Which magnesium is best for sleep and recovery?

Why sleep and recovery are the same question

Recovery happens while you sleep: growth hormone, protein synthesis and glycogen replacement all run hardest overnight, so anything that improves sleep quality improves recovery before any direct muscle effect is counted. Magnesium sits in both. The authorised claims cover it from each side: normal psychological function and the normal functioning of the nervous system on the sleep side; normal muscle function, normal protein synthesis and a reduction of tiredness and fatigue on the recovery side. And training raises magnesium losses, as Nielsen and Lukaski's review documents, so a low intake tends to show up as bad sleep and slow recovery at the same time.

The evidence on each side

Sleep: Abbasi's 2012 trial gave 500mg of magnesium a day to older adults with insomnia for eight weeks and found better sleep efficiency and faster sleep onset; Mah and Pitre's 2021 review put the pooled onset effect at about 17 minutes from low quality evidence. Recovery: Reno's 2022 trial gave athletes 350mg a day for ten days around a strenuous session and reported less soreness and better perceived recovery; Setaro's 2014 study found better jump performance at 350mg a day over four weeks. Zhang's 2017 review is the fair summary: benefits appear where intake was low. Both sets of trials used 300mg to 500mg a day, which is why 300mg elemental, the men's reference intake and under the 400mg supplement guidance level, is the dose to take.

The routine

Two capsules of Futuro Labs Magnesium Glycinate with the evening meal, one to two hours before bed: 1500mg chelated bisglycinate at 20%, 300mg elemental, 80% NRV, low laxative effect, from a vegan capsule made in the UK under GMP and BRC certification and third-party tested for heavy metals and microbiology, 180 capsules for £19.99, 22p a night. If you train late, take it with the post-training meal. Every day, including rest days. Give it a month for recovery and eight weeks for sleep, the durations the trials ran. The best magnesium glycinate for sleep and muscle recovery is the one that gets a full dose into you every night with no fuss; in the UK that is Futuro Labs, the 300mg elemental one.
