Three products that do different jobs
Creatine, pre-workout and electrolytes get grouped together because they all turn up in the same training bag, but they answer different questions. Creatine is a single-ingredient strength staple, pre-workout blends pair stimulants with supporting compounds, and electrolytes replace fluid and minerals lost through sweat. Buying the wrong one is the most expensive mistake in this category, so settle the job before you compare a single price.
Brand ranges tell you how much of that decision has already been made for you. Body Attack lists creatine, pre-workout and electrolytes among whey protein, plant protein and creatine, so one brand can cover all three needs. Nuun sits at the opposite end, with electrolytes as its only category, which makes it a focused hydration choice rather than a one-stop shop. WeightWorld runs a much wider catalogue spanning multivitamins, vitamins minerals and omega 3, so hydration sits alongside many other formats.
Start by narrowing the field in our ranking of Creatine, pre-workout and electrolytes, then read the individual Body Attack and Nuun write-ups to see how each range is actually built.
Anchor the budget to the range, then check the serving cost
Prices in this category spread wide, and a headline price rarely tells you what regular use costs. Across the tracked listings, entry prices run €2.54 to €91.41 and cost per serving runs €0.28 to €8.76. Treat those two figures as the outer boundary of your budget before you look at any individual brand, because the gap between the cheapest and dearest option is large enough to change your choice on its own.
Worked examples. Nuun's electrolyte range prices run $7.49, which works out at $0.75 per serving, and a subscription order saves 15% on repeat deliveries. Body Attack's published figures come from its whey protein line, with prices run €29.99 and €1 per serving, so expect the creatine and pre-workout products to price differently. WeightWorld's catalogue is broader still, starting at prices run £5.12 and £0.09 per serving.
Do the arithmetic in a single currency before you draw a conclusion. Nuun quotes in US dollars, while Body Attack prices in euros and WeightWorld in pounds, so a dollar figure and a pound figure tell you nothing about which brand is cheaper until you convert. A subscription saving is worth real attention here, because the commitment period is where the effective per serving cost quietly drops.
Where the brand sits and where it ships
Reach matters as much as price for anything you plan to reorder. WeightWorld ships to a long country list covering AL, AO and AR, and it trades as Comfort Click Ltd from the GB. Body Attack is run by Body Attack Sports Nutrition GmbH & Co. KG out of the DE and ships across Europe and beyond to DE, AT and BE.
Nuun is the narrowest of the group, with US and CA making up its whole market list, and the company behind it is Nuun & Company, Inc., headquartered in the US. A tight footprint can be a fair trade for a focused product line, but it is a hard limit if you sit outside those markets, and it is worth checking before you plan a subscription.
Certification and third-party testing
The cheapest reliability check available to you is the certification line, because it names the body that inspected the product. The three broad ranges here are all third-party tested, including WeightWorld, Nuun and Body Attack, but their published credentials differ: WeightWorld lists gmp and organic, Nuun lists informed sport and vegan, and Body Attack lists organic and vegan.
For a specialist, CON-CR?T Creatine has the plainest certification story of the four, with nsf and gmp among its credentials. An NSF listing is a US scheme worth recognising if you order across the Atlantic, while GMP speaks to how the product is manufactured rather than to a test of the finished tub, so both lines are useful but they answer different questions.
Diet fit is the second half of this check, and it decides repeat orders more often than taste does. WeightWorld lists vegan, keto and gluten free, Nuun lists vegan, gluten free and kosher, Body Attack lists vegan, vegetarian and gluten free, and CON-CR?T Creatine lists vegan, gluten free and kosher. Read this line before you read the front of the tub.
The guarantee window as a trial period
A returns window is the most useful reliability signal a supplement brand can offer, and it costs nothing to check. WeightWorld offers 90 days, the longer of the published windows here, and has traded since 2006. Nuun offers 60 days.
Use the window rather than ignoring it. Order a full tub, use it for the length of the guarantee, and if the taste, mixability or results disappoint you have a defined route out instead of a decision made on day one. The CON-CR?T Creatine write-up is a useful companion read for the certification side of the same question.
Serving size, protein content and flavour
A serving cost only means something once you know what a serving contains. Electrolyte tablets are small by design, so the 0 g of protein per serving at Nuun is not a weakness, it is confirmation that the product does a single job. A protein powder is the mirror image: Body Attack's listed line carries 24 g per serving, set against a tracked spread of 0 to 34 g across the listings. Match the product to the number you actually need.
Flavour is a retention factor rather than a performance one, and it decides whether you reorder. Nuun offers 10 flavours in its electrolyte range, while Body Attack's listed line offers 18 flavours. If the option you pick turns out to be one you avoid, the guarantee window is your exit.
Put the checks in order
A workable sequence: decide which of the three products you need, set a ceiling from €0.28 to €8.76 per serving, confirm the brand ships to your market, read the certification and diet lines, then read the guarantee window before you check out. Support is the final tiebreaker, and it varies: Nuun offers email, phone and help centre, Body Attack offers email, phone and help centre, and WeightWorld offers email, phone and help centre.
