Phospholipid Powder
Phospholipids (e.g., lecithin, phosphatidylcholine) act as natural carriers for fat-soluble compounds, addressing their poor solubility and low absorption in the digestive tract. This is particularly valuable for supplements containing:
Omega-3 fatty acids (EPA/DHA): These essential fatty acids are prone to oxidation and have limited water solubility. Phospholipids form micelles or liposomes around omega-3s, improving their dispersion in aqueous environments (e.g., in liquid supplements or softgels). Studies show phospholipid-complexed omega-3s have 20–50% higher bioavailability than conventional formulations, enhancing their delivery to tissues like the brain and heart.
Fat-soluble vitamins (A, D, E, K): Phospholipids facilitate the absorption of these vitamins in the small intestine by mimicking the body’s natural lipid absorption pathways. For example, vitamin D3 paired with phosphatidylserine in supplements shows increased uptake, supporting bone health and immune function more effectively.
Lipophilic antioxidants (curcumin, resveratrol): Compounds like curcumin have poor bioavailability due to low solubility and rapid metabolism. Phospholipid complexes (e.g., curcumin-lecithin) enhance their solubility in gastrointestinal fluids and promote uptake by intestinal cells, boosting their antioxidant and anti-inflammatory effects.
