Both supplements have a real but modest literature behind them. For magnesium L-threonate specifically: a randomized trial (n=100, 6 weeks, 2g/day) found improved cognition and a better subjective sleep-impairment score, but no objective difference on a wearable ring; another trial (n=80, 21 days, 1g/day) did find objective improvement in deep and REM sleep. For chamomile/apigenin: a meta-analysis (10 trials, 772 participants) found a significant reduction in sleep-quality score (PSQI), while one isolated pilot trial (n=34) found no difference on primary outcomes. Overall it leans toward a real but modest benefit, clearer for people who already sleep poorly than for good sleepers — consistent with the corpus's own note on magnesium ("not a universal sleep fix").
