritionists in nutritional food manufacturing in the United States use a lot of modern high-tech means, from many ordinary food they put effective antioxidants extracted, the use of these nutrients extract, nursing for chronic diseases can have very good effect, is both effective and safe, and the improvement of the whole body system can help the patients.

So,what are the functions of Pine Bark Extract?
1. Treat atherosclerosis
The oxidant LDL has been shown to play an important role in causing atherosclerosis.Due to its excellent antioxidant properties, OPCs can prevent or repair atherosclerosis by eliminating free radicals as well as collagensin and elastase damage to arterial walls.Animal studies have shown that OPCs can slow or repair atherosclerosis.
2. Venous insufficiency (varicose veins)
Varicose veins occur when blood is concentrated in the legs and can cause pain, heaviness, edema, fatigue, and venous extravasation.By strengthening capillary strength and reducing capillary permeability, OPCs can reduce pain and edema caused by venous insufficiency.For the same reason, OPCs is recommended as an excellent treatment for hemorrhoids.There are indications that OPCs may also be effective in treating injuries and post-operative edema.OPCs can speed up the removal of edema by repairing damaged blood and lymph vessels that drain fluid.
A double-blind controlled agent test involving 92 people showed that ingestion of 100mgOPCs three times a day significantly improved major symptoms including heaviness, edema, and foot discomfort.Over a period of one month, 75% of patients receiving OPCs experienced sufficient improvement in their symptoms.Another controlled agent test, involving 364 individuals, also showed that the OPCs group had significantly better results than the placebo group.
3. Retinopathy/improved vision
OPCs strengthen capillaries and reduce permeability in patients suffering from stroke and retinopathy.OPCs has been shown to improve retinopathy due to diabetes, atherosclerosis, inflammation and aging.It has also been reported that OPCs can speed up the visual recovery after bright light and improve the visual acuity of patients with visual fatigue caused by long time use of computer.
A 6-week controlled (but not blind) study evaluated the ability of grape skin (seed)OPCs to improve nocturnal vision in normal subjects.In this trial, 100 healthy volunteers who received 200mgOPCs a day showed significant increases in nighttime vision and strong flash recovery compared with the control group who did not receive the drug.
