I recall the big splash that came with the marketing of ZMA as a supplement[1] for testosterone production quite a while ago. It was something OTC that I tried on several occasions and found to have limited merit. Unlike some other products, I didn't feel the ZMA effects in muscles per se, but noticed significantly deeper (better?) sleep and recovery. If ZMA was assisting in recovery and sleep more than anything, then I could definitely buy into the notion magnesium has quite a few physical and mental upsides as a supplement (with further research!).
