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.[1]

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.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Rated 4.5 out of 5 by 10 reviewers.
Rated 5 out of 5 by Try it for yourself . . . I tried Neurosilk based on the recommendation of a Swanson customer. I'm glad I did! I noticed an increase in my mental acuity almost from day one. It's now eight months later, and I wouldn't be without it. Neurosilk is pricey, which is its one downside. Still, it's definitely worth the cost. Big thumbs up. June 28, 2016
Rated 4 out of 5 by Stuck with this Brain I'm not sure how to rate certain things. How do I know if it is made with quality. I just have to trust that Swanson insists on quality, which I believe they do. As far as effectiveness, I'm not sure, as I haven't noticed anything dramatic as far as improvement in my lame brain. It does seem like it gives some clarity, especially after the second dose of the day. I've taken it for several months now, to give it time to work. I will probably stay with it, at least for a while longer. March 18, 2016
Rated 4 out of 5 by good stuff This is my second order of this product. It does the job. It just costs a lot. March 10, 2016
Rated 5 out of 5 by seems to be one of the only products on the market that is effective and priced reasonable February 4, 2016
Rated 4 out of 5 by still using I have been using this for about 2 months and really havent noticed any difference. I know sometimes it can take about 4 months to see results of supplements. Swanson offers very good products so i will continue to use for a couple more months and see what then. January 4, 2016
Rated 4 out of 5 by Very Advanced Supplement Swanson deserves a huge amount of recognition and credit for bringing such cutting edge supplements as this one!! Other companies that offer good prices don't match Swanson in this regard. Swanson is all about the health of their customers and they spare nothing!! In my case this supplement wasn't all I needed it to be BUT it may be great for you! October 31, 2015
Rated 5 out of 5 by best In enhancing memory, this is the most effective for me October 31, 2015
Rated 5 out of 5 by good & unique product i give swanson credit for coming up with this product, i have have been looking for some product with silkworm fibroin. but most of the products with silkworm from other brands i found are not trust worthy. since i trust swanson quality control,i like this product and research behind it. the only thing confusing to me is that they should mention how much silk fibroin it contains and how much glycine and alanine it contains. i am just assuming trumeric black pepper and coconut oil can enhance the absorption. all in all its a step in right direction and research is promising. October 21, 2015
Rated 4 out of 5 by Not the best "smart pills" Ill be honest and tell you that these do do what they advertise to do but there is something just as effective for ONE TENTH of the cost. GINKGO BILOBA. I had ordered this along with the neurosilk and i am more impressed with my ginko because of the impeccable value. For $6 you get 240 caps that are the same size as neurosilk. October 19, 2015
