Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Lactalbumin, a major protein component of whey, has been studied for its potential to support stress management. The scientific interest is based on its high content of tryptophan, an amino acid precursor to serotonin—a neurotransmitter involved in mood regulation and stress resilience. Several clinical studies have explored the impact of alpha-lactalbumin-enriched diets on stress and mood. For example, a notable randomized controlled trial in American Journal of Clinical Nutrition (2002) found that subjects consuming alpha-lactalbumin exhibited increased plasma tryptophan levels and improved cognitive performance under stress, particularly in individuals with high trait anxiety. Subsequent studies have shown similar trends, suggesting modest anxiolytic and mood-stabilizing effects, though the overall effect size is small and may depend on individual differences in baseline anxiety or stress vulnerability.
Despite these findings, the evidence base is limited and not universally conclusive. Most studies are small and short-term, and not all trials have found significant clinical benefits. There is some mechanistic plausibility, but alpha-lactalbumin’s use for stress management remains a subject of ongoing research rather than an established intervention. Its use is not rooted in traditional medicine, but rather in modern nutritional neuroscience. Thus, while there is scientific validation, the strength of evidence supporting lactalbumin for stress is moderate at best.
