FAQ
K2Life™ is a Vitamin K2 MK-7 ingredient manufactured in Taiwan, produced through precise and controlled deep fermentation of Bacillus subtilis var. natto, and standardized for Menaquinone-7 content to ensure specification stability.
Product features include a precision fermentation source, a highly stable long-chain MK-7 form, 100% natto ferment content meeting Clean Label requirements, and suitability for multiple dosage forms.
Yes, K2Life™ is derived from 100% natural natto ferment produced by Bacillus subtilis var. natto, without any artificial additives.
MK-7 is a long-chain form of Vitamin K2, which offers better chemical stability, formula tolerance, and higher bioavailability compared to MK-4.
K2Life™ has high formula tolerance and is suitable for diverse dosage forms including powders, capsules, tablets, sachets, and drinks.
K2Life™ is produced in Taiwan and complies with international quality management and manufacturing standards such as ISO 22000, HACCP, and GMP.
Because it is 100% fermented from natto without artificial additives, meeting the application requirements for single-ingredient Clean Labels.
It is recommended to store it in a cool, dry place, avoiding high temperatures, humidity, and exposure to direct light to maintain its activity and stability.
Through controlled deep fermentation technology, K2Life™ ensures high consistency in MK-7 content and purity across different batches.
MK-7 is considered to have superior intestinal absorption kinetics and blood concentration maintenance capabilities, with better bioavailability than Vitamin K1.
