Serine is a naturally occurring amino acid that is primarily used in the pharmaceutical, health supplement, and cosmetic industries to contribute to nervous system health, cell repair, and normal metabolic function.
Product Advantages
High Purity
Serine is extracted using supercritical CO2 extraction, achieving a purity exceeding 99.5%, thereby enhancing bioavailability.
High Activity
Low-temperature extraction prevents the destruction of active ingredients by high temperatures, preserving over 90% of their natural bioactivity.
Low Heavy Metal Content
Using an ion exchange purification process, lead levels are ≤ 0.1 ppm, cadmium ≤ 0.05 ppm, and mercury ≤ 0.01 ppm, ensuring food safety.
