OptiMSM, 99.9% · 2 g
One ingredient. The dose on the label is the dose in your hand, and the lot number traces it back to one supplier: Bergstrom (OptiMSM).
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
Small joint-comfort trials; graded moderate. Purity source disclosed.

- ★★★★★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.

- ★★★★★Finally, one thing per capsule
I've read too many labels that say 'proprietary blend 1,200mg'. Here it's one ingredient, one dose, printed. Bought two singles instead of my old multi.

- ★★★★★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.

- ★★★★★Gift link surprised my mum
Sent the set to my mother through the gift link and she could see exactly what was in it before accepting. She's picky — she approved.

- ★★★★★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.
