Zipvit’s 1000mg vitamin C is one of the cheapest well-rated vitamin C tablets on Amazon UK: £8.99 for 180 tablets when I checked, which is 5p a day, with 4.6 stars from 2,305 ratings. The tub promises rosehip and bioflavonoids on top of the vitamin C. I wanted to know how much of that matters, and whether most people need a 1000mg tablet in the first place.
The short version
It’s a cheap, well-reviewed daily vitamin C, and at 5p a tablet the price is hard to argue with. The dose is far more than most people need: the NHS says adults need 40mg a day and should be able to get it from food. The rosehip and bioflavonoids are extras without stated amounts, so I’d treat them as marketing. The common complaint is the size of the tablet.
What’s in a tablet
| Vitamin C | 1000mg (as ascorbic acid) |
| Extras | Rosehip extract and citrus bioflavonoids, amounts not stated in the listing text |
| Other ingredients | Magnesium stearate (flow agent), hydroxypropyl methylcellulose and glycerin (coating) |
| Dose | One tablet a day |
| Pack | 180 tablets (six months); Zipvit also sells 360 |
| Diet | Vegan, gluten-free, non-GMO according to the listing |
Vitamin C is the cheap part of almost any supplement, so what you’re really paying for is the tablet, the brand and the convenience. I haven’t seen good evidence that adding bioflavonoids or rosehip changes how well the vitamin C is absorbed, and Zipvit doesn’t say how much of either is in a tablet.
Do you need 1000mg?
Probably not. The NHS page on vitamin C says adults aged 19 to 64 need 40mg a day, and that a varied diet should cover it. It also says that taking less than 1,000mg a day from supplements is unlikely to cause any harm, while more than 1,000mg can cause stomach pain, diarrhoea and wind. One of these tablets sits right at that line, so don’t stack it with an effervescent vitamin C or a high-dose multivitamin.
Where a supplement makes sense is a diet that’s short on fruit and vegetables, or simply wanting a cheap insurance tablet. For that, 1000mg is more than you need, but at 5p it isn’t a costly mistake.
What owners say
Amazon’s summary of the reviews (October 2026) counts 52 positive and 12 negative mentions of value, and 40 positive out of 46 mentions of effectiveness, although it’s hard to judge what a vitamin does from a review. The split is over swallowing: 53 reviews mention it, some say the tablets are quite large and hard to swallow whole, and others find the bullet shape easy enough. Taste comes up too: some reviewers find it pleasant and others very sour.
The cons
- The tablets are big. If you struggle with large tablets, a chewable or effervescent vitamin C will be easier.
- 1000mg is 25 times the NHS’s daily figure, and the tablet can’t easily be split into a smaller dose.
- The rosehip and bioflavonoids have no stated amounts.
- The same tub is listed twice on Amazon UK at different prices (£8.99 and £9.99 when I checked), so check which listing you’re on.
- The label advises speaking to your GP first if you’re pregnant, breastfeeding, taking medication or under medical supervision.
How to take it
One tablet a day, with a drink. Taking it with a meal is the easiest way to remember it, and some people find vitamin C kinder on the stomach with food. If you already take a multivitamin, check how much vitamin C it contains before adding this.
Price per tablet vs alternatives (Amazon UK, 21 Oct 2026)
| Product | Dose | Pack | Price | Per tablet | Amazon rating |
|---|---|---|---|---|---|
| Zipvit Vitamin C with Rosehip & Bioflavonoids | 1000mg | 180 | £8.99 | 5.0p | 4.6 (2,305) |
| Lindens Vitamin C+ Time Release | 1000mg | 360 | £16.00 | 4.4p | 4.7 (2,510) |
| Nutravita Vitamin C | 1000mg | 180 | £9.99 | 5.6p | 4.6 (15,327) |
| New Leaf Vitamin C | 1000mg | 120 | £7.94 | 6.6p | 4.6 (872) |
| Vitabiotics Ultra Vitamin C (slow release) | 500mg | 60 | £3.59 | 6.0p | 4.6 (5,995) |
Prices are approximate and change daily; the live price is the one on Amazon. Zipvit’s own site sells the 360-tablet pack for £16.99, about 4.7p a tablet. Our vitamin C price table compares 23 options and is re-checked regularly.
All of these are cheap, and the difference between them is a few pence a week. Lindens’ 360-tablet tub is the lowest price per tablet. If you want a smaller dose, Vitabiotics’ 500mg slow-release tablet costs about the same per tablet and stays well under the NHS’s 1,000mg line.

FAQ
Is 1000mg of vitamin C a day too much?
The NHS says supplements under 1,000mg a day are unlikely to cause harm, and more than that can cause stomach pain and diarrhoea. One 1000mg tablet is at that line, so don’t combine it with other high-dose vitamin C products.
Are Zipvit vitamin C tablets vegan?
Yes, the listing describes them as vegan, gluten-free and non-GMO.
Do the bioflavonoids help absorption?
I haven’t seen good evidence that they do, and Zipvit doesn’t state the amount per tablet.
How long does a tub last?
At one tablet a day, 180 tablets last six months and the 360 pack a year.
Can I split the tablet?
The listing doesn’t say the tablets are scored for splitting. If you want a lower dose, a 500mg tablet is the simpler choice.
Verdict
As a cheap daily vitamin C, Zipvit’s tablet is good value and well reviewed, and the large tablet size is the only complaint that comes up often. Most people don’t need 1000mg, and the rosehip and bioflavonoids are extras I wouldn’t pay more for. On paper I’d rate it 7/10, and I’ll update that once I’ve used a tub myself.
