About ConsumerLab supplement certification

Established in 1999, ConsumerLab has grown to become the world’s leading provider of independent test results, supplement certification seals, and supplement information to help healthcare professionals and consumers make informed decisions when it comes to selecting health and nutrition products. Various books, media, and even professional conferences have featured CL’s studies and results, adding to its prestige in the supplement industry. For the past 25 years, the company has successfully tested over 7,000 products, representing more than 1,000 different brands and almost all types of popular supplements for children, adults, and pets. possesses the most stringent testing criteria among third-party organizations that evaluate the quality of dietary supplements. Moreover, it stands out as the sole certification body that openly shares its testing methodologies and standards for quality assurance.

In order to attain ConsumerLab certification, supplements have to undergo rigorous testing to ensure they adhere to the claimed quality standards and ingredient levels stated on the label. Additionally, they must be free from contaminants and exhibit proper disintegration for effective utilization by the body. Not only is compliance with these criteria obligatory to earn the ConsumerLab Approved Quality Seal, but manufacturers cannot directly provide samples of their products. Instead, ConsumerLab acquires the samples through purchase on the open market at a random time of the year to avoid sampling bias. Products are also subject to testing every twelve months.


What is NuBest tested for?

Jargons aside, what exactly does NuBest’s joining the ranks of ConsumerLab-certified supplements mean? This verifies that NuBest Tall 10+ has been tested for and passed all of the following criteria:

  • Identity: The product meets recognized standards of identity and the level of quality claimed on the label.
  • Strength (quantity): The product contains the amounts of ingredients claimed on the label.
  • Purity: The product is free of specified contaminants.
  • Disintegration: The product breaks apart properly so that it may be used by the body.

Following the initial certification testing, the products undergo random annual assessments to ensure they’re being held to consistent standards on an ongoing basis.


Why testing?

Although NuBest consistently adheres to all FDA regulations and GMP certifications regarding dietary supplements, mere compliance with governmental standards is not enough. We aim to do more than that because we fully understand how important safety plays a role in selecting health and nutrition products.

In particular, numerous growth supplement brands have flocked the market in recent years but the majority of which come from ambiguous origins and carry questionable ingredients. This has stirred significant concern among consumers, especially with burning questions like “Is NuBest Tall safe?”, “What are NuBest Tall side effects?”, or “Is NuBest Tall FDA-approved?” constantly emerging on the Internet. That’s why we have taken proactive steps to ensure the safety and quality of our products.

The prestigious Seal of Approval reaffirms our unwavering commitment to providing you with the highest standard of quality and safety in our supplements. Starting with our bestseller NuBest Tall 10+, we strive to have more products tested in the future so customers can have the ease of mind knowing they are giving their bodies only the best that nature has to offer.
