Methodology
Randomised, double-blind, three-phase crossover trial of 56 g/day whey protein versus calcium caseinate and maltodextrin control for 8 weeks each.
Key Findings
24-hour ambulatory systolic blood pressure fell 3.9 mm Hg and diastolic 2.5 mm Hg with whey protein versus control, with improved endothelial function and lipid profile.
Conclusions
Chronic whey protein intake modestly lowers blood pressure and improves vascular and lipid markers in prehypertensive adults.
Limitations
High supplement dose not typical of habitual intake; single centre; dairy-tolerant participants only.
Supplements Studied
24-hour ambulatory systolic blood pressure fell 3.9 mm Hg with whey protein versus control.
