Soya Protein Isolate & Protein Content

Impact Soy Protein uses soya protein isolate as its defining protein source. Protein contributes to the growth and maintenance of muscle mass and can help increase daily protein intake around training or as part of your everyday diet.

The exact protein amount varies by flavour. Chocolate Smooth, Salted Caramel, Natural Strawberry and Vanilla provide 23g protein per 30g serving, Milk Tea provides 24g, and Unflavoured provides 25g.

How & When to Use Impact Soy Protein

Mix 30g with approximately 300ml of water or milk alternative. It can be used around training, including before or after exercise, or whenever additional protein intake fits your nutrition.

Powder can settle over time, so weighing the serving gives the most accurate measure.

Store in a cool, dry place away from direct sunlight and use alongside a varied, balanced diet and healthy lifestyle.
