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.

- ★★★★★Third order
First order was a test, second was for my husband, third is the subscription. The consistency between lots is what keeps me — same look, same certificate format, no surprises.

- ★★★★★The schedule advice is underrated
The bot told me to keep this away from my iron at a different meal. My pharmacist said the same thing when I asked. Nice to see a shop that knows timing matters.

- ★★★★★Subscribed after one month
Tried one-time first, then switched to subscribe. The cancel-anytime wording was what convinced me to commit — and it really is one click, I tested it.

- ★★★★★Better than my old brand
Switched from a supermarket brand. The form here absorbs better according to what I've read, and at least the dose isn't hidden in a blend total.
