Removing a fat burner from the market does not prevent its neighbor from continuing to circulate on the internet, sometimes under the radar. Some of these products slip through the cracks, accessible with a simple click, while medical reports accumulate. The effectiveness of the moka burner varies from one formula to another, but the warnings are becoming increasingly urgent for those whose health is already fragile.
Vigilance is essential: doctors from the Addictovigilance network have observed cases of hypertension and palpitations occurring after taking supplements containing moka or concentrated caffeine. Health authorities are urging caution, especially among individuals with a fragile cardiovascular background or a history of metabolic disorders.

What we really know about fat burners for weight loss
The moka burner, part of the NutriSolution range, joins the long list of dietary supplements targeting weight loss. Its recipe revolves around ingredients deemed natural: green coffee (and its chlorogenic acid), green tea, guarana, chromium, L-carnitine, vitamin B6, piperine extracted from black pepper, and sometimes garcinia cambogia. All these active ingredients do not act in the same way: some aim to activate thermogenesis and fat burning, while others seek to curb appetite or give a boost to metabolism.
Scientific results paint a nuanced picture. Green coffee and its chlorogenic acid have shown modest effects on weight loss in a few trials. However, the data remains scattered, with no solid consensus. Caffeine, which is abundant in green tea and guarana, does indeed stimulate metabolism, but the line between an active dose and a risky dose is thin. Health professionals remind us that the only reliable way to lose weight sustainably is through reducing caloric intake and regular physical exercise. The moka burner cannot replace a balanced diet or a healthy lifestyle.

Before any use, experts recommend seeking a medical opinion on the moka burner, especially if one has a history of heart problems, metabolic disorders, or is currently on medication. Pregnant or breastfeeding women and adolescents are also included in this warning. Among the reported side effects: nervousness, digestive issues, insomnia. These reactions should not be minimized.
Does the moka burner pose health risks? The opinion of medical experts
Designed by NutriSolution, the moka burner raises questions among health professionals. Organizations such as ANSES, EFSA, and WHO remind us that consuming these supplements exposes individuals to several side effects. The most common affect the nervous system and heart: insomnia, palpitations, nervousness, anxiety, headaches. These symptoms primarily concern those sensitive to caffeine, a central component of the moka burner via green coffee, green tea, and guarana.
Other complications add to the list. Digestive disorders, nausea, diarrhea, abdominal pain, regularly occur, especially due to chlorogenic acid and garcinia cambogia, which is sometimes included in the formula. Garcinia cambogia, already suspended as a precaution in France in certain supplements, has been associated with serious liver or heart damage. In terms of interactions, the moka burner is not harmless: it can amplify the effects of antihypertensives, MAOI-type antidepressants, or anticoagulants, exposing individuals to unexpected reactions.
The use of this product is not suitable for individuals with heart conditions, hypertension, nor for pregnant or breastfeeding women and adolescents. A medical opinion remains essential if treatment is ongoing or in the case of chronic illness. In many cases, self-medication turns into an unnecessary risk.

Benefits, limits, and precautions: what to remember before using the moka burner
NutriSolution highlights the moka burner’s ability to accelerate weight loss through the activation of metabolism and thermogenesis. Green coffee, guarana, green tea, chromium, L-carnitine, vitamin B6, black pepper… the combination of these natural ingredients aims for increased fat burning and reduced appetite. User reviews sometimes mention a boost in energy during workouts, which can help maintain motivation.
However, specialists insist that no supplement can replace a balanced lifestyle. The moka burner is only a temporary aid, not a standalone solution. Serious studies agree that effectiveness depends on a holistic approach: a suitable diet, regular physical activity, and a coherent lifestyle.
A limited duration of use (eight to twelve weeks, followed by a break) is recommended to minimize risks. Before starting, it is preferable to discuss it with a healthcare professional, especially in cases of chronic illness or medication use.
Here are the main precautions to know before any use:
- Do not use the moka burner during pregnancy, breastfeeding, in adolescents, or in individuals with heart conditions.
- Be wary of possible interactions with antihypertensive, antidepressant, or anticoagulant medications.
Relying on the promise of a dietary supplement will never replace the fundamentals that have proven effective: a balanced plate, movement, and a rhythm suited to one’s needs. At a time when the temptation of a miracle solution looms, vigilance remains the best ally.
