Effervescent Vitamin C 1000 mg is a supplement used to add vitamin C to the diet. Vitamin C supports normal collagen formation and immune function, but this product does not prevent or cure infections.
Dissolve Effervescent Vitamin C 1000 mg fully in a glass of water, then drink it; do not chew or swallow the tablet whole. Follow the package directions and avoid taking more than the recommended amount.
Effervescent Vitamin C 1000 mg does not cure a cold or reliably prevent one. Regular vitamin C use may slightly shorten colds for some people, but starting it after symptoms begin usually has little effect.
No, Effervescent Vitamin C 1000 mg is not a replacement for fruit. It is an ultra-processed supplement that supplies vitamin C, while fruit also provides fiber and other nutrients; the two are not nutritionally interchangeable.
Yes, adults can take Effervescent Vitamin C 1000 mg daily, but this is more than most people need from a routine supplement. A higher dose does not provide extra protection, so consider whether you need a supplement at all.
It is better to dissolve Effervescent Vitamin C 1000 mg in cool or room-temperature water. Hot water is unnecessary and may affect vitamin C, which can break down with heat; let hot drinks cool before adding the tablet.
Effervescent Vitamin C 1000 mg does not cause kidney stones in everyone, but high supplemental doses may raise the risk in people prone to them. If you have had stones or have kidney disease, ask your doctor before using it.
No, Effervescent Vitamin C 1000 mg is not usually what makes urine bright yellow. That color is more commonly associated with riboflavin, or vitamin B2, in supplements; vitamin C can affect urine acidity instead.
Yes, Effervescent Vitamin C 1000 mg is not a stimulant, so taking it before bed does not usually disrupt sleep. If it gives you heartburn or an upset stomach, take it earlier and with food instead.
Effervescent Vitamin C 1000 mg is not automatically needed during pregnancy, and a high-dose supplement may duplicate vitamin C in a prenatal vitamin. Check the total amount in your supplements before adding another product.

Effervescent Vitamin C 1000 mg is a tablet supplement designed to dissolve in water, fizzing as it turns into a drink. Its flavour is usually tart and refreshing. It is commonly taken as a glass of water at breakfast or during the day; wait until the fizzing has settled before drinking.
This is a high-dose vitamin C supplement rather than a meaningful source of everyday food energy or protein. One tablet is about 3 g. Follow the directions on the pack, and use plain water unless the product instructions say otherwise. Its simple preparation can be convenient if you prefer a drink to swallowing a tablet.
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.
