Dymatize ISO100 Hydrolyzed Whey ...

Pros

  • Excellent mixability — reviewers consistently note it blends smoothly without clumping or leaving a thick texture
  • Great taste across flavours — H&B reviewers praise it as genuinely enjoyable, not just tolerable
  • Hydrolyzed formula for faster absorption — ideal post-workout when rapid amino acid delivery matters
  • Very clean macros — 25g protein, <1g sugar, <1g fat, 120 kcal per serving with 5.5g BCAAs including 2.7g leucine (above MPS threshold)

Cons

  • Premium price point — explicitly flagged by reviewers and among the most expensive isolates per serving
  • Can be overly sweet at standard dilution — one reviewer recommends 450ml water per scoop rather than the suggested amount
  • Contains soy lecithin — minor concern for those avoiding soy entirely
  • Uses sucralose (artificial sweetener) alongside stevia — not suitable for those avoiding artificial additives

Best For

Athletes and competitive sports people requiring certified clean protein Post-workout recovery — hydrolyzed form absorbs faster than standard isolate Lactose-sensitive individuals — isolate process removes virtually all lactose Those prioritising protein purity and minimal calories over cost Experienced gym-goers tracking macros precisely

  • High protein yield (~24g per serving) with low fat and sugar content, suitable for calorie-controlled diets
  • Consistently reported improvements in muscle recovery and reduced post-workout soreness
  • Whey protein isolate as primary ingredient ensures high purity and lower lactose versus concentrate-based alternatives

Cons

  • French Vanilla Creme described as slightly bland when mixed with water; better suited to milk
  • Occasional fulfilment issues reported (missing scoop, container appearing half-filled)
  • Contains fish and milk allergens — unsuitable for those with relevant sensitivities

Best For

Regular gym-goers and athletes seeking post-workout recovery People on calorie-controlled or high-protein diets Those managing blood sugar who need a low-sugar protein source Beginners looking for a reliable, well-established brand Users who prioritise mixability and daily drinkability

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.
