Weight management supplements are tools that sit alongside your training and nutrition — not replacements for either. This range covers everything from high-protein formulas and pre-workouts to metabolism-focused capsules, fibre gummies, and diet whey, giving you a broad set of options depending on where you are in your journey. Whether you're in a calorie deficit, maintaining after a cut, or simply trying to make smarter food swaps, there's something here built for that goal.
The range includes over 20 products spanning powders, capsules, snacks, and everyday staples like instant oats and all-natural peanut butter. Every product is developed by Myprotein's expert nutritionists with clear nutritional profiles, so you know exactly what you're working with — no guesswork, no filler.
Who These Are For
These products are built for people who take a considered approach to what they eat and how they train. If you're tracking macros, managing portions, or making deliberate swaps to reduce calorie intake without sacrificing nutrition, this range gives you the formats and ingredients to do that effectively. That includes anyone in an active cut, maintaining a weight loss result, or simply cleaning up their diet without overcomplicating it.
It's also a solid fit for people who train hard but want to stay lean — those who need sufficient protein to contribute to the maintenance of muscle mass1 while keeping overall calorie intake in check. If that sounds like you, you'll find products here that do exactly that job, whether you prefer a shake, a capsule, a snack, or something to cook with.
When to Use Weight Management Supplements
Timing depends on the product and your goal. High-protein shakes and diet whey work well as meal replacements or between-meal top-ups, particularly when you're keeping calories tight and want to hit your protein targets without eating a large volume of food. Pre-workout formulas like Origin Shred are designed for use before training sessions where you want to go in sharp and focused. Capsule-based products — think berberine, L-carnitine, or metabolism-support blends — typically fit best with meals, so check the label for the right timing on each.
Everyday products like instant oats and sugar-free syrups don't have a strict timing window — they're about making the meals you're already eating work harder. Swapping regular syrup for a sugar-free version or building breakfast around oats are simple, consistent habits that compound over time. The best time to use any of these products is consistently, in a routine that makes sense for how you actually live.
Weight Management Supplement Benefits
High-Protein Formats That Keep Calories in Check
Protein is the cornerstone of any sensible weight management approach. Protein contributes to the growth and maintenance of muscle mass1, and products like Impact Diet Whey and Total Protein Blend let you hit meaningful protein targets without a high calorie cost. That's a practical advantage when you're eating in a deficit and want to protect lean tissue.
Smarter Food Swaps Built Into the Range
Not every weight management tool comes in a capsule. Sugar-Free Syrup, All-Natural Peanut Butter, and Extra Protein Cookies are everyday products designed to fit into a calorie-conscious diet without making it feel restrictive. They're about making what you already eat work better, not overhauling your entire lifestyle overnight.
B Vitamins That Contribute to Normal Energy-Yielding Metabolism
Several products in this range — including Origin Shred Pre-Workout — contain B vitamins including niacin, B6, B12, and biotin, which contribute to normal energy-yielding metabolism2 and contribute to the reduction of tiredness and fatigue3. These are particularly relevant when you're training in a deficit and want to keep your nutritional bases covered.
Broad Format Range for Every Routine
Powders, capsules, gummies, snacks, and whole-food staples — the format range here means you can build a weight management stack that actually fits your day. Some people want a quick capsule with breakfast. Others want a shake that replaces a meal. Others want a protein-rich cookie that handles an afternoon craving. All of those options exist in this range.
Popular Picks

FAQs
What are weight loss supplements and how do they work?
Weight loss supplements are products — powders, capsules, gummies, snacks, and everyday food staples — formulated to work alongside a calorie-controlled diet and exercise plan. Different products serve different roles: high-protein shakes help you hit protein targets with fewer calories, pre-workouts are formulated for training sessions, and capsule products contain specific ingredients like berberine, L-carnitine, or chromium. None of these are magic solutions — they're tools that complement solid nutrition and training habits.
What weight loss supplements are available at Myprotein Ireland?
Myprotein's weight management range includes over 20 products, from Impact Diet Whey and Total Protein Blend to Berberine Capsules, Liquid L-Carnitine Capsules, Metabolism + Glucose Support Capsules, High Fibre Gummies, and Sugar-Free Apple Cider Vinegar Gummies. Everyday products like 100% Instant Oats, All-Natural Peanut Butter, and Sugar-Free Syrup are also part of the range — practical swaps that make a calorie-conscious diet easier to maintain long-term.
What's the difference between fat loss supplements and diet protein shakes?
Fat loss supplement capsules tend to contain specific active ingredients — things like berberine, chromium, or L-carnitine — and are taken in a targeted way, typically with meals. Diet protein shakes like Impact Diet Whey are food products first: they provide protein, which contributes to the maintenance of muscle mass1, with a lower calorie profile than a standard mass gainer or meal. They often work best as a meal component or between-meal option when you're managing total calorie intake.
Which weight management supplement do you recommend for someone just getting started?
Impact Diet Whey is a strong starting point for most people — it's a straightforward high-protein shake with a clean nutritional profile, and protein contributes to the growth and maintenance of muscle mass1. If you're looking for a pre-workout specifically designed for a shred phase, Origin Shred Pre-Workout contains choline, which contributes to normal lipid metabolism4, alongside B vitamins that contribute to normal energy-yielding metabolism2 and contribute to the reduction of tiredness and fatigue3.
Are slimming supplements safe to use with other products in the range?
Most products in this range are designed to be used alongside each other — a pre-workout before training, a protein shake post-session, and capsule products with meals are a common combination. That said, always read the label for each product and follow the recommended serving guidance. If you're taking prescribed medication or have an underlying health condition, speak to a healthcare professional before adding new supplements.
How many products are in the weight management range at Myprotein?
There are over 20 products in the weight management range, covering multiple categories: protein powders, pre-workouts, capsules, gummies, high-protein snacks, and everyday food products. That breadth means you can build a full approach — not just a single supplement — across different parts of your day and diet.
Who develops Myprotein's weight management products?
Myprotein's weight management products are developed by Myprotein's expert nutritionists. Every formula is built around clear nutritional data and specific ingredient inclusions, so you know exactly what you're getting per serving and why it's in there.
Do any of the weight management products contain chromium?
Yes — Metabolism + Glucose Support Capsules and some other products in the range contain chromium. Chromium contributes to normal macronutrient metabolism5 and contributes to the maintenance of normal blood glucose levels6. These are factual, EU-authorised roles for chromium as a trace mineral, and the products are formulated to provide meaningful amounts per serving.
Are there high-fibre products in the weight management range?
High Fibre Gummies are specifically included in the range for people looking to increase their daily fibre intake in a convenient format. Beyond that, 100% Instant Oats is a naturally high-fibre whole food option that fits easily into a structured diet. Fibre is a useful component of a weight management approach because it contributes to normal bowel function and helps you build meals with more volume relative to calories.
Can weight management supplements be used as meal replacements?
Some products in this range are suitable for use as part of a meal replacement approach — Impact Diet Whey, for example, provides a high-protein, lower-calorie option that many people use in place of a meal when eating in a deficit. It's worth noting that EU guidelines recognise that substituting two daily meals of an energy-restricted diet with meal replacements contributes to weight loss7, and substituting one daily meal contributes to the maintenance of weight after weight loss8. Always follow serving guidance and ensure your overall diet remains nutritionally complete.
