Tight deadlines. Back-to-back meetings. Long nights and early mornings. We all push a little too hard sometimes, which comes at a cost. Running in high gear for too long can lead to breakdown, including prolonged inflammation that compromises immunity and makes us susceptible to minor and major illnesses. Chaga is a fungus that grows on the back of birch trees in cold climates. It promotes the formation of beneficial cytokines — proteins that regulate the immune system — and stimulates white blood cells that fight harmful bacteria and viruses. Chaga unleashes powerful antioxidants to fight inflammation, promote recovery, reduce blood sugar levels, and improve insulin resistance.
