{"title":"OPC \/ Grape Seed Extract","description":"\u003ch2\u003eBuy OPC: grape seed extract in capsules and powder\u003c\/h2\u003e\u003cp\u003eOPC stands for oligomeric proanthocyanidins: a group of polyphenols that occur naturally in grape seeds. OPC supplements are usually made from grape seed extract, a concentrated extract of the seeds that remain after grapes are pressed for wine or juice. OPC itself has no approved health claims; in products with sufficient vitamin C (at least 15% of the reference intake per serving), the approved claims for vitamin C apply. Vitamin C contributes to normal collagen formation for the normal function of the blood vessels and skin, to the protection of cells against oxidative stress, and to the normal function of the immune system.\u003c\/p\u003e\u003cp\u003eIn this collection you will find OPC grape seed extract in various forms: high-dose capsules containing 1000 mg of grape seed extract from Vit4ever, combinations of OPC with natural vitamin C in capsules and powder, and the Wine OPC capsules from our own brand LUTO Supplements, standardised to 95% PCO and 30% OPC. This allows you to choose the form and dosage that best suits you.\u003c\/p\u003e\u003ch3\u003eWhat is OPC?\u003c\/h3\u003e\u003cp\u003eOPC is the abbreviation for oligomeric proanthocyanidins, plant substances that belong to the flavonoids, a subgroup of polyphenols. They can be found in grape seeds, grape skins, red wine, pine bark, and berries, among other things. In supplements, OPC is almost always extracted from grape seeds (Vitis vinifera), because they are naturally rich in these compounds. The term PCO (procyanidin oligomers) refers to the same family of substances and is often used in the standardisation of extracts.\u003c\/p\u003e\u003ch3\u003eWhat do OPCs occur naturally in?\u003c\/h3\u003e\u003cp\u003eOPCs occur naturally in grapes (especially in the seeds and skin), red wine, apples, cocoa, blueberries, cranberries, and the bark of the sea buckthorn. The amounts in ordinary food are relatively low compared to a concentrated extract. A grape seed extract supplement provides a concentrated amount in one or two capsules, without the calories or alcohol that, for example, are found in red wine.\u003c\/p\u003e\u003ch3\u003eCapsules or powder: which form do you choose?\u003c\/h3\u003e\u003cp\u003eCapsules are the most popular form: they are tasteless, easy to dose, and convenient for on the go. Powder is a good alternative if you prefer not to swallow capsules; you mix it with water, juice, or a smoothie. The powder in this collection combines grape seed extract with natural vitamin C from acerola. When comparing, pay attention to the amount of extract per daily dose and to the percentage of OPC or PCO to which the extract is standardised.\u003c\/p\u003e\u003ch3\u003eOPC with vitamin C\u003c\/h3\u003e\u003cp\u003eMany OPC supplements are combined with vitamin C, often from natural sources such as acerola cherries. Vitamin C contributes to normal collagen formation for the normal function of the blood vessels, skin, gums, and cartilage. In addition, vitamin C contributes to the protection of cells against oxidative stress and to the reduction of tiredness and fatigue, and vitamin C increases the absorption of iron. These claims only apply to products with sufficient vitamin C.\u003c\/p\u003e\u003ch3\u003eWhat does 95% PCO or 30% OPC mean?\u003c\/h3\u003e\u003cp\u003eGrape seed extracts differ greatly in concentration. A standardised extract states the percentage of polyphenols, PCO, or OPC that it contains at minimum. For example, LUTO Wine OPC contains an extract standardised to 95% PCO and 30% OPC. The higher the standardisation, the fewer milligrams of extract you need for the same amount of OPC. Therefore, do not compare supplements only on the amount of extract, but also on the standardised content.\u003c\/p\u003e\u003ch3\u003eDosage: how much OPC per day?\u003c\/h3\u003e\u003cp\u003eCommon dosages in supplements range between 100 and 500 mg of OPC per day, depending on the concentration of the extract. A capsule with 1000 mg of grape seed extract provides a portion of this as OPC, depending on the standardisation. You can spread the intake throughout the day and preferably take capsules or powder with a glass of water. Always follow the directions for use and the recommended daily dose on the packaging.\u003c\/p\u003e\u003ch3\u003eWho is OPC grape seed extract for?\u003c\/h3\u003e\u003cp\u003eOPC supplements are for adults who want to supplement their diet with polyphenols from grape seeds. The capsules and powders in this collection are vegan and free from unnecessary additives. Do you use medication, are you pregnant, or are you breastfeeding? Then consult a doctor or pharmacist before using a supplement.\u003c\/p\u003e\u003ch3\u003eWhat to look for when buying OPC?\u003c\/h3\u003e\u003cp\u003eWhen choosing an OPC supplement, look at: the standardised OPC or PCO content, the amount of extract per daily dose, the source of the extract (Vitis vinifera grape seeds), any additives such as vitamin C, and the price per daily dose instead of per jar. Large packages such as 300 or 365 capsules are often more economical per dose.

