Ensuring Quality of Dietary Supplements
HealthPricer.com will help you ensure that the supplements you purchase are of the highest quality. The food supplement industry is regulated by two types of agencies.
- The Food and Drug Administration (FDA) strictly regulates health claims made about all dietary supplements and the labels on them in the United States. An FDA Certification does not evaluate for, or regulate, either quality or efficacy of supplements.
- Third Party Certification Bodies have developed strict criteria for standards regulation which evaluate and authenticate the quality of a supplement, its ingredients, dosage levels, label claims and the manufacturing facilities themselves. Organizations such as the United States Pharmacopoeia (USP), the Natural Nutritional Foods Association (NNFA), and NSF International have each developed strict manufacturing standards that help to ensure that the consumer is getting a good quality, effective product.
Manufacturers and distributors have supported these top certification bodies in their efforts to promote quality, efficacy and maintenance of the highest product standards available in the market. The supplement industry is voluntarily working to certify their products in an effort to help consumers make informed and educated decisions.
In an effort to alleviate confusion about certification and regulation of dietary supplements, HealthPricer.com identifies products that have been awarded these valuable certifications with their corresponding seal of approval.
Search for your favorite supplement and let HealthPricer.com identify the manufacturers, products or ingredients that have been evaluated, helping you select products of the highest quality.
