Set up Profile nowDIRTEA Tremella is a single-ingredient mushroom powder made from 100% Tremella fuciformis, a white jelly fungus long used in East Asian wellness traditions and increasingly studied for its polysaccharide content. Tremella polysaccharides are hygroscopic — they attract and bind water molecules — which is why this mushroom has earned a reputation as a skin-support ingredient taken orally. Unlike topical moisturisers, the mechanism here works from within, supporting the skin's natural moisture-retention capacity rather than sitting on the surface.
This powder suits people who want to address skin hydration through their diet and supplement routine, particularly those who have tried topical approaches and want to work at a different level. It also fits naturally into a broader functional mushroom stack, sitting alongside adaptogens or other daily powders without any complex interactions.
Practically, it dissolves reasonably well into warm drinks and is flavour-neutral enough to add to coffee, matcha, or plain water without altering the taste significantly.
DIRTEA's range is built around single-origin mushroom extracts, and this SKU keeps the formula clean: one ingredient, no fillers, no blending agents. For anyone who wants to understand exactly what they are taking and why, that simplicity is genuinely useful. If you are considering adding Tremella for skin support, pairing it with a baseline assessment of hydration, diet, and skincare routine will give you the clearest sense of what it is actually contributing.
100% Tremella Mushroom
Mix 1 teaspoon into warm water, coffee, or your drink of choice. Warm liquid tends to help the powder incorporate more evenly. Consistent daily use is generally how functional mushroom powders are approached — a single serving is unlikely to reflect the full picture.
Tremella fuciformis contains polysaccharides that are hygroscopic — they attract water molecules. When consumed regularly, these compounds are thought to support the skin's own moisture-retention mechanisms from the inside, complementing rather than replacing topical skincare.
Functional mushroom supplements are typically assessed over weeks rather than days. Most people who report noticeable changes do so after four to eight weeks of consistent daily use, though individual responses vary depending on diet, hydration, and baseline skin condition.
The product contains 100% Tremella mushroom with no listed additives, which is consistent with a vegan-suitable ingredient. That said, check the packaging for any allergen statements or cross-contamination notices relevant to your situation.
Tremella is generally considered compatible with other functional mushrooms such as Lion's Mane or Reishi. There are no well-documented interactions between common culinary or functional mushroom species when taken as food-grade powders.
Some sources draw a comparison between Tremella polysaccharides and hyaluronic acid because both are hygroscopic. The comparison is a rough analogy for the moisture-binding mechanism — it is not a claim that they are chemically identical or clinically interchangeable.

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
