Last updated: October 4, 2026 · By Martin Smith · How I research
Leptozan is a capsule sold as “ketogenic ancient minerals” for weight loss, marketed mainly to adults over 35. According to its official label, each daily serving is an 800 mg blend of three ketone salts: magnesium, calcium and sodium beta-hydroxybutyrate (BHB). This Leptozan review looks at what is in it, what published research says about BHB salts, what users report, side effects, and how buying and refunds work. I haven’t taken Leptozan myself: the review is based on the manufacturer’s website and label, published research on the ingredients, and the user reviews I found.
Correction (October 4, 2026): an earlier version of this review listed African mango, omega-3s, curcumin and fucoxanthin as ingredients, described Leptozan as a leptin supplement and gave a 180-day guarantee. The official label lists only the three BHB salts, the sales page makes no leptin claims, and the sales page gives a 90-day guarantee.

Leptozan at a glance
- What it is: a capsule containing an 800 mg blend of magnesium, calcium and sodium BHB per daily serving, sold for weight loss
- Form: capsules, 60 per bottle (a 30-day supply), ordered as 2, 3 or 6 bottles

What Is Leptozan?
Leptozan is a once-a-day capsule supplement. The sales page headline is aimed at people “over 35” who can’t lose belly fat, and the product is presented as a “Dead Sea secret”. The label calls it “ketogenic ancient minerals”, and its only active ingredients are three ketone salts: magnesium BHB, calcium BHB and sodium BHB, in an 800 mg proprietary blend per two-capsule serving. The other ingredients are gelatin (the capsule), microcrystalline cellulose and magnesium stearate, so it contains no caffeine or other stimulants.
Despite the name, the sales page doesn’t claim that Leptozan works on leptin, the hormone involved in fullness, and the label contains no ingredient sold for that purpose. The label says it is made in the United States, and it carries GMP and “FDA-registered facility” marks (FDA registration is not FDA approval). It is sold through its official website at leptozan.com.
How the Manufacturer Says Leptozan Works
According to the sales page, Leptozan uses “research-backed Dead Sea minerals” to “kickstart your fat-burning processes”. It says calcium BHB “supports fat burning”, sodium BHB “boosts energy levels to help burn more calories all day long” and magnesium BHB “helps convert food into clean energy”. The sales page also lists benefits such as faster weight loss, a faster metabolism, fewer carb cravings, all-day energy, less inflammation and better brain health.
BHB is a ketone, one of the fuels the body makes from fat during fasting or on a ketogenic diet. Drinks of ketone salts can raise blood ketone levels for a few hours: in an Oxford study, drinks providing about 12 or 24 g of BHB raised blood levels only modestly, and they returned to baseline within 3 to 4 hours. Taking ketones from a supplement is not the same as the body burning its own fat to make them, and the trials below found little extra weight loss from ketone salts. I explain what BHB salts are, what the studies found and who should be careful in my guide to BHB salts. If you’re also looking at MCT oil as a way to raise ketones, I compare it with coconut oil in my coconut oil vs MCT oil guide.
The “Dead Sea” link isn’t explained on the sales page. The label lists no Dead Sea salt or mud, and several of the sales page’s Dead Sea references are skin studies. The FAQ says you don’t need restrictive dieting, while the label says “for best results in achieving ketosis” to aim for a diet of 70% fat, 25% protein and 5% carbohydrates, which is a strict ketogenic diet. I found no published trial of Leptozan itself.

