Tryptophan 300 mg by OstroVit is a dietary supplement based on the amino acid L-tryptophan. Tryptophan is an organic chemical compound from the group of essential amino acids, which cannot be synthesized by the body. To ensure the proper level of tryptophan, it must be provided through food or supplements. It is an important amino acid found in many proteins.

Tryptophan is a precursor to serotonin, a neurotransmitter essential for regulating appetite, sleep, mood, and pain. It also contributes to platelet aggregation and acts as a natural sedative.

Tryptophan is also a precursor to melatonin, which is important for regulating the sleep-wake cycle. Its supplementation can support individuals experiencing insomnia and those who wish to improve their mood and support their nervous system.
