納豆激酶 Nattokinase × 高血壓
The evidence base for nattokinase lowering blood pressure is small, internally inconsistent, and not endorsed by any major body.
The evidence base for nattokinase lowering blood pressure is small, internally inconsistent, and not endorsed by any major body. A 2023 meta-analysis pooling only 6 RCTs (546 participants) reports a modest, statistically significant reduction (SBP about -3.45 mmHg, DBP about -2.32 mmHg), and two small short trials (2008 South Korea n=86, 2016 North America n=79) show a directionally similar effect. However, the largest and longest trial (NAPS 2021, n=265, median 3 years) found no significant blood-pressure effect, directly contradicting the shorter trials, and individual studies are mostly n<90, heavily East-Asian, with funding largely undisclosed and manufacturer conflict of interest unexcludable. Examine grades Blood Pressure C on a single n=86 study; no health authority (FDA, EFSA, NHS, WHO, TFDA) authorises a blood-pressure claim, and neither the AHA nor any hypertension society addresses or endorses it. A modest signal with a contradicting pivotal trial and no authoritative support is a textbook C: limited, suggestive evidence that is not strong enough for B and not absent or refuted enough for D.

台灣社群（PTT regimen/Health_Life、Mobile01 健康養生版）對納豆激酶（多以『納豆紅麴』複方出現）有實質第一手討論：心血管/三高保養是長輩族群常見話題，部分使用者自述血液循環改善、手腳較不冰冷、半年後血壓血脂回正；但 Mobile01 同時有強烈反方聲音，質疑市售品為人工發酵、誇大『天然食品』而忽視出血風險，並主張經醫師開立的阿斯匹靈更便宜安全。整體反應分歧偏謹慎，且納豆紅麴是業配重災區（mybest/嚴萃等排行榜、仿 PTT 內容農場灌水嚴重）。
分歧——PTT regimen 有正面實測（自述血液循環改善、手腳較不冰冷、半年後血壓血脂回正、『三高狀況減輕了許多』），但多為納豆紅麴複方且常合併飲食運動調整，難歸功單一成分；Mobile01 則有反方主張市售品誇大、效果不如醫師開立的阿斯匹靈，亦有人『吃了無什麼感覺』

- 降血壓過度致噁心、頭暈（低血壓者不宜，媒體與社群皆提醒）
