Dirtea Reishi Mushroom Powder, for Calm, destress & Immunity, 1 Tin of Mushroom Powder, 60g, Containing 30 Servings

Full Spectrum Duanwood Reishi Mushroom (Dual Extraction) Extract Powder - Wild Cultivated (90g)

Free Shipping

Why We Love It

Dual extracted for potency.
Supports overall immune functions.
Free from additives and fillers.

Main Highlights

Our Duanwood Reishi Mushrooms are dual extracted using both alcohol and water. The two separate extractions are performed using temperature controlled, full spectrum extraction technology, before being gently dehydrated into an ultra fine micro-powder.
Potent 10:1 bio-active concentrated powdered extract. When our micro-powder is reconstituted in water, it is virtually identical to the original liquid extract. Extracting the active constituents of the reishi mushroom produces a bio-available & highly potent concentrate, which you simply add to any liquid to be taken daily as a powerful tonic.
Chemical constituents known as Reishi polysaccharides play an important role in supporting the body's overall immune functions. Reishi does not "stimulate" the immune system. It regulates it. And that is what makes Reishi so precious. Ganoderic acids promote proper oxygen utilization and support liver functions. Ganoderic acids are also antioxidant free-radical scavengers.
Absolutely free of any additives and fillers, synthetic ingredients, preservatives, flours and other bulking agents, gmo’s, dairy and gluten. Tested and certified pure from contamination of heavy metals, molds, chemicals and bacteria.
Packaged in amber glass jars in our organically certified premises. Na'vi is dedicated to sourcing the highest quality superfoods & tonic herbs from the most pristine areas of our planet.

NATURAL SUPPORT FOR RESTFUL SLEEP: Reishi is often regarded as the “wonder mushroom” for its ability to promote calm, support deep rest, and help the body unwind. Our pure, organic Reishi powder is rich in bioactive polysaccharides and makes an excellent addition to evening routines for those seeking a better night’s sleep and overall wellbeing.
CLARITY AND INNER BALANCE: Alongside Shilajit and Pine Pollen, Reishi is one of only 16 recognised adaptogens - plant-based substances known for helping the body maintain balance. It is often chosen to support focus and calm. Reishi is also appreciated for its skin-supporting properties, linked to its role in the body's natural detox processes.
10:1 CONCENTRATED EXTRACT FOR MAXIMUM POTENCY: Our Reishi extract powder is ten times stronger than raw mushroom, delivering a rich profile of beta glucans, terpenes, and antioxidants. The careful extraction method preserves the full spectrum of active compounds. Simply add to teas, coffees, smoothies, or foods for convenient daily use.
CERTIFIED ORGANIC, NATURAL AND VEGAN: Our Reishi powder contains no fillers, additives, or preservatives—just clean, concentrated mushroom extract. Each pouch provides up to 56 servings, offering excellent value and purity in every serving.
WOOD-GROWN FOR SUPERIOR QUALITY: Our Duanwood Reishi mushrooms are cultivated on natural wood in forest-like environments, allowing them to develop their full potency. We use only the mature fruiting body - never mycelium or grain substrate - ensuring you receive the highest quality, nutrient-dense Reishi available.
