How do your amino acid tables fit in?
Amino acid tables are provided by raw material manufacturers. They’re usually based on 100 g of pure protein, not 100 g of protein powder (which is typically 75–90% protein).
These tables are averages, not batch-specific, and are best used to compare protein types, not brands. For example:
- Whey proteins are naturally higher in BCAAs than plant proteins.
- Collagen contains much more glycine than other proteins.
Once you’ve chosen your protein type, amino acid levels scale with total protein. For example, if our WPI has 3% more protein than another brand, it will also have about 3% more leucine, valine, and other amino acids.
