What is Grape Seed Extract?

What is grape seed extract and what are the benefits of usage of grape seed products?

Grapes have been an essential part of human culture and cuisine for thousands of years. It has been known since the ancient times that wine consumption is good for the health. The effects of grape seed were unknown until the 20th century, the Nobel-prize awarded scientist, Dr Albert Szentgyörgyi was the first who mentioned the beneficial effects of grape seed to the human body in 1936. He concluded that grape seed contains the most natural antioxidants, it has positive effects on blood circulation and it contributes to the protection of brain and nervous system.

Grape seed has antioxidant, antiallergenic, antihistamine, anti-inflammatory and immune boosting properties and it can be instrumental in helping the body fight viruses, allergens, and carcinogens. It contains health-supporting ingredients, such as vitamin E, polyphenols, linoleic acid, OPCs, protein, carbohydrate, sodium, magnesium, calcium, iron, potassium, zinc, manganese, boron, copper and numerous trace elements.

How Does Grape Seed Extract Work?

Polyphenols are known for their activity as highly influential antioxidants. French scientific studies have shown that the antioxidant power of polyphenols is 20 times more powerful than vitamin E, and 50 times greater than vitamin C. Polyphenols are involved in defence against ultraviolet radiation. Studies suggest that long-term consumption of diets rich in polyphenols protect against the development of cancers, cardiovascular diseases, diabetes, osteoporosis and neurodegenerative diseases.

Oligomeric proanthocyanins (OPCs) have been studied for a variety of health conditions, they are most well known for their antioxidant activity. Polyphenols and OCPs help protect the blood vessels from damage, which help prevent high blood pressure and it also helps improve blood circulation by strengthening capillaries, arteries and veins.

Antioxidants In Grape Seed Extract

Antioxidants are substances that prevent and control numerous disease by safeguarding cells against the oxygen molecules called free radicals, which are harmful compounds in the body that damage DNA and even cause cell death. Free radicals can be caused by both internal bodily processes and external factors like sun damage, pollution, cigarette smoke and even stress. It has a significant influence on ageing, as well as on the development of several health problems, including heart disease, atherosclerosis (hardening of the arteries) and cancer. A balance between free radicals and antioxidants is necessary for proper physiological function. If free radicals overwhelm the ability of the body to regulate them, a phenomenon called oxidative stress occurs. Application of external source of antioxidants can assist in coping this oxidative stress.

Animal studies suggest grape seed extract may reverse hippocampal dysfunction in the brain by reducing oxidative stress. Grape seed extract may even be useful as a preventative or therapeutic agent in Alzheimer’s disease. The extract effectively penetrates cell membranes throughout the body with its antioxidant properties, it can even cross into the brain to protect brain cells from free-radical damage. The extract improves mental alertness, fights mental fog, and may help in preventing senility and other age-related cognitive complications.

What Is Grape Seed Extract?

Grape seed extract is the industrial derivative of whole grape seeds that is rich in flavonoids, phenolic procyanadins (oligomeric procyanidins or OPC), linoleic acid and vitamin E. When it comes to commercial use and extraction, a chemical named polyphenols is preferred because it contains antioxidant features in vitro.

In order to answer the question ‘what is grape seed extract?,’ people have to know that it is made up of a complex mixture of flavonoids, containing 73.32 to 77.63 percent oligomeric procyanidins and proanthocyanidins or polymeric flavan 3-01s and 5.5 percent or less monomeric flavan 3-01s (in dry form). Proanthocyanidins are present in numerous foods consisting of fruits like cherries, plums and apples, tea, beans, wine, fruit juices and chocolate.

Grape Seed Extract Composition

To get brief information about the composition of extract, and understanding grape seed extract vitamin benefits, nutritionists have listed everything as per their proportion or quantity.

  • Polymers of catechin (subsets of flavonoids), proanthocyanidins (procyanidins) molecules having 74 to 78 percent weight that sometimes go up to 81 percent of grape seed extract.
  • Free flavonol esters like catechin (Green Tea Catechins) and epicatechin at 6% or less.
  • Certain procyanidins molecules like Procyanidin C1 (1.7%), B1 (5.3%) and B2 (3.1%) – having different combinations of catechin couplets.
