Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Mineral ascorbates are buffered forms of vitamin C, such as sodium ascorbate or calcium ascorbate, which are often used as dietary supplements. The use of vitamin C to support convalescence (the recovery period after illness or surgery) is grounded in scientific rationale, though evidence is moderate. Vitamin C is an essential water-soluble nutrient with antioxidant properties, and it plays a key role in immune function, collagen synthesis, and wound healing—processes critical during recovery. Several clinical studies have shown that vitamin C supplementation can reduce the duration and severity of respiratory infections, and may improve wound healing post-surgery or injury. For example, a 2014 review in Nutrients noted that vitamin C deficiency impairs immunity and increases susceptibility to infections, which can prolong convalescence. Supplementation in deficient individuals may restore immune function and support recovery. Furthermore, vitamin C is required for collagen formation, which is necessary for tissue repair after injury or surgery. However, evidence is less robust in well-nourished individuals, and not all studies show a significant benefit for routine supplementation during convalescence. Mineral ascorbates are often preferred for their gentler effect on the stomach compared to ascorbic acid. In summary, while vitamin C (including mineral ascorbates) is scientifically justified for supporting recovery, especially in those with increased needs or deficiency, the overall strength of evidence for its widespread use in convalescence is moderate.
