What goes into every jar
Eight functional mushrooms, a handful of supporting ingredients, and nothing you can't pronounce. Here's each one, and why it's there.
The detail most brands skip.
A mushroom has two main parts: the fruiting body (the mushroom you'd recognize) and the mycelium (its root-like network). Many low-cost supplements use mycelium grown on oats or rice — and the grain gets ground up with it, so the final powder can be mostly starch.
Every mushroom in FurHealth is a fruiting body or a fruiting-body extract. It costs more, but you get real mushroom in every scoop.
