Strip away the marketing and Lipozene's Supplement Facts panel lists one active: a 1,500 mg proprietary blend of Amorphophallus konjac, the plant glucomannan comes from, per two capsules. The directions are, to its credit, the closest on this list to the trial schedule: two capsules 30 minutes before meals, up to three times per day, with at least 8 oz. of water, and the full choking warning is printed. Then the rest: gelatin, titanium dioxide, magnesium silicate and artificial color FD&C Blue #1, no testing statement, and a front label that says clinically proven to reduce weight and body fat.
1,500 mg before meals up to three times per day is the closest schedule to the trials; the panel declares a proprietary blend of Amorphophallus konjac rather than a glucomannan amount.
Two capsules 30 minutes before meals with at least 8 oz. of water and a full choking and swallowing warning are printed.
No third-party, GMP or laboratory statement on the label or in the listing gallery.
Gelatin capsule with titanium dioxide, magnesium silicate, stearic acid, cellulose and artificial color FD&C Blue #1.
About $0.55 per 1,500 mg serving, more than twice the cost per gram of NOW's capsule.
“Clinically proven: helps reduce weight.”
The label cites no study. Independent evidence is mixed at best: a 2014 meta-analysis of eight randomized trials found no statistically significant weight loss from glucomannan (Onakpoya), and a 2013 trial found none versus placebo (Keithley).
“78% of each pound lost was pure body fat.”
The listing attributes this to two company studies and gives no citation; the 2013 independent trial found no change in body composition.
“1500 mg per serving.”
The panel declares a 1,500 mg proprietary blend of Amorphophallus konjac per two capsules.
The only active on the panel is konjac root. That is the same fiber as every other product on this list, in a blue capsule, at more than double the price per gram of NOW's.
Two capsules before each meal with a full glass of water is how the trials dosed, and the warning is all there. The capsule itself adds titanium dioxide and an artificial dye that none of the plain fiber brands use.
Lipozene is not a scam ingredient; it is ordinary glucomannan with good directions. It is an expensive way to buy it, in a capsule with additives the others avoid, behind a claim the independent evidence does not support. Buy NOW and follow Lipozene's schedule.

1.725 g of glucomannan per three vegetarian capsules, taken once or twice a day before a meal, with the water rule, the timing and the choking caution all printed on the bottle.
See it on the list →Nothing but glucomannan: 2 g per half teaspoon, about 114 servings a jar, at half the cost per gram of any capsule here. It has to be measured, stirred and drunk before it gels.
See it on the list →1.995 g of glucomannan per three vegan capsules with only magnesium stearate added, Non-GMO Project Verified, and the fullest choking warning on the list; the smallest bottle and the highest price per gram among the plain capsules.
See it on the list →A meta-analysis of eight randomized trials found a non-significant difference in weight loss between glucomannan and placebo (mean difference -0.22 kg); adverse events included abdominal discomfort, diarrhea and constipation.
In 53 overweight and moderately obese adults, 1.33 g of glucomannan with 8 oz of water one hour before each meal for eight weeks was well tolerated but produced no more weight loss than placebo and did not change body composition, hunger or fullness.
