Injectable Nutraceuticals: A Novel Frontier in Preventive Health

Abstract

The world has become more susceptible to micronutrient deficiency and lifestyle diseases in most cases, creating a need to find viable ways of intervening with nutraceuticals. Nevertheless, oral nutraceuticals have significant disadvantages that include low bioavailability, gastrointestinal degradation, unreliable absorption, and compliance. These limitations have heightened the concern on injectable nutraceuticals which is a growing category of parenterally administered vitamins, minerals, peptides, antioxidants and botanical extracts products designed to reach rapid and consistent systemic concentrations. This review brings out the scientific justification, development of formulations and pharmacokinetics advantages of injectable nutraceuticals. Contemporary approaches to delivery such as liposomes, nanoemulsions, cyclodextrin complexes, microspheres, hydrogels, and biopolymer-based carriers play a significant role in increasing the solubility, stability, and prolonged release of bioactive compounds. Mechanically, injectable nutraceuticals have antioxidant, anti-inflammatory, immunomodulatory, and metabolic regulatory effects, which support their use in preventive and integrative care. They are particularly useful in special populations like malabsorption disorders patients, post-operative patients, and patients with high metabolic rates. The threats to their promise can still be seen in the regulatory uncertainty, lack of clinical evidence, and ethical issues in wellness environments, and compliance with GMP should be considered strict. Altogether, injectable nutraceuticals have significant potential of developing precision, high-bioavailability preventive therapies by further research and regulation perfection.
