This L-tryptophan supplement from Viridian is suitable for vegetarians. L-tryptophan is an amino acid, a protein building block that can be found in many plant and animal proteins.
L-tryptophan is called an “essential” amino acid because the body can’t make it.
It must be acquired from food. L-tryptophan has been indicated in sleep disorders, smoking cessation, attention deficit hyperactivity disorder (ADHD), and anxiety.
