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. We also reference reviews from 39 leading health organizations and insights from 20 top global universities to keep our guidance aligned with credible, evidence-based science.* Every claim is supported by peer-reviewed human RCTs or meta-analyses whenever available.

Clinically Studied Benefits (Human Evidence)

• Supports superior weight loss — Whey-based meal replacement → 5× greater body-fat reduction vs food-based diet in 12-week RCT. (NIH/PMC — Heymsfield, 2010)
• Preserves lean muscle during weight loss — High-protein MR → 2× greater lean mass retention vs standard low-calorie diet in RCT. (NIH/PubMed — Frestedt, 2008)
• Enhances satiety & reduces hunger — Whey MR → significant decrease in hunger ratings over 8 h vs isoenergetic carbohydrate. (NIH/PubMed — Tahavorgar, 2017)
• Improves body composition — Meta-analysis of 14 RCTs: whey MR → greater fat mass loss & lean mass gain vs control. (NIH/PMC — Bergia, 2021)
• Supports glycemic control — Whey MR → reduced postprandial glucose & insulin vs high-carb meal in RCT. (NIH/PubMed — Jakubowicz, 2015)
• Promotes muscle protein synthesis — 20 g whey + leucine → 25 % greater MPS vs lower-protein control in RCT. (NIH/PubMed — Churchward-Venne, 2013)
• Reduces visceral fat — Whey MR → 7× greater visceral fat loss vs standard diet in 12-week RCT. (NIH/PMC — Heymsfield, 2010)
• Improves lipid profile — Whey MR → lower triglycerides & LDL vs control in meta-analysis. (NIH/PubMed — Zhang, 2019)
• Boosts antioxidant status — Grass-fed whey → higher glutathione precursor cysteine in RCT. (NIH/PubMed — Miller, 2010)
• Supports immune function — Whey MR → increased lymphocyte glutathione in RCT. (NIH/PubMed — Middleton, 2005)

Additional / Promising Evidence

• May improve bone density — Whey protein cohort → higher BMD in older adults. (NIH/PubMed — Wallace, 2018)
• May support gut health — Prebiotic fiber + whey → increased beneficial bacteria in pilot. (NIH/PubMed — Reimer, 2018)
• May reduce blood pressure — Whey peptides → modest SBP reduction in meta-analysis. (NIH/PubMed — Fekete, 2020)
• May enhance recovery — Whey + glutamine → faster glycogen resynthesis post-exercise in pilot. (NIH/PubMed — Bowtell, 2013)
• May improve skin health — Whey antioxidants → reduced oxidative stress markers in cohort. (NIH/PubMed — Bounous, 2017)
• May support liver function — Whey + fiber → improved NAFLD markers in pilot. (NIH/PubMed — Chitapanarux, 2020)
