AMT significantly improved mental clarity, focus, concentration, mood, and productivity at 60 and 120 min post ingestion, and the ability to tolerate stress at 60 min while also having significantly greater cognitive responses than LM and PL at 60 and 120 min post ingestion for mental clarity, focus, concentration, productivity, and perhaps mood (LM significantly improved subjective ratings of happiness compared to peers and “getting the most out of everything” at 60 min (from baseline) and maintained it at 120 min, whereas AMT significantly improved both of those ratings only at 120 min from baseline. However, AMT did have a significantly better rating of ‘happiness compared to peers’ than PL at 120 min post ingestion. On the other hand, PL may have improved the subjective rating of getting the most out of everything at 60 min from baseline. Overall, it appeared that LM had an influence on the happiness scale at 60 min, whereas AMT’s observances came to fruition at 120 min. Studies on LM’s impact on mood are limited, especially acute designs such as the current investigation, but one pilot study showed that
