| Phospholipids | Emulsifier, e.g., phosphatidylcholine | |
| Water | Vehicle for dispersion | |
| Optional additives | Vitamins (A, D, E, K), omega-3 fatty acids |
Applications:
- Parenteral nutrition (TPN)
- Drug carriers and targeted delivery systems
- Lipid replacement therapy (e.g., omega-3 supplementation)
- Clinical management of nutritional deficiencies and metabolic disorders
