Our verdicts

Glucomannan 575 mg Veg Capsules

NOW Glucomannan is cheap, cleanly formulated and honestly labeled, which puts it ahead of most weight-loss products. Keep expectations modest, though: trials show a small average weight difference at best. Treat it as an appetite aid alongside diet changes, and always take it with a full glass of water.

GLP-1 Probiotic

Pendulum GLP-1 Probiotic is a carefully made, novel probiotic sold on a mechanism rather than on results. No human trial shows it reduces appetite or body weight, and 'GLP-1' on the label is not equivalent to GLP-1 medication. At roughly $2–3 a day, it makes sense only as an experiment for someone curious about Akkermansia, not as a weight-management tool.
