Walk into any health food store or scroll through Instagram, and you'll find them everywhere: mushroom powders promising enhanced immunity, laser focus, and boundless energy. Promises, sold in powders, pills, and dried packets. Lion's mane for your brain. Reishi for stress. Chaga for longevity. The functional mushroom market has exploded, with companies selling these products as the ultimate wellness hack.
There's just one problem: most of these products don't work the way you think they do.
We’re not saying mushrooms don't have health benefits; research shows they do. However, here's what the glossy marketing doesn't mention: if you're just stirring raw mushroom powder into your morning coffee, you're likely flushing most of those benefits and therefore your money straight down the toilet.
The Chitin Problem Nobody Talks About
Here's the uncomfortable truth that mushroom supplement companies conveniently leave off their labels: mushroom cells are encased in chitin, the same incredibly tough material that forms lobster shells and insect exoskeletons.
Your body doesn't produce chitinase, the enzyme needed to break down chitin. This means when you consume raw, dried mushroom powder, those supposedly miraculous compounds like beta-glucans, triterpenes, and polysaccharides remain locked inside cells that your digestive system simply can't crack open. They travel through your intestinal tract mostly intact, providing little more benefit than expensive fiber.
Think about it this way: if you tried to eat a lobster shell to get the meat inside, you wouldn't get very far. The same principle applies to mushroom powder.
The Marketing Sleight of Hand
Scroll through most mushroom powder websites, and you'll find plenty of talk about "organic," "whole fruiting body," and "no fillers." These aren't meaningless claims, but they're also strategic misdirection. A product can be all of those things and still be largely ineffective.
What you won't find prominently displayed:
-
Clear information about extraction methods (or lack thereof)
-
Honest discussion of bioavailability challenges
-
Actual usage instructions that would make their powder work (like "simmer this in hot water for 2 hours before consuming")
-
Standardized levels of active compounds like beta-glucans
Some companies do make quality extracted products. But they're competing in a market flooded with cheaper alternatives that look identical to the average consumer browsing online. The companies selling simple powder have little incentive to educate customers about why their product might not work as expected, as that would only hurt sales.
The Mycelium and Grain Deception
But wait, it gets worse. Many mushroom supplements are made from mycelium, the root-like structure that grows underground, cultivated on grain substrates like rice or oats.Â
Here's why this matters: when companies grow mycelium on grain, they often can't (or don't bother to) separate the mycelium from the grain it's grown on. The result? You're paying premium prices for what is essentially powdered grain with some mushroom mycelium mixed in. Tests have shown that some products contain more starch from grain filler than actual fungal compounds, along with trace minerals found within grains, like heavy metals.Â
The label might say "Lion's Mane" or "Reishi," but a significant portion of what you're getting is rice or oat powder. Quality dried mushroom supplements should be made from actual fruiting bodies or mycelium that's been separated from its growth source. This should clearly state this on the label, and ideally provide third-party testing to verify what's actually in the product, if it's not clear what you're getting is a whole mushroom. Unfortunately, in an unregulated supplement market, many companies take shortcuts that consumers end up paying the price for, purchasing expensive grain powder that does little more than add calories to their smoothie.
The Bottom Line
Functional mushrooms have legitimate health benefits, but only if those benefits can actually reach your cells. The mushroom supplement industry has built a booming business while largely ignoring (or deliberately obscuring) the fundamental bioavailability problem.
If you're going to spend money on mushroom supplements:
-
Ask questions before buying—if a company can't or won't explain their extraction process, that's a red flag
-
Be skeptical of ultra-cheap products—quality extraction costs money
-
If you're using powder, understand that you may need to prepare it properly (through extended simmering) to get any real benefit
Consumers deserve honesty about what they're buying. Until supplement companies start prioritizing transparency over profit margins, it's up to you to read between the lines and understand what's actually in that expensive dried mushroom powder you've been adding to your morning routine.
Your body can't break down lobster shells. It can't break down mushroom powder either. It's time the industry stopped pretending otherwise.
