💪 Force Addict Pro Expert Tip
A fat burner does not create a calorie deficit for you. Lipoxyl can support your energy, increase thermogenesis and improve fat mobilization — but without a genuine calorie deficit and structured training, its effect will remain limited. Nutrition always remains the primary lever during a cutting phase.
What is Lipoxyl 100X Elite?
Lipoxyl 100X Elite is a dietary supplement from the First Iron Systems range, available as an effervescent powder. This format is appreciated for its convenience and rapid absorption. Unlike capsule-based burners, the effervescent form allows the active ingredients to dissolve quickly and may be more comfortable for digestion for some users.

The active ingredients in Lipoxyl 100X Elite
The effectiveness of a fat burner relies entirely on the quality and dosages of its ingredients. Here are the main active ingredients found in the Lipoxyl formula and their documented effects.
Caffeine
Caffeine is the most studied and effective thermogenic active ingredient. It increases resting energy expenditure, stimulates lipolysis, and improves training performance.
Green tea extract (EGCG)
Green tea extract, rich in epigallocatechin gallate (EGCG), works synergistically with caffeine to increase thermogenesis. Dulloo et al. (1999, American Journal of Clinical Nutrition) showed in 10 healthy men that a green tea extract (50 mg of caffeine + 90 mg of EGCG) significantly increased 24-hour energy expenditure (+4 %, p<0.01) and reduced the respiratory quotient (from 0.88 to 0.85, indicating increased fat oxidation), with urinary norepinephrine excretion 40 % higher than placebo. Key finding: caffeine alone at an equivalent dose (50 mg) had no effect on energy expenditure in the same study. Therefore, it is the specific caffeine + catechin synergy that produces the thermogenic effect, not caffeine in isolation.
L-Carnitine
L-Carnitine acts as a transporter of fatty acids to the mitochondria, where they are used to produce energy. Pooyandjoo et al. (2016, Obesity Reviews) published a systematic review and meta-analysis of 9 randomized controlled trials (911 participants), showing that carnitine supplementation resulted in significantly greater weight loss than the control group (-1.33 kg on average) and a reduction in BMI. However, the authors noted that the magnitude of this weight loss decreases significantly over the duration of supplementation (p=0.002) — the effect is therefore more pronounced at the beginning of the course.

B vitamins
B vitamins contribute to energy metabolism and reducing fatigue — particularly useful during a cutting phase when calorie intake is reduced.
What to know about effervescent burners
Lipoxyl's effervescent format offers a genuine advantage: the active ingredients are absorbed more quickly than in capsules, hydration is included, and the product is generally better tolerated by the stomach. Its caffeine + green tea synergy is specifically documented as more effective than caffeine alone for thermogenesis.
Who is Lipoxyl 100X Elite for?
Users in an active cutting phase
For athletes who train regularly and aim to support fat loss while maintaining satisfactory energy levels despite calorie restriction.
People sensitive to capsules
Lipoxyl's effervescent format, diluted in water, is often better tolerated by the digestive system than traditional capsules.
Users looking to combine energy and thermogenesis
Thanks to its caffeine and B vitamins, Lipoxyl can also be used as a pre-workout energy supplement during cutting workouts.
How to use Lipoxyl during a cutting phase?
- take in the morning or before training;
- dilute in 250 to 300 ml of cold water;
- follow the manufacturer's recommended doses;
- do not combine with other sources of caffeine;
- use as part of a structured calorie deficit;
- take regular breaks to maintain sensitivity to stimulants.
⚠️ Force Addict Pro Expert Tip
Do not use Lipoxyl after 4 p.m. if you are sensitive to caffeine. Quality sleep is one of the most important factors for fat loss and muscle preservation during a cutting phase.
Lipoxyl vs. other burners: CLA and L-Carnitine
Lipoxyl differs from non-stimulant burners such as CLA or L-Carnitine through its thermogenic and energizing component. While CLA mainly works by progressively promoting the use of fat as energy, and L-Carnitine optimizes the transport of fatty acids to the mitochondria (with a more pronounced effect at the beginning of a course according to Pooyandjoo et al.), Lipoxyl provides direct metabolic stimulation through caffeine and EGCG. These approaches are complementary. To learn more, see our comparison CLA or L-Carnitine: which fat burner should you choose?

