Can Nattokinase be used instead of Acard?

No, you can't. It is impossible to replace the drug with a dietary supplement. Nattokinase is a dietary supplement, it is not registered as a drug and does not have appropriate clinical studies confirming its effectiveness and safety. The possible interaction of Nattokinase with other medicinal products has also not been established. https://www.gdziepolek.pl/produkty/117019/swanson-nattokinaza-kapsulki/apteki Acard is an anticoagulant drug containing acetylsalicylic acid, which inhibits platelet aggregation (aggregation).
