Weight Management

A complete vegan meal powder with 40 g protein, 11 g fiber and 27 vitamins and minerals per 400-calorie serving; fully disclosed, but the taste is divisive.

Juice-style clear whey: 20 g protein in an 80-calorie, sugar-free scoop with Informed Choice certification, though foaming and flavor split reviews.

A true zero-carb whey isolate: 25 g of protein plus a broad vitamin and mineral blend in a 110-calorie scoop, at a price above most rivals.

A tasty plant-based shake with 25 g protein, 6 g fiber and 26 vitamins and minerals, but at about $4.66 a serving its long superfood list is mostly undosed.

NSF Contents Certified berberine in HCl and phytosome forms. Well made, but the average weight change in trials is about 2 lb and it interacts with many drugs.

A cheap, single-ingredient konjac fiber (1,725 mg per serving) taken before meals for fullness. Honest and GMP-made, but the average weight effect in trials is small.

Three branded extracts (lemon, saffron, red orange) at their studied doses and cleanly tested. But the trials are small, it's no GLP-1 drug, and it costs $80 a month.

The viral ACV gummy tastes good and is easy to take, but it doesn't disclose acetic acid, weight-loss evidence is weak, and six a day adds 12 g of sugar.

A novel Akkermansia, C. butyricum and B. infantis probiotic sold on the GLP-1 buzz. It contains no GLP-1, has no human appetite trial and costs $64–89 a month.

A high-caffeine fat burner (265 mg per serving, up to 530 mg a day) with yohimbe and green coffee. Weak weight-loss evidence and a history of liver-injury cases.
