What option of non-acidic vitamin C, would be better for infections?: Gentle C, Ester C or Ascorbic Acid?

R/ With the exception of the original form of vitamin C (ascorbic acid), all other options are valid. Gentle C provides calcium, so the choice depends on other needs. If calcium intake is preferred then the Gentle C is the best option. Any of the other two are useful and you may adjust the dose.
