NutraBio Has Independent Testing Done To Refute Ryan Garcia’s Claim That Supplements Led To Failed Drug Test

NutraBio claim to have done independent testing to prove Ryan Garcia’s claims wrong.

After Ryan Garcia’s legal team claimed that one of NutraBio’s supplements contained a banned substance and this played a role in his failed drug test – on Friday the company released a statement claiming that, after independent testing, there was no traces of illegal substances.

The product in question being tested was NutraBio’s Super Carb. This is used to aid in recovery during or after workouts. Garcia ha sclaimed that Super Carb was part of his supplementation during training for his fight – and “contaminated ingredients” were to blame for his failed drug test.

So after much controversy, it would seem we have yet another chapter to the saga involving Ryan Garciaand a failed drug test following his fight with Devin Haney.

NutraBio took to Twitter to share it’s latest statement and news of the independent testing:

“NutraBio categorically rejects the reckless claims made by professional boxer Ryan Garcia and his team that the NutraBio SuperCarb product cause Mr. Garcia’s positive test for Ostarine. NutraBio has never manufactured a supplement with Ostarine and has never brought Ostarine into our manufacturing facility for use in any product, ever.”

Garcia defeated Haney by majority decision but retained his belt after Garcia missed weight ahead of the fight.

NutraBio Responds To Ryan Garcia’s Claims

Garcia tested positive for Ostarine and 19-Norandrosterone Metabolite the day before he stepped in the ring with Haney. This is a banned substance that is derived from nandrolone. On May 7, Garcia was cleared for one banned substance but later results revealed that he still tested positive for Ostarine.

NutraBio’s CEO and founder Mark Glazier shared that the company did its own testing following these claims.

“A retain of the SuperCarb in question has been tested for ostarine at ISO 17025 accredited laboratories by Eurofins and BSCG (Banned Substance Control Group), both of which are leading independent third party testing providers. The testing confirmed there was no Ostarine detected in the product.”

Ryan Garcia’s team originally claimed that the boxer was clean but the B sample results detected a trace of Ostarine, which was enough to be considered a positive test.

NutraBio is taking these allegations seriously. 

“Further, the miniscule amount of Ostarine allegedly detected in the open container of SuperCarb doe not explain the amount of Ostarine identified in Ryan Garcia’s urine, which isat 6 ng/ml is 60 times the testing limit.

We take any claims against our company extremely seriously and stand by our process for ensuring the quality, safety, and security of our products.”

The concept of “contaminated supplements” is not uncommon, and certainly these sort of issues do arise. It’s part of the reason why drug testing organizations in sports often provide athletes with a list of supplements that should not be used to avoid failed drug tests.

However, a claim of contaminated ingredients from a high profile figure such a s Ryan Garcia can have damaging effects on a company brand. So it would make sense that a company such as Nutrabio would take great efforts to clear the air and clear their name of any issues with the ingredients in their products.

At the time of this writing, Ryan Garica nor his legal team has responded to the updated statement and claims made by Nutrabio.
