How to use Vitamin C TR

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger amounts, or for longer than recommended.

The recommended daily dose of vitamin C (ascorbic acid) changes with age. Follow your healthcare provider's instructions. You may also consult the Office of Dietary Supplements of the NIH, or the USDA Nutrient Database of recommended daily allowances for more information.

Drink plenty of liquids while you are using ascorbic acid.

You must chew the chewable tablet before you swallow it.

Do not crush, chew, or break an extended-release capsule. Swallow it whole.

Measure liquid medicine with the supplied measuring device (not a kitchen spoon).

Keep the orally disintegrating tablet in the package until you are ready to use it. Use dry hands to remove the tablet and place it in your mouth. Allow the orally disintegrating tablet to dissolve in your mouth without chewing.

Do not stop using ascorbic acid suddenly after long-term use at high doses, or you could have "conditional" vitamin C deficiency. Symptoms include bleeding gums, feeling very tired, and red or blue pinpoint spots around your hair follicles. Follow your doctor's instructions about tapering your dose. Conditional vitamin C deficiency can be difficult to correct without medical supervision.
