Biologically active substances that come from animals and have positive impacts on human health are known as animal-based bioactives. The potential health advantages of bioactive compounds derived from animals have received considerable attention. These compounds include collagen, iron, conjugated linoleic acid, vitamin B12, omega-3 fatty acids, carnosine, creatine, etc. These bioactive substances exhibit potential health benefits such as immunomodulatory, anti-inflammatory, antibacterial, antioxidant, and anti-cancer properties. Advancements in this sector recently have illuminated the wide array of health advantages. Bioactive compounds derived from animals have increased scientific comprehension and created novel possibilities for their applications as functional foods, nutraceuticals, bioactive peptides to support gut health, and the development of drugs. To fully comprehend their modes of action, recommended dosages, and any side effects, more research is necessary. Developments in animal-based bioactives have demonstrated promise for use in nutrition, nutraceuticals, medicine, and functional foods. The objective of advancements and new trends is to develop innovative products from animal-based bioactive compounds that enhance overall health and wellness.
