Two mushrooms, one job each
- Natural gut and immune support. Turkey Tail's polysaccharides are immunomodulating: they help your immune system adapt to what it needs. And most of your immune system lives in your gut.
- A daily source of antioxidants. Chaga grows wild on birch trees in Northern Canada. It is used in herbal medicine to support the immune system, and it is a source of antioxidants.
- The easiest part of your morning. No capsules to remember, no powders to mix. A few drops in your coffee, tea, matcha or water, or straight under the tongue.
I noticed a significant difference in my overall wellness, mental clarity, focus, and immune support. It’s become a non-negotiable part of my daily routine!

Why it works as a pair
Two Rainbo tinctures, each doing its own job, in one daily ritual.
Turkey Tail is the immunity mushroom. Its polysaccharides are immunomodulating: they help your immune system adapt to what it needs. Ours is grown in Canada and dual extracted with water and ethanol. The ethanol is then taken out and glycerine goes in, so it is alcohol-free and lightly sweet. Chaga is the antioxidant mushroom. It grows wild on birch trees in Northern Canada and draws compounds like betulinic acid from the tree. Its black crust is melanin. Foragers take only part of each chaga, so it keeps growing. Then it is dual extracted: hot water for the polysaccharides, alcohol for the triterpenes. The whole ritual takes about a minute of your morning.

Questions before your first order
How do I take it?
4 mL of each, once or twice a day, with food. The dropper fills to 1 mL, so 4 mL is four fills. Add it to coffee, tea, matcha or water, or take it straight under the tongue. Both go in the same drink.
Why two mushrooms?
Each one does a different job. Turkey Tail is a source of fungal polysaccharides with immunomodulating properties. Chaga is a source of antioxidants and is used in herbal medicine to support the immune system.
What does it taste like?
Turkey Tail is glycerine-based, so it is lightly sweet and earthy; plenty of customers take it straight from the bottle. Chaga is earthy too, and in a coffee or a tea latte it disappears.
Is there an alcohol-free option?
Turkey Tail is always alcohol-free. Chaga comes alcohol-based, where the alcohol is the solvent that pulls out the triterpenes, or glycerine-based. Choose at checkout; alcohol-based is the default.
How long does a bottle last, and when will I notice it?
Each 100 mL bottle holds 25 servings of 4 mL. Immune support is a daily ritual, so give it a month: in our 2025 survey, 83% of daily takers who reported a benefit had been consistent for 30 days or more. Subscribe every 30, 60 or 90 days to match your pace.
Can I change or cancel my subscription?
Yes. Change the timing, skip or cancel any time. Shipping is free on every subscription order.
I'm pregnant, breastfeeding or on medication. Can I take it?
Ask your health care practitioner before you start. Both tinctures are for adults 18 and over.
