Hi All, If this is OK for us this is a great deal. It's only $5 a bottle for 50 capsules compared to the Biotech which is $18 for 100. I've used some of Nature's Life's other products and they seem fine. Good reviews, too. https://www.swansonvitamins.com/nat...W9vFcUE5KEQm9tYMFMcFgl58VJR-24fwaAus4EALw_wcB Apparenly, Phytomenadione (Biotech) is the same as phylloquinone (Nature's life): https://en.wikipedia.org/wiki/Phytomenadione Thoughts?
