# 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.

3\. Applied Nutrition Critical Whey Advanced

Around £30 for 825g at listed UK prices.

!Whey Protein 360 - GOLD Innovation | Whey Protein Shakes | Protein Works

4\. The Protein Works Whey Protein 360 GOLD

Good value when buying larger bags or on offer.

A practical option if keeping the ongoing cost down is your priority. Compare the actual protein delivered per serving, rather than just the size of the scoop. www.wheywise.co.uk

!Form Nutrition Performance Protein Vanilla 520g | H&B

5\. Form Nutrition Performance Protein

(Best vegan pick)

Around £27, depending on retailer.

A plant-based option for people who avoid dairy. Also worth considering if you prefer a vegan protein blend over standard whey. www.independent.co.uk

## 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

For most people in Britain, Optimum Nutrition Gold Standard 100% Whey is the best all-round choice: it provides about 24 g protein per serving, mixes well, and has consistently strong reviews.

Good alternatives:

- Best value: MyProtein Impact Whey - around 21-23 g protein per serving, with frequent discounts. - Best budget option: Applied Nutrition Critical Whey - good protein content and typically competitive pricing. - Best for cutting or lactose sensitivity: Dymatize ISO100 - a whey isolate with high protein purity and fewer carbohydrates and fats. - Best low-calorie diet option: PhD Diet Whey - designed for higher protein with a lower-calorie profile. - Best premium option: Hermosa Grass-fed Whey - praised for ingredient quality and flavour, though it is relatively expensive.

Recommendation: Buy a small bag first, choose a flavour you will actually drink, and compare prices per 25 g of protein, not merely tub price. For muscle gain, total daily protein and consistent resistance training matter more than choosing between reputable whey brands.
