How the numbers stack up against the price
Three ingredients, 80g of protein per 100g, and 0.1g of salt, which is a thirtieth of what their vegan blends carry. There is no soy anywhere on it, no vitamin premix and no thickener, which is unusual in a range built on adding things. At 82p per 25g of protein it costs more than their whey blends, but casein always does, and this is a fair price for a single-ingredient micellar casein. The 4g of sugar per 100g is the only figure worth noting, and it is small in a 30g scoop.

Cheapest in-stock listing at a partner retailer, for packs of 400g and over. MyProtein Clear Whey Protein, Protein Works Vegan Protein 360 - GOLD Innovation, Protein Works Vegan Protein 360 - PLATINUM Innovation, Protein Works Vegan Pea Protein - BLACK Innovation, Protein Works 100% Micellar Casein - BLACK Innovation, Protein Works Diet Whey Protein Isolate - BLACK Innovation, Protein Works Clear Diet Whey Protein - GOLD Innovation have no partner listing in stock, so they carry no figure.
The whole ingredient list is micellar casein, flavouring and sucralose. No blend, no vitamin premix, no thickener, no emulsifier. Micellar casein gels in the stomach and digests slowly, which is the reason people buy it before bed rather than around training.

Flavoured versions add cocoa powder; the unflavoured is casein alone.
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.
No batch-testing claim is published for this product and we found none elsewhere.
Made by
Protein Works, produced at their own UK facility
What the maker does not publish
- Protein Works does not state the country of origin for the milk.
- We found no product-level buyer reviews we could attribute and link.
Questions buyers ask
The things people search for about Protein Works 100% Micellar Casein - BLACK Innovation, answered from the label and the live partner prices rather than from the brand’s own copy.
When should you take micellar casein?
It digests slowly, so the usual case is before bed or across a long gap between meals. Around training a faster protein makes more sense.
How much protein is in Protein Works Micellar Casein?
80g per 100g, or 24g in a 30g scoop.
Does Protein Works Micellar Casein contain soy?
No. The ingredient list is micellar casein, flavouring and sucralose, which makes it one of the few soy-free products in their range.
