Beta-carotene is a pigment found in certain fruits and vegetables, acting as a precursor to vitamin A in the body. While it plays a crucial role in maintaining healthy vision and supporting the immune system, there is limited evidence to suggest that it has a significant impact on preventing or helping with Cough symptoms. Various medical studies have been conducted in recent years to investigate the potential benefits of Beta-carotene in respiratory conditions, including Cough but the results have been inconclusive.
One study conducted in 2002 assessed the effect of Beta-carotene supplementation on upper respiratory tract infections in a population of elderly individuals. The researchers found that there was no significant difference in the incidence or duration of Cough between the group receiving Beta-carotene supplements and the control group. Similar results were reported in a more recent review of randomized controlled trials evaluating the effectiveness of Beta-carotene in preventing respiratory conditions.
