Phospholipids act as natural emulsifiers and absorption enhancers
Phospholipids act as natural emulsifiers and absorption enhancers in functional foods, significantly improving the bioavailability of poorly soluble nutrients (e.g., fat-soluble vitamins, omega-3 fatty acids, probiotics):
Fat-Soluble Nutrients: Phospholipids form micelles with fat-soluble vitamins (A, D, E, K), carotenoids (lycopene, β-carotene), and omega-3 fatty acids (EPA, DHA), increasing their solubility in the gastrointestinal tract. For example, adding soy lecithin to omega-3 supplements improves DHA absorption by 30–40% compared to standalone DHA formulations.
Probiotics: Phospholipids (e.g., phosphatidylcholine) form a protective coating around probiotic cells, shielding them from stomach acid and bile salts. Functional yogurts or probiotic supplements containing phospholipids show a 2–3-fold increase in probiotic survival rate through the gastrointestinal tract, enhancing their colonization in the gut.
Herbal Extracts and Bioactive Compounds: Phospholipids improve the solubility and permeability of poorly bioavailable ingredients such as curcumin, resveratrol, and ginseng saponins. For instance, curcumin-phospholipid complexes in functional foods increase curcumin bioavailability by 10–20 times, enhancing its anti-inflammatory and antioxidant effects.
