Our verdict on each
Gruns
Gruns is a US supplement brand that suits adults who want a single daily routine covering greens and vitamins minerals at a serving cost of $1.07. Third-party testing and certification to nsf and gmp back it up, and the money back window gives time to judge it.
WeightWorld
WeightWorld suits lifters who want a cheap creatine tub and a wider sports-nutrition order in one place, with prices from €24.99 and a serving cost of €0.28. It is a broad shop rather than a specialist, so check the subscription rate before you commit.

Pros and cons
Gruns
Pros
- Covers greens and vitamins minerals in one brand, so a daily routine does not need splitting across makers.
- Third-party testing is stated, and the products carry nsf and gmp certification.
- Subscription orders are reduced by 55%, which is the cheapest way to hold the daily price at $1.07 a serving.
Cons
- Gruns sells in US only, so buyers elsewhere cannot order from the brand directly.
- The subscription discount of 55% is tied to repeat orders, and the entry price of $29.99 is the figure at the top of the range.
- Product types cover greens and vitamins minerals, and a wider range sits at DocMorris, which lists multivitamins, vitamins minerals and omega 3.
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
Who each suits
Gruns
Who it suits
- US adults who want greens and vitamins covered by a single daily subscription rather than separate products.
- Vegan shoppers and anyone avoiding gluten, as the range is vegan and gluten free.
- Readers who care about independent testing and named certification, since the products are third-party tested and carry nsf and gmp.
Who should look elsewhere
- Buyers outside the US, since Gruns operates in the United States only.
- Shoppers who want a single specific product such as omega-3, probiotics, collagen or electrolytes, which sit with DocMorris at multivitamins, vitamins minerals and omega 3.
- People who would rather test a men's health brand such as ProSolution Plus or TestRX, where vitamins minerals and vitamins minerals are the only listed types.
WeightWorld
Who it suits
- Lifters buying creatine monohydrate on a tight per-serving budget
- People in Ireland, GB and FR who want one shop for creatine, pre-workout and electrolytes
- Vegetarians and vegans shopping vegan, vegetarian and keto products with gmp and vegan
Who should look elsewhere
- Buyers who want the widest sports-nutrition catalogue, since Body Attack carries whey protein, plant protein and creatine
- People who want electrolyte tablets from a single-purpose line, as Nuun carries electrolytes
- Shoppers who prefer a smaller creatine and pre-workout line, since CON-CR?T Creatine lists creatine, electrolytes and pre workout

Questions about each
Gruns
How much does Gruns cost at the point of buying?+
The entry price is $29.99 across the collection. That is the figure a reader meets first when ordering. Once a routine is running, the cost that matters is the serving price of $1.07. Keep the two apart, since they are different numbers for different stages of buying.
What does a Gruns subscription cost over time?+
Repeat orders carry a discount of 55%, and that is the route that holds the serving price down. A one-off order pays the entry price of $29.99 instead, so the ongoing figure only applies on a schedule. A 30 day money back window gives a first order time to be judged.
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.
