Decision snapshot
Know the basis before the button.
This summary keeps suitability, evidence status and commercial context above the retailer action so the product link never becomes the whole assessment.
Evidence status
Product facts reviewed
Uses the product identity, specifications and limitations shown on this page; no research or hands-on testing is claimed.
Hands-on testing
Not claimed
NST should only show a tested badge when a repeatable test record exists for the exact product.

Consider it if
Adults who use dairy, need a convenient way to close a dietary protein gap and are comfortable with the milk and emulsifier allergen profile.
Skip it if
People who already meet their protein needs through food, need a dairy-free product, react to milk or soy, or expect a guaranteed lactose-free product.
Check before buying
NST has not independently tested label accuracy, banned substances, lactose, taste, mixability, digestibility, packaging or outcomes.
Why it is included
The NST assessment
This exact UK candidate has a current manufacturer label panel, and the Impact Whey Isolate product line appears in independent Informed Choice and Informed Protein directories. Inclusion is not an endorsement; the exact physical pack and certification marks still require review.
Assessment basis
This assessment uses the product identity, specifications and limitations reviewed for this exact record. It does not claim hands-on testing unless that testing is stated explicitly on this page.

Advantages and trade-offs
Advantages
- The current manufacturer page provides a variant-specific panel for the 900 g unflavoured product.
- Impact Whey Isolate (Global excluding USA and Canada) appears in independent Informed Choice and Informed Protein product directories; the exact purchased pack and batch marks must still be checked.
Limitations
- NST has not independently tested label accuracy, banned substances, lactose, taste, mixability, digestibility, packaging or outcomes.
- No quantified lactose value was found on the checked label panel; the product must not be called lactose-free.
- Product-line directory listings must not be presented as proof that NST verified every flavour, pack or production batch.
- The physical label, exact certification marks, current availability and any intended retailer match must be checked before an approved publication.
- No price, star rating, review count, stock statement, affiliate link or retailer image is recorded.
Alternatives before buying
Whole-food protein sources and other suitable dairy or plant protein powders can cover the same dietary gap. This record establishes no brand or isolate-format advantage.
