Improve Fat-Soluble Vitamin Absorption with Nutritional Emulsifiers
The bioavailability of fat-soluble vitamins can be increased with the inclusion of a nutritional emulsifier – or biosurfactant – in the final feed. Alongside bile salts, biosurfactants work to form smaller, more stable oil-in-water emulsion droplets that are more effectively hydrolyzed and absorbed than with bile alone.5
Use of biosurfactants – polysorbates, lecithin, lysolecithins, etc. – can especially be beneficial for young animals which have limited ability to digest and absorb dietary fats and fat-soluble nutrients, like vitamins, carotenoids and pigments.5 For example, lysolecithins have been shown to improve vitamin E uptake in eggs8 as well as enhance collagen deposition and increase jejunum villus length in broilers.9
Maximizing vitamin absorption is key to ensure your animals get the vitamins they need for optimal health and performance. To optimize conditions for vitamin uptake, using protected vitamins and managing gut health are key. Additionally, improving emulsification can lead to more efficient fat-soluble vitamin uptake. Use of a lysolecithin-based nutritional emulsifier like LYSOFORTE® can help producers to optimize digestion and absorption of fats and fat-soluble nutrients thereby:
- Enhancing the uptake of fat-soluble ingredients like vitamins and carotenoids
- Maximizing utilization of energy from oils and fats
- Improving animal performance to offer better feed cost control
