💡 The essentials
Eric Favre whey is a decent French brand that you will find in plenty of shops, but its flagship whey (Iso Zero) is not a pure isolate: it is a blend of isolate and concentrate, with two sweeteners (sucralose and acesulfame K). It suits you if you want lots of flavours. It does not suit you if you are after the shortest ingredient list at the best price.
- Protein: 85 g per 100 g in the vanilla Iso Zero (25.5 g per 30 g serving).
- Price: around €57 per kilo in the 1.5 kg tub (checked in October 2026).
- Customer reviews: 4.4/5 on Avis Vérifiés (7,320 reviews since 2018).
- Promo codes: PROMO10, PROMO15 and PROMO30 shown on the site until 6 October 2026.
You have spotted Eric Favre whey in a French pharmacy or on Amazon and you are wondering whether it is worth the money? We went through the brand’s entire whey range, product page by product page: ingredients, price per kilo and customer reviews.
Spoiler: Eric Favre is neither a scam nor a premium whey, it is a mass-market brand with a lot of choice. It is a French brand, and its online shop ships from France.
🔬 Our method
We compared the official product pages of every whey sold on ericfavre.com on 3 October 2026: ingredient list, protein per 100 g as sold, sweeteners, stated milk origin, price and price per kilo. We added the ratings published on Avis Vérifiés and on the brand’s own site, the official French company register and the promo code page. No lab testing and no tasting were carried out.
🏭 Who is behind the Eric Favre brand?
Eric Favre describes itself as “a brand of Les Trois Chênes laboratories”, a laboratory based in the Rhône department of France. According to the official company register, Les Trois Chênes is an SAS (a French simplified joint-stock company) based in Villechenève (69), founded in 2004 and now chaired by Jean-Noël Negroni. The ericfavre.com shop itself is run by OMNIBIZ SAS, in Puteaux, according to the site’s legal notice.
The brand highlights a French laboratory certified to ISO 22000 and ISO 9001 and states that every batch goes through third-party testing (banned substances, heavy metals), which we could not verify ourselves.
On price, Eric Favre sits in the mid-range: €43 to €57 per kilo for its whey in large tubs, with regular promo codes on its site (the discounts page listed around ten of them in October 2026).
🥛 Which whey proteins does Eric Favre sell?
The range includes four “pure” whey proteins (Iso Zero, Whey Zero, Muscle Whey Protein, Clear Shake) and three multi-source blends that add other proteins.
Iso Zero 100% Whey Protéine: the flagship whey isolate
Despite its name, Iso Zero is a blend: 64.8% whey isolate and 31.9% whey concentrate in the vanilla version. It delivers 25.5 g of protein per 30 g serving, which is 85 g per 100 g (82.4% in the chocolate coconut flavour). The product page describes the whey as “made from French milk”.
The full list (vanilla): whey isolate and concentrate, flavouring, carboxymethylcellulose, sunflower lecithin, guar and xanthan gums, salt, sucralose and acesulfame K. Even the “Naturel” (unflavoured) version contains sucralose and acesulfame K, according to its ingredient list.
It comes in 11 flavours and three sizes: €35.90 for 500 g, €84.90 for 1.5 kg (€56.60 per kilo) and €104.90 for 2 kg (€52.45 per kilo), checked in October 2026. Its product page shows a rating of around 4.5/5 from nearly 1,800 reviews.
Whey Zero: the whey concentrate
This is a whey concentrate with 22.5 g of protein per 30 g serving, which is 75 g per 100 g. The chocolate recipe adds flavourings, cocoa, carboxymethylcellulose, lecithin, gums, salt, sucralose, acesulfame K and a colouring (brown HT). Expect to pay €86.90 for the 2 kg tub, or €43.45 per kilo (October 2026), for a 4.6/5 rating from 56 reviews.
Muscle Whey Protein: the concentrate with stevia
Another concentrate: 22.2 g of protein per 30 g serving (74 g per 100 g), sweetened with sucralose and stevia, with no acesulfame K. It comes in vanilla, chocolate and cookie. It was on offer at €67.91 for 1.5 kg instead of €79.90 (€45.27 per kilo on promotion), with only 4 published reviews.
Clear Shake: the clear whey isolate
This is the purest whey in the range: 93% whey isolate (Volactive), 87 g of protein per 100 g, with citric acid, flavouring, beta-carotene and sucralose. The downside: €42.90 for 450 g, or €95.33 per kilo, which makes it the most expensive per kilo of protein. Rating: 4.6/5 from 200 reviews.
Optimax, Iso Fusion, Iso Whey Zero Advanced: the blends
These three products are not pure whey, even though “whey” appears in their names. Whey Optimax (74.7 g of protein per 100 g, €64.90 for 1.5 kg) blends whey concentrate, yeast protein and milk protein, with erythritol, sucralose and stevia. Iso Fusion and Iso Whey Zero Advanced add egg (and pea, in Iso Fusion) to the whey.
| Eric Favre whey | Type | Protein / 100 g | Sweeteners | Price per kilo (Oct. 2026) |
|---|---|---|---|---|
| Iso Zero | Isolate + concentrate | 82 to 85 g | Sucralose, acesulfame K | €56.60 (1.5 kg) |
| Whey Zero | Concentrate | 75 g | Sucralose, acesulfame K | €43.45 (2 kg) |
| Muscle Whey Protein | Concentrate | 74 g | Sucralose, stevia | €45.27 on promotion |

