Vitamin A Palmitate 15,000 IU promotes healthy vision. When our body is vitamin A-deficient, the eyes gradually lose their ability to adapt to light changes, resulting in "night blindness." Vitamin A also promotes skin and bone health. Preformed vitamin A is found in animal products such as meat, fish, poultry, and dairy foods. For those of us who don't get enough vitamin A in our diet, a supplement can be a great option.
