Inside this capsule
This capsule
Rhodiola Rosea
3% rosavins, 1% salidroside · 400 mg
One ingredient. The dose on the label is the dose in your hand, and the lot number traces it back to one supplier: Nektium (Rhodiolife).
A typical blend capsule

“Proprietary blend, 1,200 mg” — many names, one number, no way to know how much of anything you took, or what competes with what inside.
On the evidence
Human trials are mixed but promising; we grade it moderate rather than overclaim.
Where it sits on our scale
Traditional use
Long use, thin trials — we say so
● Moderate evidence
Human trials, small or mixed
Strong evidence
Repeated randomised human trials
Every ingredient in the catalogue carries one of these three grades — including the ones we grade down. A scale you never see the bottom of is not a scale.

- ★★★★★Good, shipping takes patience
Product quality feels premium and I like the per-day pricing. Jakarta delivery was on the slower end of the estimate, about 10 days. Would still reorder.

- ★★★★★Paper trail is the point
I photograph the lot number of everything I take. This is the only store where that number leads to an actual document. Repeat customer now.

- ★★★★★Works out cheaper per day
The per-day price framing is honest — easier to compare than bottle prices. Delivery through the importer took 12 days to Bangalore, within what they quoted.

- ★★★★★Respects my requirements
As a Muslim buyer I usually have to email brands about capsule sources. Here the shell material is printed on the page and filtered automatically. Thank you.
