Not Vegan
How we decideSilk amino acids are not vegan. They are made by completely hydrolyzing silk protein, so the silkworm source remains relevant even after the protein is broken down.
Silk amino acids are small protein building blocks obtained by completely hydrolyzing silk. Silk itself is produced by silkworms to form cocoons.

A generic Amino Acids entry is not automatically silk-derived. The source word on the label is the practical distinction.
No. Amino acids can come from plants, microbes or animal proteins. The exact label name Silk Amino Acids identifies silk as the source.
