What Are Protein Powders, Shakes & Supplements?

Protein powders and shakes are concentrated sources of protein that can be mixed with water, milk or plant-based alternatives to create a quick, easy drink. They are commonly made from whey, casein, egg, soy, pea, rice or blended plant proteins. Protein supplements also come in the form of ready-to-drink shakes, bars, cookies and capsules.

The goal of protein supplementation is simple: help you reach an optimal daily protein intake to support muscle maintenance, recovery after training, weight management and overall health. They are especially useful if you train regularly, follow a busy lifestyle, or prefer a convenient alternative to preparing high-protein meals.

Why Are Protein Powders & Shakes Important for Health & Fitness?

Protein is a key macronutrient for muscle maintenance, immune function, hormone production and tissue repair. If you train regularly, follow a calorie-restricted diet, are ageing, or follow a plant-based diet, your daily protein needs can be higher than average. Protein powders and shakes help you bridge the gap between food intake and your optimal requirement.

Used correctly alongside a balanced diet and training plan, protein supplements can:

• Support muscle mass and strength.
• Help limit muscle breakdown during weight loss phases.
• Assist with recovery after intense exercise.
• Provide a practical, high-protein snack when you’re on the go.

If you are looking to gain muscle specifically, you can combine protein with targeted products from our Weight Gainers & Muscle Mass Gainers collection.

How to Use Protein Powders, Shakes & Supplements Safely

Always follow the serving instructions on the product label and consider your overall diet and training routine. General tips include:

• Post-workout: Mix one serving of protein powder with water or milk within 30–60 minutes after training to support recovery.
• Between meals: Use a shake as a high-protein snack to keep you fuller for longer.
• Before bed: Casein-based products may be taken in the evening for slower-release amino acids.
• Hydration: Drink enough water throughout the day, especially if using protein in combination with creatine or pre-workouts.

To make mixing easier and achieve a smoother texture, pair your powder with one of our Protein Shakers & Supplement Bottles. For ideas on combining training and nutrition for performance, you can also read our sports performance blog, such as How to Improve VO2 Max: Tips and More.

FAQs about Protein Powders, Shakes & Supplements

How much protein do I need per day?

Protein needs vary depending on your age, body weight, activity level and goals. People who train regularly or are trying to build or maintain muscle often require more than those who are less active. A registered nutritionist or healthcare professional can help you work out a personalised target.

Is whey protein better than plant-based protein?

Whey protein is rich in essential amino acids and is quickly absorbed, making it a popular choice for post-workout use. Plant-based proteins can be just as effective when they provide a complete amino acid profile, especially when blends of different plant sources are used. The best option depends on your diet, digestion and personal preferences.

Can I use protein shakes for weight loss?

Protein shakes can support a weight management plan by helping you feel fuller for longer and protecting lean muscle when you are in a calorie deficit. However, they should be used as part of a balanced diet and healthy lifestyle, not as a sole source of nutrition, unless specifically formulated as a complete meal replacement and used under guidance.

Are protein powders safe to take every day?

For most healthy adults, using protein powders daily within recommended serving sizes is considered safe. It is important to factor in protein from food and not exceed sensible intake levels. If you have kidney, liver or other health conditions, speak to your doctor before using protein supplements regularly.

When is the best time to drink a protein shake?

Many people find it useful to have a protein shake within an hour after training, when muscles are particularly receptive to nutrients. Others prefer to use protein between meals or in the evening. The best time is the one that helps you reach your total daily protein target consistently.

Can teenagers use protein powders?

Teenagers can usually meet their protein requirements through a balanced diet. In some cases, a healthcare professional may advise a supplement, particularly for those involved in intensive sports. It is important that any use of protein supplements in younger people is discussed with a doctor or dietitian.

Do I need protein supplements if I already eat a high-protein diet?

If you can consistently reach your protein target from whole foods alone, you may not need a supplement. Protein powders and shakes are mainly for convenience – they help you hit your total intake more easily on busy days or around training sessions.

Can I combine protein powder with other supplements like creatine or pre-workouts?

Yes, many people successfully combine protein powders with other sports supplements such as creatine, pre-workouts or amino acids. Always follow the directions on each product, avoid exceeding recommended doses, and consider any underlying health conditions or medications. If in doubt, seek advice from a healthcare professional.
