Study
Taking Daiwa Brain Health supplements for 90 days improved memory scores in older adults, compared to Prevagen.
In plain language
A recent study explored how two supplements, Daiwa Brain Health and Prevagen, affect memory in older adults. Participants who took Daiwa Brain Health, which contains Hokkaido scallop oil, showed significant improvements in memory tests over 90 days. In contrast, those who took Prevagen did not experience such improvements. This finding suggests that Daiwa Brain Health could be more effective in supporting memory and cognitive health. For seniors concerned about maintaining brain health, this study highlights a potential supplement to discuss with healthcare providers.
