Health Notes

Proanthocyanidins

Proanthocyanidins
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Sunburn
Dose: 1.1 to 1.66 mg per 2.2 lbs (1 kg) of body weight per day during periods of high sun exposure
Proanthocyanidins are a group of flavonoids found in pine bark, grape seed, and other plant sources that may increase the amount of ultraviolet rays necessary to cause sunburn.(more)
Retinopathy
Dose: 150 mg daily
Proanthocyanidins, a group of flavonoids found in pine bark, grape seed, and other plant sources, may help slow the progression of diabetic retinopathy.(more)
Pancreatic Insufficiency
Dose: Refer to label instructions
In a preliminary report, three patients with chronic pancreatitis who were treated with grape seed extract saw reduced frequency and intensity of abdominal pain.(more)
Retinopathy
Dose: 150 mg daily
Proanthocyanidins, a group of flavonoids found in pine bark, grape seed, and other plant sources, may help slow the progression of diabetic retinopathy.(more)
Chronic Venous Insufficiency
Dose: 50 to 100 mg two to three times daily
Proanthocyanidins, a group of flavonoids, have been shown to strengthen capillaries in double-blind research.(more)
Capillary Fragility
Dose: 150 mg daily
Proanthocyanidins, flavonoids extracted from grape seeds, have been shown to increase capillary strength in people with hypertension and diabetes.(more)
Varicose Veins
Dose: Refer to label instructions
One trial found that supplementing with proanthocyanidins improved the function of leg veins in people with widespread varicose veins.(more)
Sunburn
Dose: 1.1 to 1.66 mg per 2.2 lbs (1 kg) of body weight per day during periods of high sun exposure

Trials have tested combinations of several antioxidants. One preliminary study found that a daily combination of beta-carotene (6 mg), lycopene (6 mg), vitamin E (15 IU), and selenium for seven weeks protected against ultraviolet light.1 However, a double-blind trial of a combination of smaller amounts of several carotenoids, vitamins C and E, selenium, and proanthocyanidins did not find significant UV protection compared with placebo.2 Similarly, in a controlled trial, a combination of selenium, copper, and vitamins was found to be ineffective.3

Proanthocyanidins (OPCs) are a group of flavonoids found in pine bark, grape seed, and other plant sources. In a preliminary trial, volunteers were supplemented with Pycnogenol, an extract of French maritime pine bark rich in OPCs, in the amount of 1.1 mg per 2.2 pounds of body weight per day for the first four weeks, and 1.66 mg per 2.2 pounds of body weight per day for the next four weeks.4 Compared with ultraviolet sensitivity before supplementation, the lower amount of Pycnogenol was found to significantly increase the amount of ultraviolet rays necessary to cause sunburn, and the higher amount was significantly more effective than the lower amount.

Retinopathy
Dose: 150 mg daily

Proanthocyanidins (OPCs), a group of flavonoids found in pine bark, grape seed, and other plant sources have been reported in preliminary French trials to help limit the progression of retinopathy.1, 2 In one controlled trial, 60% of people with diabetes taking 150 mg per day of OPCs from grape seed extract had no progression of retinopathy compared to 47% of those taking a placebo.3

Pancreatic Insufficiency
Dose: Refer to label instructions

In a preliminary report, three patients with chronic pancreatitis were treated with grape seed extract in the amount of 100 mg 2-3 times per day. The frequency and intensity of abdominal pain was reduced in all three patients, and there was a resolution of vomiting in one patient.1

Chronic Venous Insufficiency
Dose: 50 to 100 mg two to three times daily

Proanthocyanidins (OPCs), a group of flavonoids found in pine bark, grape seed, grape skin, bilberry, cranberry, black currant, green tea, black tea, and other plants, have also been shown to strengthen capillaries in double-blind research using as little as two 50 mg tablets per day.1 In a double-blind trial using a total of 150 mg OPCs per day, French researchers reported reduced symptoms for women with CVI.2 In another French double-blind trial, supplementation with 100 mg taken three times per day resulted in benefits within four weeks.3

Capillary Fragility
Dose: 150 mg daily

Compounds called flavonoids may help strengthen weakened capillaries. In test tube and animal studies, they have been shown to protect collagen, one of the most important components of capillary walls.1, 2 A preliminary study found that proanthocyanidins (flavonoids extracted from grape seeds), 150 mg per day, increased capillary strength in people with hypertension and/or diabetes.3 A double-blind trial found a combination of two flavonoids (900 mg per day of diosmin and 100 mg per day hesperidin) for six weeks reduced symptoms of capillary fragility.4 Use of vitamin C with flavonoids, particularly quercetin, rutin, and hesperidin, is sometimes recommended for capillary fragility.5 Doctors often recommend 400 mg of rutin or quercetin three times per day or 1 gram of citrus flavonoids three times per day.

Varicose Veins
Dose: Refer to label instructions

A small, preliminary trial found that supplementation with 150 mg of proanthocyanidins per day improved the function of leg veins after a single application in people with widespread varicose veins.1 Double-blind trials are needed to determine whether extended use of proanthocyanidins can substantially improve this condition.
