Fat Burners

Fat Burners holds 15 cutting-phase products in our sports range: caffeine-based thermogenic formulas such as Trec Thermo Fat Burner Max, Trec Clenburexin, Applied Nutrition Shred X and DY BlackBomb, plus stimulant-free L-carnitine liquids, capsules and Snap sugar-free gummies, and Trec CLA + Green Tea.

Read the caffeine figure first

Most capsules here are stimulant formulas, and caffeine per serving is the number that matters most when comparing them:

  • Trec Clenburexin: 220mg caffeine per serving, with green tea extract, L-tyrosine, yerba mate, green coffee, ginger, cayenne and black pepper extracts.
  • Trec Thermo Fat Burner Max: about 152mg caffeine per serving from guarana, with L-carnitine, green tea and green coffee.
  • Applied Nutrition Shred X: caffeine with L-tyrosine, L-theanine and green tea in 90 vegan capsules.

The European Food Safety Authority considers single doses of up to 200mg of caffeine, and up to 400mg a day from all sources, of no safety concern for healthy adults. A Clenburexin serving is above that single-dose figure on its own, so leave out coffee and pre-workout around it and keep it to earlier in the day.

Stim-free choices: L-carnitine and CLA

L-carnitine and CLA have no authorised health claims, so they are sold on what they contain rather than what they do. Applied Nutrition L-Carnitine 3000mg Liquid gives 3000mg per 15ml cap, adds green tea extract and vitamin C (which contributes to the reduction of tiredness and fatigue) and is vegan and halal certified. Trec offers L-Carnitine 3000 as liquid or capsules, and Snap L-Carnitine Gummies suit anyone who would rather chew than measure. Blends with green tea can still contain some caffeine.

Pack sizes

Thermo Fat Burner Max comes in 60 and 120 capsules with the same formula. Buy the 60 first to see how the caffeine suits you. For the wider cutting picture, go back to Weight Management.

Fat Burners: your questions answered

Which fat burner has the most caffeine?

Of the products whose caffeine is shown on our pages, Trec Clenburexin has the most at 220mg per serving, followed by Trec Thermo Fat Burner Max at about 152mg. Check the labels of Shred X and BlackBomb for their figures.

Should I buy Thermo Fat Burner Max in 60 or 120 capsules?

Start with 60. The formula is identical, so once you know you tolerate about 152mg of caffeine per serving, the 120 tub is the better value.

Are L-carnitine gummies an alternative to liquid?

Yes, if you prefer chewing to measuring. Snap's sugar-free blueberry gummies come 60 to a tub, while liquids such as Applied Nutrition's give 3000mg per 15ml serving, so compare the label amounts.

Can I take a fat burner with a pre-workout?

Not a caffeine-based one, because the caffeine from both adds up. On pre-workout days, choose a stim-free L-carnitine product or skip one of the two.

Which fat burners are vegan?

Applied Nutrition Shred X comes in vegan capsules, and Applied Nutrition L-Carnitine 3000mg Liquid is vegan and halal certified. Other capsules may use gelatine shells, so check the label.
