Are you able to please advise the source of the Give Back Health NAC powder, and what fillers (if any) are used?

D: Most of the Give Back Health Clinic Collection compounding range products are 100% pure active ingredient, however the NAC does contain additional ingredients to help make the strong flavour more palatable to encourage compliance. The NAC that Give Back Health uses is a fermented NAC that is 100% vegan. Other ingredients in the formulation are natural orange flavour, natural sweetener (stevia), colloidal anhydrous silica and a very small amount of riboflavin for the orange colour.
