Brain-boosting formula for maximizing your mental power
Supports natural cognitive function

Optimize your memory and mental performance with the natural brain nourishment of Swanson Ultra NeuroSilk with Brain Factor-7. 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.
NeuroSilk features Brain Factor-7 (BF-7), a unique brain-nourishing peptide found naturally 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. BF-7 is produced through an enzymatic hydrolysis process that isolates silk’s fibroin peptides to deliver purified, concentrated brain nourishment.
BF-7 peptides can be classified as “quintessential beta sheet peptides.” Beta sheet sequences work together continuously as a means of moving, attaching/detaching, and activating/deactivating other proteins to ensure they reach their full potential. BF-7 peptides are superior among these types of sequences because they are molecularly smaller and have different properties. For example, stronger hydrogen bonding, less steric hindrance, more penetration of protein chains, and stronger hydrophobicity are several properties that place BF-7 peptides apart from others. In reactions with other amino acids, these peptides act like “Molecular Velcro®.” In short, this “Velcro®” enhances receptor functions and supports biological systems.
BF-7 is packed with glycine and alanine, which are important amino acids for healthy neurotransmitter function and cellular energy production, but the key to its brain-boosting power lies primarily in its unique physical structure. BF-7 peptides feature beta-pleated sheet amino acid sequences that enable them to interact with signaling receptors in cell and nuclear membranes. Their small size allows BF-7 peptides to readily cross the blood-brain barrier, where they can interact directly with beta-pleated sheet structures in brain cell membranes to support cognitive function. Outside of the brain, BF-7 can also have favorable interactions with beta-pleated protein components involved in healthy circulatory and insulin function.
The natural nourishment of BF-7 can provide a valuable mental boost for young and old alike. Human studies on the effects of BF-7 on memory and mental function conducted in Korea have shown positive results in healthy young adult, middle-aged and elderly subjects. Wherever you fall on the age spectrum, with NeuroSilk, you can give your brain a nutritional advantage to make the most of your mental capacities.
