Quick Buying Guide — Protein Powder

Type: Whey is fast-absorbing and ideal post-workout. Casein is slow-release, good before bed. Plant-based suits vegans.
Protein per serving: Look for at least 20–25g of protein per serving for effective muscle support.
Sugar content: Check the nutrition label — some flavoured powders contain high sugar levels.
Servings per bag: Compare cost per serving rather than total price — a bigger bag is not always better value.
Third-party tested: Look for NSF Certified or Informed Sport badges for quality assurance.
