Grape Seed Extract Powder


  • Contains anti-aging properties
  • Promotes overall health
  • Non-GMO
  • Taste

  • Mixability

This particular extract is taken from the seeds of the vitis vinifera, L (a type of grape plant usually used to make wine). Polyphenols are particularly strong antioxidants and can be found in high concentrations within the seed of this plant. Grape seed also contains procyanidolic oligomers.


Serving Size & Timing

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

There are no fillers of any kind present in this supplement, and it is considered food grade and vegan friendly.

There are many ingredients in Grape Seed powder meant to promote general health such as polyphenols, lipids, carbohydrates and flavonoids. One unique component of Grape Seed Extract is Procyanidin. This nutrient helps maintain comprehensive oral health as well as health of bones, hair, skin and other body tissues. Grape Seed Extract also has Resveratrol, an antioxidant that is particularly useful in helping with cardiovascular health.


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. If allergic to grapes, this supplement should be avoided.


Grape Seed Extract will blend surprisingly well when mixed with water or juice. It can even be taken with or on food. Servings larger than 100mg of the supplement will probably be a bit too bitter for most 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. This product should be stored in an area that is free from light, heat and moisture.

Supposedly Good for Circulation
I mix a little in my morning smoothie as I've heard grape seed extract is great for a number of things, including circulation. I haven't really noticed any effect one way or the other, but continue to use it under the assumption that it is increasing my overall wellness.*

I put this powder into gel caps as it has a slightly bitter taste. While it is too early (due to the 10-day review deadline) to give it a full review, I am a huge fan of Bulk Supplements and trust the company and their products. This product is economical compared to purchasing grape seed extracts at the store.*

Grape Seed Extract
I had heard of the benefits of grape seed extract years ago, but age has given me more reason to try it. I'm diabetic and need to lower my blood pressure and improve circulation. Along with exercise, I'm hoping to improve in these areas. A little relief in joint pain sounds good also, as other reviewers have noted. *

On 6/3/2018 DAVID said...

A proven heart friendly supplement
This is my first order of grape seed extract. As others have mentioned it is bitter and astringent to the taste. Plan to encapsulate or mix with something else. It worked faster than I expected to lower my blood pressure. I can definitely feel my heart laboring less under exercise as well. It is a small dose, so it goes a long way.*

On 5/8/2018 Kimberly said...

Grape Seed Extract Powder
This has the distinct taste and smell of grapes. The color is a true grape seed color. It mixes well with juice. I have been taking this as directed and seems like I can already tell a difference in the way my joints are feeling. Shipping was secure and fast. I am well pleased with my purchase and will tell my friends.*

"Grape Seed Extract Powder
Came in great time, as usual for BS. Excited to try for the effects it has on lung function. An immediate result! I don't smoke, but I do cough in AM and thru the day. Finding out I don't cough hardly at all after taking. Also, as a singer, am able to hold the notes longer and with greater ease! Will continue to take as part of my other products from BS. Thanks again for a great product!*

Lower blood pressure and help circulation
This is the second time that I ordered grape seed from I share it with other senior family members and relatives. Greed seed extract helped me lower my blood pressure. My blood pressure now is around 112/70. Also when I play basketball, I no longer feel short of breath. I usually eat it mixed with yogurt to lessen the strong taste of it. The price from this site is great.*

Grape Seed Extract Powder
I requested this as a free sample . Although I well know the benefits of GSE , I never had the opportunity to try the effects for myself . After taking it (as prescribed) for over a week , I can feel a tremendous difference in my ability to move and walk . Also I sleep and feel better than before . Although the best antioxidant is Earthing or Grounding (walking in wet grass or on a wet beach) , this is a great antioxidant for those who have no access to those things . I will definitely order this Grape Seed Extract again from Bulk Supplements .*

Grape Seed Extract 100 grams
I received this as a sample. I have used GSE caps before from brand name companies, but never used the pure powder before so I was looking forward to trying this.

The sample I received from BS:
Color: dark burgundy/purple color to it
Consistency: very fine micronized powder
Smell: fresh woody
Taste: bitter and slightly astringent/tannic quality

I put some dry powder on my tongue and it tasted like grapseed when you bite into them. The taste was slightly bitter and ahd an astringent/tannic quality similar to drinking strong coffee, tea, or red wine. I tried some in water and it dissolved quickly and easily. It also turned the water a burgundy/purple color same like the powder. I then capped the rest of it using size 0 gelatin caps and got over 200 caps. It was messy to cap though as the powder was so fine it stuck to everything due to static cling from being such small fine particles. Overall this is good quality and value. I will probably buy more after I use up these caps. Thank you BS.*

