Vitamin C also contributes to normal immune system function as recognised in EFSA-aligned guidance and NHS information.

Dr. Hemilä of University of Helsinki found that vitamin C supplementation may shorten cold duration in the general population, illustrating a potential immune-related benefit of this nutrient when consumed regularly as part of a balanced diet.
