Four Sigmatic's Immune Support Coffee With Vitamin D & Chaga Mushrooms is a new functional brew that pairs premium organic coffee with four immune-supporting ingredients. Branded as a "daily bodyguard" to support internal defenses, the coffee blend shares the benefits of Vitamin D, zinc, Turkey Tail and Chaga mushrooms. Notably, chaga was once used as a coffee substitute during World War II when beans weren’t available.
The Immune Support Coffee by Four Sigmatic itself is organic, fair trade and made from single-origin Arabica coffee beans. In terms of taste, the functional coffee blend is said to have notes of caramel and chocolate, plus one serving shares the benefits of 140% daily Vitamin D and 100% zinc.
