Support healthy cognition with Swanson NeuroSilk. Much like a high-performance engine, your brain works best when it gets premium-grade fuel. And NeuroSilk fuels your brain like nothing else can.
Swanson NeuroSilk features fibroin, a unique peptide found in silk. The Chinese have been breeding silkworms for silk production for more than 5,000 years, and silkworm cocoons have been used for health purposes for nearly as long. In its raw state, silk consists of two main proteins, sericin and fibroin, with a glue-like sericin layer surrounding tough central filaments made of fibroin.
Silk fibroin is primarily composed of the amino acids glycine, alanine and serine, which are important for healthy neurotransmitter function and cellular energy production. These fibers have a unique structure that enables them to interact with signaling receptors to deliver effective cognitive support, specifically for attention and learning. Silk protein products have been studied for their neuroprotective and antioxidant properties which may benefit healthy brain function such as focus, recall and concentration. Swanson NeuroSilk delivers 200 mg silk fibroin in each single-capsule serving.
