1. PhenQ

PhenQ by Wolfson Brands Limited takes the lead on our list with its specially designed formula that promises to naturally improve weight loss by up to 5X. It does this by fully supporting thermogenesis, leaving you with increased metabolisms and better energy levels by helping your body convert those pesky stored fats into energy. But that's not all, the vegan-friendly formula also claims to reduce food cravings and prevent future fat accumulation while supporting prolonged fat burning 48 hours after workouts, maximizing your exercise efforts.


  • All natural, vegan/vegetarian-friendly formula makes the product more inclusive.
  • Uses only 6 ingredients in approved doses—lowered side effect rate.
  • Helps the body respond better to diet and exercise regimens.
  • Offers a significant improvement in your weight loss progress.
  • Prevents future fat accumulation and converts stored fat into energy.


  • Only available on their official website (which is how they avoid counterfeit).
  • The presence of caffeine in the formula may not be suitable for sensitive users.


Unlike other fat burners or weight management aids that use an extensive list of ingredients to accelerate weight loss, PhenQ uses just 6. These 6 ingredients have some strong scientific research backing their use which matches up with the claims made by PhenQ. A-Lacys Reset, for example, has been proven to support two primary effects needed for fat elimination—thermogenesis and fat metabolism. It also contains a healthy dose of L-Carnitine which helps your body lose excess fat by transforming stored fat into energy.

Customer Reviews

PhenQ boasts numerous 5-star reviews, with many sharing positive experiences outlining PhenQ's ability to tackle stubborn fat. Most reviews highlight its ability to support weight loss in short time frames, but it should be noted that none of these notable results came without a combination of diet and exercise. There was also mention of its positive effect on energy and fatigue, which is always welcomed in weight loss journeys.

Why Buy PhenQ

PhenQ stands out from the crowd with its muti-method approach and formula, which produces balanced effects that are potent enough to eliminate stubborn fat without inducing side effects. It also stops the body from forming new fat cells and fuels a 48-hour burn, which simply means your body continues burning fat after your exercise routine is over. If that's not reason enough to buy PhenQ, the expert blend also improves moods while eliminating mental and physical fatigue, this will keep you motivated and full of energy, ensuring you don't hit any plateaus.

2. Capsiplex Trim

Another giant Wolfson Brands is Capsiplex Trim, a weight loss supplement that focuses on fat elimination in women. The all-natural formula claims to balance blood sugar and hormone levels while bridging nutritional gaps left by some diets. This leaves you with fewer cravings, healthier eating patterns, and ultimately fat loss without setbacks. Let's not forget the promise of thermogenesis activation—enhanced metabolisms for higher calorie burns and energy levels on training and non-training days. The formula also claims to safeguard hard-earned muscle gains by shedding fat around muscles while passively supporting muscle development.


  • Vegan-friendly and GMO, chemical, soy, gluten, and dairy-free.
  • Natural metabolisms and energy paired with reduced cravings.
  • Works when the body is in active and resting mode, which ensures maximum fat elimination.
  • Maintains muscle mass and promotes muscle functionality and development.


  • Must be used with diet and exercise for noticeable results.
  • It may not be suitable for those sensitive to caffeine.


Trim has a jam-packed ingredient list that has just over a dozen components. But two ingredients from this list that caught my attention were Capsimax and InnoSlim. Capsimax helps the body burn more calories and curb hunger pangs, while InnoSlim, increases adiponectin, a hormone responsible for supporting our body's fat-burning processes, which is a definite plus. 

Full list of ingredients includes:

  • B Vitamins (B6 and B9)
  • Vitamin C
  • Vitamin D
  • Iron
  • Zinc
  • Calcium
