OPC grape seed extract – definition, efficacy, intake and experiences

More and more people are losing confidence in conventional medicine and conventional forms of therapy or medication. At the same time, however, the demand for alternatives such as natural dietary supplements and natural history healing methods is steadily increasing. In this context, more and more use is made for grape seed extract. This paper explains how it works, how it is applied and what scientific evidence is available in this regard.

What is OPC?

OPC (abbreviation for oligomeric proanthocyanidins or oligomeric procyanidins) is biochemically one of the flavonoids. These, in turn, are so-called phytonutrients that have beneficial effects on health. Those who do not really deal with this topic will quickly come to the conclusion that this plant material occurs mainly in the nuclei of the grape. However, proanthocyanidins are also found in other spices and foods. For example, in apples, cinnamon, cocoa, nuts and, of course, in grape seeds, this plant material occurs, but in different proportions.

In wine, this substance is mainly found in the outer parts of the plant, such as In the bark or in the grape peel, but also in the core casings and in the seeds themselves. However, the concentration varies greatly, with much more in red wine than in white wine. Many experts believe polyphenols are among the most essential vital substances the human body needs. In addition, there are ongoing studies to prove that polyphenols increase antioxidant levels in the blood and thus counteract cell damage from free radicals. As a dietary supplement, the plant substance is mainly highly dosed in capsule form, which contains a high proportion of antioxidants.

Is there already scientific evidence for the efficacy of OPC?

Researchers are now continuously providing scientific evidence of the health benefits of grape seed extract:

  • The plant substance and its antioxidant effects can prevent or stop diseases. For example, within a Japanese study in 2013, it was shown that by taking oligomeric procyanidins, it can promote the prevention of atherosclerosis. (Source: https://www.ncbi.nlm.nih.gov/pubmed/23176379)
  • However, oligomeric procyanidins also have a positive effect on cholesterol levels. People who have high cholesterol were able to lower their levels through grape extract intake. That's proved by an American study by Georgetown University. (Source: https://www.ncbi.nlm.nih.gov/pubmed/11508317)
  • In people with obesity or obesity, both insulin resistance and inflammatory levels have been improved by taking it. This effect was evimented by studies by the Iranian University of Tabriz. This positive effect has shown that the capsules preserve the health of the body's cells. (Source: https://www.ncbi.nlm.nih.gov/pubmed/23506314)
  • By taking the plant substance, people with chronic high blood pressure or hypertensive heart disease can also be helped. A multi-week American study showed that by administering vitamins and OPC capsules, blood flow was improved. As a result, high blood pressure has also been significantly reduced. The effect is best developed by taking the capsules with a drink. These findings clearly show that OPC capsules are not only good for the skin, but also for the cells and the heart.

  • The secondary plant substance can also have a beneficial effect on diabetes. Indian researchers have found that taking OPC capsules produces a similar effect to the conventional drug metformin. In theory, therefore, the plant substance is also able to reduce too high blood glucose levels and keep insulin levels constant in the cells. (Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3972396/)
  • People suffering from Alzheimer's disease gradually lose their independence and can no longer do their daily life independently. An American study showed that the degenerative process can be stopped in the cells of the brain, thereby preventing the deposition of beaamyloid (a specific protein). Taking OPC capsules could not only prevent the disease, but also help people who have already fallen ill regain more memory. (Source: http://www.plantphysiol.org/content/154/2/453)

How should the extract of grape seeds be taken?

As a rule, the recommended daily dose of the extract of the grape is about 150 to 300 mg for adults. In most cases, food supplements in the form of tablets or capsules are used.

If you want to play it safe, you should definitely stick to the recommended daily dose. If the extract is used as a therapy measure, which requires a significantly higher dose, then consultation with a doctor should always be kept. If the plant substance is used therapeutically, a daily dose of 400 mg and more is allowed. Otherwise, 1 to 2 mg per kilogram of body weight can be taken for prevention. In a person weighing 80 kg, a dose of between 80 and 160 mg per day is recommended.

The plant extract may be able to amplify the blood thinning effect, although this effect has not been studied until now.

The secondary plant substance is 100% natural and free of side effects when paying attention to the recommended daily dose. It is important to take the capsules or tablets regularly and together with other vitamins. The reason for this is that the effect of the vitamins is enhanced by the extract of the grape and vice versa. In other words, for example, vitamin C is taken at the same time, thus enhancing the secondary plant substance and this in turn enhances the effect of the C vitamin.

In order for the effect to develop optimally, it is advisable to take the capsules on an empty stomach. With a little liquid, the capsules are consumed about 30 minutes before the first meal. If you have problems taking tablets or capsules on an empty stomach, you can also take them together with a meal.
