Starting with the Verified Label
Before examining what each species does, one fact about Micro Ingredients’ Mega Mushroom Powder needs to be established clearly: the Supplement Facts panel lists a single entry — a 1g proprietary blend — with no per-species amounts disclosed. Everything written in this breakdown is based on what each species is known to contribute as a compound class, not on a guaranteed per-serving amount for this specific product. The dose math is outlined in the full Micro Ingredients review.
One additional note: some versions of this product’s marketing copy reference vitamins (B Complex, C, D) and minerals (Zinc, Calcium, Magnesium). None of these appear on the verified Supplement Facts panel. This breakdown addresses only what the label confirms.
With that established, here is what each of the ten organic species in this blend is known for.†
Lion’s Mane — Hericium erinaceus
Lion’s Mane is the most researched species in this blend for cognitive applications. It contains two compound classes — hericenones (found in the fruiting body) and erinacines (found in the mycelium) — that have been studied for their relationship to nerve growth factor (NGF) synthesis.† NGF plays a role in the growth and maintenance of neurons. Human research has examined Lion’s Mane for cognitive function and memory support, with studies typically using 500mg to 3,000mg of extract daily. At a blended serving of approximately 100mg per species, this product delivers a fraction of studied doses. Lion’s Mane’s inclusion is nonetheless meaningful as a daily-habit contribution to a broader mushroom routine.†
Chaga — Inonotus obliquus
Chaga is a parasitic fungus that grows primarily on birch trees in cold climates. It is among the most antioxidant-dense functional mushrooms, with a high ORAC value attributed to its melanin content and betulinic acid derived from its birch tree host. Research has examined Chaga’s polysaccharide content in the context of immune modulation.† It is not a true mushroom in the culinary sense — it produces no visible fruiting body cap — and is typically harvested as a sclerotium (hardened mycelial mass). Its inclusion in blends is primarily for its polyphenol and polysaccharide contribution.†
Reishi — Ganoderma lucidum
Reishi is the most widely used adaptogenic mushroom in East Asian traditional medicine, with a history spanning several thousand years. Its bioactive profile includes polysaccharides (beta-glucans), triterpenes (ganoderic acids), and sterols. Triterpenes in particular are associated with Reishi’s bitter taste and are studied for their relationship to immune regulation and stress response.† Published research has used Reishi in ranges from 1,000mg to 5,000mg daily. As a daily-habit blend component it contributes to a broad adaptogenic foundation alongside the other species.†
Turkey Tail — Trametes versicolor
Turkey Tail is among the most clinically studied functional mushrooms globally. Two polysaccharide complexes isolated from Turkey Tail — Polysaccharide-K (PSK) and Polysaccharide-Peptide (PSP) — have been studied extensively in the context of immune support.† PSK in particular has been researched in Japan for decades and holds a regulatory status in that market as an immunological adjunct. Turkey Tail’s inclusion in any multi-mushroom blend is a positive signal for immune-focused positioning.†
Cordyceps — Ophiocordyceps sinensis
Wild Cordyceps sinensis is one of the most expensive functional mushrooms in the world, harvested from high-altitude regions of the Tibetan Plateau. The cultivated form used in supplements (typically Cordyceps militaris or a sinensis equivalent grown on substrate) provides cordycepin, a compound structurally similar to adenosine that is researched in the context of energy metabolism and cellular ATP production.† Research has used Cordyceps in the range of 1,000mg to 3,000mg daily for performance and fatigue applications. Its inclusion in this blend contributes to the energy-adjacent positioning of the formula.†
Wood Ear Mushroom — Auricularia auricula-judae
Wood Ear is both a culinary mushroom (widely used in East Asian cooking) and a functional species with a polysaccharide profile that includes beta-glucans associated with immune and cardiovascular support research.† It is less frequently discussed in Western supplement contexts than Lion’s Mane or Reishi but has a meaningful research base in Asian scientific literature. Its inclusion diversifies the polysaccharide contribution of this blend.†
Oyster Mushroom — Pleurotus ostreatus
Oyster mushrooms are among the highest beta-glucan-containing mushroom species in their dried powder form, with some analyses measuring beta-glucan content in the range of 25% to 30% of dry weight. This makes Oyster mushroom a meaningful beta-glucan contributor in a blend even at lower doses.† Research has examined Oyster mushroom in the context of immune function and lipid metabolism. It is also one of the most widely cultivated edible mushrooms globally, contributing to consistent supply reliability in certified organic blends.†
Shiitake — Lentinula edodes
Shiitake is the best-known culinary functional mushroom in the world. Its primary bioactive compound is lentinan, a beta-1,3-glucan with a documented research history in immune modulation.† Lentinan has been studied in clinical settings in Japan for decades. Shiitake also contains eritadenine, a compound studied for cholesterol metabolism, and a full amino acid profile. As a dual culinary-functional species, its inclusion supports both the nutritional and adaptogenic positioning of a multi-species blend.†
Maitake — Grifola frondosa
Maitake, known as “hen of the woods” in North America, contains a distinctive polysaccharide called D-fraction, which has been studied for immune-modulating effects.† Research has examined Maitake in the context of immune cell activity and metabolic support. It is one of three mushroom species — alongside Reishi and Shiitake — studied together for synergistic immune effects in published macrophage research. Its combination with Turkey Tail, Reishi, and Shiitake in this blend covers the most clinically supported immune-modulating species available in supplement form.†
Mesima — Phellinus linteus
Mesima is the least familiar species in this blend to Western buyers. It is a bracket fungus with a history of use in Korean and Japanese traditional medicine. Research has examined its polysaccharide content, particularly hispolon and other phenolic compounds, in the context of immune and antioxidant applications.† It is a less common inclusion in Western multi-mushroom blends, and its presence here represents a broader approach to species diversity than the standard five- or six-species formulas. Per-species research on Mesima is more limited than for Lion’s Mane, Reishi, or Turkey Tail, which is worth noting for buyers who weight research depth heavily.†
What the “Other Ingredients: None” Line Confirms
The Supplement Facts panel for this product lists no other ingredients. No binders, fillers, flow agents, maltodextrin, rice flour, silica, or excipients. The powder is composed entirely of the ten mushroom species listed. For a multi-species powder at this price point, a genuinely empty Other Ingredients line is notable. Many products at similar price points include flow agents or carrier powders that dilute the mushroom content per gram.
The Bottom Line on Ingredients
Micro Ingredients’ formula covers the most researched functional mushroom species across immune, cognitive, and adaptogenic categories, combined with less common species (Wood Ear, Mesima) that broaden polysaccharide diversity. All ten are certified organic. No fillers are present. The limitation is dose depth: at 1g total across ten species, this is a breadth-first blend, not a high-dose single-target formula. Both approaches have a role in a well-considered supplement routine; they are just different tools.†
