Hypotension (Low blood pressure)
Supplements studied for hypotension (low blood pressure).
Overview
Two supplements are indexed for hypotension (6 studies). Caffeine has the stronger profile (medium effect size, high evidence, very high trust, WA 72; 3 studies). It may help certain low-blood-pressure situations—such as neurogenic orthostatic hypotension or post-meal drops in some elderly patients—but trials are small and context-specific.
Green Tea (WA 48; low effect size, medium evidence, medium trust; 3 studies) has uncertain benefit; one small study found pre-meal green tea raised post-meal blood pressure in elderly patients with postprandial hypotension, though overall evidence is limited.
