Fat Burners stocks two types of formula: caffeine-based thermogenic capsules such as Trec Thermo Fat Burner Max and Applied Nutrition Shred X, and stim-free L-carnitine in liquids and capsules from Ultra Lyte and Trec, plus Trec CLA + Green Tea and Fat Killer.
The first decision is caffeine.
Liquid L-carnitine is measured with a cup and drunk neat or in 200 to 300 ml of water, usually 30 to 60 minutes before training. Capsules are easier to carry in a gym bag. Trec Fat Killer is a 500 ml tropical-flavoured liquid, and Trec CLA + Green Tea is a capsule built around conjugated linoleic acid.
No ingredient here has an authorised UK claim for fat loss, so treat these products as training-day extras alongside a calorie-controlled diet. They are for healthy adults only, and you should check the number of servings per pot before comparing prices. For berberine, ACV gummies and MCT powder, go back to Weight Management.
About 152 mg per serving, similar to a strong coffee. Try the 60-capsule pot first to see how you tolerate it, and avoid taking it late in the day.
No. L-carnitine on its own is caffeine-free, and Ultra Lyte L-Carnitine 3000 is labelled caffeine-free and vegan. Blends with green tea may contain some caffeine, so check the label.
The Ultra Lyte label suggests 15 ml, neat or in 200 to 300 ml of water, 30 to 60 minutes before training. One 450 ml bottle gives 30 servings.
It is not a good idea, particularly with two caffeine-containing formulas. Choose one product and follow its label dose.
Under-18s, anyone pregnant or breastfeeding, and people sensitive to caffeine. If you have a heart condition or high blood pressure, or take medication, speak to your GP or pharmacist first.
