What the Data Says

What makes a clean whey protein? Ingredient quality scores across 169 UK products

Fewer ingredients = cleaner protein. We scored 169 whey proteins on ingredient quality (IQ) and the gap between top and bottom is massive: 65 points, from 95/100 down to 30/100.

The top 7 products by IQ all share one trait — minimal ingredient lists:

  • PINK SUN Organic Whey Concentrate — IQ 95, overall 85
  • Isopure Unflavoured Whey Isolate — IQ 91, overall 76
  • LEGION Whey+ Isolate — IQ 91, overall 80
  • PINK SUN Whey Isolate Unflavoured — IQ 91, overall 81
  • Purition 100% Whey Isolate 93% Protein — IQ 91, overall 80
  • Dymatize ISO100 — IQ 90, overall 84
  • Naked Whey (1 ingredient) — IQ 90, overall 74

The bottom tells the opposite story. Products like BodyFuel Clear Protein (IQ 30), Amfit Nutrition (IQ 38), and Protein Dynamix 3XP (IQ 38) use multi-source protein blends padded with artificial sweeteners, thickeners, and colourings.

The average across all 169 products is 70.7/100. If your whey protein has more than 5-6 ingredients, check what's filling up that list. A clean whey needs protein, maybe a natural flavour, and not much else.

Can cheap whey protein cause bloating? What to check on the label

Cheap whey often causes bloating because of what's added to the protein, not the protein itself. We scored 169 whey proteins and the worst-scoring products share the same filler-heavy ingredient profiles.

Three categories of additives show up repeatedly in low-IQ products (scored 30-42):

  • Thickeners — xanthan gum, carrageenan, cellulose gum. These bulk up texture but can cause gas and bloating in sensitive stomachs.
  • Artificial sweeteners — sucralose, acesulfame-K, aspartame. Linked to gut microbiome disruption in some studies. Budget brands use these heavily.
  • Anti-caking agents and emulsifiers — added to improve mixability, but another source of digestive irritation.

Products like BodyFuel Clear Protein (IQ 30), Amfit Nutrition (IQ 38), and SCI-MX Ultra Muscle (IQ 42) stack several of these additives together.

Compare that to the top scorers: PINK SUN Organic Whey (IQ 95) and Naked Whey (IQ 90) use 1-3 ingredients total. No thickeners, no artificial sweeteners, no fillers. Users report far less digestive trouble with these minimal formulas.

Label check shortcut: flip the tub over. If the ingredient list has more than 6 items, or you spot carrageenan, sucralose, or acesulfame-K, that's your likely bloating culprit. A whey isolate with a short list costs a bit more but your gut will thank you.
