“I feel a greater sense of calm using this product. It’s easy to just add to my morning smoothie and enjoy. I also think that I have benefited from the immune support since my grandson has brought home the usual school viruses and I have succumbed to none of them. I am grateful for that!!”

What you see.
The fruiting body.
What you don’t.
The mycelium.
A scoop in your morning coffee, a smoothie, or yogurt.
Calm adds daily support for stress relief, longevity and immune health to the routine you already have.
Reishi builds with daily use. Consistency matters, most people notice benefits in weeks two to four.

From the label.
Quality doesn’t happen by chance. It’s built with intention and held through every step of the Om process. Every Om mushroom is organically grown and processed in our own BRCGS AA-rated, cGMP facility in California.
Our mushrooms are organically grown in our own clean rooms in California, on organic whole oats we prepare and inoculate with spores.
Harvested at peak maturity, then dried and milled in the same facility they were grown in.
Every harvest and product is tested in our own laboratory, then again by a third-party lab, for heavy metals and other contaminants.
It’s daily support, not a stimulant. Some people notice something the first day. Most describe a difference in the two-to-four-week window, and taking it every day matters more than any single serving.
One serving a day with a glass of water. The serving is on the label. Any time of day works, so pick one you’ll remember.
Calm is a single, focused addition for stress relief.
No. Calm is caffeine-free.
No. We don't use hot water or alcohol extraction. The whole mushroom, fruiting body and mycelium, is dried and milled into the powder inside each capsule.
At our own indoor farm in California, where we grow, dry and mill the mushrooms ourselves. They grow on organic, gluten-free whole oats. The mycelium feeds on the oats as it grows, and we harvest once it has worked through them.
Every product is tested in-house and by a third-party lab for heavy metals and other contaminants, and meets California’s Prop 65 standards. The mushroom powder is USDA certified organic, and every production lot is tested for gluten at 10 parts per million. The FDA’s line for a gluten-free label is 20.
