NOW Foods Nattokinase, 100 mg, 120 Veg Capsules

NOW Foods Nattokinase is a single-ingredient supplement designed to support cardiovascular and circulatory health, derived from the traditional Japanese fermented soy food natto. Each 100 mg capsule provides 2,000 Fibrinolytic Units (FUs) of enzyme activity, a standardized measure of potency that aligns with common dosing in this category.

This product uses nattokinase sourced from non-GMO soy, and the manufacturer notes that clinical and non-clinical studies have been conducted on nattokinase for circulatory support. It is formulated as a vegan capsule, with other ingredients like microcrystalline cellulose and vegetable-based stearic acid, and is produced in a GMP-certified facility in the USA. Available in a 120-capsule size, it also comes in a 60-capsule variant, and carries certifications such as Vegan and Kosher that are notable for plant-based supplements.
