Vitamin C Tablets & Capsules

Guides and comparisons Multivitamins: how to compare daily vitamin & mineral formulas

Vitamin C tablets, capsules and chewables, mostly 500 mg or 1,000 mg per unit, in packs of 20 to 500 units, plus a few powders and liquids. Some contain bioflavonoids or rose hips, some are buffered, and others are timed-release or liposomal. Compare the milligrams of vitamin C per unit and the daily serving on the label: 100 % of the nutrient reference value (NRV) is 80 mg, so a 1,000 mg tablet shows as 1,250 % NRV. The ingredient list names the form of vitamin C and every added ingredient.

Frequently asked questions

What does buffered vitamin C mean?

Buffered vitamin C is usually a mineral salt of vitamin C, such as calcium ascorbate or sodium ascorbate, instead of plain ascorbic acid. The form is named in the ingredient list, and the amount of vitamin C per tablet or capsule is the figure in the nutrition table. Compare that amount, not the weight of the whole tablet.

What do timed-release and sustained-release mean on a vitamin C tablet?

These terms describe a tablet made to release its vitamin C gradually instead of all at once. They say how the tablet is made, and the nutrition table still states the amount of vitamin C per tablet. Compare that amount and the daily serving with those of a standard tablet.

What are bioflavonoids and rose hips on a vitamin C label?

Both are plant ingredients added alongside the vitamin C. Bioflavonoids are a group of plant compounds, and rose hips are the fruit of the rose plant, used as an extract or powder. The ingredient list names them, and some titles give the amount of bioflavonoids per tablet, such as 100 mg or 250 mg. Compare the vitamin C and the added ingredient separately.
