Vitamin C is scientifically recognized for its critical role in collagen synthesis, which is essential for the maintenance and repair of connective tissues throughout the body, including those in the vocal cords (laryngeal tissues). Collagen forms a major structural component of the vocal folds, helping to preserve their elasticity and integrity. Several studies in both animals and humans have shown that vitamin C deficiency can lead to weakened connective tissues and impaired wound healing, which could theoretically compromise vocal cord function and recovery from strain or injury.

However, while vitamin C is well-established as necessary for general tissue health, direct scientific evidence specifically linking vitamin C supplementation to improved vocal cord health, prevention of vocal cord disorders, or enhanced vocal performance in healthy individuals is limited. The strongest support comes from its role in wound healing and reducing oxidative stress, which may indirectly benefit individuals experiencing vocal strain, inflammation, or recovery from vocal cord surgery. There is some anecdotal and limited clinical support for its use in managing hoarseness or laryngitis, but robust clinical trials are lacking. Overall, while vitamin C is physiologically important for the vocal cords, high-level evidence for supplementation beyond normal dietary intake specifically for vocal health is modest.
