What Does NSF Certified for Sport® Mean for Me?

As an athlete, especially a competing athlete, having to maintain peak health alongside intensive training schedules can be incredibly demanding and time-consuming. To perform at your best, you need to make sure your body is being fuelled correctly.

Trying to include all the nutrients you need within just your diet alone is not always easy, especially when leading such a busy and active lifestyle, which is why many athletes tend to lean on supplements to help fill the gaps.

You should never compromise on product quality or safety as an athlete, but can you always trust in the sports products that you’re purchasing online? Well, if they’re NSF Certified for Sport® like Klean Athlete supplements, you can.

What is NSF Certified for Sport®?

The NSF Certified for Sport® programme is designed to:

  • Protect against the adulteration of products
  • Verify all label claims against product contents
  • Identify any athletic‐banned substances in both the ingredients and final products.

To ensure continued safety and maintaining of certification, no changes can be made by manufacturers to formulations or suppliers without full evaluation and approval from NSF.

When it comes to safety and quality certifications for dietary supplements, NSF International is considered the leading standard. The National Sanitation Foundation (NSF) was founded in 1944 as a non‐profit, with the main aim to develop standards for both food sanitation and safety. It is also the leading accredited third‐party certifier of functional foods, dietary supplement raw ingredients, and dietary supplements.

For supplements to be certified, they must go through rigorous testing to meet high industry standards, which includes an extensive evaluation of the manufacturing process and comprehensive lab testing to ensure no hidden or contaminated ingredients are added to products.
