What Are Effervescent Vitamin C 1000mg Tablets?
Vitamin C — also known as ascorbic acid — is one of the most widely recognised nutrients in the body. It plays a central role in immune function, skin health, and the formation of collagen. Most people get some vitamin C through their diet, but there are times when a supplement can help fill the gap. Effervescent vitamin C 1000mg tablets offer a convenient, easy-to-take format that dissolves in water, making them a popular choice for adults who struggle with standard capsules or tablets. You can browse the full range of options in our vitamins and supplements collection.
Valupak Effervescent Vitamin C 1000mg Tablets come in a pack of 20 and are available for just £2.29 — making them one of the most accessible ways to top up your daily vitamin C intake. Each tablet delivers a full 1000mg dose of ascorbic acid, which is well above the UK recommended daily intake of 40mg but within the range commonly used for supplementation.
How Do Valupak Effervescent Vitamin C Tablets Work?
Ascorbic acid is a water-soluble vitamin, which means the body cannot store it in the way it does fat-soluble vitamins. It needs to be replenished regularly through food or supplementation. Once dissolved and ingested, vitamin C is absorbed in the small intestine and distributed to tissues throughout the body. Here is how it works:
- Acts as an antioxidant, helping to protect cells from oxidative stress caused by free radicals
- Supports the biosynthesis of collagen, a structural protein essential for skin, cartilage, and wound healing
- Contributes to normal immune system function, particularly during and after periods of physical stress
- Enhances the absorption of non-haem iron from plant-based foods when taken alongside iron-rich meals
- Supports normal energy-yielding metabolism and reduces tiredness and fatigue
The effervescent format means the tablet is pre-dissolved before you drink it, which can make it gentler on the stomach compared to swallowing a large tablet whole.
Who Should Use Valupak Effervescent Vitamin C 1000mg Tablets?
These tablets are suitable for most healthy adults who want to support their daily vitamin C intake. They are particularly useful during winter months, periods of illness, or times of increased physical demand. That said, they are not appropriate for everyone.
- Adults aged 18 and over looking to supplement their daily vitamin C intake
- People who find standard tablets or capsules difficult to swallow
- Those with a diet low in fresh fruit and vegetables
- Individuals recovering from illness or surgery who want to support immune function and tissue repair
They are not recommended for children without specific medical advice, and people with certain health conditions — including kidney stones or haemochromatosis — should speak to a healthcare professional before use.
How Do Valupak Effervescent Tablets Compare to Standard Vitamin C Tablets?

| Dose per tablet | 1000mg | Typically 500mg–1000mg |
| Format | Dissolves in water | Swallowed whole |
| Ease of use | Suitable for those who dislike swallowing tablets | Convenient but requires swallowing |
| Palatability | Flavoured drink format | Unflavoured or coated |
How Should You Store Valupak Effervescent Vitamin C Tablets?
Store these tablets in a cool, dry place below 25°C, away from direct sunlight and moisture. Keep them out of reach of children at all times. Do not use after the expiry date printed on the packaging. If you are looking for other health products to support your wellbeing, our cold and flu range includes a variety of options that complement vitamin C supplementation during the winter months.

Specifications of Valupak Effervescent Vitamin C 1000mg Tablets 20's
What Is Valupak Effervescent Vitamin C 1000mg and What Is It Used For?
Valupak Effervescent Vitamin C 1000mg Tablets contain ascorbic acid as the active ingredient. Ascorbic acid is a form of vitamin C — an essential nutrient that the human body cannot produce on its own. It must be obtained through diet or supplementation. These tablets are used to supplement dietary vitamin C intake and to support normal immune function, collagen formation, and the reduction of tiredness and fatigue. They are also used to support iron absorption from plant-based foods.
Vitamin C deficiency, though uncommon in the UK, can lead to symptoms such as fatigue, irritability, and in severe cases, scurvy. Supplementation at 1000mg per day is commonly used during periods of increased need, such as illness, recovery, or high physical activity.
What Do You Need to Know Before Using Valupak Effervescent Vitamin C 1000mg Tablets?
Before taking these tablets, read the following carefully. Do not take them if any of the contraindications below apply to you without first speaking to a healthcare professional.
