After consulting with immune system experts and rifling through hundreds of research studies...   We realized an important fact:  When it comes to overall well-being, the first part of the immune system that gets attacked by infections is our Respiratory System.  More specifically - the lungs.  That’s why BioFence was formulated with a “Respiratory-First” approach so that our body can stay strong against any harmful microorganisms.  This formula works so well in bolstering immunity because of these 3 clinically-researched Mushroom Extracts that possess immune support properties:  - Maitake Extract (Stimulates production of white blood cells to ward off infections.) - Reishi Extract (Strong antioxidant and contains triterpenes - which may help with allergies and support liver function. - Yunzhi Extract (Nourishes beneficial gut bacteria and supports gut health.)   Our customers shared that they’ve seen better results with Biofence’s mushroom-powered formula as compared to regular Vitamin C or multivitamins.   And it’s all thanks to these 3 natural mushroom extracts.
