Product Overview

L-Cysteine (Base) 99% Powder is a fine, blend-ready free-form amino acid with a mild sulfur-neutral taste that dissolves quickly in water, capsules, sticks and gummies—giving formulators a compact, clean-label option for everyday protein and movement routines. Each lot undergoes quality control for identity and key specifications (assay, micro, heavy metals, pesticide residues) and is packed under low-humidity, tamper-evident conditions to protect flow and purity. As a single-amino-acid ingredient, it offers predictable mg-per-serve math and minimal flavour impact in low-dose formats.

Grade: Food-grade.

Shelf-life: 18–36 months when stored below 77 °F (25 °C) < 60% RH in an airtight pack.

Form: Crystalline powder.
