Zinc is often overlooked in sleep discussions, but research increasingly links this mineral to sleep depth, REM quality, and nighttime recovery.
Zinc’s Role in Sleep Regulation
Zinc is required for the conversion of 5-HTP to serotonin and melatonin synthesis. Without adequate zinc, your body struggles to produce enough melatonin.
REM Sleep Enhancement
A 2017 study found that zinc supplementation increased REM sleep duration by 18% in zinc-deficient adults. Low zinc correlates with fragmented sleep architecture.
The Zinc-Magnesium Connection
Zinc and magnesium share transporters in the gut. Taking them together in a 1:2 ratio optimizes absorption of both. Many ZMA formulas exploit this synergy.
Dosing and Timing
Take 15-30mg zinc glycinate or picolinate with dinner. Avoid zinc oxide. Exceeding 40mg daily long-term can deplete copper stores.
