Overview

Doctor's Best sells this vitamin C as a vegan veg cap built on the Q-C ascorbic acid form. The bottle is meant for adult men and women who want immune support from a single nutrient.

A capsule is easier to dose than a powder, and the vegan, non-GMO, soy free and gluten free listing covers several dietary needs. The limitation is that a single nutrient does not replace a varied diet, and no serving size is given.

Who it's for

A person on a plant-based diet who takes vitamin C daily during the colder months. Anyone prone to kidney stones or on prescription drugs should check with a clinician before using a high strength.

Pros and cons

Pros
  • Vegan capsule, plant-based shell
  • Non-GMO, soy free and gluten free
  • Large capsule count
  • Single nutrient, simple label
Cons
  • Serving size not listed
  • Capsule only, no chewable
  • No added zinc or other nutrients

Performance notes

Vitamin C is water soluble, so the body removes what it does not use, and splitting a high daily amount across the day often suits it better than one large dose. Benefits relate to normal intake and do not prevent illness.
