LifeSource Vitamins Whey Protein Concentrate — Grass-Fed — Double Chocolate Fudge — 6 lb — ~23 g Protein per Scoop — Muscle Growth & Recovery Support*
Premium whey protein concentrate (WPC) from grass-fed dairy to support muscle protein synthesis, post-exercise recovery, and daily strength goals.* Cross-flow micro-filtration at low temperatures preserves native whey fractions and bioactive peptides, while stevia keeps it delicious without added sugars.* Produced in FDA-registered, GMP-certified facilities and 3rd-party lab tested for purity, potency & label accuracy.*
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 guidance aligned with credible science.*
Clinically Studied Benefits (with research)
• Post-exercise MPS — Whey stimulates muscle protein synthesis more than several comparators in trained adults. (NIH/PubMed — Tang, 2009)
• Strength & lean mass (with training) — Protein supplementation increases fat-free mass in RCTs. (NIH/PubMed — Morton, 2018 (meta-analysis))
• Recovery & adaptations — Expert position stand supports protein (incl. whey) for performance and reduced damage. (NIH/PubMed — Kerksick, 2017)
• Leucine-rich trigger — Rapidly digested whey with higher leucine content supports acute MPS signaling. (NIH/PubMed — Pennings, 2011)
• Strength in trained cohorts — Protein + resistance training improves strength outcomes. (NIH/PubMed — Cermak, 2012 (meta-analysis))
• Body composition during dieting — Higher-protein strategies help preserve lean mass while cutting calories. (PMC — 2018 review)
• Satiety & appetite — Whey beverages modulate appetite and postprandial responses. (PMC — 2019 review)
• Glycemic response (within normal range) — Pre-meal whey can blunt post-meal glucose/insulin excursions. (NIH/PubMed — 2018)
• Blood pressure (within normal range) — Meta-analyses link whey peptides to modest BP reductions. (NIH/PubMed — 2017)
• Antioxidant defenses — Whey increased glutathione-related capacity in humans. (NIH/PubMed — 2008)
Additional / Promising Evidence*
• Older adults* — Whey around training can aid composition/strength metrics. (NIH/PubMed — 2019)
• Endurance recovery* — Protein supports recovery markers post-endurance sessions. (NIH/PubMed — 2014)
• Body composition* — Protein during resistance training shows favorable FFM changes. (PMC — 2019)
• Weight management* — Meta-analytic data suggest improvements in composition indicators. (NIH/PubMed — 2022)
• Microbiota/metabolites* — Protein supplements can influence gut microbial/metabolic markers. (PMC — 2020)
• Female athletes* — Protein timing/quality considerations in active women. (NIH/PubMed — 2018)
University / Academic Context*
• McMaster University & University of Texas groups have repeatedly shown whey’s rapid digestion/leucine content drives robust MPS responses in trained adults. (See Tang 2009; Morton 2018)
Global Evidence & Authoritative Reviews*
• International Society of Sports Nutrition (ISSN) — Position stand supports protein (incl. whey) for athletes. (Kerksick 2017)
• Systematic reviews & meta-analyses — Multiple NIH-indexed analyses substantiate lean-mass and performance benefits with training (Morton 2018; Cermak 2012).
We monitor research from leading institutions — Harvard Univ, Johns Hopkins Univ, Mayo Clinic, Cleveland Clinic, Cambridge Univ, Oxford Univ, Stanford Univ, Yale Univ, Tufts Univ, Univ of Florida, Oregon State Univ (Linus Pauling Institute), Columbia Univ, Cornell Univ, and many more — to keep our guidance aligned with credible science.*
