    Cellulose, serrateric, modified cellulose (vegetarian capsule).

    Good start

    Posted by iHerb Customer on Jan 14, 2018 | Verified Purchase

    I got it for my parents. My father 84 has problems with his sinuses for years. After taking it for a week his nose stopped running and no more sneezing. So far so good. My mom has arthritis and I really hope it will help. So far no change.

    Thanks for your feedback!

    Seems that it works

    I take 2 capsules , 2 or 3 times per day . I think it helps with sinus congestion and pain, it is different when I am not using it . I recommend it

    Thanks for your feedback!

    This product combined with Nattokinase is one of the best ways to improve blood health problems, speaking from experience of having bi lateral pulmonary embolisms 4 times over 7 years and having to use pharmaceutical drugs (warfarin) with side effects of bleeding gums, nose and bruising. Serrapeptase has helped in removing the clots and have kept my lungs clear for over a year.

    Thanks for your feedback!
