Vináli is Nutrifii's vitamin C and grape seed extract capsule. We sell it.
An earlier version of this page listed nine named diseases in a single bullet list and went on to claim relief from several more. All of that is gone. What is below is what the ingredients actually are and what they are actually for, which is a shorter and more useful article.
What is in it
- 310 mg of vitamin C a dose, from mineral ascorbates and whole food sources including green pepper and acerola cherry. - Grape seed extract, whose active components are a group of compounds called OPCs. - Bioflavonoids alongside the vitamin C.
The full panel is on the product page.
What vitamin C is genuinely required for
This part is not marketing and is worth understanding properly, because it is also the limit of what can honestly be claimed.
Vitamin C is essential for making collagen. The enzymes that stabilise collagen need it to function, which is why prolonged severe deficiency produces the connective tissue failure known as scurvy. Collagen is in skin, blood vessel walls, gums, tendons, cartilage and bone, which is why deficiency shows up in so many places at once.
Here is the part that gets skipped. This relationship is a floor, not a dial. Below the requirement, things go wrong and correcting it fixes them. Above it, more does not produce more collagen. The enzymes are not waiting on extra supply.
The body also caps how much it absorbs. Past a few hundred milligrams, absorption efficiency drops sharply and the surplus is excreted. Which is why the article's own dosing advice was right: one or two capsules, not more.
About the antioxidant story
"Antioxidant" is the most overused word in this industry and the picture is genuinely more complicated than the marketing.
The straightforward version is that free radicals damage cells and antioxidants neutralise them. That is true as chemistry. What has not gone the way anyone expected is the next step: large trials of high-dose antioxidant supplements have generally failed to show the benefits the mechanism predicted, and a few have found the opposite of what was hoped.
Part of the explanation seems to be that some oxidative signalling is useful, including the signalling by which exercise makes you fitter, and flooding the system with antioxidants can blunt it.
None of which makes vitamin C pointless. It makes "rich in antioxidants" a much weaker recommendation than it sounds, and it is why this page no longer leads with it.
Grape seed extract, honestly
The OPCs in grape seed extract are well studied for blood vessel tone, and that is the area with the most consistent human data behind it.
We are not going to summarise those trials here, because this page sells the product and that is the line between explaining an ingredient and making a claim about a capsule. If it interests you, the literature is searchable and the compound name is oligomeric proanthocyanidins.
Who it makes sense for
Someone whose diet is short on fruit and vegetables, which is a large number of people and a genuinely good reason to take a vitamin C supplement. Someone who wants the grape seed extract specifically.
Not someone hoping it will do what the previous version of this page said.
It is vegan, gluten-free and halal, which is straightforwardly on the label. One or two capsules a day with food, and more than that will mostly upset your stomach.
If you are pregnant, nursing, or have any medical condition, ask a clinician first.
