Glucomannan is a soluble fiber from the konjac root that absorbs many times its weight in water and forms a viscous gel in the stomach. Taken before meals with water, it expands and promotes a sense of fullness, which can reduce how much you eat. Chromium is added for blood-sugar support and B-vitamins for normal energy metabolism. The trace green coffee provides negligible stimulation, keeping the experience gentle.

Lipozene's sole active ingredient is glucomannan, a soluble konjac fiber. Taken before meals with water, it absorbs fluid and swells into a gel that fills part of the stomach, which can promote fullness and modestly reduce food intake. There is no caffeine, thermogenic, or metabolic-stimulant component, so any effect comes purely from the fiber's bulking and satiety action within a reduced-calorie diet.

Glucomannan at around 3 g/day is the dose tied to an EFSA-recognized claim for weight reduction in a calorie-restricted diet, and several randomized trials and reviews show small, real reductions in body weight when used as a pre-meal preload. However, systematic reviews (e.g. Zalewski et al., 2015) found the effect inconsistent and modest, and NIH notes limited long-term, high-quality data. The non-fiber ingredients contribute little independent weight-loss evidence.

Glucomannan has clinical support for small weight reductions when used as a pre-meal preload in a calorie-restricted diet, with an EFSA-recognized claim at roughly 3 g/day; however, reviews describe the effect as modest and inconsistent, and NIH notes limited long-term data. Critically, Lipozene's specific advertising claims were challenged and resolved through an FTC settlement, so the brand's marketed efficacy should be discounted relative to the underlying ingredient's modest, evidence-based effect.

Because the active ingredient is bulking fiber, the most common effects are bloating, gas, and looser stools, which often ease over time. The most important safety point: always take glucomannan with a full glass of water and never dry, as it can swell in the throat or esophagus and pose a choking or blockage risk. This is educational information, not medical advice.

As a bulking fiber, Lipozene most commonly causes bloating, gas, and looser stools, which often ease with continued use. The key safety rule for any glucomannan product: take each dose with a full glass of water and never dry, because the fiber can expand in the throat or esophagus and create a choking or obstruction hazard.

As of May 2026, a one-month supply is about $59.99 on the official site, with multi-month bundles lowering the monthly cost. There is no insurance coverage. A 90-day money-back guarantee is advertised. Note that generic glucomannan supplements deliver the same key fiber for a fraction of the price.

As of May 2026, Lipozene generally runs about $15-$30 depending on bottle size and retailer, with frequent buy-one-get-one offers; the 120-capsule Mega Bottle sits at the higher end. The low headline price can be offset by multi-capsule dosing and aggressive upsells. There is no insurance coverage, and generic glucomannan is a cheaper way to get the same fiber.

Marketed to adult women seeking appetite support, though the mechanism applies to anyone. Not for those under 18 or who are pregnant or breastfeeding without clinician approval. People with swallowing difficulties, esophageal narrowing, or who take oral medications (timing matters, as fiber can affect absorption) should consult a clinician first.
