1. Know Your Fitness Goals
Start with your outcome in mind. If you are focused on muscle gain, look for higher protein per serving and complete protein sources such as whey isolate. For weight management, consider lower-calorie blends with minimal sugar. For general wellbeing, a balanced option with added vitamins and minerals can fit the bill. Vegan or dairy-free diets are well served by pea, soy, brown rice or mixed plant proteins.
2. Check the Ingredients List Carefully
Shorter ingredient lists are usually a positive sign. Watch for bulking agents, excess thickeners and artificial colours. If you prefer natural flavouring, look for products that specify natural flavours, cocoa powder or vanilla extract rather than vague flavour blends. Be mindful of allergens such as milk, soy and nuts.
3. Compare Protein Quality and Type
Whey isolate tends to provide more protein and fewer carbs per serving than whey concentrate. Casein digests more slowly, which some people prefer before bed. Plant proteins can be excellent, especially when blended to cover all essential amino acids. Check for a complete amino acid profile where possible, or for blends that combine sources such as pea with rice.
4. Always Read Customer Reviews
Real user feedback reveals taste, texture, mixability and potential tummy troubles. Sort by most recent to avoid outdated formulations. Scan a mix of 5-star and 1-star reviews to find consistent themes such as strong sweeteners, chalky texture or clumpy mixing.
5. Look for Nutritional Transparency
Trustworthy brands provide clear labels, batch numbers and quality testing information. Third-party certification is a strong plus, especially for athletes who are subject to testing. Look for programmes such as Informed Sport, which screens for substances banned in sport.
6. Do Not Be Swayed by Marketing Claims
Bold promises and flashy packaging can distract from poor formulas. Prioritise facts over hype. Compare nutrition panels side by side and check the grams of protein per 100 g and per serving rather than relying on broad claims like premium or ultra pure.
7. Know the Sugar and Sweetener Content
Added sugars can creep in via syrups and flavour blends. If you prefer to limit sugar, choose products with minimal added sugar and consider naturally sweetened options that use stevia or monk fruit. If you are sensitive to certain sugar alcohols, check for xylitol, sorbitol or erythritol on the label.
8. Check the Price per Serving
Do not be fooled by tub size. Work out the cost per serving to compare like for like. For example, if a 1 kg bag costs £24 and contains 33 servings, the price per serving is about 73p. Also consider the grams of protein per serving. A slightly higher price can be better value if it delivers more protein and better ingredients.
9. Test with Smaller Tubs or Sample Packs First
Before you commit to a 2.5 kg sack, try a small tub or a mixed sample box to test flavour, sweetness and mixability. This reduces waste and helps you find a flavour you actually enjoy. Subscriptions that offer flexible flavour swaps can also be a smart way to experiment.
10. Look for Return or Satisfaction Guarantees
Reputable retailers often provide a satisfaction or taste guarantee. If you are unsure about a flavour, check the returns policy so you know where you stand. This is especially helpful when ordering from a new brand.