Do not take if you:
- Have a history of kidney stones (nephrolithiasis), particularly oxalate stones
- Have haemochromatosis (iron overload disorder)
- Have glucose-6-phosphate dehydrogenase (G6PD) deficiency
- Have hyperoxaluria
- Are allergic to ascorbic acid or any other ingredient in the tablet
Warnings and precautions:
- Pregnant or breastfeeding women should not exceed 1000mg per day and should consult a GP or midwife before use
- High doses of vitamin C may interfere with certain laboratory tests, including blood glucose and urine tests
- Do not take alongside other high-dose vitamin C supplements to avoid exceeding safe intake levels
Known drug interactions — tell your pharmacist if you are taking:
- Aluminium-containing antacids (vitamin C increases aluminium absorption)
- Warfarin or other anticoagulants (high-dose vitamin C may affect INR)
- Iron supplements (vitamin C significantly increases iron absorption — this may be beneficial or problematic depending on your condition)
- Aspirin or non-steroidal anti-inflammatory drugs (NSAIDs), which may reduce vitamin C levels
- Certain chemotherapy agents — always consult your oncologist before taking supplements
How Should You Use Valupak Effervescent Vitamin C 1000mg Tablets?
Always follow the directions on the packaging. Do not exceed the stated dose. Here is how to take them correctly:
- Fill a glass with at least 200ml of cold or room-temperature water
- Drop one effervescent tablet into the glass
- Wait for the tablet to fully dissolve — this usually takes 1–2 minutes
- Stir gently if needed, then drink the solution immediately
- Do not swallow the tablet whole or allow it to dissolve in your mouth
| Indication | Age Group | Dose | Frequency |
|---|---|---|---|
| Dietary supplementation | Adults 18+ | 1 tablet (1000mg) | Once daily |
| Children under 18 | Under 18 | Not recommended without medical advice | — |
What Are the Possible Side Effects of Valupak Effervescent Vitamin C 1000mg Tablets?
Like all supplements, vitamin C can cause side effects, particularly at higher doses. Most people tolerate 1000mg per day well, but it is worth knowing what to look out for. If you are also managing other health concerns, you may find our indigestion range helpful if gastrointestinal discomfort occurs.
Common side effects (may affect some users at 1000mg/day):
- Stomach discomfort or cramps
- Nausea
- Diarrhoea (more likely if dose is exceeded)
- Heartburn or acid reflux
Less common side effects:
- Headache
- Flushing of the skin
- Kidney stones with prolonged high-dose use in susceptible individuals
- Interference with blood glucose monitoring results
If you experience any severe or unexpected reaction, stop taking the tablets and seek medical advice promptly.
How Should You Store Valupak Effervescent Vitamin C 1000mg Tablets?
- Store below 25°C in a cool, dry place
- Keep away from direct sunlight and moisture — effervescent tablets are particularly sensitive to humidity
- Keep the tube or packaging tightly closed after each use
- Keep out of sight and reach of children
- Do not use after the expiry date printed on the packaging
- Do not store in a bathroom cabinet or near a sink

Frequently Asked Questions
Where can I buy Valupak Effervescent Vitamin C 1000mg Tablets online in the UK?
You can buy Valupak Effervescent Vitamin C 1000mg Tablets directly from Cured Pharmacy for just £2.29 per pack of 20 tablets — no prescription required. They are available as a General Sale List (GSL) product, meaning they can be purchased without visiting a GP or pharmacist in person. Browse our full vitamins and supplements collection for more options.
How do effervescent vitamin C 1000mg tablets work in the body?
Ascorbic acid is absorbed in the small intestine and carried to tissues throughout the body, where it functions as an antioxidant and supports collagen production. Because vitamin C is water-soluble, the body does not store it — any excess is excreted in urine, which is why regular daily intake matters. The effervescent format delivers the dose in liquid form, which may be easier on the stomach for some people.
How do I use Valupak Effervescent Vitamin C 1000mg Tablets step by step?
Drop one tablet into a glass of at least 200ml of water and allow it to fully dissolve before drinking — this usually takes around one to two minutes. Do not swallow the tablet whole or chew it, as it is designed specifically to be dissolved first. Take one tablet per day, ideally at the same time each day to build a consistent routine.
What is the recommended daily dose of Valupak Effervescent Vitamin C 1000mg Tablets?
