Our ranking
-
AquaSculpt★★★☆☆
Best for: Adults on a calorie-controlled plan who want a once-daily metabolism blend with partly disclosed doses
AquaSculpt is more transparent than many rivals, disclosing zinc and chromium amounts and each botanical's standardization, and its ingredients have some research on metabolism. But eight botanicals share only 276 mg, so most are likely underdosed, and the "ice water hack" is marketing rather than science. Reasonable value in the six-bottle pack, but expect modest results at best.
-
Mitolyn★★★☆☆
Best for: Adults wanting a simple, stimulant-free antioxidant blend alongside diet and exercise
Mitolyn combines six plausible antioxidant botanicals in a once-daily capsule with a generous 90-day guarantee. However, the doses are hidden in a proprietary blend, there are no published trials of the product, and none of the ingredients has strong evidence for fat loss. It is an optional add-on at best, not the metabolic breakthrough the marketing suggests.
-
Java Burn★★★☆☆
Best for: Healthy coffee drinkers who want a convenient add-in and accept small, uncertain effects
Java Burn mixes reasonable metabolism ingredients (green coffee extract, green tea, chromium, L-carnitine and L-theanine) into a coffee powder, but the official page does not disclose doses and the research on these ingredients shows small effects at best. The marketing overstates the science, and the price is high for an unverifiable formula. The 60-day guarantee exists, but it requires returning the product and excludes shipping.
-
HepatoBurn★★★☆☆
Best for: Adults already working on diet and exercise who want a liver-focused botanical blend, with their doctor's approval
HepatoBurn includes a few ingredients with real research, such as berberine, silymarin and resveratrol, but hides every dose and makes medical claims the evidence does not support. The two-bottle minimum and refund terms that exclude shipping add to the cost and risk. It is not a substitute for medical care or lifestyle change.
The short answer
Supplements are a small part of weight management, and the research behind most weight-loss ingredients is thin. The NIH Office of Dietary Supplements puts it plainly: there is little scientific evidence that weight-loss supplements work, many are expensive, and some interact with medications. Eating patterns, activity, sleep and, when appropriate, medical treatment do the heavy lifting.
If you still want to try a supplement, the four products below are among the most advertised in the US. We ranked them on what you can actually verify: how much of the formula is disclosed, how strong the evidence is for the main ingredients, what it costs and how easy it is to get your money back.

Why AquaSculpt edges ahead
AquaSculpt is the only one of the four that discloses some amounts on its label: zinc, chromium and the total of its botanical blend. That lets you judge part of the formula instead of taking it on trust. Its ingredients, including chromium, green tea extract and berberine, have some research on metabolism, although most of the eight botanicals share just 276 mg, so individual doses are likely low. The six-bottle price is also the lowest in this group.
Mitolyn: the best guarantee
Mitolyn is built around antioxidant botanicals such as maqui berry, rhodiola and astaxanthin, and it is stimulant-free. The doses are hidden in a proprietary blend and none of its ingredients has strong human evidence for fat loss, so the mitochondria story is marketing rather than proof. Its 90-day money-back guarantee is the longest here, which lowers the cost of trying it.
Java Burn: for coffee drinkers, with caveats
Java Burn is a powder you stir into coffee. Green coffee bean extract, green tea, chromium, L-carnitine and L-theanine are reasonable choices, but research on them shows small effects at best and the official page lists no doses. It also adds caffeine from green tea to your coffee, which some people will not tolerate well.
HepatoBurn: liver framing, unclear doses
HepatoBurn ties weight to liver health and includes several ingredients with real research, such as berberine and milk thistle. It hides every dose, its marketing goes beyond the evidence, and its refund terms exclude shipping. Anyone with a liver condition should talk to a doctor rather than self-treat with a supplement.
How to choose, if you choose one
- Check what is disclosed. A label that lists amounts is easier to judge than a proprietary blend.
- Think in cost per month. Six-bottle packs look cheaper per bottle but commit more money up front.
- Read the refund terms. Note whether opened bottles qualify and whether shipping is refunded.
- Check interactions. Berberine, chromium and green tea extract can affect blood sugar and some medications.
- Buy from the official site only. Marketplace listings may be counterfeit and are usually outside the guarantee.
Who should skip all four
Talk to your doctor before taking any of these if you are pregnant or breastfeeding, take diabetes, blood pressure or blood-thinning medication, have liver or kidney disease, or are under 18. If weight gain is sudden or unexplained, see a doctor before trying a supplement.

How we ranked these
Each product was scored with our standard method: strength of evidence for the main ingredients (weighted most), label transparency, value for money and refund terms. We analyzed the official labels and sales pages and the published research on each ingredient. We did not test the products on people, and commissions do not affect the order.
