Mineral ascorbate refers to a buffered form of vitamin C, typically combined with minerals such as sodium, calcium, or magnesium. Vitamin C has been studied for its potential role in respiratory allergies, including allergic rhinitis and asthma. The rationale lies in vitamin C's antioxidant properties and its capacity to modulate immune function. Some small clinical trials and observational studies suggest that vitamin C supplementation may reduce the severity of respiratory allergy symptoms, possibly by reducing histamine levels and oxidative stress in airway tissues.

However, the quality and consistency of the evidence remain low. Most studies involve small sample sizes, variable dosing regimens, and short durations. Systematic reviews have concluded that while there is some indication of benefit, the evidence is not strong enough to recommend vitamin C (including mineral ascorbate forms) as a primary or sole treatment for respiratory allergies. It is sometimes used as an adjunct alongside standard therapies, but not as a replacement for established treatments like antihistamines or corticosteroids.

In summary, while there is some scientific basis and preliminary evidence supporting the use of mineral ascorbate in respiratory allergies, the overall strength of evidence is weak (rated at 2/5). More rigorous, large-scale clinical trials are needed to confirm efficacy and to establish clear guidelines for use.
