Fat burner tablets and capsules are one of the most searched-for categories in weight management — and for good reason. These are concentrated formulas built around specific ingredients, from plant-based caffeine and berberine to CLA and L-carnitine, designed to sit alongside a calorie-controlled diet and a consistent training routine. Whether you're looking for fat burning supplements to take before a session or something to use throughout the day, the range here covers a variety of formats and ingredient focuses.
Fat burner supplements aren't a shortcut — they work hardest when the fundamentals are already in place. Think of them as part of a broader toolkit: diet, exercise, sleep, and then supplementation layered on top. The range spans capsules, tablets, powders and liquids, so there's something to fit most preferences and routines.
Who Fat Burners Are For
Fat burner tablets and fat burner capsules are typically used by people who are already training regularly and eating in a calorie deficit, but want to add an extra layer to their routine. That might be someone cutting ahead of a physique goal, a regular gym-goer who wants to make the most of their morning sessions, or someone who simply prefers to get certain ingredients — like caffeine or CLA — in a straightforward, concentrated format rather than from food alone.
These supplements aren't exclusively for athletes or serious lifters. Plenty of people use them as part of a general active lifestyle, particularly those who want to stay sharp and focused during a period of lower calorie intake. If you're new to fat burning supplements, starting with a single-ingredient option — like a caffeine tablet or an L-carnitine formula — is a sensible way to understand how your body responds before moving on to multi-ingredient formulas.
When to Use Fat Burners
Timing depends largely on the ingredients in your chosen formula. Caffeine-containing fat burner supplements are most commonly taken 30–60 minutes before training, or earlier in the day when focus and alertness matter most. Taking caffeine-based products too late in the day can interfere with sleep, so morning or early afternoon use tends to work best for most people.
Non-stimulant options — including CLA capsules and L-carnitine — are typically taken alongside meals, making them easier to build into an existing routine. Multi-ingredient thermogenic supplements may have their own specific timing guidance, so it's always worth checking the label for the recommended intake. Consistency matters more than perfect timing: taking your chosen fat burner capsules at the same point each day makes it easier to track what's working.
Fat Burners Benefits
A Range of Ingredient Approaches
The fat burner category isn't one-size-fits-all. Some formulas are built around stimulants like caffeine, which is known to affect adenosine receptors and is widely used by people who train. Others focus on non-stimulant compounds like CLA — an omega-6 fatty acid — or amino acid derivatives like L-carnitine. Berberine is another ingredient that's gained significant attention, with 500mg per capsule in Berberine Capsules making it easy to get a meaningful dose.
Flexible Formats
Fat burner supplements come in capsules, tablets, liquids, and powders across this range, so you're not locked into one format. Liquid L-Carnitine Capsules offer a different texture and absorption profile compared to a straight tablet, while powders like 100% L-Tyrosine can be mixed into other drinks. That flexibility makes it easier to fit supplementation around your existing stack.
Stackable with Other Supplements
Fat burners are commonly used alongside protein supplements and other weight management tools. Many people pair a thermogenic supplement like Thermopure with their existing protein intake, or use caffeine tablets alongside a pre-workout on heavier training days. The key is being mindful of total caffeine intake across your full stack — especially if multiple products contain stimulants.
Chromium-Containing Options
Some fat burner formulas include micronutrients alongside their primary ingredients. Berberine Capsules, for example, provide 40µg of chromium per capsule — 100% of the daily NRV — and chromium contributes to normal macronutrient metabolism1 and the maintenance of normal blood glucose levels2.
Popular Picks

FAQs
What are fat burner tablets and how do they work?
Fat burner tablets are concentrated supplement formulas containing ingredients like caffeine, CLA, L-carnitine, berberine, or green tea extract, typically taken alongside a calorie-controlled diet and training plan. Different ingredients work through different mechanisms — caffeine, for instance, is a stimulant compound that acts on adenosine receptors, while CLA is an omega-6 fatty acid found naturally in dairy and meat. No fat burner replaces a calorie deficit; they're designed to complement solid diet and exercise habits.