At Vit4ever, they don't end up in the compost heap, but are processed into \u003cstrong\u003eOPC grape seed extract\u003c\/strong\u003e, a concentrated source of oligomeric proanthocyanidins (OPC). This extract is standardized to 70 percent OPC and provides 1000 mg of extract, with 700 mg of OPC, when taking two capsules per day. A bottle contains 300 vegan capsules, enough for five months.\u003c\/p\u003e\n\u003ch3\u003eWhat OPC exactly is\u003c\/h3\u003e\n\u003cp\u003eOPC is the collective name for a group of polyphenols, plant substances that occur naturally in the skin and seeds of grapes, but also in, for example, cranberries and pine bark. Chemically, they are chains of flavan-3-ol molecules linked together. The extract is standardized to 70% OPC. What many people do not know: grapes build up these substances as a kind of natural protection of the seed against sunlight and insects. During the grape harvest, the seeds often remain as a byproduct of wine or juice production, and it is precisely in them that the highest concentration of OPC in the entire grape is found. Many people wonder whether OPC from grape seeds differs from OPC from, for example, pine bark; the difference lies mainly in the precise composition of the chains. Within the broader family of polyphenols, which also includes substances such as resveratrol and quercetin, OPC from grape seeds distinguishes itself mainly by the relatively short chain length and the high concentration that is bundled in this extract.\u003c\/p\u003e\n\u003ch3\u003eWhy 70 percent OPC is used as a standard\u003c\/h3\u003e\n\u003cp\u003eNot every grape seed extract is the same. The concentration of OPC varies greatly per manufacturer and per production method. Vit4ever standardizes the extract using the HPLC method (high performance liquid chromatography), a laboratory technique that accurately measures how much OPC is actually in the extract. At 70 percent OPC, you know that you receive 500 mg of extract per capsule with 350 mg of OPC, or 700 mg of OPC per day with two capsules. Without such standardization, you are effectively buying an extract whose actual strength can vary per batch, sometimes by a factor of two or more. The difference therefore is not in the name grape seed extract on the label, but in the number behind it. Vit4ever has each batch independently tested for the actual OPC content, so that the 70 percent on the label is really in the bottle. This control takes place separately from its own production, in an external laboratory, and is intended to prevent a batch with a lower content from still being sold.\u003c\/p\u003e\n\u003ch3\u003eFrom grape seed to capsule\u003c\/h3\u003e\n\u003cp\u003eThe path from grape seed to capsule takes a few steps: first, the seeds are separated from the rest of the grape, dried and ground, then follows an extraction process where the OPC-rich substances are separated from the fiber mass and concentrated into a powder. Only when the OPC content is at the required level does the powder go into the capsule.\u003c\/p\u003e\n\u003ch3\u003eA simple formula, two capsules per day\u003c\/h3\u003e\n\u003cp\u003eThe capsule from Vit4ever contains, besides the grape seed extract, only a plant-based capsule shell of hydroxypropyl methylcellulose. There are no fillers, colorings, or magnesium stearate in it, which makes this product suitable for those who prefer a short, recognizable ingredients list. The recommended intake is one capsule twice a day, for example one with breakfast and one with dinner. A bottle of 300 capsules of OPC grape seed extract will last five months in this way, which amounts to approximately 150 day doses. Store the bottle dry and dark, well closed and out of reach of direct sunlight, so that the quality of the extract is preserved until the last capsule.\u003c\/p\u003e","brand":"Vit4ever","offers":[{"title":"Default Title","offer_id":43775463031004,"sku":"vit4-045","price":27.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9006\/2812\/files\/vit4ever-opc-druivenpit-extract-300-capsules-1000mg-vegan-v-1.jpg?v=1793623867"},{"product_id":"opc-druivenpitextract-natuurlijke-vitmaine-c","title":"OPC Grape Seed Extract + Vitamin C | 240 \u0026 365 Capsules | Vit4ever","description":"\u003ch2\u003eOPC Grape Seed Extract + Vitamin C by Vit4ever\u003c\/h2\u003e\n\u003cp\u003eYour skin, blood vessels, gums and cartilage all have something in common: they are made of collagen. Your body needs vitamin C to produce it. That is why Vit4ever combines \u003cstrong\u003egrape seed extract with vitamin C\u003c\/strong\u003e: 450 mg of extract per capsule (of which 315 mg is OPC) and 75 mg of natural vitamin C from camu camu and rosehip. One capsule a day, available in a bottle of 240 or 365 capsules. This grape seed extract with vitamin C is designed for those who want to get both OPC and a generous amount of vitamin C in a single capsule, without having to keep two separate bottles in the cupboard.