Ultra Weight Management & Metabolism Booster — Capsules, 120 Count — Supports Healthy Weight Management*
LifeSource Vitamins Ultra Weight Management & Metabolism Booster combines clinically studied actives — including green tea extract (catechins with caffeine), apple cider vinegar, and supportive botanicals — to encourage thermogenesis, support fat oxidation, and help healthy appetite control. Produced in FDA-registered, GMP-certified facilities and 3rd-party tested for identity, potency & purity.*
Research Promise: At Lifesource Vitamins, our commitment is rooted in research and results. Every benefit below is supported by human clinical studies indexed in the National Institutes of Health (NIH) via PubMed, with full texts available in the National Library of Medicine (NLM) PubMed Central (PMC) when available. In addition, we reference reviews from 39 leading health organizations and insights from 20 top global universities to ensure our guidance aligns with credible science.*
Clinically Studied Benefits (with research)
• Thermogenesis & modest weight reduction — Green tea catechins with caffeine were associated with small but significant reductions in body weight/BMI in adults (NIH/PubMed — Hursel R, 2009).
• Energy expenditure & fat oxidation — Green tea extract rich in catechins plus caffeine increased 24-h energy expenditure and fat oxidation versus control (NIH/PubMed — Dulloo AG, 1999).
• Weight management signal (meta-analysis) — Pooled RCT data show catechin-caffeine mixtures yield a modest effect on body weight/BMI in adults (NIH/PubMed — Phung OJ, 2010).
• Vinegar intake & body weight — 12-week randomized trial reported reductions in body weight, BMI, and waist circumference with daily vinegar (NIH/PubMed — Kondo T, 2009).
Additional Studies Showing Promising Benefits*
• Apple cider vinegar (emerging) — Recent human trials report reductions in weight and waist measures; findings remain preliminary and require replication (NIH/PMC — Abou-Khalil R, 2024).
• African mango (Irvingia gabonensis) — Small RCTs show short-term changes in body weight and lipids; overall quality is low-to-moderate; additional robust trials needed (NIH/PubMed — Onakpoya IJ, 2013).
• Green coffee/chlorogenic acids — Human evidence suggests possible modest weight effects; heterogeneity and earlier study limitations warrant caution (NIH/PubMed — Kanchanasurakit S, 2023).
• Resveratrol (mixed) — Trials/meta-analyses show inconsistent effects on anthropometrics; some metabolic markers may improve; weight impact remains uncertain (NIH/PMC — Ríos-Herrera Á, 2022).
University Studies (Promising — Human / Academic Research)
• Green tea research at academic centers — University-affiliated clinical trials contribute to the thermogenic/fat-oxidation signal for catechin-caffeine combinations in adults (NIH/PubMed — Hursel R, 2009; NIH/PubMed — Dulloo AG, 1999).
• Polyphenols & weight-related metrics — Academic meta-research suggests potential benefits under specific conditions; more large, well-controlled RCTs are warranted (NIH/PubMed — Kanchanasurakit S, 2023).
Global Evidence & Authoritative Reviews*
• Green tea for weight loss — Cochrane review: effects are generally small and may not be clinically meaningful; safety acceptable at studied intakes (NIH/PubMed — Jurgens TM, 2012; NIH/PMC — Jurgens TM, 2012).
• Citrus aurantium (p-synephrine) — Overview highlights limited human weight-loss evidence and underscores dose/safety considerations (NIH/PMC — Koncz D, 2022).
• Authoritative summaries — National and academic bodies provide balanced overviews of botanicals for weight management (e.g., fact sheets/monographs; consult individual entries on NIH/NCCIH/ODS where available).
We monitor research from the world’s leading institutions — including Harvard, Johns Hopkins, Mayo Clinic, Cleveland Clinic, Cambridge University, Oxford, Stanford, Yale, MIT, the University of Florida, Oregon State University – Linus Pauling Institute, Tufts, Boston University, Cornell, Columbia, and Ohio State — to ensure our guidance remains aligned with the highest standards of credible science.*
