How do I choose a protein powder for my diet?

Compare the protein source, protein per serving, ingredients and format. Start with your usual diet and tolerance of the ingredients.

Check the serving weight: different manufacturers use scoops that hold different amounts. Compare the nutrition per 100 g as well as per serving.

Check allergens, sweeteners and flavour. A larger pack is not always better value: calculate the cost per serving. Protein powder supplements a diet rather than replacing all meals.
