Mixed on the numbers
Scored on the label and the price, not on how it tastes. How we score.
How the numbers stack up against the price
£1.37 buys 25g of protein here, which makes it the 16th cheapest of the 18 powders we have reviewed, behind Warrior Whey at £1.19, and 51p over the median.
It is also the only product of theirs where the added micronutrients are dosed at 100% of the reference intake rather than 15%, though there are only four of them. The added acetyl-L-carnitine and green tea extract are what earn it the "diet" name and neither has strong evidence for fat loss at the doses used here, so buy it for the macros rather than the actives. At £1.37 per 25g of protein on Protein Works’ own 1kg bag it is not cheap, and it comes only in 500g and 1kg, so there is no big-bag discount to reach for. It is also the one product in the range where Amazon undercuts Protein Works, at £1.18 against £1.37, so it is worth checking the retailer table below before you buy.

Cheapest in-stock listing at a partner retailer, for packs of 400g and over. NXT Nutrition Beef Protein Isolate has no partner listing in stock, so it carries no figure.
A clear-format whey isolate, so it mixes to a juice rather than a milkshake. One protein source, and the rest of the list is what makes it a "diet" product: acetyl-L-carnitine, green tea extract, and a four-item vitamin and mineral blend of B5, B6, chromium picolinate and B12. Citric acid and anti-foaming agents do the clear-drink work. No soy protein and no lecithin at all.
What the label gets right, and wrong
Strengths
- 0.1g of fat and 0.3g of sugar per 100g, the leanest macro line in the range
- 82g of protein per 100g from whey isolate alone
- Four micronutrients dosed at 100% of the reference intake, against 15% on the 360 range
- 0.10g of salt per 100g
Watch-outs
- £1.37 per 25g of protein at Protein Works, rising to £1.46 on the 500g bag
- Only two pack sizes, so no bulk saving
- The acetyl-L-carnitine and green tea extract are not well evidenced for fat loss at these doses
- A clear format is a texture preference, not a nutritional advantage
Where to buy it
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.

What a scoop actually contains
Taken from the manufacturer’s published label. Source.
Panel as published for the Blue Raspberry flavour. Other flavours on the page run 80g to 83g protein per 100g with carbohydrate between 0.7g and 1.9g, so the macro line is tight across the range. The four micronutrients are listed at 100% of the reference intake per 25g serving, not the 15% the 360 range uses.

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 dose of acetyl-L-carnitine or green tea extract per serving.
- We found no product-level buyer reviews we could attribute and link.
Questions buyers ask
The things people search for about Protein Works Clear Diet Whey Protein - GOLD Innovation, answered from the label and the live partner prices rather than from the brand’s own copy.
What is clear whey protein?
Whey protein isolate formulated to dissolve into a translucent juice-style drink rather than a milkshake. Nutritionally it is isolate; the difference is texture and the acids and anti-foaming agents that make it behave that way.
Does Clear Diet Whey actually help with dieting?
The macros do: 86 kcal and 20g of protein in a serving, with almost no fat or sugar. The acetyl-L-carnitine and green tea extract that give it the name are not well evidenced for fat loss at the doses used in protein powders, and the doses are not published.
How much protein is in Protein Works Clear Diet Whey?
82g per 100g, or 20g in a 25g serving, on the Blue Raspberry panel. Other flavours run 80g to 83g.
