Silk Protein Hydrolysate Complex
Also known as: Silk Fibroin Enzyme Hydrolysate, FEH, Bombyx mori protein hydrolysate, Silk Protein Hydrolysate Complex
Overview
Silk Fibroin Enzyme Hydrolysate (FEH) is a bioactive protein derived from silk fibroin, which is sourced from the cocoons of the silkworm Bombyx mori. The production process involves enzymatic hydrolysis, leading to a mixture of peptides and amino acids that enhance bioavailability. This supplement is primarily noted for its potential cognitive enhancement benefits, particularly in areas such as memory, learning, attention, and overall mental clarity. Emerging research supports its application across various age groups, from children to seniors. The neuroprotective properties of FEH are of considerable interest, as it appears to influence biological pathways associated with oxidative stress and inflammation, highlighting its promise for supporting cognitive health.
Benefits
Silk Fibroin Enzyme Hydrolysate has been shown to significantly improve cognitive function. Human studies indicate enhancements in memory, learning, attention, and mental focus when supplemented with doses of 200-600 mg for a period of 3 to 16 weeks. Animal studies support these findings, showing that FEH can reverse cognitive impairments caused by scopolamine, largely by promoting neuroprotective factors like brain-derived neurotrophic factor (BDNF) while reducing pro-inflammatory cytokines. This demonstrates FEH's effectiveness across a wide demographic (ages 7 to 92), although further research is needed to define the clinical significance and detailed effect sizes in various populations.
How it works
The cognitive-enhancing effects of Silk Fibroin Enzyme Hydrolysate are attributed to its potent antioxidant and anti-inflammatory properties. FEH protects cholinergic neurons from oxidative stress, leading to elevated levels of acetylcholine, a neurotransmitter critical for learning and memory. Additionally, it enhances the expression of neurotrophic factors such as BDNF and phosphorylated cAMP response element-binding protein (p-CREB), which are essential for neuronal survival and synaptic plasticity. These mechanisms collectively influence central nervous system functions, thereby improving cognitive capabilities.
Side effects
Silk Fibroin Enzyme Hydrolysate is generally well-tolerated, with research indicating no significant adverse effects associated with its use. Reported side effects are minimal (<5%), while uncommon effects fall within the range of 1-5%, and rare adverse effects account for less than 1%. Notably, no substantial drug interactions or contraindications have been identified for FEH. However, the limited data on its safety during pregnancy and lactation, as well as its use in individuals with certain medical conditions, necessitates further investigation to better assess its long-term safety profile.
Dosage
The effective dosage for Silk Fibroin Enzyme Hydrolysate typically ranges from 200 to 600 mg per day. Clinical studies suggest cognitive benefits can be expected within 3 to 16 weeks of supplementation within this dosage range. No established upper limits or maximum safe doses have been identified, as no adverse effects have been reported in this dosage range. There are no specific recommendations concerning timing for intake, allowing for flexible administration. FEH is commonly available in powdered or capsule forms. Enzymatic processing is noted to enhance absorption, though additional studies are required to fully understand its absorption characteristics.
