Function?

Vitamin A is crucial for maintaining healthy vision, particularly in low-light conditions. It contributes to the production of visual pigments in the eyes. Vitamin A supports the immune system by helping maintain the health of skin and mucous membranes, which act as barriers against infections and is involved in the growth and development of cells, aiding in the regulation of cell growth and specialization.

Whole food sources of vitamin A?

Grass-fed beef liver, dark leafy greens, pasture-raised eggs, carrots, and yams are all good sources of vitamin A.
