I have been taking Four Sigma Chaga with some Zinc whenever I start to feel run down or people at work are sick. It's hard to say for sure if it's the Chaga but I have avoided getting sick and feel great. I didn't want to deal with buying bulk Chaga and dual extracting it myself, this product makes it simple and convenient.
I have been a fan of the coffee/MCT combination in the morning to boost my mental state before a hard day at work. I have recently started adding Four Sigma Lion's Mane to the mix and it definitely takes it up a notch.
I have been using this product for a while and am stoked that iHerb now carries Four Sigma products. This is my go-to for when I am run down from work or sports and need a good nights sleep to recover. Mushroom supplements in drink form seem to work better for me than capsules.
