In general, the quality standards expressed in GMP certification assures the consumer that:
- Manufacturer supplied information about the product is true and accurate
- The label reflects the actual ingredients
- The product is free from contaminants and impurities and is safe to consume
Customers also look for information to determine:
- If the ingredients are considered “natural” and not synthetic. Many consumers become deeply educated about ingredients. They look for understandable words for ingredients they might find in their own kitchens, i.e. organic information and the absence of artificial flavors, sweeteners, preservatives, and other additives.
- If dietary supplements work. The best evidence of the efficacy of nutritional supplements can be found in scientific research and clinical trials on the ingredients. Reputable, quality manufacturers will reference their research on their websites and in their product literature.
- If the ingredients in the supplements will have an adverse effect or interact with their prescribed medications. Some ingredients in nutritional supplements will interact with pharmaceutical drugs or other nutritional supplements ingredients in an adverse way. For example, people taking prescribed blood-thinning medication should avoid taking supplements with Vitamin K since Vitamin K interferes with the medication and increases the risk of blood clots; or people who are taking anti-depressants should avoid consuming L-Tryptophan Peptide for relaxation and sleep. Warnings should always be stated on the label.
- If the product was produced in keeping with sustainable and humane practices. Many customers prefer products that avoid animal testing, are produced with high animal welfare standards and environmental integrity, from certified organic and non-GMO certified to recyclable or compostable packaging. Manufacturers provide information on their participation in sustainable practices on their product packages, in their literature, and on their websites.
