Gelatin capsules in blister packs offer good shelter for this important vitamin, while liquid doses in glass bottles will also maintain viability.

Infants and children can require between 2,000 and 3,000 IUs, while adults ingest around 5,000 IUs daily. This can make supplementing with Vitamin A quite necessary, as deficiencies may lead to skin problems and a lowered immune response.

Vitamin A is one of the essentials, as it is only preformed within the body and requires outside sources to encourage full production and absorption through the small intestine. This vitamin is highly necessary for good eyesight, as it is responsible for the creation of rhodopsin, which allows for proper night vision. While this is often a reason for supplementing with Vitamin A, another important use is to aid healing and immune function.

This, combined with the attributes of promoting healthy cell growth, can keep all internal functions stay efficient. Between the effects on skin cells and internal tissues, Vitamin A is integral to maintaining youth and vitality.
