Start with the protein number, not the label
The figure that separates a protein powder from its rivals is how much protein a serving actually carries. Across the range listed here, serving sizes run 15 to 40 grams. That spread matters because a scoop with a lower protein figure usually costs more per gram of protein than one at the higher end.
Body Attack lists 24 grams per serving on its whey product. HUM Nutrition lists 20 grams on its core-strength powder, Myvitamins lists 18 grams on its clear whey blend, and Protein Works has no serving figure listed. A brand with no figure cannot be compared on this point, so check the nutrition panel rather than assuming it matches the others.
Read the serving size as well as the protein. Powders with a similar protein number can use very different scoops, and the cheaper powder per tub is often the one with the larger serving. Divide the protein figure by the serving weight to get a fair protein density, then compare that across the shortlist.
Turn price into a cost per serving
A tub price on its own tells you little, because tub sizes differ widely. Across the range, entry prices run €3.67 to €91.41. What matters more is the cost of a single serving, which runs €0.93 to €8.76.
Body Attack sells its whey at €29.99 and works out at €1 a serving. Myvitamins lists an entry price of £5.10 on a gummy multivitamin, though that is a different product category, and its serving price of £0.09 belongs to that item rather than to a protein powder. Use the protein entries only.
HUM Nutrition has no serving price listed, but it does offer a subscription discount of 30% off, which changes the maths on repeat purchases. Work out your own monthly serving count, multiply by the serving price, and only then decide whether a subscription is worth taking. If a brand does not publish a serving price, treat the tub price as the only anchor available and be more cautious about how far you trust the comparison.
Check the diet label matches your own
Diet tags decide whether a powder is usable at all. Body Attack covers vegan, vegetarian and gluten free, Myvitamins lists vegan, and Protein Works covers vegan, vegetarian and gluten free. HUM Nutrition has no diet range listed for its protein powder, so anyone avoiding a specific ingredient has fewer questions they can answer up front.
Allergen wording, cross-contamination statements and the certification marks behind a diet claim sit in a different place. Body Attack lists organic and vegan among its certifications, while HUM Nutrition lists gmp. A diet tag tells you what the maker claims; a certification is the paperwork behind it.
The Myvitamins review and the Protein Works review are useful next steps for anyone narrowing by ingredients, because the shortlist here is only as good as what each brand actually states.
Use flavours as a repeat-purchase signal
Flavour count is a plain proxy for how often a brand can keep you from getting bored. Body Attack offers 18 flavours on its whey line and Protein Works offers 8 flavours on its whey protein range. HUM Nutrition and Myvitamins have no flavour count listed.
A wider range means more chance your preference is covered, but it also tells you nothing about taste. Judge flavours after the numbers line up: decide whether the protein per serving and the serving price sit in the right range first, then pick a flavour from what is left.
The Body Attack review is worth a look if flavour variety is the tiebreaker, since a higher count only helps if the options are ones you would drink.
Confirm the brand can actually ship to you
Availability quietly removes options. Body Attack ships to DE, AT and BE, so it works for most European buyers as well as further afield. HUM Nutrition lists US, Myvitamins lists GB, and Protein Works has no market list on record.
Cross-border shoppers should also note where a company sits. Body Attack is based in DE as Body Attack Sports Nutrition GmbH & Co. KG, Myvitamins is based in GB as THG Nutrition Limited, and Protein Works is based in GB as Class Delta Limited. HUM Nutrition is based in US as HUM Nutrition, Inc.
Where a brand sells in a single market, your comparison is effectively finished early. Check the market list before you spend time on serving maths.
Treat third-party testing and support as the final check
Independent batch testing separates brands that publish it from those that do not mention it. Body Attack is third-party tested and HUM Nutrition is third-party tested, while the remaining brands do not state testing either way. Where a brand says nothing, you are trusting its own quality process rather than an outside check.
Support is the other part of reliability. Body Attack, HUM Nutrition, Myvitamins and Protein Works all offer email, phone and help centre, so you can reach a person by more than one route whichever you pick. That matters most when a delivery goes wrong or you need a replacement.
For a broader field, the Protein powders rankings sort brands on the same measures, and the HUM Nutrition review takes a closer look at testing and quality.
A short order of operations
Work through the checks in one pass rather than jumping between them. Confirm the brand ships to you, rule out any powder whose diet tags clash with your needs, compare protein per serving next to the serving price, then use flavour count and money-back terms to break a tie.
Some of these brands publish a money-back window. HUM Nutrition offers 30 days and Myvitamins offers 30 days, while Body Attack and Protein Works have no window on record. A stated window gives you room to try a new powder without long-term commitment.
Brand histories help with a final sanity check. HUM Nutrition was founded in 2012, Myvitamins in 2012, and Protein Works in 2013, while Body Attack has no founding year on record.
Once those steps are done, the shortlist is usually small, and the brand reviews gathered in the Protein powders rankings will settle it.
