Shop Dietary Supplements at Myprotein

Dietary supplements are a practical way to fill the gaps between what you eat and what your training demands. Whether you're chasing strength, endurance, or simply staying consistent with your nutrition, this range brings together everything from high-quality protein powders to creatine — all developed to slot into your routine without fuss.

Every product here is built around real ingredients at meaningful amounts. The range spans gym supplements in multiple formats — powders, ready-to-mix blends, and flavoured options — so whether you prefer shaking things up post-workout or keeping it simple before a session, there's something that fits.

Who These Dietary Supplements Are For

These workout supplements are designed for people who take their training seriously — not necessarily elite athletes, but anyone who shows up consistently and wants their nutrition to match that effort. If you're lifting, running, or competing in something that demands more from your body, this range is built with you in mind.

That said, you don't need to be deep into sport to get value here. People who are simply active and want to make sure they're hitting their protein intake, or who want to explore sports nutrition supplements for the first time, will find accessible options across the range. From beginner-friendly whey proteins to more specific performance-oriented formulas, the breadth here means you can start where you are and build from there.

When to Use These Gym Supplements

Timing depends on the product and your goal. Protein powders are commonly taken immediately after training — protein contributes to the growth and maintenance of muscle mass¹, making that post-session window a natural moment to get your intake in. Creatine, on the other hand, is less about timing and more about consistency — taking 3g daily is what matters for it to increase physical performance in successive bursts of short-term, high intensity exercise².

Some people prefer to use protein powders as a convenient between-meal option when whole-food sources aren't practical — at the desk, between back-to-back sessions, or on the go. The key is making these sports supplements a consistent part of your wider nutrition plan rather than treating them as a one-off fix.

Dietary Supplement Benefits

Quality Protein to Hit Your Daily Target

Getting enough protein from food alone isn't always realistic. Powders like Impact Whey Protein and Clear Whey Protein make it straightforward to hit your daily protein target — with up to 23g per serving, they're a clean, convenient source that contributes to muscle mass growth and maintenance¹.

Scientifically Backed Creatine

Creatine monohydrate is one of the most researched fitness supplements available. At 3g per serving, Impact Creatine delivers a dose that increases physical performance in successive bursts of short-term, high intensity exercise² — no loading protocols required, just daily consistency.

Range of Formats to Suit Your Routine

Not everyone wants the same thing from their sports nutrition supplements. This range covers classic whey, isolate, mass gainer, and clear whey formats — so whether you're managing calories carefully or looking to pack in more, there's a format that makes sense for your approach.

Informed Choice Certified Options

For athletes who are tested, quality assurance matters. Clear Whey Protein Powder carries Informed Choice certification, meaning it's been batch-tested for banned substances — giving you confidence alongside the nutrition.

FAQs

What are dietary supplements?

Dietary supplements are concentrated sources of nutrients or other substances — such as protein, creatine, or vitamins — presented in formats like powders, capsules, or drinks. They're designed to complement your existing diet, not replace it. Most people use them to make hitting specific nutritional targets more practical around a busy schedule or high training load.

What gym supplements are available at Myprotein?

The range includes whey protein in multiple formats (standard, isolate, clear, and mass gainer), creatine monohydrate, and a creatine and electrolyte blend. Products come in a wide variety of flavours and serving sizes, so there's flexibility whether you're buying for the first time or stocking up on a staple.

What's the difference between whey protein and whey isolate?

Whey protein is derived from milk during cheese production and contains a mix of proteins, carbohydrates, and fats. Whey isolate undergoes additional filtration to increase the protein content per serving while reducing fats and carbohydrates — making it a leaner option. Impact Whey Isolate Powder goes through this extra processing step, which is why it's often preferred by those watching their overall calorie intake while keeping protein high.

Which workout supplement should I choose if I'm new to sports nutrition?

Impact Whey Protein Powder is a solid starting point — it delivers up to 23g of protein per serving at just 114 calories, making it straightforward to work into your daily routine. It's versatile, available in a wide range of flavours, and covers the basics without overcomplicating things. Once you've got protein dialled in, creatine is a natural next step given the strength of evidence behind it.

What is creatine and how is it used?

Creatine is a naturally occurring compound found in muscle tissue, and creatine monohydrate is the most studied form used in sports nutrition supplements. A daily intake of 3g is the threshold at which creatine increases physical performance in successive bursts of short-term, high intensity exercise². It's most commonly taken as an unflavoured powder mixed into water or a shake, and consistency matters more than timing.

What is clear whey protein?

Clear Whey Protein Powder is made from hydrolysed whey protein isolate, which gives it a light, juice-like texture rather than the thick, creamy consistency of traditional protein shakes. Each serving delivers 20g of protein¹ and it carries Informed Choice certification — batch-tested for banned substances. It's a popular choice for people who find standard whey powders too heavy, particularly in warmer weather.

Are these sports nutrition supplements batch-tested?

Clear Whey Protein Powder is Informed Choice certified, meaning each batch is independently tested for substances prohibited in sport. For athletes subject to drug testing, this level of third-party verification provides an important layer of confidence on top of the nutritional profile.

Who develops the supplements in this range?

All products in this range are developed by Myprotein's expert nutritionists, who work to ensure each formula is built around meaningful ingredient amounts and practical formats. The focus is on delivering products that are straightforward to use and grounded in nutritional science.

What is a mass gainer and who is it for?

A mass gainer is a high-calorie supplement that combines protein and carbohydrates in a single serving. Impact Whey Mass Gainer is designed for people who have a high daily calorie requirement and find it difficult to meet that through food alone — particularly those in a structured training phase focused on increasing body weight and muscle mass¹. It's a practical option when whole foods can't fill the gap.

Can I use these fitness supplements alongside a regular diet?

These fitness supplements are designed to sit alongside a balanced diet, not replace it. Whole foods remain the foundation of any solid nutrition plan — supplements fill specific gaps where convenience or volume makes it impractical to rely on food alone. Using protein powders and creatine as part of a broader nutrition strategy is the approach most athletes take.

1. Protein contributes to the growth and maintenance of muscle mass.
