    1. Hi Rosa,

      Note that the active ingredient (ingredient which brings about the benefit of the supplement) is Vitamin C.

      The rest of the ingredients in the list are what we call excipients. All supplements have them, as their function is to hold everything together so it remains as a solid tablet form for you to consume.

    1. Thank you for your question Zara. Note that any supplements or medication which is prolonged released / modified released should be swallowed whole and not chewed. This is because most of the time it is the coating which is responsible for the prolonged release. Hope this helps!
