“ Calcium ascorbate has been developed to mitigate the gastric irritation caused by the acidity of ascorbic acid.”
“The area under the curve (AUC) values of calcium ascorbate were 1.5-fold higher than those of ascorbic acid , and the Cmax value of calcium ascorbate (91.0 ng/ml) was higher than that of ascorbic acid (74.8 ng/ml).”
“Thus, although calcium ascorbate showed equivalent antioxidant activity to ascorbic acid, it could attenuate the gastric high acidity caused by ascorbic acid , making it suitable for consideration of use to improve the side effects of ascorbic acid.”