| Whey Optimax | Blend | 74.7 g | Erythritol, sucralose, stevia | €43.27 (1.5 kg) |

⭐ Eric Favre reviews: what customers say
On Avis Vérifiés, ericfavre.com scores 4.4/5 from 7,320 reviews since February 2018, with 1,165 reviews over the last twelve months: 75% five stars, 16% four stars and 3% one star (checked on 3 October 2026). We did not find an active Trustpilot page for the brand.
According to the summary published by Avis Vérifiés, customers mainly mention how easy it is to order, the taste, the texture and how well the protein digests. Among the less positive recent reviews, there are comments on the site’s navigation, on the taste or texture of a product, and on the shipping costs for home delivery.
🏷️ Eric Favre promo codes: the current offers
The public codes shown on the official discounts page on 3 October 2026 are the French Days ones: PROMO10 (€10 off from €60), PROMO15 (€15 off from €80) and PROMO30 (€30 off from €130), valid until 6 October 2026 in mainland France, excluding products already on promotion, and they cannot be combined.
A concrete example: with PROMO15, the 1.5 kg tub of Iso Zero drops from €84.90 to €69.90, which is €46.60 per kilo. The same page also lists SHAKERFREE (a free shaker from €50 spent in the protein or gainer sections, until 31 December 2026) and a free “Prise de masse” (mass gain) ebook with the brand’s whey.
For delivery, the delivery page states €5.90 to a pick-up point, free from €60, and free home delivery from €100. The promo code page, however, mentions free delivery from €80: check the amount in your basket. Be wary of codes found on third-party sites, which we could not verify.
⚖️ Eric Favre or Nutripure?
Label against label, Nutripure’s Whey Isolate Native (unflavoured version) is purer and cheaper per kilo of protein than Iso Zero. Here is the point-by-point comparison, based on the official product pages.
| Criterion | Eric Favre Iso Zero (vanilla) | Nutripure Whey Isolate Native (unflavoured) |
|---|---|---|
| Protein / 100 g as sold | 85 g | 86.8 g |
| Type of whey | Isolate + concentrate | Native isolate |
| Additives | Carboxymethylcellulose, lecithin, guar and xanthan gums, flavouring, salt | Sunflower lecithin only |
| Sweeteners | Sucralose, acesulfame K | None |
| Lactose | Not stated on the product page | Less than 0.2% |
| Milk origin | French milk (according to the product page) | French milk |
| Price per kilo (Oct. 2026) | €56.60 (1.5 kg) | Around €47 |
| Cost of 100 g of protein | €6.66 | About €5.41 |
Where Eric Favre wins: the choice of flavours (11 for Iso Zero), availability in shops and pharmacies, and frequent promotions. With PROMO15, Iso Zero even drops to €5.48 per 100 g of protein, almost level with Nutripure, but only until 6 October.
Where Nutripure wins: a recipe with no sweetener, a native isolate with no concentrate, a stated lactose content below 0.2%, and a lower price per kilo outside promotions. Both brands ship from France. If you want to understand what “native” changes, read our comparison of native whey vs whey isolate.

ℹ️ Good to know
Sucralose and acesulfame K are sweeteners authorised in Europe: their presence is not a danger, it is a matter of preference. If you are pregnant, breastfeeding or being treated for kidney disease, ask your doctor before taking whey.
🏆 Our verdict on Eric Favre whey
In our view, Eric Favre whey is a reasonable buy if you want an indulgent, easy-to-find whey and you take advantage of a promotion. Iso Zero is the brand’s best whey for most people: 85 g of protein per 100 g and 11 flavours. If you prefer a pure isolate and price is no obstacle, Clear Shake has the cleanest label in the range.
Eric Favre is not for you if you avoid artificial sweeteners, if you want a 100% isolate or native whey, or if you buy outside promotions: at full price, Iso Zero costs more per kilo of protein than purer isolates. Also take care not to mistake the blends (Optimax, Iso Fusion, Advanced) for a pure whey.

Our pick for a pure whey isolate at the best price per kilo of protein is Nutripure’s Whey Isolate Native:
