Grapeseed oil also contains 0.8 to 1.5% unsaponifiables rich in phenols (tocopherols) and steroids (campesterol, beta-sitosterol, stigmasterol).[9] Grapeseed oil contains small amounts of vitamin E, but safflower oil, cottonseed oil, or rice bran oil contain greater amounts.[10] Grapeseed oil is high in polyunsaturated and low in saturated fat.

Chardonnay grape seed oil is derived from the seeds of the Chardonnay grape by using the cold-pressed method. Grape seeds have a high content of flavonoids named proanthocyanidins which is essential for the maintenance of brain health due to the presence of antioxidants as well as collagen preserving effects. The presence of proanthocyanidins slows down the beginning of lipid peroxidation. Its traditional uses are known from ancient times and are usually used for its seed.
The extracts of seed are loaded with various health benefits
Heart health

The seeds of the Chardonnay grape hinder the low-density lipid oxidation. It also prevents the chances of heart problems by maintaining the level of cholesterol under control. It has a positive effect on arteries that reduce blood pressure by maintaining heart health.

Prevent cancer

Grapeseed oil helps to prevent cancer and prevents cancer proliferation. It is helpful for patients with breast and prostate cancer. These small seeds help to maintain a healthy life.

Brain health

The seeds of the Chardonnay grape help to lower the oxidative stress on the brain, nerves, eyes, and brain by preventing the chances of Parkinson’s disease, Alzheimer’s disease, and neurodegenerative problems.

Treat obesity

This oil controls the level of glucose and the production of insulin that helps to counteract obesity. The antioxidants help to keep the weight in proper condition. The problems in the liver help to treat weight gain and digestive problems.

Skin health

Chardonnay grape seed oil helps to repair skin health and provides blemish-free skin. It acts as anti-inflammatory, anti-histamine, and anti-allergic properties. It prevents damage to the system.
Protects against free radicals
The antioxidants found in grapeseed oil, such as vitamin C, vitamin E, and proanthocyanidin (phew), can help to prevent—and undo—pollution- and UV-induced free radical damage to the skin, says Dr. Shainhouse. The result? Skin that’s smooth and firm—and better protected against more serious issues too, such as skin cancer. (Remember: Free radicals are unstable molecules that can wreak havoc on your body’s cells.)
Grapeseed oil is a good source of Vitamin E

After the intense chemical extraction process, most of the good properties are actually filtered out. The only nutrient left in any significant amount is Vitamin E. One tablespoon of grapeseed oil contains 9 mg of Vitamin E, which is 19% of the Recommended Daily Allowance. In fact, grapeseed oil contains about twice as much Vitamin E as olive oil. Vitamin E is an antioxidant that helps prevent cell damage in your body and strengthens your immune system.

Grapeseed oil has no cholesterol and very little saturated fat

Yes, grapeseed oil is rich in cholesterol-lowering polyunsaturated fats. 1 tablespoon of grapeseed oil contains 14 grams of fat, about 10 percent of which is saturated fat, 16 percent monounsaturated, and 70 percent polyunsaturated.

Grapeseed oil has a high smoke point

It’s true. The Academy of Nutrition and Dietetics notes that grapeseed oil has a moderately high smoking point which makes it ideal for frying and sauteing. “Grapeseed oil has a mild nutty taste so the flavor of the food you are cooking with it shines through. For Indian food, you can make your dry vegetable preparations with grapeseed oil. It also has terrific emulsifying properties, which makes it an excellent oil for salad dressings.

Grapeseed oil has the highest concentration of polyunsaturated fats, so it’s good for your heart

Yes, grape seed oil is very high in polyunsaturated fats. However, there are two main kinds of polyunsaturated fats: Omega-3s and Omega-6s. To maintain optimal health, the balance of different kinds of polyunsaturated fats is important. And as it turns out, grapeseed oil contains mostly Omega-6 fatty acids. There is also not enough scientific backing to prove that grapeseed oil is heart-healthy.