What fat burning supplements are available at Myprotein?
The range includes 14 products across multiple formats: capsules, tablets, liquids, and powder. Popular options include Berberine Capsules (500mg berberine + 40µg chromium per capsule), CLA Capsules (1000mg omega-6 per serving), Thermopure, Green Tea Extract Plus Tablets, Liquid L-Carnitine Capsules, Pure Caffeine Tablets, and 100% L-Tyrosine Powder, among others. That breadth means you can opt for a single-ingredient approach or a more comprehensive multi-ingredient formula depending on your preference.
What's the difference between stimulant and non-stimulant fat burner supplements?
Stimulant-based fat burner capsules and tablets typically contain caffeine — either from pure caffeine or plant sources like green tea — and are best taken earlier in the day to avoid disrupting sleep. Non-stimulant options, such as CLA Capsules or L-Carnitine Tablets, don't contain caffeine and can generally be taken at any time, including in the evening. If you're sensitive to caffeine or already using a pre-workout, a non-stimulant fat burner supplement is often the more practical choice.
Are fat burner capsules suitable for vegetarians or vegans?
Suitability varies by product, so checking the individual product page is always the best approach. Some capsule shells are made from gelatine, which isn't suitable for vegetarians, while others use plant-based capsule materials. Tablet formats and powders like 100% L-Tyrosine Powder tend to have simpler ingredient lists. The product pages include full ingredient and allergen information to help you choose.
Which fat burner should I choose?
Green Tea Extract Plus Tablets are a strong starting point if you want a plant-based caffeine source — caffeine is a stimulant compound widely used before training sessions, and the tablets offer a clean, easy-to-dose format. For a stimulant-free option, CLA Capsules deliver 1000mg of omega-6 fatty acid per serving and are one of the most established ingredients in the category. If you want something with added micronutrient support, Berberine Capsules provide 100% of the daily NRV for chromium, which contributes to normal macronutrient metabolism1.
Can I take fat burner tablets with other supplements?
Many people use fat burner supplements alongside protein shakes, pre-workouts, and other daily supplements. The main consideration is total caffeine intake — if your pre-workout already contains caffeine, adding a stimulant fat burner on top could push your daily intake higher than intended. Non-stimulant options like CLA Capsules or L-Carnitine Tablets stack cleanly with most other supplements without that concern. Always check the labels of everything in your stack.
Are these fat burner supplements suitable for use in Ireland?
Myprotein ships to Ireland, and the fat burners range — including fat burner capsules, tablets, and powders — is available to customers there. The product formulations meet EU standards, and all labelling follows EU regulations. Whether you're searching for fat burners in Ireland or weight loss supplements for use alongside a calorie-restricted diet, the full range is accessible via the Myprotein website.
Who develops the fat burner supplements at Myprotein?
Myprotein's expert nutritionists develop the formulations across the fat burners range. Each product is created with specific ingredient profiles and dosages in mind, and the team works to ensure that what's on the label accurately reflects what's in the product. That focus on formulation integrity is part of what's made Myprotein one of the most recognised names in sports nutrition.
How long does it take to see results from fat burning supplements?
Fat burning supplements don't produce results in isolation — outcomes depend on diet, training consistency, sleep quality, and overall calorie intake. There's no standard timeframe that applies to everyone. Most people who use fat burner tablets or capsules are already following a structured plan; the supplements are one component of that approach, not a standalone solution. Tracking your diet and training alongside supplementation gives you the clearest picture of what's contributing to your progress.
What's the difference between thermogenic supplements and other fat burners?
Thermogenic supplements are a subcategory of fat burners that specifically contain ingredients associated with heat production or stimulant activity — caffeine is the most common. Thermopure is an example of a multi-ingredient thermogenic formula within the range. Other fat burner supplements, like CLA Capsules or L-Carnitine Tablets, aren't thermogenic in the traditional sense — they work through different mechanisms entirely and don't rely on stimulant ingredients.
