Spermidine is a polyamine compound that is naturally present in all living cells, including plants, animals, and microorganisms. It is a by-product of amino acid metabolism, and amino acids are components of proteins. Spermidine plays multiple roles in the body and contributes to various important biological functions. One of its main functions is to participate in cell growth and proliferation. Spermidine is crucial for maintaining the stability of cellular genetic material DNA and RNA, and it is involved in the regulation of gene expression. Additionally, spermidine has been proven to have antioxidant properties, which can protect cells from oxidative damage and contribute to overall cellular health. Moreover, spermidine is involved in the regulation of immune responses and is related to the regulation of inflammation. The multifaceted nature of spermidine's functions highlights its importance in maintaining overall health and well-being.

• High purity: Spermidine can be produced with high purity through a refined production process. High purity implies better bioavailability and fewer adverse reactions.

• Safety: High safety with few adverse reactions.

• Stability: Spermidine has good stability and can maintain its activity and efficacy under different environments and storage conditions.

In recent years, spermidine has attracted attention due to its potential applications. Spermidine extensively inhibits the immune responses mediated by JAK1 in type I and type II cytokines and their inflammatory effects. Spermidine directly binds to the JAK1 protein, inhibiting the binding of JAK1 to related cytokine receptors, thereby blocking the activation of the downstream signal transduction pathways of cytokines, and exerting immunosuppressive and anti-inflammatory effects.
