Frequently Asked Questions (FAQ) – Protein Guide 2026

What is the difference between Concentrate, Isolate, and Hydrolysate?
- Concentrate: Most affordable, contains some lactose.
- Isolate: Filtered to remove almost all lactose and fat.
- Hydrolysate: “Pre-digested” for the fastest possible absorption.

Absolutely. High-end vegan proteins are now fortified with specific amino acids to match the muscle-building profile of dairy-based whey.
