# Best protein powder in the UK (2026)
My advice: choose a whey protein for everyday muscle building, a whey isolate if you want less lactose, or a plant-based blend if you avoid dairy. You don't need the most expensive tub - protein per serving, cost per 25g of protein, ingredients and taste matter more.

## Which type should you buy?
| Your goal | Best type |
|--------|--------|
| Build muscle | Whey concentrate |
| Lose fat while maintaining muscle | Whey or isolate; track calories |
| Reduce lactose intake | Whey isolate |
| Avoid dairy | Pea/soy or a blended vegan protein |
| Prefer a juice-like drink | Clear whey isolate |
## What to look for
- Protein\: aim for roughly 20-30g per serving.
- Value\: compare the cost per 25g of actual protein, not just the tub price.
- Ingredients\: avoid paying extra for unnecessary extras you don't need.
- Allergies\: whey is milk-derived; whey isolate is low in lactose but isn't guaranteed lactose-free.
For most healthy adults, protein powder is a convenience rather than a necessity. www.which.co.ukwww.wheywise.co.uk
