Buying Guide

What to consider when choosing a casein powder for women:

• Ingredients and purity: Look for micellar casein as the primary protein source and minimal additives. NSF certification (where available) signals purity.
• Flavor and texture: Nighttime shakes benefit from flavors you’ll actually enjoy. If texture is important, opt for brands emphasizing smooth mixability.
• Protein per serving: Most products provide around 24–25 g per serving. Consider total daily protein goals and how the serving aligns with your meal timing.
• Dietary considerations: Check for dairy-based ingredients, soy, gluten, and artificial additives if you have sensitivities or dietary preferences.
• Value and serving size: Compare price per serving and container size to estimate long-term cost, especially for daily use.
• Purity and sourcing: Some shoppers prefer cold-processing and US-sourced ingredients for perceived quality and safety.
• Usage timing: Casein digests slowly, making it ideal for bedtime, long gaps between meals, or as a protein bridge between workouts.

Frequently Asked Questions

1. What is micellar casein and why is it used at night?
