Nattokinase

Nattokinase is a protease enzyme produced by Bacillus subtilis var. natto, the bacterium used to ferment soybeans into natto, the traditional Japanese food from which the enzyme takes its name. Nustras supplies nattokinase as a fermentation-derived enzyme powder, standardised for enzyme activity, used mainly as an ingredient in dietary supplements.

Nattokinase is formulated into capsules, tablets and softgels, into powder blends with other enzymes or botanical ingredients, and into functional foods. Because it is a protein, formulators commonly choose protected delivery formats and avoid heat during processing.

Nattokinase is a fine, light-coloured powder. Its activity is expressed in fibrin-degradation units per gram and standardised to specification, confirmed by a fibrin-plate or equivalent activity assay; an enzyme has no single molecular formula. The fermentation medium is soy-based, so allergen status is stated on the specification. Heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies nattokinase in bulk commercial quantities, in sealed packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Nattokinase is an accepted supplement ingredient in major markets; buyers confirm the activity units, permitted daily amount and labelling for their application.
