Oxy Lean Elite Proprietary Blend
Also known as: OxyELITE Pro, OEP, OxyELITE Pro Proprietary Blend
Overview
OxyELITE Pro (OEP) was a multi-ingredient dietary supplement marketed for fat loss and energy enhancement. It contained a proprietary blend of ingredients, including caffeine (approximately 100mg per capsule) and Bacopa monnieri, alongside other undisclosed botanical extracts. Classified as a thermogenic weight-loss supplement, OEP gained notoriety due to significant safety concerns rather than proven efficacy. While it contained plant-derived compounds, the exact sources and proportions of many ingredients were not disclosed, making a full chemical identifier impossible. Research into OEP's effects is limited, with no robust human clinical trials demonstrating its efficacy for weight loss or muscle building. Instead, the scientific literature is dominated by case reports detailing severe adverse events, particularly hepatotoxicity.
Benefits
There are no peer-reviewed, randomized controlled trials (RCTs) meeting standard inclusion criteria (e.g., n≥30, proper controls) that demonstrate the efficacy of OxyELITE Pro for weight loss or muscle building. Anecdotal reports suggest an energy boost, which is primarily attributed to the caffeine content. However, these anecdotal accounts are not supported by rigorous clinical evidence. The lack of robust scientific studies means that any claims of weight loss or performance enhancement associated with OEP are unsubstantiated. The available evidence points to significant safety risks rather than any confirmed benefits.
How it works
The proposed mechanisms of action for OxyELITE Pro's components are largely speculative due to its proprietary blend formulation. Caffeine, a known ingredient, acts primarily through adenosine receptor antagonism, leading to increased alertness and perceived energy, with a half-life of approximately 1.7-2.5 hours. Bacopa monnieri is thought to exert cognitive effects through modulation of acetylcholine. For the unidentified components within the proprietary blend, their mechanism of action is largely inferred from the observed adverse event profiles, with some researchers suspecting beta-adrenergic activity, which could contribute to thermogenesis and cardiovascular effects. However, without full disclosure of ingredients, the precise biological pathways and interactions with body systems remain largely unknown and unconfirmed.
Side effects
OxyELITE Pro has a significant and well-documented safety profile, primarily characterized by severe hepatotoxicity. An outbreak in Hawaii identified over 8 cases of acute liver injury, with patients exhibiting ALT levels exceeding 1,000 U/L, strongly associated with OEP use. Cardiovascular side effects, including increased blood pressure and pulse rate, were observed in small phase 1 safety studies. Furthermore, regulatory investigations by the FDA identified undeclared pharmaceutical ingredients, specifically fluoxetine (an SSRI antidepressant), in certain batches of OEP in 2015, posing serious health risks and potential drug interactions, particularly with other SSRIs or MAOIs. Due to these severe risks, OEP is contraindicated in individuals with liver disease, hypertension, or those taking psychiatric medications. The lack of an established safe dose and the high risk of liver injury make its use highly dangerous.
Dosage
The manufacturer's label recommended a dosage of 2-3 capsules per day, which would deliver approximately 200-300mg of caffeine daily. However, due to the significant and well-documented risk of hepatotoxicity and other severe adverse effects, no established safe dose for OxyELITE Pro exists. Regulatory bodies and medical professionals strongly advise against its use. There are no specific timing considerations or different dosages for various purposes that can be recommended safely. The presence of undisclosed ingredients and the documented contamination with pharmaceutical drugs further complicate any attempt to establish a safe or effective dosage. Individuals with pre-existing conditions such as liver disease or hypertension, or those on psychiatric medications, are particularly at risk and should strictly avoid this product.
FAQs
Is OxyELITE Pro effective for weight loss?
No, there is no clinical evidence from robust, peer-reviewed randomized controlled trials to support its effectiveness for weight loss.
Why was OxyELITE Pro recalled?
It was recalled due to multiple reported cases of severe liver injury (hepatotoxicity) and the discovery of undeclared pharmaceutical ingredients like fluoxetine.
Is OxyELITE Pro safe for long-term use?
No, it is contraindicated for any use, especially long-term, due to the high risk of liver damage and other serious adverse effects.
What are the main risks associated with OxyELITE Pro?
The primary risks include severe liver injury (hepatotoxicity), cardiovascular issues like increased blood pressure, and potential adverse drug interactions due to undeclared ingredients.
