Nature Restore Organic Reishi Mushroom Powder
Reader ratings
A plain organic reishi fruiting-body powder, the cheapest we reviewed, with a heavy-metal report from Alkemist Labs. It is a whole-mushroom powder, not an extract, and no beta-glucan or microbe results are posted.
Best for Someone who wants reishi as an inexpensive powder to stir into coffee or cocoa, and accepts that it is unextracted and, for now, unmeasured for its active compounds.

How we evaluated it
Why we chose it What put it on our list
- The organic claim checks out. The USDA Organic Integrity Database lists Nature Restore Inc. (Brea, California) as certified by Organic Certifiers, Inc. since 2021-10-20, with Reishi Powder in its handling scope (record updated 2026-07-24).
- A real heavy-metal report is posted. Alkemist Labs (Garden Grove, California) tested lot NR2025006 by ICP-MS: arsenic 0.034, cadmium 0.087, mercury below 0.010 and lead 0.108 µg/g, 0.229 in total against a 10 µg/g limit printed on the report.
- It is one ingredient. The maker says fruiting body only, with no grain, mycelium or fillers, and that the label lists nothing else.
- At the maker’s 3 g serving it costs about $0.24, at $22.95 a jar, against about $0.89 for the dual-extract reishi we list.
Trade-offs What to weigh before you buy
- It is a plain milled powder, not an extract. Our reishi page recommends a dual extract: hot water for the polysaccharides and alcohol for the triterpenes. The maker says it tests “potency” but posts no beta-glucan or triterpene figure.
- The only report is for one lot from May 2025, and it covers heavy metals only. The maker says every batch is tested for heavy metals and potency; we found no microbe results.
- Lead and the serving size. A November 2025 Prop 65 notice named Nature Restore for lead in its greens powder (AG 2025-04551), settled in May 2026 with a warning required above 0.5 µg of lead per serving. Its cart drawer now shows a lead warning even when the cart is empty. The reishi lot’s 0.108 µg/g gives about 0.3 µg in a 3 g serving but about 0.65 µg in the 6 g serving Amazon describes, so check the serving size on your jar.
- Reishi may have an antiplatelet effect, so ask your doctor first if you take blood thinners, and rare case reports link powdered reishi to liver toxicity (see our reishi page). Human evidence is thin.
What to know Details worth knowing first
Nature Restore’s reishi is the simplest kind of mushroom product: organic reishi fruiting body, dried and milled, one ingredient. It is also the cheapest we reviewed, about $0.24 for a 3 g serving at the maker’s serving size.
What we could verify is limited but real. The USDA Organic Integrity Database lists Nature Restore Inc. as certified, with reishi powder in its scope. The maker links an Alkemist Labs report for one lot, with heavy-metal results by ICP-MS that sit far under the 10 µg/g limit printed on the report.
What we could not verify is what our checklist asks for most. This is an unextracted powder, and our reishi page recommends a dual extract. The maker says it tests “potency” but posts no beta-glucan or triterpene figure. The only report is for one 2025 lot and has no microbe results. If you buy it, treat it as a food-grade reishi powder, not a measured supplement. We are asking Nature Restore for beta-glucan and microbe results and for where the reishi is grown. For how the checks fit together, see how to tell if a supplement is pure.

What the labels mean

- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.

Alternatives Other options to compare
- Real Mushrooms Organic Reishi Extract Powder A dual extract with stated beta-glucan and triterpene minimums, approx. $40 for 45 g. Costs nearly four times as much per serving.
- Reishi made from mycelium on grain Often cheaper, but the label may not report starch, so “polysaccharides” can be mostly grain. See what to look for.
