Protein Powder Buying Guide (UK Edition)

Choosing the right protein powder can make a real difference to your training, health, and wallet. Here’s everything you need to know before you buy.

Decide on the Type
Whey: Fast-absorbing and complete in amino acids. Ideal for muscle gain, but not suitable for vegans or those with dairy allergies.
Plant-Based: Great for vegans or people sensitive to dairy. Look for blends (pea, rice, hemp) for a complete amino acid profile.
Casein: Slow-release, best for bedtime or long periods without food.
Other Types: Egg, beef, or collagen proteins offer specialty benefits.
Know Your Protein Needs
General guideline: 1.2–2g protein per kg of bodyweight daily for active adults.
Use a powder to “top up” what you don’t get from whole foods.
If you’re new to protein, start with small tubs to test tolerance and taste.
Check Flavour & Sweeteners
UK protein powders range from natural to dessert-inspired flavours. Read reviews for texture, mixability, and aftertaste.
Avoid too much artificial sweetener if you have a sensitive gut.
Price vs. Value
Calculate cost per serving, not just price per tub—bulk bags can offer better value but check for freshness guarantees.
Don't overpay for exotic ingredients you won’t use.
Common Mistakes to Avoid
Buying “mass gainers” when you want a pure protein (they contain lots of carbs and sugar).
Not checking allergen info (whey and casein = milk; many blends = soya or gluten traces).
Forgetting to store your powder in a cool, dry place to avoid clumping.

Pro Tips

For weight loss, use unflavoured or natural sweetener blends to save on sugar/calories.
Always compare protein content per 100g and per serving—don’t be fooled by scoop size.
Read recent reviews—brands occasionally change recipes or suppliers!
Check for UK/EU certifications if quality and safety is a concern.
Mix your protein with water, not just milk, to test flavour and digestion.
If you struggle with bloating, try an isolate or hydrolysed protein.
