This delivers 167 mg of **Lactium** — a bioactive peptide derived from milk protein that binds GABA receptors to promote calm without the dependency risk of pharmaceutical options. At 167 mg, you're just above the 150 mg dose used in the key stress-reduction trial (63 women, 30 days), so one capsule daily puts you in the clinical range for stress support.

The evidence behind **Lactium** is early but directional — two small double-blind RCTs showed benefits for stress symptoms and sleep efficiency. A higher dose of 300 mg was used in the sleep study, so if your primary goal is sleep rather than daytime stress, you may want to double up to two capsules.

The main caveat is the thin research base. Both studies were small and funded by the ingredient manufacturer (Ingredia), and no meta-analysis exists yet. You're getting a clinically relevant dose, but the overall evidence level is limited — this is a reasonable option if you're exploring non-stimulant stress support, not a well-proven solution.
