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)
• Supports modest reductions in body fat mass* — Meta-analysis of RCTs reports small but significant fat-mass loss with ~3.2 g/day CLA over ~6 months. (NIH/PubMed — Whigham LD, 2007)
• Helps improve body composition in some populations* — Trials note fat-mass reduction and lean-mass preservation under controlled conditions. (NIH/PubMed — Riserus U, 2001)
• Weight-maintenance support* — CLA supplementation helped limit seasonal or long-term fat gain in certain studies. (NIH/PubMed — Blankson H, 2000; NIH/PubMed — Gaullier JM, 2005)
• Lean-mass retention during weight programs* — Some trials found better fat-free mass preservation. (NIH/PubMed — Thom E, 2001)
• Abdominal fat outcomes* — 12-week RCT reported decreases in fat mass and waist-to-hip ratio. (NIH/PubMed — Chen SC, 2012)
• Hormonal marker changes* — CLA supplementation reduced circulating leptin in overweight adults. (NIH/PubMed — Steck S, 2007)
• Metabolic effects are mixed* — Some studies report changes in insulin sensitivity; findings vary by isomer and population. (NIH/PubMed — Riserus U, 2002) (NIH-indexed reviews)
• Overall tolerability in trials* — Review notes CLA generally well-tolerated across 6–12 months. (NIH/PubMed — 2012 Review) (NIH-indexed reviews)
Additional / Promising Evidence*
• Exercise synergy* — Training plus CLA has shown added body-composition benefits in some studies. (NIH/PubMed — Colakoglu M, 2006)
• Inflammatory marker modulation* — Trials report effects on CRP and cytokines (direction varies by isomer/dose). (NIH/PubMed — Moloney F, 2004) (NIH-indexed reviews)
• Oxidative-stress pathways (mechanistic)* — Reviews describe potential antioxidant signaling roles. (NIH/PubMed — 2010 Review) (NIH-indexed reviews)
• Immune-marker effects (overview)* — Evidence summaries describe CLA’s influence on immune responses. (NIH/PubMed — 2019 Review) (NIH-indexed reviews)
• Cardiometabolic endpoints (mixed)* — Studies report variable effects on lipids and insulin function. (NIH/PubMed — Raff M, 2008) (NIH-indexed reviews)
• Bone-related findings (preclinical/human exploratory)* — Early data suggest possible effects on bone markers. (NIH/PubMed — Watkins BA, 2009)
University / Academic Context*
• Isomer-specific outcomes* — t10,c12 vs c9,t11 CLA display different metabolic effects in academic reviews. (NIH-indexed reviews) (Evidence — Harvard, 2024)
• Dose & duration considerations* — Analyses discuss small effect sizes and need for ≥6 months for changes. (NIH/PubMed — Whigham LD, 2007)
• Lean-mass vs fat-mass tradeoffs* — University-affiliated trials report context-dependent results. (NIH/PubMed — Riserus U, 2001)
Global Evidence & Authoritative Reviews*
• Systematic reviews & guidance — Summaries note small average effects on fat mass with mixed metabolic findings; emphasize lifestyle pairing. (NIH/PubMed — 2012 Review) (NIH-indexed reviews)
• Clinical context — Evidence reviews from university nutrition programs and public health groups recommend prudent use and monitoring. (Evidence — Cochrane/Academic, 2012–2020)
We monitor research from leading institutions — Harvard, Johns Hopkins, Mayo Clinic, Cleveland Clinic, Cambridge, Oxford, Stanford, Yale, Tufts, University of Florida, Oregon State University – Linus Pauling Institute, Columbia, Cornell, and Ohio State — to keep our guidance aligned with credible science.*
