Vitamin A forms include liposomal and nanoemulsion (gut friendly)
Liposomal Vitamin A
Liposomal vitamin A forms definitely exist and are commercially available. Liposomes are tiny spherical structures made of phospholipids that encapsulate nutrients, allowing them to be better absorbed by the small intestine. Vitamin A in liposomal form (typically as retinol or retinyl palmitate) is sold as a dietary supplement in liquid formulations. The liposomal encapsulation provides improved bioavailability compared to standard vitamin A formulations, with stability improvements of 30-55% better than pure non-encapsulated retinol. Researchers have also developed nanoliposomal vitamin A for targeted delivery, including formulations for bone health applications. The technology uses phospholipid bilayers to protect the vitamin and enhance its cellular absorption. pmc.ncbi.nlm.nih
Nanoemulsion Vitamin A
Nanoemulsion forms of vitamin A also exist in both research and commercial contexts. Nanoemulsions are thermodynamically unstable nanodroplets created from immiscible liquids (such as oil-in-water formulations) designed to deliver lipophilic compounds like vitamin A. Research published in peer-reviewed literature demonstrates preparation of vitamin A nanoemulsions using microfluidization techniques. A specific case study from Universitas Gadjah Mada documented development of a carrot extract nanoemulsion containing beta-carotene (provitamin A) for supplement purposes, selecting nanoemulsion technology specifically to maximize absorption of the pro-vitamin A in the body. ugm.ac
Both delivery systems address the same core challenge: vitamin A's fat-soluble nature and limited absorption when delivered in conventional forms. Nanoemulsions are particularly noted for excelling in topical delivery and rapid absorption, while liposomal systems are ideal for controlled release and high nutrient loading capacity. wbcil
