Our daily requirement for vitamin C is higher than for any other water soluble vitamin. Ideally, vitamin C needs to be taken in small amounts throughout the day and night because it is rapidly lost from the body. These tablets are specially formulated to release the vitamin C gradually over 6-8 hours after swallowing, which means that the absorption of vitamin C into the bloodstream also occurs gradually. This is believed to create a more stable level of vitamin C in the blood for a longer period.
