Buy it. The dose-and-ratio match that most rhodiola supplements miss. 250 mg of a 3% rosavins / 1% salidroside extract per cap puts a single pill inside the studied 200-400 mg range and holds the SHR-5-style ratio.
~$13~$0.22 per 250 mg capsule
Why It Scores 8.4 — And The Label Line Behind Each Number
Standardization & Extract Match
30% of scoreLabeled 3% rosavins and not-less-than 1% salidroside — the ~3:1 profile of the SHR-5 extract used in the classic night-duty and stress-fatigue trials. This is the axis that matters most for rhodiola, and Life Extension nails it.
- Standardization
- 3% rosavins / NLT 1% salidroside
Dose vs Clinical Range
25% of score250 mg per capsule sits mid-window of the 200-400 mg range used in trials — the best dose fit here. You can take one for the low end or two for the high end without splitting anything.
- Dose
- 250 mg extract/cap (label: 2/day)
Third-Party Testing
20% of scoreProduced in an NSF GMP-registered facility, non-GMO and gluten-free, with Life Extension's certificate-of-analysis program. No banned-substance certification (Thorne Rhodiola is NSF contents-certified under NSF/ANSI 173, not NSF Certified for Sport), but well above the value-brand baseline.
- Testing
- NSF GMP-registered facility, non-GMO
Form & Bioavailability
10% of scoreA standard veg capsule of root extract. You can take one for the low end or two for the high end without splitting anything, and a moderate 250 mg cap makes it easy to start low.
- Form
- Veg capsule (root extract)
Value per Clinical Dose
15% of score~$13 for a correct-dose, correctly-standardized cap is excellent. The asterisk is the two-a-day label turning 60 count into 30 days, so true cost-per-day is roughly double the sticker math.
- Count
- 60 veg capsules (~30-day supply)
- Cost per dose
- ~$0.22/cap (~$0.44/day at 2/day)

Marketing Claims Vs. Reality
250 mg per capsule matches the dose used in rhodiola fatigue trials
Landmark trials dosed roughly 170-576 mg/day of SHR-5; 250 mg (or 2×250) lands inside that 200-400 mg effective window (Olsson 2009, PMID 19016404; Darbinyan 2000, PMID 11081987).
Rhodiola is a proven energy stimulant
It is an adaptogen, not a stimulant — benefits show up as reduced stress-related fatigue and better mental performance under load, not acute energy. Systematic reviews call the evidence modest and the trials small (Ishaque 2012, PMID 22643043).
What Our Test Actually Found
The ratio is the whole point
The extract used in the best-known trials (SHR-5) is standardized to about 3% rosavins and 1% salidroside. Life Extension states exactly this, which is why it beats several 500 mg caps that carry more milligrams but an inverted or salidroside-only profile.
Read the serving size before you judge the price
At ~$13 the bottle looks like a steal, but the directed 2/day means 30 days, not 60. It is still the best value-per-correct-dose on the list, just not half the price of the 500 mg single-cap options once you account for servings.
Full analysis: all pros & cons (6), buy if / skip if
- Only cap here whose single-pill dose sits mid-window of the 200-400 mg trial range
- Correct 3% rosavins / 1% salidroside SHR-5-style ratio, clearly labeled
- NSF GMP-registered facility with a published COA program
- Cheap per correct dose and single-ingredient (no filler blends)
- Label directs 2/day, so 60 count is really a 30-day supply
- No banned-substance certification — tested athletes should check nsfsport.com for the exact rhodiola, since Thorne Rhodiola is not NSF Certified for Sport either
- Only cap here whose single-pill dose sits mid-window of the 200-400 mg trial range

250 mg of a 3% rosavins / 1% salidroside extract per cap puts a single pill inside the studied 200-400 mg range and holds the SHR-5-style ratio. NSF GMP facility, ~$13, single ingredient. The only real catch: the label directs two per day, so the 60-count bottle is a 30-day supply, not 60.
Rhodiola's fatigue evidence rests on a specific extract, at a specific dose, standardized to a specific ratio. Life Extension is the pick that respects all three: 250 mg per capsule of a 3% rosavins / not-less-than 1% salidroside extract, made in an NSF GMP-registered facility. It is not a stimulant and it will not fix burnout, but for stress-related fatigue it is the closest off-the-shelf match to what was studied — and it is cheap.
The default rhodiola pick for anyone chasing the studied effect
If you want the extract, dose, and ratio the fatigue research actually used — without overshooting or guessing at actives — this is it. Buy it, dose 250-500 mg in the morning, and judge it over 2-4 weeks for stress-related fatigue, not as a pre-workout jolt.
If This Doesn’t Fit — Try These
02Thorne Rhodiola
If independent testing matters most — you want verified label contents and contaminant screening — Thorne is the pick.
03NOW Rhodiola 500 mg
NOW is the reliable default: a real, testable brand with the correct standardization at a fair price.
Quick Answers
How many capsules should I take?
One 250 mg cap covers the low end of the studied range; the label's 2/day (500 mg) reaches the high end. Take it in the morning — rhodiola late in the day can disturb sleep for some people.
Will I feel it right away?
Probably not. This is an adaptogen, not a stimulant. Trials measured reduced stress-related fatigue over days to weeks, so give it 2-4 weeks before deciding.
