Our Nattokinase Capsules deliver 5,000 FU per serving of nattokinase, a powerful enzyme extracted from natto, a traditional Japanese fermented soybean dish naturally rich in vitamin K2. However, during the extraction and purification process, most of the vitamin K2 is removed, leaving only trace amounts—if any at all. Since vitamin K or K2 is not listed on our supplement facts panel, any remaining content would be negligible.
If you're specifically looking to add vitamin K2 to your routine, you may want to check out our Liposomal Vitamin D3 + K2 for a highly bioavailable option: https://www.healthrangerstore.com/products/liposomal-vitamin-d3-k2-2-fl-oz-59-ml
