Key Production & Formulation Considerations
1. Moisture Control: Glutathione is sensitive to humidity; keep powders dry during storage and mixing.
2. Temperature Sensitivity: Avoid high temperatures (>40°C) during processing; can cause oxidation.
3. pH Range: Optimal stability in slightly acidic formulations (pH 3.5–5.5).
4. Compatibility: Test interactions with vitamins, minerals, and other active ingredients to prevent degradation.
5. Particle Size & Solubility: Fine, uniform powder ensures even blending in capsules, beverages, or creams.
6. Packaging: Use moisture-proof, airtight containers; protect from direct sunlight to maintain potency.
Common Applications
1. Dietary Supplements: Capsules, tablets, or powders for systemic antioxidant support, immune health, and overall wellness.
2. Functional Beverages: Water-soluble GSH can be added to drinks, energy powders, and health shots.
3. Cosmetic & Skincare Products: Creams, serums, or masks for skin brightening, reducing oxidative stress, and anti-aging effects.
4. Nutricosmetics: Combined with vitamins, minerals, or other antioxidants to enhance skin and wellness benefits.
Recommended Dosage
1. Dietary Supplements: Typically 100–300 mg per serving, depending on target market and formulation type.
2. Functional Beverages: 50–150 mg per serving, ensuring solubility and stability in liquid form.
3. Cosmetic Formulations: 0.5–2% of final product weight, adjusted based on skin tolerance and product type.
*Always validate final dosage according to regulatory guidelines in target markets.
FAQs
1. Does it work in beverages without degrading?
Use stabilized, reduced glutathione; avoid prolonged heat or high pH. Add at the last stage of mixing for maximum potency.
2. Will it affect taste or color?
GSH is slightly sulfurous; flavor masking or encapsulation can help. White crystalline powder maintains product appearance if handled correctly.
3. How to maintain efficacy in creams or serums?
Use pH 3.5–5.5 formulations, avoid strong oxidizers, store in airtight, light-protected containers.
3. How to ensure batch-to-batch consistency?
Work with suppliers providing CoA, stability testing, and particle size control to maintain uniformity.
