What Is C Nutrition?
C Nutrition is a European sports-nutrition retailer built around IO GENIX, its own in-house supplement brand, positioning itself as "the reference for your dietary supplements." The catalog covers the categories a gym-focused shopper typically wants in one place: whey and isolate protein, pre-workout formulas, amino acids, recovery products, plus a smaller line of food items (like oat flour) and general wellness support supplements such as collagen. The site operates across multiple European countries, with language and currency adjusting by region, and runs an ambassador program for brand-affiliated athletes and influencers.
How We Picked This
We picked C Nutrition by checking its published catalog and pricing directly on the site rather than relying on marketing copy alone, and we specifically looked for a store-wide review badge (Trustpilot, Judge.me, or similar) — none was visible on the pages we checked, which we disclose below rather than assuming it exists. This is disclosed research based on the merchant's own published information, not an in-house trial, and it is not medical or dietary guidance — see how we test products for the full policy.
What C Nutrition Sells
The catalog is built around IO GENIX, the site's house brand, across three practical groupings.
Protein & Recovery
The core of the catalog: IO GENIX Whey 80 Professional (2kg, €83.95) and IO GENIX Isolate Professional (2kg, €109.95) anchor the protein line, alongside recovery-focused formulas aimed at post-workout use.
Pre-Workout & Amino Acids
A performance-focused line of pre-workout blends and amino acid supplements, priced in a similar mid-range bracket to the protein products, marketed toward gym-goers training regularly rather than casual users.
Food & General Wellness
A smaller line rounds out the catalog — IO GENIX Delicious Oatmeal (oat flour) runs €4.90–€6.95 depending on size, and general wellness items like collagen sit alongside the performance-focused core range.
Real Customer Feedback
We did not find a store-wide review rating or badge (Trustpilot, Judge.me, or a similar third-party widget) displayed on the pages of c-nutrition.com we checked. That's different from a confirmed bad rating — it means we simply could not locate independently aggregated customer feedback to cite here. In the absence of verified third-party review data, treat this as an unrated merchant for review-aggregation purposes, separate from the real, checkable pricing and shipping terms below.
Pricing, Shipping & Coupons
Pricing is confirmed directly from the site and spans a low-cost oat-flour item to the 2kg protein tubs; verify current pricing before ordering since supplement retailers frequently run time-limited promotions.
| What | Price | Notes |
|---|---|---|
| IO GENIX Delicious Oatmeal | €4.90–€6.95 | Oat flour, priced by size |
| IO GENIX Whey 80 Professional (2kg) | €83.95 | Core whey protein line |
| IO GENIX Isolate Professional (2kg) | €109.95 | Premium isolate protein — flagship item |
Free shipping applies on orders over €69, and a 14-day return guarantee is advertised on-site ("Garantie 14 jours" / 14 days to return your order). A coupon code — NONG10 — is available through RankerNest's affiliate link above; we have not tested a live order to confirm the exact discount amount it applies.
C Nutrition Pros & Cons
Pros
- Focused catalog under one house brand (IO GENIX) rather than a sprawling multi-brand marketplace
- Confirmed free shipping threshold (€69) and a stated 14-day return guarantee
- Pricing spans an accessible €4.90 entry point to premium 2kg protein tubs
- A working coupon code is available through our link
Cons
- No store-wide review badge (Trustpilot, Judge.me, etc.) found on the site
- We have not personally used any IO GENIX product to confirm taste, mixability, or effect
- This page is informational only — not medical, dietary, or professional advice
- Multi-country site means pricing/availability may vary by the region you're shopping from
Who Should Shop C Nutrition?
Athletes and regular gym-goers who want protein, pre-workout, or recovery supplements from a focused, single-brand catalog rather than comparing dozens of competing brands on a general marketplace, and who are comfortable ordering from a merchant without an independently aggregated review score to check first.
C Nutrition is NOT right for you if: you specifically want to verify a store's reputation through an independent review platform before ordering, or you're looking for medical or dietary guidance rather than a product catalog — this page and this store are not a substitute for professional advice.
Other Health & Wellness Picks
If C Nutrition isn't quite what you're shopping for, here's what else we currently feature in the same category:
- 7DaysNatural — natural skin and hair care, use code NONGVANHOANG
- Bowflex SelectTech 840 Kettlebell — an independently-reviewed adjustable kettlebell with a verified 4.8/5 Amazon rating
Final Verdict: Is C Nutrition Worth It?
C Nutrition's catalog is focused and the pricing we confirmed directly from the site is competitive for a house-brand supplement range, with a real free-shipping threshold and a stated 14-day return window as genuine backstops. What we can't offer is an independent reputation check — we found no store-wide review badge, and we haven't personally used a product to speak to taste or effect. If you're comfortable evaluating a supplement brand on its own published terms rather than aggregated third-party reviews, the working coupon code is a real, checkable perk.
