How to read this chart. Every brand prints a different kind of number. Rainbo's [3,000mg] is a dried-mushroom equivalent: between 188mg and 375mg of concentrated fruiting-body extract, depending on how the three extracts are split ([8:1] Lion's Mane, [16:1] Reishi, [8:1] Cordyceps), standing in for 3,000mg of dried mushroom. The other brands on this chart print the weight of mushroom powder in the cup, or an extract weight, with no extraction ratio. Each row shows what that brand's own label says. Where a brand gives no ratio we count its figure as 1:1 dried mushroom when we call ours the highest on the chart, which is the most generous reading for that brand. Prices are regular retail on the brand's own site on 2026-09-04, before promotions; a brand that sells only in US dollars is shown in US dollars, not converted. We will correct any row a brand tells us is wrong: info@rainbo.com.
MUD/WTR's own panel describes its blend as mushrooms and mycelium cultured on organic oats and/or organic sorghum; the panel does not say how much of the listed weight is mushroom. Landish lists mushroom fruiting bodies and mycelia. Organic Traditions prints an extract figure with no ratio. Fungki is made with 100% organic fruiting body mushrooms.

Why Is This Important?
Functional mushrooms are traditionally taken daily.
The human studies below used a set daily amount for weeks, which is why we print ours. Here are three human studies on the mushrooms in Fungki - Lion's Mane, Reishi, and Cordyceps, with the amounts they used.
1. Reishi · the physical work capacity study
In a 30-day randomized, double-blind study, female college students who took 1,000mg of Reishi daily improved physical work capacity and grip strength.
Fungki's Reishi is part of its [3,000mg] dried-mushroom equivalent per cup, from a [16:1] fruiting-body extract.
2. Lion's Mane · the same-day focus study
In a randomized, double-blind, placebo-controlled crossover study, healthy adults took 1g of a Lion's Mane extract and were tested the same day. Lion's Mane supported working memory and reaction time.
Fungki's Lion's Mane is part of its [3,000mg] dried-mushroom equivalent per cup, from an [8:1] fruiting-body extract.
Go deeper: La Monica et al., 2023 · Nutrients. Lion's Mane also has a 16-week cognition study in older adults: Mori et al., 2009 · Phytotherapy Research
3. Cordyceps · the energy and stamina study
In a 12-week double-blind study, healthy adults aged 50 to 75 who took about 1,000mg a day of a Cordyceps preparation (Cs-4, a cultured Cordyceps sinensis mycelium product) raised the point at which their bodies begin to tire. Fungki's Cordyceps is a Cordyceps militaris fruiting-body extract, a different preparation.
Fungki's Cordyceps is part of its [3,000mg] dried-mushroom equivalent per cup, from an [8:1] fruiting-body extract.
Each study used a set daily amount for weeks. That is why every cup of Fungki carries a [3,000mg] dried-mushroom equivalent of Lion's Mane, Reishi and Cordyceps, printed with its extract ratios ([8:1], [16:1], [8:1]), at the lowest price per gram on this chart at regular prices.

Rainbo's Fungki vs. The Biggest Competitor
Some mushroom powders are mycelium grown on grain, and the grain travels into the powder. MUD/WTR's own panel describes its blend as mushrooms and mycelium cultured on organic oats and/or organic sorghum, and does not say how much of the listed weight is mushroom. Landish lists fruiting bodies and mycelia together. Fungki uses fruiting body only and prints its extraction ratios. Fruiting-body advocates, Rainbo among them, hold that hericenones and triterpenoids concentrate in the fruiting body rather than in a grain substrate. We formulate on that basis.
Fungki is made with 100% organic, dual-extracted fruiting-body mushroom extracts. Our mushroom extracts come with a certificate of analysis for their active compounds (beta-glucans, triterpenes, cordycepin), and finished batches are third-party tested for heavy metals, pesticides and mycotoxins. Certificates available on request.