The recommended dose is one tablet (1000mg) dissolved in water, taken once daily for adults aged 18 and over. You should not take more than one tablet per day unless specifically advised to do so by a healthcare professional. Exceeding the recommended dose increases the risk of gastrointestinal side effects such as diarrhoea and stomach cramps.
What is the best time of day to take Valupak Effervescent Vitamin C 1000mg Tablets?
There is no single "best" time to take vitamin C, but taking it with or after a meal can help reduce the chance of stomach discomfort. Some people prefer to take it in the morning as part of their daily routine, while others find it convenient to take with lunch. Consistency matters more than timing — try to take it at the same time each day.
What are the side effects of Valupak Effervescent Vitamin C 1000mg Tablets?
At the recommended dose of 1000mg per day, most people tolerate these tablets well. However, some individuals may experience stomach discomfort, nausea, heartburn, or diarrhoea — particularly if taken on an empty stomach. If side effects are troublesome, try taking the tablet with food or speak to your pharmacist about whether a lower-dose supplement might be more suitable.
Who should not take Valupak Effervescent Vitamin C 1000mg Tablets?
These tablets are not suitable for people with a history of kidney stones, haemochromatosis, glucose-6-phosphate dehydrogenase (G6PD) deficiency, or hyperoxaluria. Children under 18 should not take them without specific medical advice. Pregnant or breastfeeding women should consult their GP or midwife before starting any high-dose vitamin C supplement.
Can I take Valupak Effervescent Vitamin C 1000mg Tablets with other medicines?
Vitamin C at 1000mg per day can interact with certain medicines, including aluminium-containing antacids, warfarin, and iron supplements. If you are taking any prescribed medicines or other supplements, speak to your pharmacist before starting these tablets. This is especially important if you are on anticoagulant therapy or undergoing cancer treatment.
What happens if I miss a dose of Valupak Effervescent Vitamin C 1000mg Tablets?
If you forget to take your daily tablet, take it as soon as you remember — provided it is still the same day. If you only remember the following day, skip the missed dose entirely and continue with your usual schedule. Never take two tablets in one day to compensate for a missed dose.
How long can you take Valupak Effervescent Vitamin C 1000mg Tablets for?
Vitamin C supplements can generally be taken on an ongoing basis at the recommended dose, as they are water-soluble and excess is excreted rather than accumulated. However, if you are taking 1000mg daily for an extended period, it is sensible to review this with your GP or pharmacist periodically. For short-term immune support during illness or recovery, a course of a few weeks is typically sufficient.
Are Valupak Effervescent Vitamin C 1000mg Tablets suitable for vegetarians or vegans?
Ascorbic acid itself is suitable for vegetarians and vegans, but you should check the full ingredient list on the product packaging to confirm that all excipients (inactive ingredients) in the effervescent tablet are also free from animal-derived components. If you are looking for verified vegan health products, our vegan collection may be helpful.
Do Valupak Effervescent Vitamin C 1000mg Tablets help with colds?
The evidence on vitamin C and the common cold is nuanced. Regular supplementation does not appear to prevent colds in the general population, but it may modestly reduce the duration and severity of symptoms in some people, particularly those under significant physical stress. The NHS notes that vitamin C contributes to normal immune function, which is why many people choose to supplement during winter months.
What are the alternatives to Valupak Effervescent Vitamin C 1000mg Tablets?
Alternatives include standard vitamin C tablets or capsules at lower doses (such as 500mg), chewable vitamin C tablets, or dietary sources such as citrus fruits, kiwi, peppers, and broccoli. If you prefer a non-effervescent supplement or a different dose, browse our vitamins and supplements collection for a range of formats. Always choose the format that best suits your lifestyle and tolerance.
Can Valupak Effervescent Vitamin C 1000mg Tablets help with skin health?
Vitamin C plays a key role in collagen synthesis, which is essential for maintaining skin structure, elasticity, and wound healing. Supplementing with vitamin C may support skin health, particularly in people with low dietary intake. For topical skin support, you might also explore our skin care collection alongside your supplement routine.
What is the latest research on high-dose vitamin C supplementation?
Research continues to explore the role of vitamin C in immune modulation, antioxidant defence, and collagen production. Current evidence supports its role in reducing fatigue and supporting normal immune function at supplemental doses. The NHS and BNF both recognise ascorbic acid as an established treatment for vitamin C deficiency and as a safe supplement at doses up to 1000mg per day for most healthy adults.
