A vitamin C tablet (1000 mg) is a high-dose supplement used to increase vitamin C intake. Vitamin C supports normal immune function and collagen formation, but taking a tablet does not replace a varied diet or treat an illness.
It may slightly shorten a cold for some people who take vitamin C regularly, but it does not reliably prevent colds or cure one once symptoms begin. A vitamin C tablet (1000 mg) is not a substitute for medical care when symptoms are severe.
Yes, many healthy adults take a vitamin C tablet (1000 mg) daily, although this dose is more than most people need if their diet already supplies enough. Count vitamin C from other supplements too, and follow the product directions.
You can take a vitamin C tablet (1000 mg) with or without food. If it causes nausea, heartburn, or stomach discomfort, taking it with a meal or just afterward may make it easier to tolerate.
Common side effects of a vitamin C tablet (1000 mg) can include nausea, stomach cramps, and diarrhea. These digestive effects are more likely at higher intakes; if they persist, stop taking the supplement and seek medical advice.
High vitamin C intake may increase urinary oxalate and contribute to kidney stone risk in some people. Anyone with a history of kidney stones or kidney disease should be particularly cautious about taking a vitamin C tablet (1000 mg) regularly.
There is no established best time to take a vitamin C tablet (1000 mg). Choose a time you can stick to; if it bothers your stomach, take it with food rather than right before bed.
No, a vitamin C tablet (1000 mg) cannot guarantee protection from infections. Vitamin C is needed for normal immune function, but taking extra vitamin C does not reliably stop you from catching a cold or other common illnesses.
Yes, vitamin C can improve absorption of iron from plant foods, so taking a vitamin C tablet (1000 mg) with an iron-containing meal may help. If you use an iron supplement, ask a health professional whether combining them suits you.
Yes, high-dose vitamin C can affect some treatments or interfere with certain laboratory test results. If you take prescription medicines, especially as part of cancer treatment, ask your doctor or pharmacist before using a vitamin C tablet (1000 mg).

A Vitamin C tablet (1000mg) is a supplement that provides vitamin C in a compact, measured form, rather than a food eaten for its flavour or as part of a meal. Depending on the product, it is swallowed with water or dissolved first; follow the directions on its packaging.
Swallowable tablets may taste mildly chalky, while effervescent versions tend to make a tangy drink. It is not nutritionally comparable to a typical snack: a serving is about 4 g, and the notable feature is its 1000 mg of vitamin C. If you already take supplements or are unsure whether this amount suits you, check with a pharmacist or other health professional.
Very high
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Low
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
