Study, Trial or Testing Result Summary

Members OnlyHuman studies

This product lists a nattokinase complex at 135 milligrams a day, alongside a 1030 milligram proprietary blend whose contents and amounts are not shown. How much of the complex is actual nattokinase is unclear. No study in people has tested nattokinase for aging or cellular repair, and none of the studies measured biological age. All of the evidence comes from animals and cells. In mice and immune cells, nattokinase lowered inflammation, oxidative stress and clotting signals, and protected the kidneys from injury caused by a bacterial toxin [1]. In rats exposed to bisphenol A or radiation, it improved liver function, lowered oxidative stress and inflammation in the brain, eased memory-related chemical deficits, and reduced buildup of misfolded proteins [2]. In rats given nattokinase daily for seven days before an induced stroke, higher doses reduced brain damage, improved neurological symptoms, and lowered markers of inflammation, clotting and oxidative stress [3]. These results may not carry over to people, and the doses used in the animals could not be confirmed or compared with this product. Animal and cell studies are never counted.

Biohacker Summary

Members Only0 of 10 recommend it
0 of 10 biohackers on our panel recommend it

Nattokinase gets mostly favorable but mixed views from the panel: four of the nine who spoke recommend it, two use it, two are neutral, and one warns that the evidence is not convincing for heart or stroke prevention. People take it for healthy circulation and clotting, to clear arterial plaque, and to lower LDL cholesterol, and one panelist said a follow-up blood test showed it worked for him. Several stress high doses, citing 8,000 units or more, 10,000 units a day, or 12,000 up to 20,000 units, because low-dose products showed little effect in the data they cite, and one suggested taking it at night on an empty stomach or while fasting. Others use it to break up bacterial biofilms or to lower lipoprotein little a by 20 to 30 percent, and one prefers fermented soybeans (natto) over pills. Cautions include one panelist warning against taking it with meds, another doubting that an enzyme survives stomach acid, and a call for more trials to find the effective dose.
