Tremella Dosage & Consumption

What this page covers: the exact Tremella doses used in the cognition and metabolic RCTs, and how they compare to a typical retail capsule. It does not evaluate specific supplement products or make treatment claims. See the Tremella hub for the full research context.
In one line

The cognition trial used 600-1200 mg/day, roughly in range of a typical retail capsule serving. The metabolic trial used a beverage with a stated beta-glucan content, a different format most capsule labels don't state a directly comparable figure for.

Why the formats differ

The cognition trial used a straightforward daily milligram dose, which lines up reasonably well with a typical capsule serving. The metabolic trial used a beverage standardized to a specific beta-glucan weight (6.4 g), a more concentrated and differently measured format; a capsule labeled only by total extract weight, without a beta-glucan percentage, can't be reliably compared to that trial's dose. See the Tremella hub for what named brands disclose about their beta-glucan percentage.

Safety at the doses studied

Per Ban et al., 2018, adverse event rates were similar between the Tremella groups (40.4% and 35.1% for the two doses) and placebo (41.4%) over the 8-week trial period. This page doesn't evaluate longer-term use beyond the 8- and 12-week trial durations covered here, or individual medication interactions; anyone with a mushroom allergy, anyone pregnant or breastfeeding, and anyone on blood-sugar medication should talk to a doctor before starting Tremella at any dose.

Frequently Asked Questions

What dose of Tremella was used in the cognition trial?

600 mg or 1200 mg per day, taken for 8 weeks, per Ban et al., 2018. Both doses showed improvement over placebo on a subjective memory questionnaire; the abstract available for this page doesn't specify whether the higher dose outperformed the lower one.

What dose of Tremella was used in the metabolic trial?

A 180 mL beverage containing 6.4 g of beta-glucan, once daily, for 12 weeks, per Gitsomboon et al., 2024. This is a beverage format with a stated beta-glucan content, not a plain milligram-of-mushroom-powder dose, so it isn't directly comparable to a capsule label.

Does a typical Tremella capsule match either trial dose?

Roughly, for the cognition trial. A common retail serving of 500-1,000 mg/day sits within or near the 600-1200 mg/day range used by Ban et al., 2018, though that trial used a specific extract, not necessarily the same one as any given retail product. The metabolic trial used a beta-glucan-content beverage format that most capsule labels don't state a directly comparable number for.

Is it safe to take Tremella long-term?

The two trials on this page ran 8 and 12 weeks, not longer. Ban et al., 2018 reported adverse event rates comparable to placebo over its 8-week duration. This page doesn't evaluate longer-term use or individual medication interactions; anyone with a mushroom allergy, anyone pregnant or breastfeeding, and anyone on blood-sugar medication should talk to a doctor before starting Tremella at any dose, given its studied metabolic effect.