\u003c\/p\u003e\n\u003ch3\u003eVitamin C and the formation of connective tissue\u003c\/h3\u003e\n\u003cp\u003eVitamin C contributes to normal collagen formation for the normal function of the blood vessels, skin, cartilage, bones, teeth and gums. Collagen is the protein that serves as a kind of scaffold for these tissues: it gives them structure and cohesion. Each capsule provides 75 mg of vitamin C, or 94 percent of the reference intake.\u003c\/p\u003e\n\u003ch3\u003eMore than just connective tissue\u003c\/h3\u003e\n\u003cp\u003eVitamin C also contributes to normal energy-yielding metabolism, the normal function of the nervous system and normal psychological function. Vitamin C also contributes to the normal function of the immune system and to the protection of cells against oxidative stress. Furthermore, vitamin C contributes to the reduction of tiredness and fatigue, to the regeneration of the reduced form of vitamin E, and vitamin C increases the absorption of iron.\u003c\/p\u003e\n\u003ch3\u003eOPC from European wine grapes\u003c\/h3\u003e\n\u003cp\u003eIn addition to the vitamin C, each capsule contains 450 mg of grape seed extract, with 315 mg of OPC measured using the conservative HPLC method. This measurement method is considered more reliable than some alternative testing methods because it is less likely to indicate an excessively high percentage. For this purpose, Vit4ever uses grape seed extract from European wine grapes, obtained from the seeds that remain after the grapes are pressed for wine production. OPC stands for oligomeric proanthocyanidins, a group of plant compounds naturally found in the skin and seeds of grapes and belonging to the flavonoid family, the same large group that includes compounds from tea, cocoa and berries. Grape seeds naturally contain a relatively high concentration of OPC, which explains why these seeds are used as a source of concentrated extract: the extraction process removes the OPC from the seed and concentrates the compound into a powder that can then be incorporated into a capsule. This way, you get a quantity in 450 mg of extract that you would not practically achieve by eating grapes or drinking grape juice. OPC and vitamin C often occur together in the same plant sources in nature. Incidentally, the vitamin C in this formula does not come from synthetic ascorbic acid, but from camu camu and rosehip, two fruits that naturally contain a lot of vitamin C. Camu camu is a small, sour fruit from the Amazon region that is known for having one of the highest natural vitamin C contents among fruits; rosehip is the fruit of the wild rose and has long been used as a natural source of vitamin C in dietary supplements.\u003c\/p\u003e\n\u003ch3\u003eOne capsule a day, eight months' supply\u003c\/h3\u003e\n\u003cp\u003eYou take one capsule a day with a meal and plenty of liquid. The capsule also consists of a plant-based hydroxypropyl methylcellulose shell, without fillers, magnesium stearate, colorings or flavorings. The product is gluten- and lactose-free, GMO-free and vegan. A bottle of 240 capsules thus lasts eight months; those who prefer to stock up on a larger supply at once can choose the 365-capsule variant, good for just over a year's supply. Vit4ever has every batch tested by an independent laboratory for content and contaminants, so that the amounts of grape seed extract with vitamin C on the label match the actual contents of the capsule. This way, you know exactly what you are getting every day, without having to guess the actual strength. That combination of a fixed daily dose, a controlled content and a simple intake schedule makes this grape seed extract with vitamin C a format that is easy to fit into your daily routine, whether you are just starting with supplements or have been accustomed to a fixed morning routine for years.\u003c\/p\u003e","brand":"Vit4ever","offers":[{"title":"240 capsules","offer_id":50077289742674,"sku":"vit4-084","price":22.9,"currency_code":"EUR","in_stock":false},{"title":"365 capsules","offer_id":50077289775442,"sku":"vit4-405","price":24.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9006\/2812\/files\/vit4ever-opc-druivenpitextract-natuurlijke-vitmai-240-capsules-1.jpg?v=1793631165"},{"product_id":"opc-druivenpitextract-vitamine-c-poeder-300g-vit4ever","title":"OPC Grape Seed Extract + Vitamin C Powder | 300g | Vit4ever","description":"\u003ch2\u003eOPC Grape Seed Extract + Vitamin C Powder\u003c\/h2\u003e\n\u003cp\u003eSome people do not want to swallow capsules but would prefer to use a concentrated extract.

