Review: Most needed enzyme ... - Serrapeptase is one of the most needed enzyme by the body . It's not a digestive enzyme , it's a systemic enzyme , it breaks down foreign protein build up in the body ..i am using it for my mast cell issue , which is triggered by sour and cold foods and gives me very bad headache ( piercing pain on the top or side of head, behind the eyeballs ) i am feeling some relief , i used it for one month only. Hoping to continue for atleast 3 months to see the effect. I have noticed more energy with it especially when i keep fasting for longer after eating it. It increases blood flow also so it can help with hair loss too. Review: good - good so far, been taking this supplement for only 2 months , i have allergic rhinitis and i don't sneeze that much now. ## Features - PROMOTES RESPIRATORY HEALTH: Doctor's Best High Potency Serrapeptase promotes and maintains healthy sinus and airway function and healthy immune response - OPTIMAL ABSORPTION: Serrapeptase can be destroyed by stomach acids if not properly protected.
