Buying Guide
What should I look for in a whey protein isolate?
- Protein per serving: Aiming for 25-30g per serving is common for protein powders intended for post-workout recovery and daily supplementation.
- Ingredient quality: Look for minimal artificial additives, and consider grass-fed sources if you want a cleaner label.
