What to Know Before You Start
Mushroom tinctures are widely celebrated for supporting focus, energy, immunity, and overall wellness. But like with any supplement, you might wonder: Can mushroom tinctures have side effects?
The good news? For most people, they’re extremely safe. But let’s walk through the rare cases, when to be cautious, and how to take them responsibly so you can feel confident starting your routine.
Are Mushroom Tincture Side Effects Common?
In short: no.Most people take functional mushroom tinctures daily without issue. However, everyone’s body is different and certain situations may increase the chance of sensitivity.
Possible (but rare) side effects include:
Mild digestive upset (especially if taken on an empty stomach)
Drowsiness or vivid dreams (typically from Reishi)
Increased energy or restlessness (usually from Cordyceps in sensitive individuals)
Mild allergic reactions (if you're sensitive to mushrooms or mold)
These effects are uncommon and usually mild—but it's worth knowing what to watch for.
Who Should Be Cautious with Mushroom Tinctures?
You should talk to a healthcare provider if you:
Are pregnant or breastfeeding
Have an autoimmune disorder (Reishi, Turkey Tail, and Shiitake may stimulate the immune system)
Take blood pressure, blood thinning, or immunosuppressant medications
Have a known mushroom allergy or sensitivity to fermented foods
At Boxed-In Mushroom Company, we use only the fruiting bodies, never grain-based mycelium—which is often where allergens and fillers creep in.
How to Reduce the Risk of Side Effects
If you're new to tinctures or want to be cautious, here are a few easy ways to get started:
Start Low and Slow
Begin with half a dropper (0.5 mL) once a day. Increase gradually if you feel good.
Take With Food
If you have a sensitive stomach, take your tincture after eating to reduce any digestive irritation.
Avoid Mixing With Hot Drinks
Heat can degrade active compounds—plus, combining with hot liquids may affect how your body reacts.
Stick to One at a Time
Trying multiple tinctures at once? Start with one, assess how you feel, then layer others in gradually.
The Bottom Line on Mushroom Tincture Side Effects
For the vast majority of people, mushroom tinctures are extremely well tolerated. When side effects do happen, they’re typically mild and temporary especially if you’re taking high-quality tinctures that are properly extracted and free from fillers or allergens.
