Magnesium for Sleep? 12 Trials Say the Hype Outruns the Evidence
Magnesium is marketed as a natural sleep aid, but a new systematic review of 12 randomized controlled trials in adults says the evidence doesn't support it as a routine insomnia treatment. Results were inconsistent across questionnaires, EEG, actigraphy and wearables, and certainty was low to very low. The review used narrative synthesis rather than a meta-analysis because the trials differed so much in forms, doses and populations. Some adults may still see modest subjective benefits, particularly those with low intake. Here's what the paper found, what it didn't, and how to approach a magnesium trial sensibly.
400 mg of Chamomile Extract Improved Sleep in 4 Weeks, and the Effect Lasted
Chamomile tea is the classic wind-down drink. Apigenin, one of chamomile's best-known compounds, has become a staple of "sleep stacks" in biohacking circles. A 2017 randomized trial in Complementary Therapies in Medicine tested a more concentrated version of the idea. It gave older adults 400 mg of chamomile extract a day for four weeks and tracked their sleep quality afterward.
