Best sleep and recovery supplements for men
Around 90% of your daily testosterone is produced during deep sleep. Even one night of four hours reduces testosterone by 10-15%. These supplements do not replace good sleep hygiene, but they remove the nutritional deficiencies that prevent deep sleep from happening.

Adam's quick picks
What the evidence says
A 2012 RCT in the Journal of Research in Medical Sciences found magnesium supplementation improved sleep quality, onset time, and early morning cortisol in elderly men with insomnia. L-theanine (200mg) increased alpha brain wave activity and subjective sleep quality in a 2019 Nutrients study.

Read article →Frequently asked questions
What is the best form of magnesium for sleep?
Magnesium bisglycinate (also called glycinate) has the best absorption and is gentlest on the gut. Avoid magnesium oxide - it absorbs at roughly 4% and acts primarily as a laxative. Transdermal magnesium spray is an effective alternative for those who get digestive issues from oral forms.
Does melatonin work for sleep?
Melatonin helps with sleep onset (falling asleep faster) but does not improve deep sleep quality. The effective dose is 0.5mg, not 5mg - higher doses do not increase efficacy and increase grogginess the next morning. Best used for shift work and jet lag rather than nightly.
Can supplements fix poor sleep?
No. Address the foundations first: consistent wake time, no screens for 90 minutes before bed, cold dark room, no alcohol. Supplements work on the margins. Magnesium and L-theanine are most useful for men who have good sleep habits but still feel their sleep quality is insufficient.
