Experience More Vitality

Sometimes, when life gets in the way, our enthusiasm level can suffer as a result. If you are feeling less than energetic, you will likely have a less effective workout, which can hinder your progress toward your goal. NSF Certified for Sport® supplements from Thorne are safer and more effective way to obtain the nutritional support you need to help maintain or regain your vitality.

Thorne’s NSF Certified for Sport® products are formulated to give you the boost you need to achieve your exercise goals.

Replenish Lost Electrolytes

Workouts disrupt the natural balance of vitamins and minerals in the body. That’s why some of the best supplements for performance concentrate on replenishing lost electrolytes.

Electrolytes are lost through sweat, especially in hot, humid weather. These minerals, such as magnesium, calcium, sodium, and potassium, enable your body to function. Your body aims to maintain an optimal balance of electrolytes, so give it the help it needs with an electrolyte supplement.

Many individuals turn to sports drinks to replenish lost electrolytes, but these drinks often aren’t a healthy choice. Make the switch from sports drinks with high sugar content and heavy caffeine levels to Thorne’s Catalyte, an electrolyte supplement for sports performance.

Gain a Protein Boost

Protein is the building block of strong muscles and a healthy body. This macronutrient is essential for your stamina, strength, and energy levels. Active individuals should be looking to take in 1.2-2.0 grams of protein per kilogram of body weight, depending on your personal health and fitness goals.

High-performance athletes require even more protein to ensure their bodies have the building blocks for strength, muscle repair, and effective recovery from a workout. However, getting enough protein through diet alone can be a challenge. That’s where a protein powder supplement like Thorne’s Whey Protein can fill the gap.

The best supplements for performance should give you the foundation you need to up your game.

Regroup and Recover
The best performance supplements don't just support your performance at the gym - they should also continue to work for you outside the gym. Some of the essential nutrients in Thorne's supplements that can aid in recovery include amino acids, omega-3 fatty acids, and multi-vitamin supplements. Get the most out of each gym session by giving yourself what you need to recover fully. Take care of your body with Thorne's science-backed supplements today.

We invest in the certification you must earn — NSF Certified for Sport®. Thorne
has an NSF Certified facility for Good Manufacturing Practices in which we
manufacture 20+ NSF Certified for Sport® products, which gives athletes
complete confidence in Thorne supplements.
What does NSF Certified for Sport® mean?

The NSF Certified for Sport® program ensures that your supplements have been tested to ensure they do not contain any banned substances. No athlete should risk consuming a banned substance.

NSF certification is a rigorous supplement testing process, inspecting each batch of product after it’s manufactured but before it’s released for sale.

The NSF Certified for Sport® program validates that a nutritional supplement contains none of the 300+ substances banned by major athletic organizations.

The NSF Certified for Sport® program verifies that the contents of the product match what is on the product’s label. Transparency is a crucial aspect of the NSF Certified for Sport® program.

Before a supplement manufacturer can participate in NSF’s Certified for Sport® program, the manufacturer must first receive NSF’s certification as a Current Good Manufacturing Practices facility and be audited every year by NSF to maintain that certification.

NSF’s strict testing regimen allows you to confidently add Thorne supplements to your routine, knowing you're giving your body the best. The products in our athletic performance suite have all received the NSF Certified for Sport® status, meaning they have met the most stringent quality standards for the professional and recreational athlete alike.

Why professional
athletes care
Pros love Thorne’s NSF Certified for Sport® product line for its
testing to ensure the absence of more than 300+ banned
substances. This NSF certification offers professional athletes
peace of mind knowing that nothing on the extensive banned
substance list will show up on a drug test.
Why you will,
too
Although you might not be tested for the presence in your
blood of 300+ banned substances, knowing what you are
putting into your body is essential. In addition to NSF certification,
Thorne conducts four rounds of testing,
ensuring that the final product contains only what you
need for optimal body function.
