This article will take a closer look at Klean Athlete, including what it is, what products it offers, and who it may be a good fit for.

Klean Athlete is a supplement company that was founded by athletes for athletes.

Klean Athlete offers a range of products formulated specifically for athletes, including protein powders, pre- and post-workout blends, and other products meant to enhance performance.

Because all supplements are third-party tested and NSF Certified for Sport, Klean Athlete’s products may be worth the investment for competitive athletes seeking a safe and effective option to enhance exercise performance.

However, Klean Athlete products are somewhat expensive and may not be the best fit for budget-conscious consumers.

Because Klean Athlete is focused mostly on sports supplements, people looking to improve certain aspects of health or address specific health-related concerns may want to opt for other brands with a more varied product selection.

Additionally, certain Klean Athlete supplements may not be suitable for people following vegan, vegetarian, or ketogenic diets.

Klean Athlete offers over 30 supplements, most of which are geared toward athletes. All of them are NSF Certified for Sport.

Here are a few of the brand’s best supplements.

Klean Athlete is a reputable supplement manufacturer that specializes in producing high quality products for athletes.

According to their website, the brand is trusted by over 100 colleges and 200 professional sports teams throughout the United States and Canada. Klean Athlete is also a partner of the Collegiate and Professional Sports Dietitians Association.

At the time of publication, Klean Athlete isn’t currently registered with the Better Business Bureau.

However, most of their products are highly rated by customers on third-party websites.

For example, their Klean Multivitamin has over 1,000 reviews on Amazon and an average rating of 4.5 out of 5 stars.

Similarly, Klean Creatine currently has an average rating of 4.6 out of 5 stars on Amazon, which is based on over 900 customer reviews.

Positive reviews mention that the supplements are effective and easy to use. A few also state that the capsules are easy to swallow and the powders mix well when added to shakes and smoothies.

On the other hand, less favorable reviews note issues with the taste, price, or packaging of products.

Compared with other supplement brands, Klean Athlete’s products are relatively expensive.

For example, their Klean Creatine costs around $0.53 per serving. For comparison, Thorne‘s creatine supplement costs around $0.44 per serving, while a creatine supplement from NOW Foods ranges from $0.32 to $0.42, depending on the size you select.

Similarly, Klean Zinc is priced at nearly $0.19 per serving, which is significantly higher than the zinc supplements from NOW Foods, which are around $0.08 per serving.

That being said, Klean Athlete regularly offers promos on their website, including free products when you spend a certain amount, discount codes when you sign up, and free shipping for orders over $40.

Klean Athlete supplements feature high quality, clinically studied ingredients.

In fact, many of the ingredients in the supplements that they offer have been shown to enhance sports performance.

For instance, studies show that creatine could help increase muscle mass and boost exercise capacity (5).

Branched chain amino acids (BCAAs), which are found in Klean BCAA + Peak ATP, have also been shown to improve recovery and muscle function after high intensity resistance training (9).

Plus, the brand uses highly effective forms of nutrients in other products, such as vitamin D3, which is found in their Klean-D and Klean Multivitamin supplements (10).

Klean Athlete products are thoroughly tested through in-house and independent laboratories to ensure that they’re safe and free of harmful contaminants.

For the most part, the ingredients used in Klean Athlete supplements — such as creatine, collagen, and whey protein — are also safe and associated with very few side effects (11, 12, 13).

However, keep in mind that certain supplements may not be suitable for everyone.

For example, whey protein shouldn’t be used by those with an allergy to cow’s milk (14).

Additionally, there is limited research on the safety of melatonin — a key ingredient in their Klean Melatonin supplement — for people who are pregnant or breastfeeding (15).

Therefore, it’s best to talk with a doctor before adding any Klean Athlete supplements to your routine, especially if you have any underlying health conditions or are taking medications.

In addition to Klean Athlete, there are several similar brands that offer sports supplements for athletes. Here’s how the brand compares.
