Competition ready

Trusted by the brands you trust
Trusted by the brands you trust
NSF works behind the scenes with nutrition and wellness brands to verify that what’s on the label is what they deliver in the product.
Wellness, certified
When you see the NSF certification mark, you can trust that the nutrition and wellness products you’re using are verified for purity, safety and quality, so you can make product choices with confidence.
Truth in every label
NSF Contents Certified confirms dietary supplement and active nutrition product label accuracy, including identity, potency and purity. Because what’s on the label should be what’s in the product.
More than skin deep
NSF Contents and Claims Certified ensures beauty and personal care products are accurately labeled, with ingredient claims independently verified for truth and accuracy.
Trusted brands trust NSF
From your vitamins to supplements, chances are you already use an NSF certified brand.
Brand logos indicate that one or more products from the brand are NSF certified. Not all products sold by these brands are NSF certified. To verify individual product certification, visit the NSF Certified Products database.
