According to the World Health Organization, severe vitamin A deficiency affects hundreds of millions of children and pregnant women worldwide, with symptoms like night blindness often being an early indicator. When beginning supplementation, the timeline for observing improvements depends heavily on the severity of the deficiency, the form of vitamin A consumed, and an individual's overall health. While some effects like improved night vision can manifest relatively quickly, other benefits take longer to develop as the body replenishes its stored reserves.