Lipoxyl 100X Elite est-il un brûleur de graisse thermogénique validé scientifiquement pour la sèche musculaire ?
Son efficacité dépend de sa composition précise. Les brûleurs thermogéniques contenant de la caféine et des catéchines de thé vert (EGCG) sont les mieux validés : Hursel et al. (International Journal of Obesity) montrent une augmentation de la dépense énergétique de 3-4% et une combustion lipidique accrue. Pour un sportif à 2000 kcal/jour, cela représente 60-80 kcal supplémentaires — modeste mais cumulatif sur une cure de 8-12 semaines. L'effet est amplifié par un déficit calorique et un entraînement régulier, sans lesquels aucun brûleur n'est efficace.
Le format effervescent de Lipoxyl offre-t-il une meilleure biodisponibilité des ingrédients actifs qu'une gélule classique ?
Pour certains ingrédients oui. Les formules effervescentes permettent une dissolution complète dans l'eau, facilitant l'absorption gastro-intestinale de molécules comme la caféine (pic plasmatique atteint en 30-45 min vs 45-60 min pour les gélules). L'inconvénient est la possible dégradation oxydative des ingrédients sensibles (vitamines, extraits végétaux) par rapport aux gélules hermétiques. En pratique, la différence d'efficacité est faible — l'avantage principal est la facilité de prise et la régularité d'utilisation, facteur clé dans le succès d'une cure de sèche.
Peut-on utiliser Lipoxyl en combinaison avec la L-carnitine pour maximiser la combustion des graisses pendant la sèche ?
Oui, les mécanismes sont complémentaires. Lipoxyl agit via la thermogenèse (augmentation de la dépense énergétique de base), tandis que la L-carnitine facilite le transport des acides gras vers les mitochondries pour leur oxydation. Des études (Fielding et al., Journal of Physiology) montrent que 2g/jour de L-carnitine pendant 12 semaines augmentent l'utilisation des graisses à l'effort modéré. Cette combinaison est cohérente pour une sèche active — à condition que le déficit calorique reste la pierre angulaire de la stratégie.
Combien de temps faut-il utiliser Lipoxyl pour observer des résultats visibles sur la composition corporelle ?
Les études sur les brûleurs thermogéniques montrent des effets mesurables sur la composition corporelle à partir de 8-12 semaines de cure. La perte de masse grasse additionnelle attribuable au supplément seul (vs alimentation + entraînement) est typiquement de 0,5-1,5 kg sur 12 semaines selon les méta-analyses. Pour des résultats visibles, l'alimentation contrôlée (déficit 300-500 kcal/jour), les protéines élevées (1,8-2,2 g/kg) et l'entraînement en résistance doivent accompagner la prise pour préserver la masse musculaire.
Lipoxyl peut-il perturber le sommeil ou la récupération musculaire si utilisé en phase de sèche ?
Si sa formule contient de la caféine, oui — la prise tardive est à éviter. Drake et al. (Journal of Clinical Sleep Medicine) ont démontré que la caféine consommée jusqu'à 6h avant le coucher réduit la durée et la qualité du sommeil, augmentant le cortisol nocturne. En sèche, un mauvais sommeil aggrave le catabolisme musculaire et augmente la faim — effet inverse de l'objectif recherché. La règle d'or : pas de formule caféinée après 14h, et surveiller la somme totale de caféine journalière (café + brûleur + pré-workout < 400mg).
Lipoxyl est-il adapté aux femmes pratiquant la musculation en phase de définition musculaire ?
Oui, à conditions égales de tolérance aux stimulants. Les femmes répondent aux thermogéniques de manière similaire aux hommes en termes de dépense énergétique et de combustion lipidique. Les préoccupations spécifiques aux femmes : éviter en cas de grossesse ou d'allaitement (caféine déconseillée), surveiller les interactions avec des contraceptifs hormonaux qui ralentissent le métabolisme de la caféine, et commencer par une demi-dose pour évaluer la tolérance. La stratégie nutritionnelle (protéines élevées, déficit modéré) reste plus déterminante que le brûleur lui-même pour préserver la masse musculaire en sèche féminine.
