Nutraceuticals are usually natural therapy products marketed for their effectiveness in improving the overall health and function of the human body. Although, the Food and Drug Administration (FDA) didn’t classify nutraceuticals as drugs because many of these products do not have the therapeutic effects of drugs beyond what you’d ordinarily expect from food sources. Nutraceuticals are entirely different from pharmaceuticals as their purpose isn’t to treat or cure a disease in the human body. However, the word “nutraceutical” is mostly used on products that are marketed and sold in the form of capsules, pills, liquid supplements, and powders. The liquid supplements may include whole food supplements like meal replacement shakes, diet shakes, protein powders, and more. The Food and Drug Administration is charged with the sole responsibility of providing regulations for the safety of nutraceuticals and their process of manufacture, distribution, and sales, as with other products. Therefore, manufacturers of these products must fully comply with the strict guidelines and regulations provided by the FDA. Depending on the nutraceutical products, the regulations and guidelines vary considerably. A typical example is gluten supplements which can be used as fillers or coating for most dietary supplements. However, most products also require pesticide levels below specified limits in line with FDA regulations. Above all, manufacturers of nutraceutical products must ensure that their products are in line with the highest standards as stipulated by the FDA, regardless of their status of being labeled food or drugs.