Grapeseed oil is beneficial for hair and skin

Grapeseed oil has been championed as a wonderful addition to any beauty regimen and for good reason. Grapeseed oil helps remove tan, moisturize the skin, give you that glow you’ve always wanted and even lighten the effects on age spots. Many skincare creams contain grapeseed oil as well”. It contains 73% of linoleic acid which may be beneficial in the treatment of acne, allergic reactions, and dry and itchy skin. Grapeseed oil is free from synthetic ingredients and loaded with moisturizing fatty acids, so there seems to be nothing wrong with applying it topically.
Key Grapeseed Oil Benefits for Skin
Manages acne breakouts

One of the top grapeseed oil benefits is that it’s high in linoleic acid, an omega-6 fatty acid that can help control acne by decreasing clogged pores. Acne-prone skin has been found to be deficient in linoleic acid – so adding more of this fatty acid to your skin via grapeseed oil can help to cut back on breakouts. It also rates as a very low 1 on the comedogenic scale, making it ideal for most skin types.
Lightens acne scars

Thanks to its vitamin E and linoleic acid content, grapeseed oil lightens skin discolorations like acne scars and sunspots. Studies have shown that it can help speed up the healing process and decrease the formation of keloid scars: raised, enlarged scarring commonly caused by severe burns, cuts, or acne.
Protects against free radicals

Grapeseed oil is rich in many other superior compounds: beta-carotene, vitamins D, C, E, and polyphenols. These compounds have powerful antioxidant abilities, which can prevent your skin from absorbing the full damage of UV rays or other environmental aggressors.
Moisturizes and balances the skin

Grapeseed oil is chock full of vitamin E, which is excellent for locking moisture into the skin. This vitamin plays an essential role in softening and hydrating the skin’s outer layer. Meanwhile, it’s superstar fatty acid components fortify the skin barrier while smoothing and balancing the skin.
Absorbs easily

Grapeseed oil absorbs easily, delivering intense moisture without leaving skin feeling oily or greasy. Since this lightweight oil penetrates so well, it’s also a superstar ingredient for hair. When applied to your hair, grapeseed oil adds moisture, strength, and shine.
Minimizes fine lines and wrinkles

Thanks to the polyphenols found in grapeseed oil, these gems help combat premature aging and wrinkles. Along with fatty acids, grapeseed polyphenols also help to mitigate signs of premature aging while boosting circulation. This oil also has natural astringent properties, making the skin look tighter and more youthful.
Antimicrobial

Yet another one of the major grapeseed oil benefits is that its antimicrobial properties make it an ideal sidekick in your fight against breakouts. Its mildly astringent properties help reduce inflammation and control the inflammatory response of the skin. The oil may be useful for inflammatory conditions such as rosacea, eczema, or those who simply have sensitive skin.
Evens skin tone

As we mentioned, one of the grapeseed oil benefits is that it contains a powerful antioxidant ingredient called proanthocyanidin. This antioxidant works on making the skin tone more even and enhances brightness in the complexion. This oil is known to improve symptoms of melasma and hyperpigmentation when taken orally.
Supports Collagen

Thanks to its vitamin E content, grapeseed oil benefits and assists in the production of collagen and improves skin tone. This mighty vitamin, along with proanthocyanidins, increases the restoration rate of collagen meaning firmer, more youthful-looking skin.
Antifungal

Finally, grapeseed oil also has natural antifungal properties. That makes it a fantastic carrier oil for nail treatments. You’ll find grapeseed oil benefits in our Nail & Cuticle Oil. This nourishing oil also features vitamin E and jojoba to strengthen brittle nails and deeply moisturize. Blue tansy helps to calm redness and inflammation from fungus or hangnails.

What are the benefits of grape seed extract?

The grape seed extract is an industrial derivative of grape seeds. It is rich in antioxidants and oligomeric proanthocyanidin complexes and has been linked to a wide range of possible health benefits.

These include the treatment of conditions such as high cholesterol, atherosclerosis, macular degeneration, poor circulation, and nerve damage.

Many of these health claims are still not completely backed by high-quality studies, but some evidence supports its use.

The grape seed extract is available as a dietary supplement in a liquid form, tablets, or capsules. Supplements commonly contain between 50 and 100 milligrams (mg) of the extract.

This article provides details on the benefits of grape seed extract as well as the side effects and precautions associated with its use.

Fast facts on grape seed extract

Here are some key points about grape seed extract. More detail and supporting information is in the main article.

Some evidence shows that grape seed extract might aid wound healing.
Grape seed extract should be avoided during pregnancy.
Some researchers believe that the proanthocyanidins it contains hold a range of benefits.

Studies on animal models have revealed that grape seed extract can be effective in treating heart disease.

Some experts think that grape seed extract could even have anticancer and cancer chemopreventive potential.

