Description

S-Methyl Ergothioneine is a potent, naturally occurring sulfur-containing derivative of the amino acid ergothioneine. This compound is valued for its enhanced stability and bioavailability compared to its parent molecule, making it a superior choice for advanced nutraceutical and cosmeceutical formulations. It is primarily sought by manufacturers in the dietary supplement, functional food, and high-performance skincare industries seeking to leverage its powerful antioxidant and cytoprotective properties.

Application

• Dietary Supplements: As a key bioactive ingredient in capsules, tablets, and powders for antioxidant support and cellular health.
• Functional Foods & Beverages: Fortification of health drinks, nutrition bars, and other food products to enhance their nutritional profile.
• Cosmeceuticals & Skincare: Incorporated into anti-aging serums, creams, and lotions for its skin-protective and anti-inflammatory benefits.
• Pharmaceutical Research: Used as a reference standard or active pharmaceutical ingredient (API) intermediate in preclinical and clinical studies.
• Biochemical Research: Employed as a tool compound in studies of oxidative stress, aging, and metabolic pathways.

Quality Control

Our S-Methyl Ergothioneine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for high-grade applications. Certificates of Analysis (COA) documenting purity, heavy metals, residual solvents, and microbiological parameters are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
