Nutraceutical capsules are a convenient way to deliver nutritional compounds and are formulated to supplement the diet and support health. These capsules often contain a blend of vitamins, minerals, amino acids, and herbal extracts to target specific health concerns like improving immune function, cardiovascular health, and cognitive function. They are used for both preventing disease and enhancing body functions beyond what a normal diet provides, with a wide range of specific applications from managing metabolic syndrome to supporting joint health.
