Magnesium glycinate

What hackers pick instead

• Creatine monohydrateA heavily studied, widely considered safe supplement that people credit with strength gains and sharper thinking, especially when sleep deprived; some report hair loss, stomach trouble or disrupted sleep.104recommend
• MelatoninRecommended for helping people fall asleep, often at low or liquid doses. Common caveat: morning grogginess, and evidence is weak outside jet lag and sleep disorders.43recommend
• N-acetylcysteine (NAC) supplementPeople recommend NAC as a cheap, generally safe supplement that they say helps with hangovers, brain fog, and stress, and that is widely studied. Critics say long-term safety data is limited and that it can worsen liver damage if taken after drinking.17recommend
• Psyllium huskA simple, cheap fiber supplement people use for hard stools and digestion. The main caveat is that it tastes and feels unpleasant.13recommend
• Magnesium L-threonatePeople recommend it for sleep and muscle tightness; critics say the brain benefit claims rest on a mouse study and the patent holder's research.9recommend
