Antiviral Effects of Nattokinase

Inhibition of SARS-CoV-2 and Bovine Herpes Virus-1 Demonstrated in Vitro

Recently there has been intense focus on “natto” derived from the fermentation of steamed soy by bacillus subtilis. Nattokinase is a proteolytic enzyme used as an oral supplement by the Japanese for the chronic treatment of atherothrombotic cardiovascular disease. Now a recent study in the COVID-19 era by the Japanese demonstrated preventive antiviral effects against SARS-CoV-2 mutant strains and bovine herpes virus type 1. The mechanism appears to be proteolytic cleavage of viral proteins.

Oba and colleagues performed a series of experiments with various concentrations of nattokinase in preclinical models. They found: 1) nattokinase effectively stopped infection of human cells in culture from SARS-CoV-2 and bovine herpes virus type 1, 2) the proteolytic effect of nattokinase was heat sensitive.  (See link for article)



Besides having an ability to help “vaccine” injuries and prevent COVID and other viruses, Nattokinase and other proteolytic enzymes have been used by Lyme literate doctors (LLMD) for their role in breaking downbiofilm, the protective colonies many bacteria create which make them hard to eradicate.  Some use the zero-calorie sugar stevia for this purpose as well.

McCullough states that while it’s too early to make therapeutic claims, he says Nattokinase is the most promising data seen among all solutions to end the final state of the crisis: long COVID, “vaccine” injury, and recurrent infections.  For this reason don’t expect it to become mainstream!  This is precisely why they gave ivermectin and HCQ the death toll.  These, cheap, safe, effective drugs just do too many things that compete with the spin of Big Pharma, bought out government health agencies, and Big Media.
