Task: Answer Verification
Input (English): Question: Is melatonin more effective than ascorbic acid and β-carotene in improvement of gastric mucosal damage induced by intensive stress?
Answer: Melatonin is more effective than ascorbic acid and β-carotene in improvement of gastric damage induced by intensive stress. We suggest that as well as the direct antioxidant and free radical scavenging potency of melatonin, its indirect effect via the brain-gut axis might account for its greater beneficial action against stress-induced gastric damage.
Output (English): yes
