Whey Protein Dual Blend - Isolate & Concentrate - Chocolate 2 lbs.

Whey Protein Dual Blend Isolate & Concentrate — Chocolate — 2 lbs — Optimal Muscle Support*

LifeSource Vitamins Whey Protein Dual Blend pairs fast-absorbing whey isolate with sustained-release whey concentrate to deliver both an immediate and extended stream of essential amino acids.* Each 1-scoop serving supplies ~24 g protein with ~5 g BCAAs (≈2.5 g leucine) and ~420 mg L-glutamine, supporting muscle growth, workout recovery, and everyday strength.* Crafted in FDA-registered, GMP-certified facilities and 3rd-party tested for purity, potency & label accuracy.*

• Builds muscle size & strength with training — Protein supplementation improves RET gains; diminishing returns beyond ~1.6 g/kg/day. (NIH/PubMed — Morton 2018)

• Elevates post-exercise MPS in older adults — Leucine-enriched whey increased postprandial MPS. (NIH/PubMed — Luiking 2014)

• Leucine dose matters — Human data: leucine dose predicts MPS responses (no single threshold). (PMC — Wilkinson 2023)

• Supports exercise recovery — RCTs show protein aids muscle-damage/inflammation & DOMS markers after exercise. (NIH/PubMed — Nieman 2020)

• Improves outcomes in sarcopenia — Meta-analyses: whey + RET increases strength & skeletal muscle in older adults. (NIH/PubMed — Cuyul-Vásquez 2023; NIH/PubMed — Li 2024)

• Maintains gains after detraining — Leucine-enriched whey + RET preserved improvements 24-weeks post-training vs training alone. (NIH/PubMed — Mori 2022)

• Rapid digestion → robust anabolic response — Whey’s fast kinetics & high leucine content support superior acute MPS vs slower proteins. (PMC — Breen & Phillips 2011)

• Blood-pressure support — Whey intake reduced systolic BP in meta-analysis. (NIH/PubMed — Vajdi 2023; PMC — Yang 2019)

• Glutathione (antioxidant) support — Human trials show whey can elevate glutathione markers. (NIH/PubMed — Zavorsky 2007; NIH/PubMed — Micke 2001)

• Facilitates recovery & adaptations — Narrative + experimental data support post-exercise benefits. (PMC — Cintineo 2018)

• Protein + RET synergy — Adding protein to training improves mass/strength/function vs training alone. (NIH/PubMed — Hou 2019; PMC — Nunes 2022)

• Real-world dosing guidance — Long-term protein (±exercise) modulates basal/postprandial MPS in older adults. (NIH/PubMed — Bülow 2023)

• Body-composition support — Evidence for body weight/fat mass reductions with whey in overweight/obese. (PMC — Yang 2019)

• Clinical-context immune & inflammatory markers — Improvements reported in select trials (context-specific). (NIH/PubMed — Bumrungpert 2018)

• Timing after exercise — Reviews indicate whey post-workout supports recovery via increased synthesis. (PMC — Kim 2017)

• Protein type comparisons — Trained females: whey vs casein both effective across 8 weeks (no difference in performance). (PMC — Wilborn 2013)

• Age-related anabolism — Academic review: variables regulating anabolic resistance and role of protein quality (whey, leucine). (PMC — Deane 2024)

• Protein intake & training meta-overviews — University-led syntheses confirm lean-mass benefits with added protein during RET. (PMC — Nunes 2022)

• Dietary protein & RET guidance — Additional protein supports training-induced increases in lean mass/strength. (NIH/PubMed — Morton 2018; PMC — Nunes 2022)

• Blood pressure & lipids — Reviews suggest whey may lower SBP and improve select cardiometabolic markers. (NIH/PubMed — Vajdi 2023)

• MPS mechanisms — Whey’s rapid digestion/leucine advantage vs slower proteins. (PMC — Breen & Phillips 2011)

Whey Isolate — typically ~90% protein with lower lactose/fat. It empties from the stomach and appears in blood amino acids rapidly, helping trigger a strong, quick rise in muscle protein synthesis—great immediately post-workout. (PMC — Breen & Phillips 2011)

Whey Concentrate — usually ~70–80% protein and retains more native milk fractions. Slightly more lactose/fat can slow digestion a bit, extending amino acid availability—useful between meals or when you want steadier release.*

Why a Dual Blend? The blend provides a rapid “spark” (isolate) plus a steadier “sustain” (concentrate) to cover multiple windows of recovery and satiety across the day.*

• Dual-phase protein: fast + sustained delivery*

• Supports muscle growth & post-workout recovery*

• ~5 g BCAAs (≈2.5 g leucine) per scoop*

• Includes naturally occurring/added L-glutamine (~420 mg)*

• 3rd-party lab tested for identity, potency & purity

Adults: Mix 1 level scoop (~42 g) with 8–10 oz cold water or milk. Use post-workout for rapid recovery or between meals for steady protein support. Contains milk.

Whey Protein Isolate — fast, leucine-rich protein that rapidly elevates plasma AAs to stimulate MPS. (PMC — Breen & Phillips 2011)
Whey Protein Concentrate — complements isolate with a steadier amino acid release for prolonged support.*
BCAAs (Leucine, Isoleucine, Valine) — ~5 g per scoop; leucine is a key driver of MPS. (PMC — Wilkinson 2023)
