A new study reveals that a common dietary supplement, often marketed for cognitive benefits, may not deliver the promised effects and could even pose risks under certain conditions. Researchers examined the supplement’s impact on brain function and found no significant improvements in memory or focus among participants, contradicting widespread claims. The findings also highlight potential interactions with medications, suggesting users should consult healthcare providers before use. Experts warn that the lack of regulation in the supplement industry allows misleading marketing to persist despite limited scientific backing.
