Chlorella for Blood Pressure Regulation

Research suggests that chlorella may support blood pressure regulation through multiple biological pathways, including modulation of nitric oxide production, antioxidant activity, and anti-inflammatory signaling, all of which can influence vascular function. The available evidence reviewed in a 2026 narrative review indicates a generally favorable direction for chlorella's effects on blood pressure outcomes, with proposed mechanisms involving endothelial function and reduction of oxidative stress in blood vessel walls. However, the current evidence base is limited, as the summarized findings derive from a single review article rather than a body of independent randomized controlled trials or meta-analyses specifically targeting blood pressure as a primary outcome. Readers should be aware that more rigorous, large-scale clinical trials are needed before strong conclusions can be drawn about the reliability or magnitude of any blood pressure effects.
