Registry check · Rhodiola Rosea
Does anyone independently verify Rhodiola Rosea supplements?
1 of the 11 Rhodiola Rosea products on this page is confirmed in NSF/ANSI 173: Thorne Rhodiola 100 mg. Thorne Rhodiola 100 mg does not show the mark on the listing, so the table’s certification column, which repeats the listing, does not show it either. For the others, the listing may name a certification, but we did not find it in a public registry — that is not evidence against them, only an absence of independent confirmation.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the Rhodiola Rosea dose column either way.
The 11 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.

These Rhodiola Rosea servings are not comparable to each other
Pure Encapsulations Rhodiola Rosea 100 mg states 100 mg a serving and Bronson Rhodiola Rosea 1000 mg states 1,000 mg, both occupy one row of the same price column. Double Wood Rhodiola Rosea 500 mg is the lowest here at $0.16 a day, and its serving (500 mg) is not smaller than most, so its low price is not down to a small serving. Before comparing Double Wood Rhodiola Rosea 500 mg with Nootropics Depot Rhodiola Rosea 500 mg (3% Rosavins), check what each calls a serving.