Over recent years, there has been a great deal of research pointing to the possible therapeutic properties of grape seed extract. Listed below are some of the key findings.
Healing wounds
A grape seed extract has the potential to increase the speed at which wounds heal. A study, published in the journal Free Radical Biology and Medicine, applied proanthocyanidin extract onto wounds on the backs of mice. They found that the mice treated with this solution had quicker healing times.

According to the researchers they “provided firm evidence to support that topical application of GSPE [Grape seed proanthocyanidin extract] represents a feasible and productive approach to support dermal wound healing.”

Although it is not clear how this protection occurs, GSPE was found to increase the production of vascular endothelial growth factor, a compound important in the wound healing process.
Improving bone strength
Including grape seed extract in your diet with calcium has a “beneficial effect on bone formation rested and bone strength for the treatment of bone debility caused by a low level of calcium.”

This is according to a study published in the Journal of Musculoskeletal & Neuronal Interactions that investigated the effects of calcium and proanthocyanidins on the bone structure of mice that had been fed a low-calcium diet.
Anti-Candida activity
A study conducted in Italy examined grape seed extract’s ability to attack Candida, a yeast-like parasitic fungus that can, sometimes, cause thrush. The grape seed oil contains flavan-3-ols. The researchers concluded:

“The results pointed out a significant inhibition of Candida albicans load 5 days after challenge. These findings indicate that grape seed extracts with high content of polymeric flavan-3-ols can be used in mucosal infection such as vaginal candidiasis.”
Preventing skin cancer
Grape seeds contain proanthocyanidins which might prevent the development of cancer. A study, published in the journal Molecular Nutrition & Food Research, found that grape seeds have properties that can reduce the severity of skin cancer.

Using hairless mice, the research team tested the ability of grape seed proanthocyanidins to slow the formation of skin tumor development.

The researchers concluded that grape seed extracts “could be useful in the attenuation of the adverse UV-induced health effects in human skin.”

It is thought that the protective nature of proanthocyanidins comes via a number of routes including a reduction in oxidative stress and immunosuppression by altering cytokine activity. Further research is needed to firm up the findings.
Cardiovascular benefits
The antioxidants in grape seed extract can potentially protect the blood vessels from becoming damaged, which may prevent high blood pressure.

According to one study, published in the journal Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, “grape seed proanthocyanidin extract (GSPE) provides superior antioxidant efficacy as compared to Vitamins C, E, and β-carotene.”

The National Center for Complementary and Integrative Health (NCCIH) note that it may help reduce systolic blood pressure and heart rate, but they point out that it will not help decrease lipid levels, for example, cholesterol, in the blood.
Preventing cognitive decline
The grape seed extract is very high in proanthocyanidins which some belief could prevent cognitive decline.

One study identified “a critical role for grape seed proanthocyanidin extract (GSPE) as a neuroprotectant in the hippocampus and in preventing cognitive loss with aging.”

The NCCIH is supporting studies on the effect of grape seed extract on Alzheimer’s disease.
Other possible benefits
Other possible benefits associated with grape seed extract include:

Grape seed extract contains proanthocyanidins

treating tooth decay
protecting against pathogens
improving night vision
Alzheimer’s disease
treating diabetic retinopathy and improving blood sugar control
relieving symptoms of chronic venous insufficiency
anti-aging properties (protecting collagen and elastin)
reducingTrusted Source edema
relieving symptoms of chronic venous insufficiency
reducing iron levels in people with hemochromatosis
reducing inflammation

Estrogen plays a substantial role in breast cancer. Some animal studies inferred that grape seed extract might work to alter estrogen levels.

However, a study in 2014 showed that four daily doses of grape seed extract “did not significantly decrease estrogen or increase androgen precursors.”

Preventing hair loss by consuming grape seed extract has been theorized. Some nutritionists believe that proanthocyanidins inhibit dihydrotestosterone (DHT), one of the hormones thought to be involved in hair loss but, evidence for its effectiveness is scant.

Side effects
Common side effects include:

headache
sore throat
dizziness
itchy scalp
stomach ache
nausea

It is important to talk to your doctor before taking grape seed extract as it can affect the way that certain medications are broken down in the liver.

Grape seed extract might also act as an anticoagulant or blood-thinner. It could increase the risk of bleeding if taken with other blood-thinners such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin.

The NCCIH describes grape seed extract as “generally well tolerated when taken in moderate amounts.”
