Our verdict
Scored on the label and the price, not on how it tastes.
- 90g of protein per 100g on the label, matching the highest whey isolates
- Completely dairy free and lactose free
- Zero fat and zero sugar on the label
- Around 32 fruit and soft-drink flavours, which work better than dessert flavours in water
- No published amino acid profile, which is the only thing that would settle whether this is muscle protein or collagen
- Beef protein powders as a category are widely criticised for being collagen-based; collagen scores 0.00 on PDCAAS against whey’s 1.00
- No third-party testing certification found
- Neither the country of manufacture nor the source of the raw protein is disclosed by NXT
Read the full verdict
For anyone who cannot take dairy, this is a genuine option at 90g of protein per 100g with zero fat and zero sugar on the label. The category carries one well-documented criticism you should understand before buying: many beef protein powders are made from hydrolysed collagen or gelatin rather than muscle protein, and collagen scores 0.00 on the PDCAAS protein quality scale against 1.00 for whey. The way to settle that for a specific product is its amino acid profile, and NXT does not publish one. We are not saying this product is collagen. We are saying nobody outside NXT can currently tell.
Where to buy NXT Nutrition Beef Protein Isolate
Ordered by cost per 25g of protein, because pack sizes and protein densities differ enough that a headline price on its own does not tell you which is better value.

Ingredients and formulation
- 01Beef protein
Dairy free and lactose free, which is the main reason people buy it. NXT does not state whether the beef protein is muscle-derived or hydrolysed collagen, and publishes no amino acid profile.
Steviol glycosides, Sucralose
540g · 1.8kg · 20-sachet mixed pack
Around 32 flavours, almost all fruit and soft-drink styles rather than dessert flavours, which suits a dairy-free product mixed with water.
Third-party testing
Certification is per programme and often per flavour or per batch, so a badge on one product does not carry across a brand’s whole range.
Does not appear in any public third-party testing database.
Made by
NXT Nutrition, a registered trademark of Muscle Finesse Ltd, UKRetailers state it is made in the UK; NXT itself does not say so, and does not disclose the source of the raw beef protein.
What the maker does not publish
- NXT publishes no amino acid profile. Until it does, the collagen question cannot be settled for this product either way.
- NXT markets the product as rich in leucine and glutamine, but that is a marketing claim with no published data behind it.
- Neither the country of manufacture nor the origin of the beef protein is disclosed.
- Much of the critical writing about beef protein as a category is published by companies that sell whey, so read it with that in mind.

Frequently asked questions
How much protein is in NXT Beef Protein Isolate?
27g in a 30g scoop, 90g per 100g on the label. That matches the highest whey isolates on the UK market.
Is beef protein isolate as good as whey?
It depends entirely on whether it is made from muscle protein or from collagen, and that varies by product. Collagen is very low in the essential amino acids that drive muscle protein synthesis and scores 0.00 on the PDCAAS scale, where whey scores 1.00. The amino acid profile is what tells you which you have, and NXT does not publish one for this product.
Is NXT Beef Protein Isolate dairy free?
Yes. It contains no milk protein and no lactose, which is the main reason people choose it over whey.
