How to Choose the Best Vitamin C Supplements
A common dose is around 1000 mg per serving, and some formulas add zinc or vitamin D for extra immune support. Choose a format you will take consistently, effervescent powders are easy and tasty (watch added sugar), while tablets and capsules are simple and sugar-free. Look for third-party testing and minimal unnecessary additives. Buffered or liposomal forms may be gentler on sensitive stomachs. Since vitamin C is water-soluble, your body excretes excess, but it is still wise to follow label guidance and consult your doctor.
Frequently Asked Questions
