✓ Also buy if…- You can confirm a sulfate-form SKU for a small evidence edge over HCl
- You want a large bottle that covers most or all of a trial cheaply
✗ Also skip if…- You want the absolute cheapest full-dose combo — Kirkland (#4) is less
NOW Foods is the dependable middle option: the full trial dose, a fair price, and a brand whose in-house testing labs genuinely outperform most value competitors. On the SKUs that use glucosamine sulfate, you get a small form-quality edge for not much money. It lands at #9 rather than higher only because it lacks a headline third-party certification and the form varies by product — so you have to check the panel.
For a straightforward, well-tested combo trial that won't dent your wallet, NOW is a safe call. Here's the full breakdown — including how to confirm you're getting the sulfate version.