Great Product
If you take pine bark extract power you need to add grape seed extract powder to your mix. Using these two together gives me the energy and the stamina I need to make it through the day. My concentration is even better and I feel like my old self again. If you want to feel mentally like you used to, buy this product!*

Grape seed extract
My dermatologist recommended that I use Grape Seed Extract for healthier skin and to deter skin cancer. I received the order 2 days after ordering. The powder is just beautiful, a deep purple brown color. it smells and looks so fresh. It is very bitter and astringent. Just a taste from the tip of my finger made my whole mouth pucker. That is why I am putting into capsules and not in my smoothies.*

new to Grape Seed
I wanted to give this product a shot ever since reading some reviews and thinking it could be a good addition to my pre-workout arsenal. I read that it's a natural vasodilator so am giving it a shot. I'm only taking it every other day and it's been 2 weeks. I will report back later to review effects I notice.*

Grape Seed Ext Powder
I am happy with this, however, I will have to purchase some capsules, because this is extremely bitter and will cake the inside of your mouth. Nothing that I drink helps. Why do I still take it? It helps with my circulation! There are a plethora of other supposed benefits, but I can't speak for those.*

Great Grape
I received my first package of grape seed extract within just a few days of ordering. The powder was a little finer than I had thought but it flowed into capsules better than I thought it would. I surprised to see that the powder was a dark grape color. I was thinking it would be sort of pail brown - like the seeds. It's probably too early to say how well it's working but the product seems to be of excellent quality. *

Order came timely and we are very glad about this product as my wife has healing for hands able to feel alive with better circulation. Extremely noticeable the first night. Instead of hands feeling like they are asleep she can rest at night with good circulation and not have to think about why her hands feel asleep. Praise the Lord for this good find and thanks for marketing it for us. *

Great quality powder, mixes super and has a pleasant taste. And as always the ordering/shipping experience from Bulk Supp is top notch!*

I like the quality. Mixes into my protein shake very well. If you study this supplement - you might find it beneficial to take long term - however you should cycle on and off with this stuff. It can thin your blood but that may be very good for some people. I suggest looking grape seed up at WebMD - and learning about it before taking it blindly. It is high quality from Bulk no doubt - 5 stars*

Grape Seed Extract Powder
I used to buy this from another company. I received a sample of this from Bulk Supplements. When I received it, I found it to be a much darker color than the former. I believe this to be due to it being more concentrated. Because of this, I will continue to buy for Bulk Supplements.

Love the color :)
Just got my grape seed extract powder today. Can't comment on it's effect long term but I can give you some info. First of all, it is a beautiful burnt orange color. Super acrid but, they tell you that on the package...that it's bitter so, no surprise there. I haven't tried it in a smoothie It could be that the bitterness may not be noticeable in that amount of liquid but, like I said, I haven't tried that yet. Another option (which I'll be doing) is gelatin capsules. Put the recommended amount in each capsule and you won't taste a thing . The dosage is between 1/64th teaspoon and 1/16th teaspoon a day. How do you measure that amount? Well, lucky me I had recently bought Norpro mini measuring spoons and they work perfectly. They are named: Tad, (1/4 tsp) Dash (1/8), Pinch, (1/16) Smidgen (1/32) and Drop (aprox 1/64 tsp). Got them just in time too since I've been using them to measure my Bullk Supplements Hyaluronic Acid too. I just scoop the recommended amount into a capsule. Here's hoping I see some good results. Says it's good for circulation and me and hubby both can use help in that area. *

trying to reduce oxidative stress
I'm taking GSE to try to reduce oxidative stress. I already have a lot of damage that has occurred over the last year of taking a medication, so it's difficult to tell if it's working. I will be monitoring my skin closely, however, and looking to see if it seems to arrest the spread of these tiny little lines. It is not just a visual concern (though the impact of that cannot be discounted): I am sure there are other consequences of oxidative stress. The skin is an indicator.*

Grape seed extract
I ordered grape seed extract to see whether it will help with my general health condition. I searched on the web and found out ordering from bulk supplement web site would be the most economical way. The order processed so fast and shipped right away. I got it in only a couple of days. The power tastes bitter but I guess it is how it tastes. The only drawback is that the bag won't zip well after being opened. I wish they provide the expiration date on the website so that I know how much I should order. I don't know how it will help with my general health yet with only a couple of days' usage.*

Grape Seed Extract
Just received my grape seed extract and too soon to notice any improvements. I'm hoping to improve my immunity and also lower my blood pressure. I'm also taking pine bark extract from Bulksupplements.
I received a complimentary package of ascorbic acid from Bulksupplements for a recent review. I have taken vitamin C for many years, but always in pill form, and loaded with fillers. All of Bulksupplements products are pure without any fillers, so I'm anxious to see how this pure vitamin C works. *

A little of this grape seed extract goes a long way (1/4 tsp is probably more than enough). It's rather tannic, but the taste was barely noticeable in a shake that I made. *

Good Product
I was worried when I ordered this that the taste would be difficult to mask, however after mixing it with the supplements I already take, I found no noticeable difference in the flavor. The product is very finely ground and mixes fairly well. The only down side I've found is that the bag got shaken up during shipping and the fine powder got into the ziploc seal making it very difficult to seal.*

You know it's pure!
We received this product quickly, as usual with this company. The powder is a beautiful red. It is obvious that it is the pure powder. The taste is quite bitter...but as the saying goes... a spoonful of sugar (better yet stevia) makes the medicine go down in a most delightful way!!

