Drug intelligence / Profile preview
Vitamin A + zinc is a combination of two essential nutrients used for treating deficiencies and various health conditions. Vitamin A is important for retinal function, immune function, cellular communication, growth and development, and reproduction. Zinc is an essential trace element necessary for human health, growth, and sense of taste. The combination is available in both oral supplement form and topical ointment form. The topical formulation (Vitamins A & D-Zinc Oxide Ointment) is used as a moisturizer to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations such as diaper rash and skin burns. In clinical studies, the combination has shown efficacy in treating acne, with significant decreases in acne lesions after four weeks of treatment. However, some research indicates that the effect of zinc plus vitamin A was not better than zinc alone for acne treatment.
