ActiGrape™ Grape Seed Extract


Grapes (and their seeds, leaves and sap) have been used in Europe as traditional treatments for a whole range of health issues for THOUSANDS of years.

ActiGrape™ is a highly effective dietary supplement containing an activated grape seed extract - naturally derived from ground-up seeds of red wine grapes (the healthiest part of the grape).

Ever heard red wine is an antioxidant? Well, so is grape seed extract.

Not only does it contain antioxidants, taking grape seed extract as a dietary supplement has been linked to wide range of beneficial effects, supporting:

  • Healthy blood circulation & cardiovascular function
  • Antioxidant effects (destroys free radicals)
  • Promoted energy & cellular health
  • Healthy aging

As more research on grape seeds emerges, it becomes clearer and clearer that supplementing them regularly can have wide-reaching health benefits!

Antioxidant, Promoting Healthy Blood Circulation & Cardiovascular Function.

ActiGrape™ is an all-natural grape seed extract that contains over 95% polyphenols. These are the beneficial antioxidant compounds commonly found in grape seeds. 

It’s also packed with natural resveratrol and antioxidants like linoleic acid, phenolic procyanidins and flavonoids. Plus - it contains oligomeric proanthocyanidin complexes (or OPC).

All of these ingredients are well known for their antioxidant activity. They support a healthy blood pressure, and a healthy response to blood vessel damage

Grape seed extract is scientifically shown to promote a healthy blood circulation and cardiovascular function, and even natural energy production and cellular regeneration in healthy individuals.

A Look at the Potential Health Benefits of Activated Grape Seed Extract (GSE)

  • Supports the Cardiovascular system
  • May support Healthier Skin
  • Helps to maintain and promote Cellular Energy
  • May support Healthier Aging
  • May help to support efficient Control of Oxidative Stress during Exercise 

Many people have heard of the French Paradox. Despite eating a hearty and fat rich diet, the French population has one of the lowest incidences of heart and coronary conditions of any western nation. Many reasons have been put forward for this, with perhaps one of the most prominent being the consumption of wine. 

As good wines are produced from high quality grapes it is no surprise to learn that grapes, especially the resveratrol compound found in their skins, are a rich source of healthy bioactive compounds. Likewise, their seeds contain a rich source of bioactive substances, such as catechins, flavonoids, and flavonol esters. such as the antioxidant catechins, flavonoids, and flavonol esters. 

Grape seed extract (GSE) naturally contains large amounts of procyanidins (Proanthocyanidins). These polymer chains are formed from (+)-catechin and Procyanidin B2. GSE is also rich in Procyanidin B1, C1, and epicatechin.

The Procyanidin B1 compounds present in grape seed extract can be readily absorbed by humans following digestion, and are able to circulate within the blood serum [1]. The catechins found in grape seeds have been reported to have a similar level of absorption and bioavailability as green tea catechins, which are thought to support numerous human health aspects [1]. However experimental studies using rats have suggested that absorption may not be as effective across intestinal cells [2]. This makes it important to take GSE alongside piperine to prolong its longevity in the human system.

Black Pepper for Better Absorption and Retention of GSE Catechins

Our grape seed extract contains black pepper extract (BPE). The active ingredient in BPE is bioperine, which itself is derived from piperine [3]. This bioactive compound may help the body to better retain GSE and other supplements in its system. 

Without the use of BPE, enzymes in the liver catalyze the bonding of glucuronide to supplement and pharmaceutical molecules; this in turn targets them for removal from the body via the urinary system. So without the use of BPE, much of the beneficial aspects associated with GSE supplementation will be nullified, as it will not stay in the body long enough to be effective. 

Cardiovascular System and Cholesterol Support

The bioactive compounds present in GSE may help to support heart rate and healthy blood pressure levels.

Consumption of GSE has been reported to increase levels of the signaling molecule nitric oxide in rats, at both rest and during exercise [4]. Nitric oxide is known to widen blood vessels through a process known as vasodilation [5]. The authors speculated the reason why GSE helps to prevent oxidative stress in rats during exercise is through an increase in the activity of antioxidant enzymes and through the prevention of lipid peroxidation [4].

A small trial in postmenopausal women suggested that GSE might help to support blood flow [6]. It also may help to support blood flow in the legs of people sitting down for a prolonged amount of time [7].

It is possible that GSE may also help to support total cholesterol levels at a healthy range, and that tablets containing 200 or 400 milligrams of GSE may have beneficial effects on oxidized LDL [8]. 

Body Weight and Blood Sugar Control

 Research in rats suggests that GSE dosages are able to lower the circulating quantity of adiponectin [9]. This protein is known to be involved in the modulation of both lipid and glucose metabolism [10]. This suggests that grape seed extract may play a role in the regulation of triglycerides and blood glucose levels.

Further to this, GSE has been demonstrated to affect appetite suppression in rats [11]. The authors reported that polymeric grape seed tannins had a beneficial effect on intestinal metabolism, and also helped to protect the colon through decreasing the activity of fecal bacterial enzymes. In humans, GSE may also help to support the control of appetite; this is thought to occur through bringing about increased feelings of satiety and by cognitive enhancements of mood [12].

Hormonal interactions

Grape seed extract may be able to help support healthy levels of estrogen and testosterone. It may do this indirectly by supporting the protection of testicular tissue against damage from alcohol toxicity [13]. The authors noted that GSE might prove a useful herbal remedy as it may have a role in the control of oxidative damage.

GSE may also play a role in the support of membrane androgen receptor agonists. This is likely to be because of the presence of catechin and epicatechin; these are also found in green tea. [14, 15] 

Aesthetic Properties

When grape seed extract was taken in conjunction with fish protein polysaccharides, extracts from white tea, chamomile, soy, and tomato, and vitamins C and E, and zinc it was reported to support skin health qualities such as structure, firmness, and condition in post-menopausal women [16].

What are the main ingredients in ActiGrape?

This supplement contains a 300 mg dose of grape seed extract, of which 95% is in the form of proanthocyanidins. It also contains 3 mg of black pepper extract. The presence of Bioperine in our products helps the body to better absorb and retain proanthocyanidins, this is one of the many reasons that we feel our supplements are far superior to our competitor’s less effective GSE products.

Are your products suitable for vegetarians?

Yes, our gluten free Vegicaps are designed with vegetarians in mind.

Are there any known treatment side effects of grape seed extract, is it safe?

The research evidence suggests that grape seed extract is usually well tolerated when taken orally [17]. The NIH notes that it should probably be avoided by people taking anticoagulants (such as aspirin or warfarin), and those who have a bleeding disorder, or are about to undergo surgery. They also report that minor side effects may include, but are not limited to, itchy scalp, nausea, dizziness, headaches, and higher blood pressure. As with any other drug or supplement it is important to discontinue use if you suffer from any side effects. It may be a good idea to consult a doctor or a medical practitioner for professional advice before taking any form of dietary supplements. 

What foods contain grape seed extract, how can I include it naturally in my diet? There are two main types of grape (Vitis vinifera) sold at groceries and supermarkets, seeded and seedless. You will need to stick to eating seeded varieties if you want to include them in your diet, unfortunately these seem to get stuck in your teeth and many people cannot tolerate this; you will also need to consume large quantities of grapes every day for weeks on end. The seeds will also pass straight through your body unless you chew each one of them.

Where can I buy High Quality Grape Seed Extract?

Rest assured that all of VitaMonk’s supplemental products are of a very high quality. What’s more our GSE capsules also contain black pepper extract, this greatly increases the activation level and efficiency compared to other makes. They are available for sale online here (free shipping on orders over $35), or you can buy them on our Amazon store. 

Which is better grape seed extract or resveratrol?

You will be happy to know that we have both of these products for sale. Resveratrol, which is often taken alongside grapefruit extract, tends to be shorter lived in the blood system. GSE also contains additional proanthocyanidin (OPCs) polyphenol complexes and significant substances that may be of benefit to human health.

Where does grape seed extract come from?

It is derived from whole grape seeds.

Does GSE inhibit aromatase? 

It has been shown to be involved in inhibition of the enzyme aromatase in vitro.

Who should take grape seed extract? Men and women wishing to support their cardiovascular health and blood circulation, and those looking to enhance the levels of antioxidants that they consume.

What does grape seed extract do for skin? 

It is thought that it may be beneficial for overall skin quality.

When to take grape seed extract?

Most people take it daily. The daily RDA has not been established, but many people tend to take 150 to 300 mg per day. Each VitaMonk ActiGrape™ capsule contains 300 mg of GSE.
