SAC StudioTrustworthy brand, half-declared actives
Gaia Herbs earns genuine trust: lot-level Meet-Your-Herbs traceability, its own published testing claims, and a vegan liquid Phyto-Cap of organic Siberian rhodiola root extract. For a category where the actives are the entire point, though, it has a real gap — it declares rosavins (6 mg per 120 mg cap, about 5%) but never states a salidroside percentage. You can confirm half of the studied rosavins/salidroside spec, not the whole thing.
Half-declared: the label states rosavins at 6 mg per 120 mg capsule (about 5%, above the 3% SHR-5 benchmark), but it never states a salidroside percentage. That's meaningfully better than a fully undeclared extract, but still short of a product that guarantees both sides of the studied 3% rosavins / 1% salidroside ratio.
120 mg of extract per capsule, and the label directs 1 capsule twice daily — 240 mg/day, squarely inside the 200-400 mg trial window. At that dose the declared rosavins work out to 12 mg/day, matching the rosavin delivery of a 400 mg SHR-5 dose; only the salidroside side of the dose is unconfirmed.
Meet-Your-Herbs lot-level traceability is genuinely useful, and Gaia publishes its own purity and potency testing claims. No third-party seal (NSF, USP, cGMP) or outside lab name appears on the label or product gallery, so treat those claims as brand-published, not independently verified.
A vegan liquid Phyto-Cap of organic Siberian root extract — the format is well tolerated, with a clean ingredient list (vegetable glycerin, vegan capsule, water). There is no rhodiola-specific human evidence the liquid extract is better absorbed than standardized powder caps.
~$26 for 60 capsules (a 30-day bottle at the labelled 2 caps/day, about $0.87/day) is the priciest here, and you're paying a premium for a product that still leaves salidroside — half of the studied active pair — undeclared.
“Liquid Phyto-Caps absorb better than powdered extract”
There is no rhodiola-specific human evidence that Gaia's liquid extract is better absorbed than standardized powder caps; the fatigue trials used dry SHR-5 extract (Olsson 2009, PMID 19016404).
“You can verify the active rosavin/salidroside content”
The label states rosavins at 6 mg per 120 mg capsule (about 5%), so that half of the studied pair is confirmable. It never states a salidroside percentage, so the other half of the active content cannot be confirmed from the label.
An earlier version of this review said Gaia's Rhodiola Rosea Liquid Phyto-Caps state no rosavins or salidroside percentage at all, and listed the dose as ~240 mg extract blend per capsule. The Supplement Facts panel reads: Organic Siberian Rhodiola root extract 120 mg per capsule, with a sub-row of Rosavins 6 mg (about 5%); salidroside is not listed; Suggested Use is 1 capsule 2 times daily (240 mg extract, 12 mg rosavins per day). We re-read the label on Sep 3, 2026 and revised the oneLiner, lead, tldr, specs, criteria bodies, claims, findings and verdict to match, moved Standardization & Extract Match from 3 to 6.0 and Dose vs Clinical Range from 7 to 8, and moved the overall score from 5.6 (skip) to 6.8 (consider).
Gaia's Meet-Your-Herbs program tells you where the herb came from and that it's the right species — valuable, and it does go one step further than a fully undeclared extract: the label states rosavins at 6 mg per capsule. What it still doesn't tell you is the salidroside figure, the other half of the studied ratio.
At ~$26 it's the priciest cap here, and it's the only product on this list that leaves salidroside undeclared — rosavins are printed at 6 mg per cap, but that half-declaration doesn't fully offset paying the most for the least-verifiable extract.
Gaia is a quality, trustworthy herbal brand, and its panel states one of the two studied actives: rosavins at 6 mg on the 120 mg capsule (about 5%, above the 3% SHR-5 benchmark). At the label's directed dose of 1 capsule twice daily, that's 240 mg of extract and 12 mg of rosavins a day — squarely inside the 200-400 mg trial window and matching the rosavin delivery of a 400 mg SHR-5 dose. What it still doesn't give you is a salidroside figure, so half of the studied 3% rosavins / 1% salidroside spec remains unconfirmed. If you want a traceable, organic, well-tolerated liquid extract and can live with that one gap, it's a reasonable pick. If you want both halves of the studied ratio guaranteed on the label, choose a standardized 3% rosavins / 1% salidroside product instead.

Standardized 3% rosavins / 1% salidroside at the trial dose, cheaper — the salidroside figure Gaia omits, plus the full trial dose, confirmed on the label.

See it on the list →Benefit came from a defined, standardized SHR-5 extract (3% rosavins / 1% salidroside at 200-400 mg) — Gaia's panel states rosavins (6 mg on 120 mg, about 5%) but no salidroside figure. At the label's 2-capsule daily dose (240 mg extract, 12 mg rosavins) the rosavin delivery matches the top of the trial range; the salidroside side of the ratio remains unconfirmed.
Life-stress symptoms improved with a defined, standardized rhodiola extract, reinforcing that active characterization matters.
