Protein powder is a convenient way to increase daily protein intake to support muscle repair, growth, and recovery. Training creates small tears in muscle fibres, and protein provides the amino acids your body needs to rebuild stronger muscle.
If your diet doesn’t provide enough protein, recovery can slow down and progress can stall. Protein powders make it easier to hit your targets without unnecessary extra calories and carbs.
Protein Powder Supplements: FAQs & Buying Guide
What is protein powder and what does it do?
Protein powder is a concentrated source of protein (such as whey, casein, or plant protein) that helps you meet daily protein needs. It supports:
- Muscle repair after training
- Muscle growth when paired with resistance training
- Recovery between sessions
- Convenient daily nutrition for busy lifestyles
When should I take protein powder?
Protein powder can fit into your routine in several goal-driven ways:
- Pre-workout: Helps prep muscles if you train early or have long gaps between meals.
- Post-workout: Many people aim for a serving within 30–60 minutes after training.
- Daily nutrition: Use it to reach protein targets via smoothies, yoghurt, oats, or baking.
- Night-time recovery: Slow-release proteins can support overnight recovery while you sleep.
The best time is the time you’ll consistently use it. Total daily protein intake matters most.
Which protein powder is best for muscle growth?
The best protein powder for muscle growth depends on your digestion, diet preference, and timing:
- Whey Protein Isolate (WPI): Fast-absorbing and lean (low carbs/fats) — ideal post-workout.
- Whey Protein Concentrate (WPC): Creamy and great for everyday use, with slightly more carbs/fats.
- Plant Protein: Vegan-friendly option from pea, seeds, nuts etc. Great for dairy-sensitive users.
- Casein: Slow-digesting “night protein” for sustained amino acid release overnight.
Whey isolate vs whey concentrate: what’s the difference?
| Whey Protein Isolate (WPI) | Whey Protein Concentrate (WPC) |
|---|---|
| Typically higher protein % per serve | High protein, with slightly more carbs & fats |
| Lower lactose (often easier on digestion) | Contains more naturally occurring whey compounds |
| Common choice for lean goals & post-workout | Popular everyday protein for taste/texture |
| Often more “lean” for calorie tracking | Often more cost-effective per tub |
Is plant protein as good as whey?
Yes — plant protein powders can be highly effective for muscle recovery and growth, especially when they combine multiple sources (e.g. pea + seed proteins) to create a strong amino acid profile.
Plant protein is ideal if you’re vegan, vegetarian, or sensitive to dairy. Some formulas also include digestive enzymes and probiotics to support gut comfort and absorption.
What is casein protein and why take it at night?
Casein protein is a slow-digesting protein that releases amino acids gradually, making it a popular choice for overnight muscle recovery.
Unlike whey (fast-absorbing), casein provides a steady supply of protein during longer periods without food. Some “night protein” blends also include calming ingredients to support a restful routine.
How much protein do I need per day?
Protein needs vary based on body weight, activity level, and goals (maintenance, fat loss, or building muscle). A simple approach is to use protein powder to help you consistently reach your daily target.
If you want, you can add your goal and body weight and we’ll recommend a practical daily target and shake timing.
How do I choose the best protein powder for my needs?
Use this quick guide:
- Lean / low-carb goals: Choose WPI.
- Everyday protein + taste: Choose WPC.
- Dairy-free / vegan: Choose plant protein.
- Overnight recovery: Choose casein (night protein).
For best results, pair your protein powder with progressive training, adequate sleep, and a balanced diet.
