Dietary supplements, functional foods, homeopathic remedies and topically-applied cosmeceuticals make up the nutritional genre called Nutraceuticals. These products are formulated to provide consumers with specific doses, or strength ranges, of vitamins, minerals, proteins, lipids and herbal botanicals. Manufacturers are bound to adhere to Good Manufacturing Practices (GMP) and follow quality control procedures, similar to those used for consumer products belonging to food, cosmetic and pharmaceutical categories. Tracked batches (i.e., lots) of ingredients are blended with inert excipients to produce tablets, capsules, softgels, powders, liquids, creams or gels. Controlled stability testing involves accelerated aging procedures similar to those used for pharmaceuticals or medical device products. Many products feature concentrated marker compounds, or claim to be natural or organic. Based on the ingredient combinations used, benefit claims often appear on packaging to help influence consumer purchasing decisions. Product benefit claims can result from repeatable, well-established scientific knowledge (e.g., Calcium prevents osteoporosis) or inferred advantages based on more experimental studies; therefore bio availability and efficacy validation studies involving actual clinical trials are not always practical. However nutraceutical manufacturers should perform physical inspections to verify that random sample analysis consistently meet established specifications such as weight, color, consistency, and dissolution time. QC best practices may include obtaining lot-specific ingredient certifications from raw material suppliers. Nutraceuticals, because ingested, are manufactured and QC-checked as carefully as foods. The products featured here were selected to help your purchasing efforts: cleanrooms and facility equipment to minimize contaminants; controlled chambers for testing and storage; and lab instruments to verify proper formulation and quality.
