Endoca shiitake supplements come in two formats, both made from organic shiitake extract rather than milled mushroom powder. The extract capsules hold 350mg each, 10,500mg across the bottle. The gummies carry the same species in a sugar-free, plant-based chew. Every batch is independently tested before release.

Both shiitake formats, compared by what each holds, who it suits and what the label states.
| PRODUCT | FORMAT | PER SERVING | BEST FOR | KEY COMPOUNDS |
|---|---|---|---|---|
| Shiitake Mushroom Extract | Capsule | 350mg extract (10,500mg per bottle) | The most extract per serving | Triterpenoids, nucleotides, phenolic compounds |
| Shiitake Mushroom Gummies | Gummy | Stated on the label | A daily chew with no added sugar | Organic shiitake extract, plant-based formula |
Shiitake is Lentinula edodes, a mushroom that grows on hardwood logs and has been a mainstay of East Asian cooking for centuries. A shiitake supplement turns that familiar food into a measured daily format, using extract rather than the whole dried mushroom. The difference from cooking with it is measurement. A handful of shiitake in a pan has no stated weight of anything. A capsule of our shiitake extract holds 350mg, the same every time, and the label says so.
The common formats are shiitake mushroom capsules and gummies. A capsule holds dried extract with nothing added. A gummy carries the extract in a chewable, plant-based base without added sugar. Our capsules hold 350mg of extract each and 10,500mg across the bottle. The gummy states its extract per serving on the label, and it shares its formula with the other species in our mushroom gummy range, so moving between species does not change the base you are chewing.
Shiitake is one of the most widely studied culinary mushrooms, so there is plenty of published research to read. That research is still developing, and we make no health claim for it here. It is not psychoactive and is not related to psilocybin mushrooms. Shiitake extract contains triterpenoids, nucleotides and phenolic compounds alongside its polysaccharides. Those names are listed so you know what the extract is made of, not to suggest what any of them does.
People who choose shiitake usually know the mushroom from the kitchen and want it in a daily format.
We describe formats here, not outcomes, because the research on shiitake is still developing and we would rather keep to what the label states.
A measured daily format of shiitake mushroom, Lentinula edodes. Endoca sells shiitake as extract capsules and as gummies, both made from organic shiitake extract rather than milled mushroom powder, and each label states what a serving holds.
Shiitake mushroom capsules hold 350mg of extract each and have no taste. Gummies are easier to keep taking every day. Pick the capsule for the highest stated weight, or the gummy if a chew is the format you will actually stick with.
Check whether it says extract or powder, whether mycelium or a grain is listed, and whether it gives both a per capsule weight and a bottle total. Ours says extract, 350mg a capsule and 10,500mg a bottle.
Powder is the dried, ground mushroom or mycelium. Shiitake extract has been hot water extracted to open the cell walls and concentrate the compounds inside. That makes the extract weight a more useful figure than the same weight of powder.
Shiitake contains triterpenoids, nucleotides and phenolic compounds alongside its polysaccharides. We list them so you know what the extract is made of. We do not attach any statement about what those compounds do in the body.
Yes. Both formats are made from certified organic shiitake extract, the ingredient the label weight refers to. The gummies use our plant-based mushroom gummy formula with no added sugar. Every batch is independently tested before release, and our lab testing page explains how.
No. It is a culinary mushroom and is not related to psilocybin species. It has been cooked in East Asian kitchens for centuries, and extracting it with hot water does not change what kind of mushroom it is.
No. Cooked shiitake is a food with no stated content. A shiitake supplement uses hot water extract, concentrated and dried, so a capsule holds a fixed 350mg. Eating the mushroom and taking the extract are simply different things.
This page holds shiitake only, as capsules and gummies. The mushroom extract capsules page carries six other species, and the gummies range has eight. Our lion’s mane supplements page sets out the same two formats for lion’s mane, so the labels read the same way.
Shiitake is the mushroom most people have already eaten, which makes it easy to sell as a supplement without saying much about what is in the bottle. Many shiitake supplements are dried, ground mushroom or mycelium grown on grain. Ours are made from extract, so the figure on the label is the extract itself. Read the ingredient line before the front of the pack. If it says powder or mycelium, the weight is the whole dried material, substrate included where there is one. If it says extract, as ours does, the weight is what is left after the mushroom has been extracted and concentrated.
The shiitake extract is made by hot water extraction, which opens the chitin cell walls that human digestion cannot break down, then concentrates and dries what comes out. Each capsule holds 350mg of that extract, and the bottle holds 10,500mg in total. Those two figures answer different questions. The per capsule weight is what you take each time. The bottle total tells you how much extract you are buying, which is the number to use when you compare one brand’s bottle against another’s. A label that gives only one of them leaves out half the picture.
The two formats suit two habits. A capsule is the most extract per serving and has no taste. A gummy is easier to keep taking every day. Both are organic, and every batch is independently tested. The gummies are made to the same plant-based, sugar-free formula as the rest of our mushroom gummy range, and the extract per serving is stated on the label. If the highest figure per serving is what you are after, the capsule is the one to pick. If you know a capsule would sit forgotten in a cupboard, the gummy is the more honest choice.

Shiitake gummies carry the species in a sugar-free, plant-based chew. They use the same formula as the rest of our mushroom gummy range, and the extract per serving is printed on the label.
Shiitake capsules hold 350mg of extract each, with no taste and no sweetener. The bottle holds 10,500mg in total, which makes the capsule the format with the highest stated weight.

Each jar and bottle holds shiitake only, not a blend, so you know exactly what you are taking and can compare it directly with any other single species product.
Our mushroom extract capsules page holds lion’s mane, chaga, maitake, cordyceps, turkey tail and reishi, all in the same capsule format, if you want to add a second species later.
More Species as Gummies
The mushroom gummies range has eight species, from lion’s mane to tremella, with oyster, golden oyster, poria cocos, phellinus and chaga sitting alongside shiitake.
If you are new to functional mushrooms, a familiar species like shiitake is a simple place to begin, and the full functional mushrooms range is the next place to look.
