glycine vs magnesium glycinate for sleep
Glycine and magnesium glycinate are two different supplements that support sleep through different mechanisms: glycine is an amino acid that lowers core body temperature and acts as a calming neurotransmitter, while magnesium glycinate delivers well-absorbed magnesium that supports muscle and nerve relaxation. Evidence for glycine improving sleep quality is strong at around 3 g before bed, while magnesium is most effective for people with low magnesium intake. This guide compares both head to head, explains whether you can combine them, and helps you decide which fits your situation.
