Grape Seed Extract Powder

Key Features

  • An Anti-Aging Wonder
  • Nature’s Biological Response Modifiers
  • May Help To Prevent Senility
  • Taste

  • Mixability

Grape Seed Extract is beneficial for humans in that it contains Antioxidants, Procyanidins, and Polyphenols which all serve to protect healthy cells from being damaged by rogue molecules called free radicals.

This particular extract is taken from the seeds of the Vitis Vinifera, L. This is a type of grape plant that is usually used to make wine. Polyphenols are particularly strong antioxidants and can be found in high concentrations within the seed of this plant, which is where this extract is derived from. It also has Flavonoids, which have Antioxidant properties as well, and Phytochemicals which are known to have effectiveness to rival the standard Vitamins C, and E.


Serving Size & Timing

Grape Seed Extract should be taken in servings of 250mg two times per day depending on intended effect. This is equal to about 1/16tsp. No more than 500mg per day should be taken unless specifically told to do so by a medical professional.

There are no fillers of any kind present in this supplement and it is considered food grade meaning it is safe for consumption.

Grape Seed Extract Side Effects

While some have reported minor issues such as headache, itchiness of scalp, dizziness, and even nausea, these reports are rare, and all occur in subjects who have taken above the recommended dosage. Also, if allergic to grapes, this supplement should be avoided.

Grape Seed Extract Solubility

Grape Seed Extract will blend surprisingly well when mixed with water or juice. It can even be taken with or on food. Taking servings larger than 100mg the taste of the supplement will probably be a bit too bitter for anyone to tolerate. Those with sensitive stomachs or taste buds may want to consider having gel caps filled with this extract in order for accurate consumption. Because the most important ingredient in this extract, Proanthocyanidin can survive in the body for up to 3 days, Grape Seed Extract should be taken every other day to maintain balanced levels of this chemical in the body. This product should be stored in an area that is free from light, heat, and moisture.

Customer Reviews

Ordered 1kg. The powder is fine and the solubility is indeed very good. As mentioned, it is quite bitter and will destroy all drinks when mixed too much.

This is my first time using this company. I was happy to receive my order
within a week of ordering under the free ship offer. I also liked the packaging it came in (light proof) protection from degradation and oxidizing. The powder
is a bit bitter but works well in smoothies and not to well in straight water. It is
too soon to gauge any benefit as it has been only a few days for me. I do use other ptroducts of similar type but will respond about my experience within the next 6 weeks. Oh and let me say i love the price point. Can't beat to you soon...sincerely Anthony

ordered 1kg. The package doesn't state anywhere that it's 90% Proanthocyanidins, just that it's a Grape Seed Extract with no other ingredients... but I trust BulkSupplements doesn't mean BS ))) & that I received exactly what I ordered. Also it expires in less than a year - I was hoping it would last longer, so I'm freezing most of it... Other than that it's what I expected.

I have continued to get amazing value from this company and the grape seed extract is no exception. This company is totally devoted to customer satisfaction and their products bear this . I will continue to come back to Bulk Supplements for all of my anti aging needs.

This is a wonderful company and I have learned to expect only superior service and quality as well as a very reasonable price for some otherwise expensive nutrients. The grape seed extract gives me a lift as well as a good addition to my anti-oxidant program. I will continue to come back to bulk supplements for my anti aging needs.

As a flight attendant we are exposed to more radiation than many people would think. I decided to preserve myself the best I can through taking this grape seed extract for it's antioxidants. Flavor doesn't bother me much at all, especially when mixed with juice. I'm also taking this for overall male body (parts) health benefits. No complaints thus far.

I've been taking grape seed extract capsules for years (tiny amount, very expensive). Swiched to bulk---about 2 teaspoons per day---and am feeling noticeably younger. No adverse effects.

Taste is not too bad; I put the 2 teaspoons in about 1/2 cup of stevia-sweetened rasberry tea and chug it. The taste of that mixture could be called unpleasant---but not really. The taste is akin to a raw vegetable taste, mildly unpleasant but hardly noticeable.

I have chronic venous insufficiency. This is supposed to help with that. I've put it in my smoothies or oatmeal for 2 months now. Does seem to be helping. Legs are not as "heavy".

I started adding 200 mg of this to my preworkout. this stuff works great with arginine, makes my veins pop out and my skin looks smoother. with that being said its tough to dose due to it being very fine and tacky.

On 9/18/2014 Brian C said...

Bulk Supplements definitely delivers. This is very high quality grape seed extract powder. The powder is dark in color, very astringent, and bitter, so be prepared. It does not dissolve well in cold liquids. It is a very good deal for the price. You will need measuring spoons to measure the correct dosage. I am happy with my purchase, and would buy it again.

On 9/16/2014 Kelli said...

I am a new customer of Bulk Supplements and I must say, So far, So good! I received my order promptly. The product came in foil air tight bags with instructions printed on label. I take Grapesee Extract along with Pine Bark extract and they have worked wonders for my circulatory system and over all well being.

I take a 1:1:1 mixture of pycnogenol, gingko biloba, and (recently) grape seed extract (120 mg twice a day of each) along with 2.5 grams of l-arginine once a day, and have noticed a great improvement in the quality of my erections (as has my wife). I had the temporary side effect of headache after adding the gingko to the mix, but after that only saw benefit after taking the combo for 2-3 weeks, all at a great price. Try it!

On 9/11/2014 Jim said...

This is definitely a bargain. I have taken grape seed extract for years due to its antioxidant benefits. Grape seed extract is very expensive. The best price I have found is 180 capsules for 39.95. I made 235 capsules from the 100g pouch for only 13.00.

On 8/28/2014 lousan said...

Bought this to replace my Solgar grape seed capsules. I am trying to rid myself of too much magnesium stearate. This was the perfect answer. I mix it in my smoothie, sometime my tea (depending on the flavor). They company told me this product comes from France so I am assured of it's quality. Great product at a great price. Thanks!

This is a very nice quality Grape Seed Extract. I found BulkSupplements shortly after my former supplier decided to stop making up and selling their own powdered form of the supplement. I guess they decided it was easier to just stock the same old brands (pill form) that all the other companies carried.

I take this Grape Seed Extract along with Pine Bark Extract mixed together in either orange juice or grape juice. Both supplements have a woody taste (because they come directly from woody substances), but the taste is fine once they are mixed in juice. Each supplement contains its own particular variety of "oligomeric proanthocyanidin complex" (OPC), one of the great natural discoveries of the 20th Century, in my opinion.

I first started taking OPCs many years ago in the form of Pycnogenol, which was fairly expensive because it had a patent on it. It’s so nice now to be getting OPCs at such reasonable prices.

Honestly, it has a strange vanilla pipe tobacco aroma to it that reminds me of what my dad used to smoke. Taste is okay when mixed with my amino acids in the morning. So far, seems to be working just fine. I like it.

On 4/13/2014 zac said...

I take this because I need vitamin C and I cannot take asorbic acid.
It make my morning drink taste like grapefruit juice.
