Frequently Asked Questions

That’s called a desiccant. It’s in there to absorb moisture and keep your capsules dry and potent for up to 2 years!
Yes, the bottle is recyclable. :)
In order to deliver effective benefits, the serving size is 3 capsules. This ensures you get ~1500mg of functional ingredients per serving.
Our recommendation is to take 3 capsules from one supplement at a time. After a few days to a few weeks, if you want additional benefits offered from another one of our capsules, you can begin to add in a full serving of that into your daily routine as well. Always check in with your healthcare practitioner if you have specific health concerns before taking any supplements, including Four Sigmatic Mushroom Complex Capsules.
