Our verdict on each
Protein Works
Protein Works suits shoppers who want a wide range of daily supplement categories at a low entry price, with £8.99 to start. Buyers who put independent lab testing at the top of their list should look further, since third-party testing is not offered.
WeightWorld

Pros and cons
Protein Works
Pros
- Covers a wide list of categories in multivitamins, vitamins minerals and omega 3, from multivitamins to electrolytes.
- Entry point of £8.99 with a per serving cost of £0.15, ranked 15 of 121 brands on price per serving.
- The range suits different diets, with vegan, vegetarian and gluten free options on the multivitamin formula.
Cons
- Delivery covers GB, IE and FR, which is a narrower set of markets than some pharmacy-led rivals.
- The range carries 8 flavours on its whey protein line, but the entry pricing and per serving cost come from the multivitamin product.
- The £8.99 entry price ranks 23 of 157 brands, so the price on the front of the pack sits mid-table.
WeightWorld
Pros
- Serving cost of €0.28 puts WeightWorld at 1 of 46 brands compared on price per serving
- Entry price of €24.99 keeps the first order modest while the subscription rate of 10% trims repeat buys
- Range covers creatine, pre workout and electrolytes, wider than Nuun at electrolytes and CON-CR?T Creatine at creatine, electrolytes and pre workout
Cons
- Entry price of €24.99 places WeightWorld at 22 of 66 brands compared, well away from its per-serving value
- Creatine monohydrate comes in 1 flavour, so there is little choice for anyone who wants a flavoured powder
- Sells in Ireland, GB and FR, and that catalogue is narrower than Body Attack at whey protein, plant protein and creatine

Questions about each
Protein Works
How much does Protein Works cost to start?+
The entry price is £8.99 for the multivitamin product. The same product works out at £0.15 per serving, so a larger pack lowers the cost per serving. The per serving figure ranks 15 of 121 brands in this category.
Is there a discount for ordering repeatedly?+
Yes, subscriptions carry a 15% discount against the entry price of £8.99. The discount applies to repeat orders rather than the first purchase, so it only shows on the ongoing cost. Orders placed on a subscription continue until you change them.
WeightWorld
How much does WeightWorld creatine cost per serving?+
Creatine monohydrate is priced at €24.99 to start, and each serving works out at €0.28. That per-serving figure is what puts the brand at position 1 of 46 brands compared in the creatine and pre-workout group, so the serving cost matters more here than the tub size.
Is the first order the cheapest price?+
Not really. On price from, WeightWorld ranks 22 of 66 brands compared, so the entry figure is ordinary for the group. The value sits in the running cost of €0.28 a serving rather than in the opening price, so weigh the two before ordering.
