Tag: Vegan amino acids

Did you know that the vegan status of L-histidine depends entirely on how it is produced or where it comes from? While this essential amino acid is necessary for human health, its origin is not always plant-based, making it crucial for vegans to confirm their sources.

According to a 2025 study in *PLOS ONE*, while most long-term vegans meet total protein requirements, up to half may fall short on key amino acids like lysine and leucine when accounting for digestibility.

Fundamentally, all amino acids originate from plants, making them the primary source for vegans. Modern supplements also offer a way to get these essential nutrients.
