USN Blue Lab Whey Review — Is It Worth It?

USN Blue Lab Whey positions itself as a premium whey protein to rival Optimum Nutrition Gold Standard. It delivers good protein content and solid taste, but struggles to justify its price point in a crowded UK market.

What Is It?

Blue Lab 100% Whey is USN's flagship protein powder, featuring a blend of whey isolate and whey concentrate. USN is a South African brand with a significant UK presence, stocked in Holland & Barrett and most supplement retailers. They position Blue Lab as their cleanest, highest-quality whey offering.

Ingredients & Nutrition

Per 30g serving, you get 24g of protein, 1.5g of fat, and 1.8g of carbohydrates at 118 calories. That's an 80% protein content, which is solid. The blend uses whey isolate and whey concentrate, though USN don't specify the ratio. Given the fat and carb content, it's likely concentrate-dominant.

The formula includes DigeZyme — a blend of digestive enzymes (amylase, protease, lipase, lactase, cellulase) — which mirrors the approach ON takes with aminogen. This genuinely helps with digestion and reduces bloating. Sweetened with sucralose. Contains milk and soy allergens.

Taste & Mixability

We tested Chocolate and Wheytella (their hazelnut chocolate flavour). Wheytella is the standout — it tastes remarkably like Nutella and is one of the more interesting protein flavours we've tried. Chocolate is decent but unremarkable. Overall, USN has fewer flavour options than MyProtein or ON.

Mixability is good. The powder dissolves well in a shaker with minimal lumps, and the texture is smooth. Not quite ON Gold Standard level, but above average.

Effectiveness

The 24g protein per serving with added digestive enzymes makes this an effective protein supplement for recovery and muscle building. The BCAAs content is around 5.3g per serving with 2.3g of leucine — solid numbers. The DigeZyme blend is a genuine benefit for anyone who experiences digestive discomfort with whey.

Value for Money

At £32.99 for 908g (roughly 30 servings), you're paying about £1.10 per serving. That's more expensive than ON Gold Standard (£0.97) and significantly more than MyProtein (£0.50). For a concentrate-dominant blend without Informed Sport certification, this is hard to justify. ON offers better credentials at a lower price, and MyProtein offers comparable nutrition at less than half the cost.

Verdict

USN Blue Lab Whey is a perfectly decent protein powder — the taste is good, digestive enzymes are a nice touch, and the protein content is solid. But at £1.10 per serving, it's asking for premium prices without delivering premium credentials. ON Gold Standard does the same job better for less money, and MyProtein undercuts it dramatically. If Wheytella flavour is calling your name, go for it. Otherwise, there are smarter choices.