Leptozan Ingredients: What the Research Says
According to the label, each two-capsule serving contains an 800 mg proprietary blend of magnesium, calcium and sodium BHB. The label doesn’t give the amount of each salt. All three are forms of the same compound (BHB bound to a different mineral), and trials usually test mixtures of BHB salts, so each row below cites a trial of BHB salts.
| Ingredient | What the manufacturer says | What published research says | Evidence for weight loss | Study |
|---|---|---|---|---|
| Magnesium BHB | Helps convert food into clean energy and supports metabolic health | In an 8-week trial in 51 adults with excess weight on a modest calorie-cut diet, BHB mineral salts (5 g twice a day) were compared with a placebo. Weight fell in both groups, and the difference between the groups wasn’t statistically significant. The trial was funded by a ketone supplement company. | Limited | Roeth et al., 2025 |
| Sodium BHB | Boosts energy levels to help burn more calories | In a 6-week trial, adults with excess weight on a calorie-controlled ketogenic diet took either ketone salts (about 12 g of BHB twice a day) or a placebo. Weight loss was similar in both groups. | Limited | Crabtree et al., 2021 |
| Calcium BHB | Supports fat burning | In a small crossover study in 8 healthy adults, a day of ketone salts (38.7 g) added to a normal diet raised ketone levels only a little and didn’t change energy expenditure or appetite. | Limited | Hägele et al., 2023 |
| “Dead Sea minerals” (sales-page wording; not a separate label ingredient) | Ancient minerals that accelerate metabolism | I found no weight-loss trials. Research on Dead Sea minerals is mainly about skin, such as a study of bathing in Dead Sea salt for dry skin. | None found | Proksch et al., 2005 |
How I grade the evidence: Strong means consistent results in large, good-quality trials; Some means a modest effect across several trials; Limited means small, short or uncertain results; None found means I found no trials showing an effect on weight.
What the Research Means for Leptozan
The ketone-salt trials I found used about 10 to 39 g of BHB salts a day and still found little or no extra weight loss compared with a placebo. Leptozan’s daily serving is 800 mg, about a twelfth of the smallest daily dose in those trials, so it is unlikely to raise blood ketones much. Any weight loss while taking it is more likely to come from the diet changes the label suggests.
What the Manufacturer Says Leptozan Does
According to the sales page, Leptozan:
- Accelerates weight loss, especially around the belly and hips
- Increases metabolism to burn more calories
- Reduces carb cravings
- Delivers all-day energy
- Fights inflammation and protects brain health
These are the manufacturer’s claims. As the table above shows, the research on BHB salts doesn’t support them at Leptozan’s dose.
Leptozan Side Effects
Leptozan contains no caffeine or other stimulants, according to the label, so the jitters, raised heart rate and sleep problems linked to caffeine-based fat burners shouldn’t be an issue. These complaints did not come up in the customer reviews I found, but talk to your doctor before starting.
A small number of users experience mild digestive adjustment or temporary headaches during the first three to five days. If it doesn’t settle, stop and check with your doctor. Those with hypertension should note that Sodium BHB influences electrolyte balance and should consult a doctor before starting. Pregnant or breastfeeding women, anyone under 18, and those on prescription medication for blood sugar or cardiovascular conditions should seek medical guidance before use.
Is Leptozan Safe?
Ketone salts are widely sold, but they are not free of side effects at higher doses. In a small study of sodium and calcium BHB salts, three of six healthy adults had stomach or bowel symptoms after one large dose, and the researchers said regular high intake shouldn’t be taken without medical supervision. Leptozan’s dose is much smaller, which also means less sodium. The label advises anyone pregnant or nursing, under 18 or with a known medical condition to consult a physician first, and warns not to exceed the recommended dose. The strict ketogenic diet the label suggests isn’t suitable for everyone, especially people taking diabetes medication. If you are unsure, talk to your doctor before starting.
How To Use Leptozan
According to the label, take two capsules a day with an 8 oz glass of water. The label also suggests a ketogenic diet (70% fat, 25% protein, 5% carbohydrates) “for best results in achieving ketosis”, and the sales page recommends taking it daily for at least three months. Some users report fewer cravings within the first couple of weeks; any change in weight builds gradually, and results vary.
What Users Report
In the Leptozan reviews I found, a common early theme is fewer carb cravings and steadier energy, which many users say they noticed within the first two weeks, before any significant change on the scale. Some describe a smaller appetite and fewer afternoon energy dips.
Critical feedback follows a clear pattern. Users who expected fast, dramatic results within the first week report disappointment. A smaller group mentions the price of the smaller bundles as a concern, though the larger bundles cost less per bottle. In the customer reviews I found, complaints directly about the formula’s safety are uncommon.

How buying works. You order on the official website. My link opens the version of leptozan.com where ClickBank processes the payment as the retailer; the leptozan.com home page uses a different checkout, BuyGoods. The shipping policy says orders are prepared within 1 to 2 business days, and international orders can take 4 to 6 weeks or longer. The vendor doesn’t ship to some countries, including India, Ireland, Mexico, New Zealand, the Philippines and South Africa.
The 90-day money-back guarantee. According to the sales page and the refund policy, you have 90 days from your shipping date.

Leptozan is a real product with a published label and a written refund policy. To make sure you’re buying the genuine product:
- Order on the official website, leptozan.com.
- Use support@leptozan.com or 1 (866) 376-5866, the contact details on the official site and label, for questions and refunds.
- Avoid Amazon, eBay and other marketplace listings. The vendor doesn’t allow its product to be sold there, and the guarantee may not apply.

Read the sales page with care. Its headline promises a “Dead Sea secret” that works “overnight”, it shows “while supplies last” offers, and its video and claims aren’t backed by a published trial of the product.
Alternatives to Leptozan
- Berberine supplement review: one of the better-studied supplement ingredients for modest weight loss.

Final Verdict
Leptozan is a simple, stimulant-free capsule of three ketone salts. The label is clear about what is in it, but the dose is the problem: 800 mg a day is far below the 10 g or more used in ketone-salt trials, and even those trials found little or no extra weight loss compared with a placebo. The Dead Sea framing isn’t backed by the label or by weight-loss research, and the label itself points to a strict ketogenic diet for best results.
It is not the right choice for anyone expecting fast results. If you follow a low-carb diet and still want to try it, the 90-day guarantee gives you time to judge it, but note that you pay return shipping.
