What are Liposome NAC Drops?
Liposome NAC drops are a type of NAC supplement that uses microencapsulation technology to encapsulate the active ingredient within tiny phospholipid vesicles (liposomes). This structure is similar to human cell membranes, allowing NACs to more effectively cross the digestive barrier and directly enter the bloodstream and cells.
Compared to traditional NAC supplements, liposome NAC drops offer:
- 300% increased bioavailability - significantly improved absorption efficiency
- Stomach-friendly - reduces potential stomach discomfort
- Fast onset of action - works rapidly through sublingual absorption or mixing with drinks
- Precise dosing - the drop form allows for personalized dosage adjustments
Why Choose Liposome NAC?
1. Highly Effective Cell Protection
- NAC is a precursor to glutathione, the body's most important endogenous antioxidant. Liposome technology ensures that NAC is converted to glutathione to the maximum extent, providing powerful protection for your cells against oxidative stress and environmental toxins.
2. Respiratory Health Support
- For consumers in Europe and America who are concerned about respiratory health, NAC has been extensively studied and proven to help thin mucus and support respiratory tract cleansing. The liposomal form ensures that the active ingredient reaches target tissues more quickly.
3. Liver Health Maintenance
- In modern life, the liver bears metabolic stress. NAC supports the liver's detoxification pathway, promotes glutathione synthesis, and helps maintain healthy liver function.
4. Immune System Regulation
- NAC provides comprehensive support for immune health by regulating immune cell function and antioxidant status.
5. Cognitive Health and Mood Balance
- Emerging research suggests that NAC may support cognitive function and mood balance by regulating the glutamate system and antioxidant status.

- By supporting glutathione levels, NAC helps maintain normal immune cell function.
Liposome NAC Drops FAQ
Q: What is the regulatory status of NAC? What should OEM customers be aware of?
- A: The regulatory status of NAC in the United States is constantly evolving. The FDA has previously stated that NAC cannot be sold as a dietary supplement (because it was once approved as a drug). There is currently a grace period for enforcement, but OEM customers bear full responsibility for ensuring compliance in their target markets. We recommend that customers consult their legal and regulatory advisors before placing an order.
Q: What is the minimum order quantity (MOQ)?
- A: For standard formulations (100 mg/mL, unflavored), the MOQ is 1,000 bottles (based on 60 mL per bottle). For custom formulations (specific NAC concentrations, liposome parameters, solvent types, or flavors), the MOQ is 5,000 bottles.
Q: How do liposomal NAC drops prevent oxidation?
- A: NAC is a thiol compound and is prone to oxidation. We remove dissolved oxygen through nitrogen purging, use amber glass bottles to protect against light, maintain a pH of 4.0–5.0, and may add antioxidants such as citric acid. Accelerated stability testing confirms the product’s stability over a 24-month shelf life.
Q: Can the flavor of NAC drops be customized?
- A: Yes. NAC has a natural sulfuric/sour taste. We can add natural fruit flavors (lemon, orange, mint) and natural sweeteners (stevioside) to improve the taste.
Our Manufacturing Experience:
NAC (N-acetylcysteine) is a thiol compound that is prone to oxidation. As a manufacturer of liquid liposomes, we ensure the stability and efficacy of our products through the following measures:
- Liposome Preparation: Liposomes are prepared using the ethanol injection method or the thin-film hydration method. Particle size is controlled through high-pressure homogenization. We test particle size (DLS) and polydispersity index (PDI) for every batch, with standards of particle size < 200 nm and PDI < 0.3.
- Encapsulation Efficiency Testing: We use ultracentrifugation to separate free NAC from liposome-encapsulated NAC, and HPLC to determine the encapsulation efficiency (target ≥ 70%).
- Antioxidant Protection: NAC is prone to oxidation. We remove dissolved oxygen through nitrogen purging, use amber glass bottles to protect against light, and maintain the product’s pH between 4.0 and 5.0 (NAC is most stable within this pH range). Natural antioxidants (such as EDTA or citric acid) may be added for further protection.
- Stability Validation: Changes in particle size, encapsulation efficiency, and NAC content were monitored via accelerated stability testing (25°C/60% RH, 6 months).
- Customer Case Study: A U.S. brand required alcohol-free, vegan, and highly stable liposomal NAC drops. We developed a vegetable glycerin-water solvent system and, by optimizing the pH and adding citric acid, extended the product’s shelf life at room temperature to 24 months.
