💡 The essentials
- Zumub is a Portuguese online shop (Zumub SA, near Lisbon) that sells more than 200 brands and its own whey range, made in the European Union.
- Its whey is one of the cheapest per kilo of protein: about $48 to $50 for the Whey Concentrate and $50 to $54 for the isolate, at the sale prices shown on 30 October 2026.
- The flip side: flavoured recipes with sucralose and acesulfame K, no stated milk origin and crossed-out prices that change often.
- Customers are fairly happy: 4.2 out of 5 on Trustpilot (8,158 reviews), with complaints about delivery and price rises.
- Our verdict: a very good price, but not the cleanest whey. For a sweetener-free isolate made from French milk, Nutripure Whey Isolate Native remains our first choice.
Zumub is the shop you see everywhere on Instagram and TikTok, with influencer codes in every other video and cut-price whey. But what is Zumub whey really worth once you read the label? We checked the prices, labels and customer reviews on the official site, and summarised the most-watched YouTube video on the subject.
🔬 Our method
This review is based on the official product pages of zumub.com (ingredients, nutrition facts, euro prices), its terms of sale and Trustpilot, all read on 30 October 2026. Zumub bills in euros: dollar prices are converted at the European Central Bank rate of 29 October 2026 (1 € = $1.113). We do not run lab tests and we do not taste the products: we compare labels and prices per kilo of protein, with the same grid as every brand on the site.
🏭 Who is behind Zumub?
Zumub is first of all a Portuguese online retailer, not a manufacturer. The company Zumub SA is based in Agualva-Cacém, in the Lisbon suburbs, according to its terms of sale. It claims more than 10,000 products from over 200 brands (Optimum Nutrition, BioTechUSA, Scitec…) and more than 4 million orders delivered.
Alongside those brands, Zumub sells its own range under the Zumub name, including three wheys. Its product pages say “Made in the EU”, without naming the factory or the milk origin. To see how the brand compares with others, read our ranking of the best whey protein brands.
🥛 Zumub wheys under the microscope
We looked at the three Zumub-brand wheys: the concentrate, the isolate and Clear Whey Hydro. The prices below are the sale prices shown in euros on 30 October 2026; the crossed-out prices are much higher, and the brand changes them often.
100% Whey Concentrate, the cheapest
| Criterion | 100% Whey Concentrate (chocolate) |
|---|---|
| Protein per 100 g | about 71 g (21.4 g per 30 g serving) |
| Unflavoured version | about 76 g per 100 g (22.7 g per serving), no sweetener |
| Ingredients | Whey concentrate 93%, fat-reduced cocoa, flavouring, xanthan gum, salt |
| Sweeteners | Acesulfame K and sucralose (except the unflavoured version) |
| Sale price | $19.58 (500 g), $35.60 (1 kg), $68.99 (2 kg), $136.89 (4 kg) |
| Price per kilo of protein | about $48 (4 kg) to $55 (500 g) |
It is a classic concentrate, with a fairly short ingredient list for a flavoured whey. Its big strength is the price: about $50 per kilo of protein in the 1 kg size at the sale price. At the crossed-out price of $52.30 per kilo, it rises to about $73 per kilo of protein, which changes everything: always check the day’s price before you order. It comes in fifteen flavours, which we ranked in our guide to the best Zumub whey flavour.
100% Whey Isolate, the richest in protein
Zumub’s isolate shows 24.7 g of protein per 30 g serving in chocolate, about 82 g per 100 g, with 0.6 g of fat. Answering a customer, the brand says its proteins are native and that the isolate is “almost free of lactose”: almost, not zero. It costs $44.51 per kilo on sale, about $54 per kilo of protein, and $165.81 for 4 kg (about $50). At the crossed-out price of $74.18 per kilo, that becomes about $90 per kilo of protein. For the difference between the two families, read whey isolate vs whey concentrate.
Clear Whey Hydro, the fruity drink
Clear Whey Hydro is a hydrolysed whey protein you drink like a juice: 25 g of protein per 30 g serving in wild fruits (about 83 g per 100 g), with citric acid, beetroot colouring, sucralose and acesulfame K. At $38.93 per kilo on sale, it is the cheapest Zumub whey per kilo of protein, around $47. It suits people who dislike milky shakes; to see whether hydrolysate is worth it, read our guide to hydrolysed whey protein.
