Is Four Sigmatic a good brand?
After all my weeks of testing, i recommend four sigmatic as an incredible mushroom coffee that will support your focus and daily productivity. It’s the best for coffee lovers who want the best for their health without compromising on taste. It tastes so good. Four sigmatic coffee is tested to ensure safety (in fact, the fda doesn’t actually have limits for naturally occurring lead, arsenic, cadmium, or mercury in coffee for adults). We test so so that our products contain: less than 0. Less than 5 ppm of arsenic.
