1. Optimum Nutrition Gold Standard — Best Overall
The industry benchmark for protein powder — 24g protein per serving, outstanding taste across 20+ flavours, and mixability that beats most competitors. Third-party tested for quality and banned substances. Consistently top-ranked across dietitian and athlete reviews worldwide. Available throughout Europe at ~€0.70 per serving. The reliable choice for most people.
- 24g protein per serving — consistent quality
- Outstanding taste and mixability
- Third-party tested and verified
- ~€0.70/serving — competitive price
- Whey concentrate blend — not ideal for lactose sensitivity
- Not as high protein per serving as isolate options
2. Transparent Labs 100% Whey Isolate — Best for Athletes
28g protein per serving — the highest in this comparison. Fully published third-party testing on every batch, zero artificial additives, and sourced from grass-fed whey. Top pick from multiple 2026 dietitian roundups for ingredient transparency. Ideal for athletes who track everything and want maximum protein with minimal processing. ~€1.10/serving.
- 28g protein per serving — highest here
- Full third-party testing transparency

- Grass-fed whey source
- Premium price at ~€1.10/serving

3. Dymatize ISO100 Hydrolyzed — Best for Fast Recovery
Hydrolyzed whey protein is pre-digested — broken into smaller peptides for the fastest possible absorption rate. 25g protein per serving, minimal fat and carbohydrates, and the Fruity Pebbles flavour is consistently among the top-rated protein flavours in any category. Ideal for post-workout windows when fast nutrient delivery matters. ~€1.00/serving.

4. Garden of Life Sport Organic — Best Vegan
30g protein from a certified organic pea, rice, and sprouted grain blend — the highest plant protein count in this comparison. USDA Certified Organic, NSF Certified for Sport (meaning tested for banned substances). Complete amino acid profile without synthetic additives. Best-in-class plant protein for athletes who require sport certification. ~€1.30/serving.

5. Myprotein Impact Whey — Best Budget
21g protein at approximately €0.40 per serving — the lowest cost per serving by a wide margin. Quality is solid for the price: good mixability, 100+ flavour options, and regular testing. The go-to option when cost matters most. Whey concentrate formula is adequate for daily protein supplementation. Bulk discounts reduce cost further during promotions.

What to Look for in a Protein Powder
Protein type: concentrate vs isolate vs hydrolyzed
Whey concentrate contains 70–80% protein with some fat and lactose. Whey isolate is processed to 90%+ protein with minimal fat and lactose — better for those with mild dairy sensitivity. Hydrolyzed whey is pre-digested for the fastest absorption — useful around workouts but more expensive. For most people, concentrate or isolate covers daily needs effectively.
Protein per serving
Aim for 20–30g protein per serving. Products listing impressive percentages can be deceiving — check absolute grams per 30g serving. Transparent Labs leads at 28g; Myprotein Impact Whey provides 21g. Supplement labels vary in serving sizes, so always compare per 100g or per standardised serving.
Third-party testing
NSF Certified for Sport or Informed Sport certification means the product has been independently tested for banned substances — important for competitive athletes. Transparent Labs and Garden of Life carry these certifications. Optimum Nutrition has a strong quality track record but without independent per-batch certification.
Plant protein considerations
A single plant source rarely provides a complete amino acid profile. Pea protein is high in leucine but low in methionine. Rice protein is the opposite. Combining pea + rice (as Garden of Life does) creates a complete profile comparable to whey. Look for combinations rather than single-source plant proteins.
Our Verdict
For most people, Optimum Nutrition Gold Standard remains the best all-round protein powder — proven quality, outstanding taste, and competitive pricing at €0.70/serving. Serious athletes prioritising ingredient transparency should choose Transparent Labs Whey Isolate. Vegan athletes need Garden of Life Sport Organic — the only certified, complete plant protein on this list. Budget-first? Myprotein Impact Whey at €0.40/serving is unbeatable on cost.
