Benefits

Sports Performance and Recovery

Combined formulation supports athletic performance markers and recovery from training. Multi-ingredient approach addresses multiple performance pathways.

Muscle Preservation / Anti-Catabolism

Leucine triggers mTOR/protein synthesis; carnitine supports fatty acid metabolism — combined helps preserve muscle during training stress and caloric restriction.

Carnipure L-Carnitine Component

Lonza's premium L-carnitine ingredient — supports fatty acid oxidation, exercise recovery, and reduced muscle soreness.

Vegan-Source Leucine

Leucine is the most anabolic BCAA; vegan source distinguishes from typical animal-derived leucine; appeals to plant-based athletes.

Standalone or Smoothie/Drink Mix

Available as standalone supplement or for blending into protein drinks/smoothies — versatile use.

Mechanism of action

1

Leucine mTOR Activation

Leucine triggers mTOR signaling — initiates muscle protein synthesis; key anabolic signal for training adaptation.

2

L-Carnitine Fatty Acid Oxidation

L-carnitine transports fatty acids into mitochondria for energy production — supports endurance and reduces muscle damage from intense exercise.

3

Reduced Tissue Damage and Soreness

Carnipure shown to reduce markers of exercise-induced muscle damage and soreness.

4

Combined Formulation Synergy

Multi-ingredient approach addresses multiple performance pathways simultaneously vs single-ingredient supplements.

About this ingredient

About the active ingredient

MUSCLEGUARD™ is a PROPRIETARY 4-INGREDIENT SPORTS PERFORMANCE BLEND developed by LONZA.

KEY COMPONENTS: (1) CARNIPURE® L-CARNITINE — Lonza's premium L-carnitine for fatty acid oxidation and exercise recovery; (2) VEGAN-SOURCE LEUCINE — most anabolic BCAA; vegan distinguishes from typical animal-derived; (3) Additional supporting ingredients per proprietary blend specification.

KEY DISTINCTIONS: (1) PROPRIETARY MULTI-INGREDIENT FORMULATION; (2) VEGAN-SOURCE LEUCINE; (3) Carnipure premium L-carnitine; (4) Standalone or smoothie/drink mix versatile use; (5) Lonza pharmaceutical-grade quality.

EVIDENCE-BASED USES: (1) Sports performance and recovery; (2) Muscle preservation/anti-catabolism; (3) Training adaptation support; (4) Complete sports nutrition adjunct.

CRITICAL CAUTIONS: (1) ATHLETIC FOCUS — designed for athletic populations with elevated nutrient needs; benefits in non-athletes more limited; (2) DOSE — per Lonza product specification; (3) TIMING — typical use around training; per product instructions; (4) PREGNANCY/LACTATION — not designed for these uses; consult; (5) MUSCLEGUARD vs SEPARATE INGREDIENTS — convenience of combined formulation; same considerations as individual ingredients; (6) FOR COMPREHENSIVE SPORTS NUTRITION — adequate protein, carbohydrate timing, hydration, sleep, training periodization foundational; supplements adjunct; (7) LEUCINE / EAA / BCAA APPLICATIONS — leucine alone, EAAs, BCAAs all have research; full EAA generally superior to BCAAs alone; MuscleGuard's vegan leucine is anabolic trigger; (8) L-CARNITINE FOR EXERCISE — chronic supplementation needed for tissue accumulation; effects build over weeks/months; (9) BRAND VERIFICATION — MuscleGuard™ is Lonza trademark; specific proprietary formulation; (10) SPORTS NUTRITION FRAMEWORK — periodization, training, nutrition, recovery, supplementation hierarchy; supplements support but don't replace fundamentals.
