If the exposure is over a prolonged period and there’s a change in appearance, it may mean that the contents of the tablets have been affected, or they may have been contaminated or may have even turned mouldy. If that is the case, you should discard them.

Due to the nature of the ingredients, the tablet form offers the most stable and compact way of delivering the ingredients. As most of the ingredients are water-soluble, having to produce these tablets in a soft capsule form will result in the creation of a huge capsule (which makes for difficult swallowing). This is because there will be the need to add oil, which serves as a binding agent.
