Weight loss supplements are designed to sit alongside a calorie-controlled diet and regular training — not replace them. The range here covers everything from high-protein formulas and fat burners to capsules, powders, and metabolism-focused blends, giving you the tools to build a stack that fits your goals and your routine.
Every product is developed by Myprotein's expert nutritionists, so you know exactly what's in each formula and why. Whether you're looking for weight loss pills, a pre-workout with added fat-loss credentials, or a protein-first meal replacement, there's a format here that works.
Who Weight Loss Supplements Are For
These supplements are built for anyone who's already putting in the work — training consistently and eating with intention — and wants targeted nutritional support to go alongside it. That might mean a high-protein formula to preserve muscle while in a calorie deficit, a thermogenic capsule to factor into your pre-workout routine, or a meal replacement to keep things structured on busy days.
They're equally suited to those just getting started with fat loss supplementation and experienced athletes who know exactly what they want from their stack. The range spans multiple formats and ingredient profiles, so whether you're managing macros carefully or keeping things simple, there's an option that slots in without friction.
When to Use Weight Loss Supplements
Timing depends entirely on the format. Capsule-based fat burners and thermogenics are typically taken before training or earlier in the day. Protein-based weight loss supplements — like high-protein shakes or meal replacements — work well as a structured breakfast, a post-workout option, or a controlled evening meal. Pre-workouts with fat-loss ingredients are best taken 20–30 minutes before your session.
Consistency matters more than perfect timing. These products are most effective when used regularly as part of a calorie-controlled diet, not as a quick fix around a single session. Stack them with whole foods, stay hydrated, and treat them as one part of a broader approach — that's when you'll get the most out of them.
Weight Loss Supplements Benefits
High Protein Intake in a Calorie Deficit
Keeping protein high while cutting calories is one of the most important levers in a fat loss phase. Protein contributes to the growth and maintenance of muscle mass1, which matters when you're eating less. Supplements like high-protein shakes and meal replacements make it easier to hit targets without going over your calorie goals.
Structured Formats That Fit a Calorie-Controlled Lifestyle
Meal replacement powders take the guesswork out of portion control, giving you a measured, nutritionally complete option on days when prepping food isn't practical. Substituting two daily meals of an energy-restricted diet with meal replacements contributes to weight loss2, making these a genuinely useful tool alongside whole food meals.
B Vitamins to Keep You Going
Several weight loss supplements in this range include B vitamins — including niacin, B6, and B12 — which contribute to normal energy-yielding metabolism3 and to the reduction of tiredness and fatigue4. That's useful when you're training hard and eating in a deficit, where energy management becomes more of a daily consideration.
A Range of Formats for Every Preference
Not everyone wants to mix a shake. The range includes capsules, powders, ready-to-use liquids, and gummies — so you can pick what actually fits your lifestyle. Having the right format makes it far easier to stay consistent, and consistency is what drives results over time.

FAQs
What are weight loss supplements?
Weight loss supplements are nutritional products formulated to be used alongside a calorie-controlled diet and exercise programme. They come in a range of formats — including capsules, powders, and liquids — and typically contain ingredients like protein, B vitamins, thermogenic compounds, or specific botanical extracts. They're designed to complement your existing routine, not act as a standalone solution.
What types of weight loss supplements are available?
The range includes fat burner supplements in capsule form, high-protein shakes, meal replacement powders, pre-workouts formulated for fat loss, CLA capsules, L-carnitine, apple cider vinegar gummies, and more. There are over 20 products in this category, spanning a wide range of ingredient profiles and formats to suit different goals and preferences.
What's the difference between fat burner supplements and weight loss pills?
Fat burner supplements typically contain thermogenic ingredients — compounds like caffeine or botanical extracts — and are usually taken before training. Weight loss pills and capsules is a broader term that covers everything from fat burners to metabolism-support formulas and fibre-based products. Both fall under the weight loss supplement umbrella; the difference is largely in their specific ingredient focus and intended use case.
Which weight loss supplement should I choose?
It depends on what your routine looks like. If you train regularly and want something to take before a session, Origin Shred Pre-Workout contains choline, which contributes to normal lipid metabolism5, alongside B vitamins including niacin, B6, B12, and biotin, which contribute to normal energy-yielding metabolism3 and to the reduction of tiredness and fatigue4. If protein intake is your priority, Impact Diet Whey delivers up to 36g of protein per serving, and protein contributes to the maintenance of muscle mass1 — important when you're eating in a deficit.
Are weight loss supplements suitable for women?
Yes — the majority of products in this range are suitable for both men and women. Formats, ingredients, and serving sizes vary across the range, so it's worth checking individual product pages to find what aligns with your specific goals. There's no single "best" option; it comes down to your training style, dietary habits, and the format you're most likely to use consistently.
Can I use weight loss supplements as a meal replacement?
Protein Meal Replacement Blend is specifically formulated for this purpose. Substituting two daily meals of an energy-restricted diet with meal replacements contributes to weight loss2, and substituting one daily meal contributes to the maintenance of weight after weight loss6. It's a structured option for days when cooking isn't practical, and works best alongside at least one balanced whole food meal per day.
Who develops Myprotein's weight loss supplements?
Every product in this range is developed by Myprotein's expert nutritionists. Each formula is built around clearly defined ingredient profiles and dosages, so you know exactly what you're taking and why. The focus is on products that are practical, effective, and straightforward to incorporate into a real routine.
How do weight loss supplements fit into a calorie-controlled diet?
They work best as one component of a broader approach — not a replacement for it. High-protein formats help you hit macro targets without overrunning calories. Meal replacements bring structure to days when food prep isn't possible. Capsule-based products fit around training. The key is building a consistent routine that pairs these supplements with a calorie deficit and regular exercise.
Are these fat loss supplements available in Ireland?
Myprotein ships across Ireland and the EU, so the full weight loss supplement range is available regardless of where you're based. Product availability, formats, and delivery options can be confirmed at checkout. The range is the same — whether you're in Dublin or London, you've got access to the same formulas.
How long does it take to see results from weight loss supplements?
Results depend on diet, training consistency, and which products you're using — there's no universal timeline. Supplements work alongside a calorie deficit and regular exercise; they don't accelerate results independently of those factors. Most people find that building a consistent supplementation habit over several weeks, combined with structured training and nutrition, is when the benefits become most noticeable.
