A bigger ratio looks like a better product and often is not. The number describes an input, and the thing you care about is the output.
A 10:1 ratio means ten units of starting material were used to produce one unit of finished extract. It describes the input, not the result, so it says nothing by itself about how much of any specific compound ended up in the jar.1 A ratio is only informative when the label also states what the starting material was and reports a beta-glucan figure. Without those two, a higher number is a bigger claim rather than a better product.
Read literally, an extract ratio is a statement about a factory, not about a jar.
When a label says 10:1, it is reporting that ten kilograms of starting material were processed to yield one kilogram of finished extract. The intention is to communicate concentration, and in a well-run process it does. The problem is that the figure is entirely dependent on a variable the ratio itself does not mention: what the ten kilograms were.
Ten kilograms of dried fruiting body is a different starting point from ten kilograms of mycelium harvested along with the grain it grew on, and in commercial production the latter is common.1 Both can honestly print 10:1. They are not the same product.
Three reasons a higher ratio can mean less than it appears.
This is why two products both printing 10:1 can sit at very different prices and both be priced correctly.
Ask for a beta-glucan percentage. Beta-glucans are the polysaccharides specifically associated with mushrooms, and a stated percentage is a claim about the finished product rather than about the process that made it. It is also testable, which is the important part.
Watch for the substitution: "total polysaccharides" is a much broader category that also captures starch, and starch is what a grain substrate contributes. A grain-grown product can therefore post a high total polysaccharide figure that has little to do with the mushroom. A label that reports beta-glucans has chosen the number that is harder to flatter.
It is worth keeping the whole discussion in proportion. The human research on Lion's Mane is limited, and the most cited recent study is a small pilot trial covering cognitive measures, stress and mood over a short period, which did not establish an optimal extract strength or compare ratios.4 No trial has told us that 10:1 outperforms 8:1 in people, because none has asked. What the research does support is weeks of consistent daily use, which is an argument for buying something you can afford to keep buying rather than the most concentrated product on the shelf.
Talk to a clinician who knows your history before starting a new supplement, especially alongside prescription medication. Persistent difficulty with focus or memory is a reason to have it looked at rather than to keep comparing extract strengths.5

Ten units of starting material were processed to produce one unit of finished extract. It is a statement about the input, so it tells you nothing on its own about how much of any particular compound is in the jar.
Not necessarily, and no human trial has compared them. The ratio does not say which compounds survived or what the starting material was, so a higher number applied to grain-heavy input is a concentrated version of grain-heavy input.
A stated beta-glucan percentage, because that is a claim about the finished product and it can be tested. Then the milligrams of extract per serving, so you can compare two products on what you actually receive.
Because total polysaccharides is a broader category that also captures starch, and starch is what a grain substrate contributes. It is the number that flatters a grain-grown product, which is why a beta-glucan figure is more informative.
Only if the label also states the starting material and reports a beta-glucan percentage. Without those, a large ratio is a large claim about a process nobody outside the company has inspected.
