Consider it if
Adults seeking a plant-based protein powder after checking the current ingredients, allergens and nutrition against their overall diet.
Skip it if
People already meeting protein needs through food, anyone who avoids soy, or readers who have not checked the label for individual dietary or medical suitability.
Check before buying
NST has not independently tested composition, amino-acid availability, batch consistency, digestibility, taste, muscle gain, recovery or suitability.
Why it is included
The NST assessment
This exact current UK variant replaces a generic soy-isolate placeholder so its format, serving basis and label boundaries can be checked. Inclusion does not establish superiority or a muscle outcome.
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.
Who this is for, and who can skip it

Advantages and trade-offs
Advantages
- Myprotein identifies the exact product as Impact Soy Protein, an unflavoured 500 g ready-to-mix soy-protein-isolate powder.
- The displayed manufacturer panel lists 25 g protein per 30 g serving, 16 servings per pack, and labels the variant suitable for vegetarians and vegans.
Limitations
- NST has not independently tested composition, amino-acid availability, batch consistency, digestibility, taste, muscle gain, recovery or suitability.
- Nutrition and ingredients may differ across flavours or reformulations; the current physical pack label controls.
- Soy is an allergen and suitability cannot be inferred from the vegan label alone.
- No price, rating, review count, affiliate link or manufacturer image is recorded.
Alternatives before buying
Protein-rich foods, pea or blended plant proteins, or dairy-based powders may suit different diets, allergens and preferences.
