Fact check: What is the supplement that RFK jr. recommends and Donald Trump has backed to help lose weight and has been used by the military to drop weight fast?

1. Summary of the results

Based on the analyses provided, no specific supplement recommended by both RFK Jr. and Donald Trump for weight loss has been identified. The sources primarily discuss prescription weight-loss medications rather than supplements. The analyses reveal that RFK Jr. has shifted his position on weight-loss drugs, now saying they "have a place" ^[1], while the Trump Administration has decided not to cover anti-obesity drugs under Medicare and Medicaid in 2026 ^[2].

The sources mention GLP-1 agonist medications such as Ozempic, Wegovy, Mounjaro, and Zepbound as weight-loss treatments ^{[1] [3]}, but these are prescription drugs, not supplements. Dr. Oz, a Trump nominee, has promoted these GLP-1 medications ^[3], but this does not constitute a joint recommendation from RFK Jr. and Trump for a specific supplement.

Regarding military use, the analyses show that 74% of service members use dietary supplements, with 44% using combination products and 42% using proteins/amino acids ^[4]. However, a concerning study found that 25 out of 30 weight loss supplements marketed with military discounts had inaccurate labels, with 24 products being misbranded and 10 containing substances prohibited for military use ^[5].

2. Missing context/alternative viewpoints

The original question assumes the existence of a specific supplement jointly endorsed by RFK Jr. and Trump, but this premise is not supported by the available evidence. The analyses reveal several important contextual factors:

• RFK Jr.'s evolving stance: He has moved from opposition to acceptance of certain weight-loss treatments, now acknowledging they "have a place" ^[1]
• Policy contradictions: While there may be individual endorsements of weight-loss treatments, the Trump Administration's policy actively excludes coverage of anti-obesity drugs from government healthcare programs ^[2]
• Supplement industry interests: RFK Jr.'s support for the "Make America Healthy Again" agenda targets alleged corruption in health regulatory agencies, which could benefit supplement manufacturers who see a chance to "cash in" ^[6]
• Military supplement risks: The military context reveals significant safety concerns, with combination weight-loss products showing higher adverse event rates ^[4] and widespread mislabeling in products marketed to service members ^[5]

3. Potential misinformation/bias in the original statement

The original question contains several unsubstantiated assumptions:

• False premise: It assumes a specific supplement exists that both RFK Jr. recommends and Trump has backed, which is not supported by the evidence ^{[1] [3] [2]}
• Conflation of treatments: The question may be confusing prescription weight-loss medications (like GLP-1 agonists) with dietary supplements, which are different categories of products with different regulatory frameworks
• Military endorsement claim: While military personnel do use supplements extensively ^[4], there is no evidence of official military endorsement of a specific weight-loss supplement, and research actually highlights significant safety concerns with weight-loss supplements marketed to military personnel ^[5]

The question appears to be seeking validation for a claim that lacks factual foundation based on the available analyses, potentially perpetuating misinformation about celebrity endorsements and military usage of unspecified weight-loss products.
