Are Your Supplements Safe? We’ve Got You Covered.
If you take dietary supplements, you’re probably seeking to improve your overall health. Indeed, people’s health concerns are driving the current demand for dietary supplements, from vital vitamins, minerals and nutrients to amino acids, botanical extracts and enzymes. The global dietary supplement market was valued at $159.2 billion in 2021, and it’s expected to reach a value of $227.4 billion by 2028, at a compound annual growth rate of more than 7.9% over the forecast period (2022-2028), according to a recent report.
But have you considered what you’re putting into your body?
At NSF, our experts take supplement safety seriously, from testing and reviewing products for contaminants or banned substances to inspecting the factories where they’re produced.
How your supplement is made is just as important as the supplement itself. GMP stands for “Good Manufacturing Practices,” which are rules manufacturers follow to help ensure that the products you use are produced to the strictest quality standards. In the United States, the FDA oversees these GMP rules for dietary supplement manufacturers.
GMP inspections cover all areas of supplement production, including:
- Facility cleanliness
- Ingredient storage
- Allergen controls
The good news is: The certifications are here to protect you. Supplements are a great option for those who are interested in a healthy lifestyle — if they follow instructions and consult with a clinician or their doctor first.
Supplement manufacturers must document their procedures at every step of the process; some supplement producers go the extra mile and have their facilities and processes certified. That’s where NSF/ANSI 455-2 certification comes in.
How It Works
For a company to earn NSF/ANSI 455-2 GMP certification, it must be audited annually by an independent third-party certification body, like NSF. The review includes an audit of the company’s operations to make sure they’re following all the rules to protect the quality and safety of the products you buy.
But if you don’t know whether the supplements you take were produced in a GMP-certified facility, it’s easy to find out.
We’ve included all the facilities that have earned NSF GMP certification in our certification listings database. You can also look for the NSF GMP certification mark on your favorite vitamin company’s website or contact them and ask if they’re NSF certified for GMPs.