🎥 What the reference YouTube video says
The most-watched French-language review of Zumub whey is a short from the Team NOCSY channel (about 800 views, May 2026), which gives it 2 out of 10. Note: the video ends on a discount code for a rival brand, Nutri&Co. Here are its points, checked against today’s label:
- “92.6% protein concentrate”: today’s label for the chocolate version shows 93% whey concentrate. That matches.
- “Packed with artificial sweeteners”: true for the flavoured versions (sucralose and acesulfame K). The unflavoured version has none, which the video does not mention.
- “No information on the milk origin”: still true. The product page only says “Made in the EU”.
- “Under €20 a kilo”: no longer the case. On 30 October 2026, a kilo cost $35.60 on sale and $52.30 at the crossed-out price.
- Aftertaste and lumps: a tasting impression we cannot check on a label.
Our take: the video is right about transparency and sweeteners, but it overstates the rest and its price is out of date. You can watch it on YouTube (Team NOCSY).
💬 What customers say
Zumub scores 4.2 out of 5 on Trustpilot, from 8,158 reviews (read on 30 October 2026). Positive reviews praise the prices and speed; negative ones mostly target pickup-point delivery. On the Whey Concentrate page, the rating is 4.5 out of 5 (3,873 reviews), but in July 2026 one customer called out an “outrageous price increase” compared with the year before.
Zumub offers a money-back guarantee on its own Zumub-brand products: return within 30 days, with at most a third of the product used, once per customer. That is rare in sports nutrition.
🏷️ Zumub discount codes: what really exists
The official site publishes its active coupons on a dedicated page. On 4 November 2026, no general code: LOSS-30 (30% off, Zumub Professional excluded) ended on 3 November, ZUMBIE and PACKS-15 on 1 November. PRO-10 (10% cashback on Zumub Professional) and a €5 ($5.57) voucher on your first order with the newsletter remain. But coupons do not apply to products already on sale, which was the case for the Zumub wheys that day. Everything is detailed on our Zumub discount code page.
⭐ Our rating of Zumub

| Short recipe, few additives | ★★★☆☆ |
| Transparency (milk origin, factory) | ★★☆☆☆ |
| Price stability | ★★☆☆☆ |
| Customer reviews | ★★★★☆ |
⚖️ Zumub or Nutripure?
| Criterion | Zumub 100% Whey Isolate (chocolate) | Nutripure Whey Isolate Native (unflavoured) |
|---|---|---|
| Protein per 100 g | about 82 g | 86.8 g |
| Additives | Flavourings, thickener, salt (by flavour) | Sunflower lecithin only |
| Sweetener | Sucralose, acesulfame K (except unflavoured) | None |
| Lactose | “Almost free” | Under 0.2% |
| Milk origin | Not stated (made in the EU) | France |
| Price on 30/10/2026 | $44.51 (1 kg) to $165.81 (4 kg), on sale | $49.97 (750 g) to $211.36 (4 kg) |
| Price per kilo of protein | about $50 to $54 | about $61 to $77 |
On price, Zumub clearly wins: about $11 less per kilo of protein than Nutripure in large sizes, as long as its sale prices hold. On purity and transparency, Nutripure comes first: more protein per 100 g, no sweetener, a single lecithin as additive and French milk, where Zumub does not say where its milk comes from. Note that Nutripure is a French shop. If budget comes first, Zumub is a good buy; if you want the cleanest possible isolate, read our ranking of the best whey isolate.
✅ Who is it for? ❌ Who is it not for?
- For you if price per kilo of protein is your number one criterion, and you buy during a sale.
- For you if you like dessert flavours (rice pudding, apple pie, cookies) or a clear, juice-like whey.
- Not for you if you want to avoid sucralose: then take the unflavoured version, or a plain whey.
- Not for you if you want to know where the milk comes from: pick one of the wheys in our guide to the best French whey protein.
🏁 Our verdict on Zumub
Zumub sells an honest whey at a very low price when it is on sale, with a wide choice of flavours and a real money-back guarantee. Its weak points are the sweeteners in the flavoured versions, the vagueness about milk origin and crossed-out prices that move a lot. If you are after purity and French milk above all, Nutripure Whey Isolate Native remains our first choice.
⚠️ Warning
Whey supplements your diet, it does not replace a meal. If you have a milk protein allergy, are pregnant or have kidney disease, ask your doctor before taking it. For the right dose, read how much whey protein per day.