The difference lies in their origin: here, OPC comes from grape seeds, while vitamin C comes from acerola, a cherry-like fruit that naturally contains a lot of vitamin C. By combining both in one powder, you do not need to purchase two separate products. For people who already take several supplements, this also means fewer jars and bags to prepare each day.\u003c\/p\u003e\n\u003ch3\u003eVitamin C from acerola\u003c\/h3\u003e\n\u003cp\u003eVitamin C is a water-soluble vitamin that occurs naturally in fruits and vegetables. The manufacturer does not state the exact amount of vitamin C per serving. Therefore, we do not make any health claims about vitamin C on this page. Take the recommended amount daily at the same time so that it easily fits into your routine.\u003c\/p\u003e\n\u003ch3\u003eWhy acerola instead of synthetic ascorbic acid\u003c\/h3\u003e\n\u003cp\u003eMany vitamin C supplements use synthetic ascorbic acid, which is chemically identical to the vitamin C found in fruit. Vit4ever deliberately chooses a natural source: acerola extract. This fruit grows in tropical regions and naturally contains one of the highest concentrations of vitamin C found in fruit. The difference is not in the vitamin itself, as it is the same molecule, but in the source from which it is extracted and the additional plant compounds that remain in the extract. Acerola grows mainly in Central and South America and is often used as a natural source for supplements because of its high vitamin C content, rather than producing the vitamin synthetically in a laboratory. What many people do not know is that acerola also contains several other plant compounds that naturally end up in the extract when the fruit is processed in this way. This keeps the extract close to the original fruit, rather than being an isolated, purely synthetic molecule.\u003c\/p\u003e","brand":"Vit4ever","offers":[{"title":"Default Title","offer_id":50418467078482,"sku":"vit4-422","price":24.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9006\/2812\/files\/vit4ever-opc-druivenpitextract-vitamine-c-poeder-1.png?v=1793698733"},{"product_id":"opc-druivenpitextract-95-pco-30-opc-90-capsules-luto-supplements","title":"Wine OPC Grape Seed Extract (95% PCO - 30% OPC) | 90 Capsules | LUTO Supplements","description":"\u003ch2\u003eOPC Grape Seed Extract Capsules with 95% PCO\u003c\/h2\u003e\n\u003cp\u003eIf you have ever looked into plant-based polyphenols, you have probably come across \u003cstrong\u003egrape seed extract\u003c\/strong\u003e.

PCO stands for procyanidin oligomers. It sounds complicated, but here is the bottom line: grape seeds contain all kinds of polyphenols. Some are small molecules, while others form long chains. The small, oligomeric variants are the OPCs and PCOs. That is why standardization matters. A grape seed extract without specification can contain anything.

This has to do with measurement methods. OPC and PCO partially overlap. They belong to the same family of polyphenols from grape seeds. The PCO percentage (95%) indicates the total oligomeric procyanidin fraction. The OPC content (30%) is a more narrowly defined subset of that. In practice, this means: you get an extract with a fixed proportion of oligomeric procyanidins.
