Nature Restore Organic Reishi Mushroom Powder

1. What is in it 25% of the rating 4 of 5

   One ingredient, organic reishi fruiting body, and nothing else. It is a whole-mushroom powder, not an extract, and states no beta-glucan.

2. Independent testing 35% of the rating 2 of 5

   Two heavy-metal reports for one lot (Alkemist 2025, Harken 2026), both ordered by the maker, and the second reads lead 44% higher. No beta-glucan, microbe or independent result.

3. Evidence 15% of the rating 2 of 5

   Reishi’s human evidence is one small uncontrolled trial, and our page recommends an extract, not a plain powder. The 3 g serving is near the trial doses, but the claims on the label (“adaptogenic”) run ahead of it.

4. Trust 10% of the rating 3 of 5

   A 2025 Prop 65 lead notice on another Nature Restore product (settled 2026), a lead warning in its cart, a serving of 3 g on its label but 6 g in Amazon’s text, and a 50% first-order affiliate commission. No recall or warning letter.

5. Value 15% of the rating 5 of 5

   About $0.24 a 3 g serving and $0.08 a gram, the cheapest here by far. It is not an extract, so a gram holds much less of the active compounds.

The rating, 3.1 of 5, is the weighted average of these scores. See how we rank mushroom supplements and our standard.

Nature Restore had a lead notice. Is this one safe?

A Prop 65 notice (opens in a new tab) filed 7 November 2025 named Nature Restore for lead in its American Grown Greens Powder, and it settled on 20 May 2026 with warnings required above 0.5 µg of lead per serving. Its site still shows a lead warning in the cart for every order. The one reishi lot we can see reads 0.108 µg/g lead at Alkemist (about 0.32 µg per 3 g) and 0.156 µg/g at Harken Research (0.47 µg per 3 g, as its report prints it): both under 0.5 µg, though not by much on the second, and both from the same 2025 lot.

Is a serving 3 g or 6 g?

The label says 3 g and about 94 servings: in the maker’s label image, on its product page, in the Supplement Facts image in Amazon’s gallery and in Walmart’s text. Amazon’s text for the same jar says a tablespoon is roughly 6 g and the jar holds about 47 servings, and another Amazon image says about 141. We read label images, not a jar in hand. At 3 g the lead is 0.32 to 0.47 µg; at 6 g it would be 0.65 to 0.94 µg, over the 0.5 µg level. Weigh a serving instead of counting scoops, and take the amount your jar’s label gives.

Is a plain powder as good as an extract?

Not in the way our pages recommend. Our reishi page points to a dual extract, and our turkey tail page says hot-water extraction frees beta-glucans from the mushroom’s chitin-rich cell walls. The maker posts no beta-glucan or triterpene figure, so we cannot say how much of either a serving holds.

Who is paid to promote it?

Nature Restore’s affiliate page (opens in a new tab) offers 50% commission on a referred customer’s first order and 8% on later orders, with no cap. A commission that high gives promoters a strong reason to praise it, so weigh online reviews with that in mind.

Has anyone independent tested it?

No. The only results we found are the maker’s own: the Alkemist report and a Harken Research report for the same lot. ConsumerLab’s 2026 reishi review tested seven other products, not this one.

• 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).
• One ingredient and nothing else: the label reads organic reishi powder (Ganoderma lucidum, fruiting body) 3 g, and “other ingredients: none”. No grain, mycelium or fillers.
• Two heavy-metal reports are posted for the same lot, from two labs. 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. Harken Research (Pasadena, California) tested the finished jar of the same lot in April 2026: lead 0.156, cadmium 0.102, arsenic not detected, mercury below quantitation.
• 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.

• It is a plain milled powder, not an extract. Our reishi page recommends a dual extract, and our turkey tail page says hot-water extraction is what frees beta-glucans from the cell walls. The maker says it tests “potency” but posts no beta-glucan or triterpene figure.
• Both reports are for one lot, NR2025006, and cover heavy metals only, with no microbe results. The maker ordered both, so they are its own tests, and the second lab read lead 44% higher than the first. We found no report for a later lot.
• Lead and the serving size. A November 2025 Prop 65 notice named Nature Restore for lead in its greens powder, settled in May 2026 with a warning required above 0.5 µg of lead per serving. Its cart drawer still shows a lead warning. At the 3 g serving the label shows, the reishi lot comes to 0.32 µg by Alkemist’s figure and 0.47 µg by Harken’s, under 0.5 µg but only just on the second. At the 6 g serving Amazon’s text describes it would be 0.65 to 0.94 µg. Weigh your serving.
• 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.

• Real Mushrooms Organic Reishi Extract Powder A dual extract with stated beta-glucan and triterpenoid figures, approx. $40 for 45 g. Costs nearly four times as much per serving, and posts SGS Canada reports the maker ordered (beta-glucan 30.5% and low metals in the 45 g pouch).
• 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.
