The popularity of nanocarriers is increasing at a higher pace due to their potential benefitsBenefits. The application of nanocarriers in food and nutrient delivery is an area of profound interest. When nanocarriers are administered into the biological system, their bioavailabilityBioavailability (enhanced) and effectivenessEffectiveness increase manifold. Improving solubility, stability, controlled release, site-specific delivery, and biodistribution increases the utilisation of nutrients or drugs. Among these nanocarriers, liposomes, nanoemulsions, and solid lipid nanoparticles (SLNs) are most commonly used for nutrient delivery. Their physical and chemical properties control the mechanism of interaction of nanocarriers with nutrients. Nanocarriers in nutrient delivery aim to enhance healthHealth and wellness, treat nutritional deficiencies, and support medical therapies. The role of nanocarriers in sports nutrition is quite remarkable. They enhance exerciseExercise performance and endurance amongst athletes by meeting their nutritional needs, which are significantly higher than an average individual. More clinical trials on humans are needed, which will help to understand the effectivenessEffectiveness of nanocarriers and promote the developmentDevelopment of advanced formulations.
