Depends on Source
L-Arginine and Other Amino Acids
An amino acid supplement that can come from microbial fermentation (safe) or animal-derived extraction.
Why this is a critical point
Amino acids such as L-arginine, L-glutamine, or L-lysine are widely used in fitness supplements and food fortification. Modern production is mostly bacterial fermentation (halal), but some low-cost suppliers still extract them from animal sources such as feathers or blood.
