The short answer
Nutriforce is the most expensive in our price checks on comparable products: its magnesium costs 3.2 times Nat&Form’s, its zinc nearly seven times Nutrimea’s, and its collagen works out at more than 1,100 EUR per kilo. Above all, its pages carry health claims that European regulation does not authorise, such as « speeds up weight loss » for collagen and chromium. Several pages contradict each other on the dose or how long a box lasts. As for customers: 4.1 out of 5, and a reply to about 12% of negative reviews.
What our price checks measured
| Product | Nutriforce | Best benchmark | Gap |
|---|---|---|---|
| Magnesium bisglycinate | 0.480 EUR per 100 mg | 0.150 EUR, Nat&Form | 3.2 times more |
| Zinc | 0.80 EUR per day | 0.12 EUR, Nutrimea | 6.8 times more |
| Chromium | 0.40 EUR per day for 100 µg | 0.15 EUR for 250 µg, Nutrimea | 2.7 times more, for less chromium |
| Marine collagen | 1,133 EUR per kilo | 79.80 EUR, Dynveo | 14 times more |
Claims that the law does not authorise
In the European Union, a supplement can only claim a health effect if the claim appears in the register of authorised claims, under Regulation (EC) No 1924/2006. On Nutriforce’s pages we found:
- « Speeds up weight loss », for marine collagen and for chromium picolinate;
- « Regulates blood sugar » and « Improves sleep », for magnesium, when the authorised claims for magnesium relate to tiredness, the nervous system, muscles and bones;
- cortisol levels that « drop close to 0 » within a few days, for ashwagandha, a statement that no study supports and that would in fact be dangerous if it were true.
None of these wordings appears in the European register. For ashwagandha, Anses (the French food safety agency) advises against the plant for several groups of people: our comparison sets out its opinion.
Pages that contradict each other
The collagen is dosed at 1,000 mg per day, while the FAQ on the same page recommends « 5 to 10 g per day ». At the FAQ dose, a one-month box would last three to six days. The chromium is sold as a « 2-month course », then the page says that « a box can therefore last 30 days ». The ashwagandha is described as « ashwagandha root 500 mg », then as an extract standardised to 3% withanolides, less concentrated than the 5% KSM-66 used in studies. These inconsistencies make it impossible to know exactly what you are buying.

Our verdict
On the products we were able to compare, the same active ingredients can be found 2.7 to 14 times cheaper elsewhere, with pages that stick to authorised claims. We do not see any Nutriforce product to recommend against the benchmarks in our comparisons. If you place an order, check that no subscription is ticked when you pay.
How we put this review together
We have not tested these products and we do not claim to have. This review draws on two verifiable sources: our price and composition checks on the brand’s official website, converted to the price of the active ingredient and compared with the benchmarks in our comparisons; and aggregated customer reviews, checked on Trustpilot on 24/09/2026. A customer review measures the buying experience, not how effective a supplement is.
