L-CYSTEINE Mono HCI

Description

NDC: 53335-057-11 (capsule), 53335-058-29 (powder)

Weight: 4 Oz

L-Cysteine Monohydrochloride, the hydrochloride salt form of L-Cysteine, is a sulfur-containing non-essential amino acid that plays a vital role in numerous physiological processes. It supports the formation of hair, skin, and collagen, and serves as a precursor to glutathione, a powerful antioxidant essential for respiratory and immune health. This compound also contributes to the synthesis of taurine, an antioxidant important for myocardial health, and aids in detoxifying heavy metals while protecting the liver and brain from free radical damage caused by alcohol, drugs, and cigarette smoke. Research highlights its potential in promoting healing and immune function, particularly in burn and HIV patients (e.g., Droge et al. 1992).

L-Cysteine Monohydrochloride is particularly beneficial for individuals seeking to enhance antioxidant defenses, support tissue repair, or manage oxidative stress-related conditions. Its enhanced solubility due to the monohydrochloride form improves bioavailability. Manufactured using premium pharmaceutical-grade materials in a GMP-approved facility in the USA, L-Cysteine Monohydrochloride is free of fillers, binders, or coloring agents, with no known side effects when used as directed.

Directions: Take 1-3 capsules daily or as advised by your healthcare provider. Pair with vitamins and minerals. Powder equivalent: 1/4 level teaspoon per capsule.

Key Benefits

• Supports Antioxidant Health: Boosts glutathione and taurine production.
• Promotes Tissue Repair: Aids collagen and skin formation.
• Enhances Detoxification: Protects against heavy metals and free radicals.

Additional Information The following points provide insight into L-Cysteine’s plasma levels and their association with various health conditions, reflecting its role in metabolism:

• Normal Range: 50-200 micromol/L (approximate clinical range).
• Conditions Associated with Low Levels:
  • Malnutrition (due to reduced protein intake)
  • Chronic oxidative stress (e.g., chronic diseases like COPD)
  • Liver disease (impaired glutathione synthesis)
• Conditions Associated with High Levels:
  • Excessive supplementation (from overdosage or dietary excess)
  • Certain metabolic disorders (e.g., cystinuria, a genetic condition)
  • Acute inflammation or trauma (increased demand and release)

Notes: L-Cysteine Monohydrochloride is a precursor to glutathione and taurine, supporting antioxidant defense, detoxification, and tissue repair. It aids in heavy metal removal and protects against free radical damage, with potential benefits for immune function and healing in specific conditions like burns or HIV. Low levels may indicate nutritional or oxidative stress, while high levels can result from supplementation or metabolic imbalances. These associations are correlative and require further research for causal confirmation. Consult a doctor or medical professional before use, especially if you have underlying health conditions or are taking other medications.
