Why Lactium for Stress & Mood
Lactium plays a supporting role in stress & mood. Bioactive decapeptide (alpha-casozepine) derived from bovine alpha-s1 casein via tryptic hydrolysis. Binds GABA-A receptors with benzodiazepine-like anxiolytic action without dependence risk.
What dose to look for
Clinical studies typically use 150–300 mg of lactium. RCTs used 150–300 mg/day. Kim 2007 used 150 mg/day for stress; Kim 2019 used 300 mg/day for sleep. Products below this range may not deliver meaningful results.
What the research says
Lactium has limited clinical evidence for stress & mood benefits. Only 2 small manufacturer-funded clinical trials (48-63 participants each) for stress and sleep Learn more
Clinical research on Lactium (Alpha-S1 Casein Hydrolysate)
LOW — Small RCTs, no meta-analysis, manufacturer involvement · 150–300 mg/day
- •Kim 2007 DB-RCT (63 women, 150 mg/day, 30 days, crossover): reduced stress symptoms across digestive (p<0.01), cardiovascular (p<0.05), intellectual (p<0.01), emotional (p<0.05), and social (p<0.05) domains.
- •Messaoudi 2005 DB-RCT (healthy volunteers, 200 mg acute ×3 doses): significant cortisol reduction under combined stress tests (p<0.05) and lower blood pressure changes vs placebo.
- •CERTAIN 2022 (100 acne patients, 150 mg/day, 12 weeks): cortisol −4.75 µg/dL (p<0.001), PSS and HAM-A improved (p<0.001). However, open-label design substantially weakens findings.
- •Mechanism: contains alpha-casozepine, a decapeptide from bovine alpha-s1 casein that binds GABA-A receptors with benzodiazepine-like anxiolytic action without dependence risk. No meta-analysis exists; most studies involve manufacturer Ingredia.
