Can You Take Erythorbic Acid with Vitamin C?

Research shows that taking Erythorbic Acid and Vitamin C together does not cause any significant interactions. Erythorbic Acid, a stereoisomer of Vitamin C, has less than 5% of Vitamin C's biological activity. Studies in guinea pigs found that Erythorbic Acid does not affect Vitamin C's absorption or catabolism. No mechanism of interaction was identified between Erythorbic Acid and Vitamin C. Erythorbic Acid has a different spatial configuration than Vitamin C, which results in lower biological activity. This difference in configuration may contribute to the lack of interaction between the two compounds.
