Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Seaweed, including various species such as kelp, wakame, and nori, has been investigated for its potential effects on hypertension (high blood pressure). Scientific studies suggest that regular consumption of seaweed may help lower blood pressure, primarily due to its rich content of bioactive compounds like peptides, polyphenols, and minerals (especially potassium, calcium, and magnesium). These components are known to influence vascular function and sodium balance, both important in blood pressure regulation.

Several animal and human studies have shown modest reductions in blood pressure associated with seaweed intake. For example, randomized controlled trials in humans have found that daily supplementation with seaweed extracts or consumption of seaweed as part of the diet can lead to slight but statistically significant decreases in systolic and diastolic blood pressure, particularly in individuals with prehypertension or mild hypertension. The mechanisms are thought to include inhibition of angiotensin-converting enzyme (ACE) by certain seaweed-derived peptides, as well as the antihypertensive effects of increased dietary potassium and reduced sodium absorption.

While the available evidence is promising, it is not yet robust or consistent enough to warrant strong clinical recommendations. Most studies are small, short-term, and use varying types and doses of seaweed. However, the use of seaweed for hypertension is supported by scientific rationale and preliminary evidence, meriting a moderate evidence score. Further large-scale, long-term trials are needed to clarify its efficacy and safety.