The newer bags are nice, but can't be resealed because the powder gets in the seal due to the fineness.

We are taking this to increase our nitric oxide level, but haven't yet seen a change.*

This is my first time using this company. I was happy to receive my order

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*

Many diverse benefits
The following is a list of the many diverse benefits of grape seed extract (GSE). Abstracted from MEDLINE (GreenMedInfo):

1. Garlic and grape seed supplement use is inversely associated with hematological malignancies.
2. GSE reduces blood pressure, a cardiovascular risk marker.
3. A GSE reduces the inflammatory response and oxidative stress in patients with systemic sclerosis.
4. A multi-nutrient mixture of soy extract, fish protein polysaccharides, extracts from white tea, grape seed, and tomato, vitamins C and E as well as zinc and chamomile extract improves signs of skin aging in postmenopausal women.
5. GSE significantly improved markers of inflammation and glycaemia and a sole marker of oxidative stress in obese Type 2 diabetic subjects at high risk of cardiovascular events over a 4-week period, which suggests it may have a therapeutic role in decreasing cardiovascular risk.
6. Grape seed procyanidin decreases plasma levels of triglycerides.
7. Niacin-bound chromium and GSE can decrease total cholesterol and LDL levels significantly.
8. Aged garlic extract and grape seed proanthocyanidin protect against doxorubicin-induced cardiotoxicity.
9. Chronic consumption of a moderate dose of grape seed proanthocyanidin extract can correct an energy imbalance in a situation of diet-induced obesity, thereby improving the mitochondrial function and thermogenic capacity.
10. GSE prevents age-related oxidative protein damages in the central system of rats.
11. Dietary feeding of GSE prevents intestinal tumorigenesis in mice.
12. Grape pomace extract suppresses postprandial hyperglycemia in diabetic mice.
13. GSE attenuates silica-induced pulmonary fibrosis in rats.
14. GSE exhibits preventive and/or therapeutic potential in an animal model of Alzheimer's Disease.
15. GSE has a protective role against doxorubicin-induced cardiotoxicity and genotoxicity in albino mice.
16. GSE has a rejuvenating effect in the central nervous system of aged rats.
17. GSE has a therapeutic effect on oxidation-associated nerve damage in diabetic rats.
18. GSE has bactericidal effects on MRSA.
19. GSE inhibits advanced human prostate tumor growth and angiogenesis and reduces insulin-like growth factor activity.
20. GSE inhibits in vitro and in vivo growth of human colorectal carcinoma cells.
21. GSE prevents acetaminophen-induced cell death in the mouse liver.
22. GSE prevents gentamicin-induced nephrotoxicity and genotoxicity in bone marrow cells of mice.
23. GSE protects against cisplatin-induced oxidative stress in rats.
24. GSE supplementation prevents high-fructose diet-induced insulin resistance in rats by improving insulin and adiponectin signalling pathways.
25. GSE, black seed extract and curcumin ameliorate tamoxifen-induced liver injury.
26. GSEs reduce oxidative stress associated with cardiovascular disease in diabetic rats.
27. Grape seed proanthocyanidin inhibit advanced glycation end products in diabetic rats.

best price I've found anywhere
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.*

Great product from a very reliable company
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.*

Grape seed to go
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.*

Makes this 65-yr-old Feel Younger
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.*

Helps cronic venous insufficiency
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".*

great Vasculator
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.*

Grapeseed Extract Powder
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.*

Helped with circulation
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. *

Works well for sex in combination with l-arginine, pycnogenol, and gingko biloba.
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! *

Grape Seed Extract Powder
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. *

Works just as well as Solgar
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!*

Good Quality Grape Seed Extract
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.

Not too shabby
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.*

It make my morning drink taste like grapefruit juice.*

Product Questions

Does your grape seed extract contain tannins? Is the grape seed extract the French kind? The reason I am asking this is because I read a little booklet on grape seed extract and it said the best kind to buy was the one without tannins and that had French Grape (Vitis vinifera) seed extract standardized to contain greater than or equal to 90% polyphenols and greater than or equal to 80% OPCs (Tannin fFee)
