Top 10 Best NSF Certified Protein Powders Available Today

nsf logo

It’s no secret that muscle gains are made during recovery… and consuming protein after working out is dubbed to be critical for good recovery.

However, you might be surprised to know the ingredients labeled on many protein powders might not actually be accurate. Because protein powder supplements do not require FDA approval for marketing, protein powders may contain different ingredients or quantities than what the label claims. You very well might unknowingly be consuming less protein and more sugar and other artificial sweeteners than what is stated on the product.


That being said, in order to avoid untrustworthy protein powders, it’s important to look for the products that are NSF Certified (either a Contents Tested and Certified Certification or a Certified for Sport Certification). NSF International provides third-party testing specifically for supplements. This organization ensures that the contents of these supplements match what is printed on the label and that there are no unsafe substances in these products.1

By purchasing protein powder that is NSF certified you can be certain that what you are putting in your body is the real deal.

Without further ado, here you can find the 10 best NSF certified protein powders available today.

Founded in 1986, Optimum Nutrition has been helping athletes achieve their fitness goals for over 30 years. Since the company first started, it has valued innovation, quality and ingredient transparency over everything, making it the go-to brand for protein powder among fitness enthusiasts. According to Alpesh Patel, the senior vice president of global marketing for the company, “Optimum Nutrition and its founder recognized early the need for strict quality control”. This focus on quality control explains why Optimum Nutrition is one of the few sports nutrition companies to operate its production facilities. Today Optimum Nutrition’s Gold Standard 100% Whey is undoubtedly one of the most popular protein powders in the industry.2 3
