Evidence supporting the use of: Vitamin A (retinol)
For the health condition: Injuries
Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Vitamin A (retinol) is scientifically recognized for its essential role in cellular growth and differentiation, including the maintenance and repair of epithelial tissues such as skin and mucous membranes. This underpins its use in supporting the healing of injuries, particularly wounds. Several animal and in vitro studies have demonstrated that Vitamin A can enhance epithelialization, increase collagen synthesis, and modulate inflammatory responses during the wound healing process. Clinical evidence in humans is more limited but does suggest a benefit, especially in individuals with Vitamin A deficiency or in cases of impaired wound healing, such as in patients undergoing corticosteroid therapy or those with chronic wounds.
However, evidence from large, high-quality randomized controlled trials in the general population is lacking. The most robust support exists for topical or systemic Vitamin A supplementation in specific cases of deficiency or delayed healing. Excessive supplementation in well-nourished individuals is not routinely recommended due to potential toxicity. Thus, while there is a scientific rationale for Vitamin A’s role in tissue repair, direct evidence for its routine use in treating injuries is moderate at best, justifying a low-to-moderate evidence rating.
