Benefits
63% increase in composite muscle score (no exercise)
Published Nutrition & Metabolism clinical trial: 42 healthy adults aged 55-70 randomized 3-arm to MuscleGuard combination, L-carnitine alone (1500 mg), or placebo for 8 weeks. Composite score of muscle mass, strength, and physical activity was 63% greater with MuscleGuard vs placebo (statistically significant). Critically: results achieved without diet or exercise modification.
1.0 kg lean muscle mass increase
Same trial: MuscleGuard recipients showed 1.0 kg increase in total lean muscle mass and leg lean muscle mass vs baseline. Muscle gain without exercise is unusual and clinically meaningful — particularly for the 55-70 age group with sarcopenia (age-related muscle loss) concerns. Validates anabolic synergy of the four-nutrient combination.
1.0 kg lower leg strength increase
Trial documented 1.0 kg increase in lower leg strength in the MuscleGuard group. Lower leg strength is particularly important for older adults — supporting mobility, fall prevention, and independent living. Functional strength improvement complements the lean mass gain — addressing both quantity and quality of muscle.
L-carnitine alone insufficient — synergy validated
Three-arm trial design uniquely validates the synergy: L-carnitine alone did not create significant change vs placebo. Only the four-nutrient MuscleGuard combination produced significant muscle benefits. Establishes that the patent-pending ratio is essential — not just any combination of these nutrients works the same way.
Healthy aging muscle preservation
Muscle degeneration (sarcopenia) is common among older adults — accelerating from age 50 onwards. MuscleGuard's 55-70 age group trial validates application for healthy aging. Increased lean muscle mass without exercise is profound for vulnerable populations who may not tolerate intensive exercise programs. Addition of exercise expected to potentiate effects further.
Pre-, intra-, and post-workout flexibility
MuscleGuard offers nutritional support for pre-, intra-, and post-workout applications. Available as standalone supplement or easily incorporated into existing sports nutrition regimes including protein powders and shakes. Convenient flexibility supports diverse consumer preferences and use cases.
Vegan synergistic L-carnitine + creatine + leucine
All four MuscleGuard components derived from vegan sources — including L-carnitine (typically animal-sourced) via Lonza's Carnipure® and a uniquely vegan leucine source. Addresses growing demand for plant-based sports nutrition. Vegan and vegetarian consumers gain access to combinations typically requiring animal-source ingredients.
Both genders + multiple demographics
Patent-pending MuscleGuard formulation is ideal for use by both male and female athletes and active individuals — supported by clinical trial including both genders. Sports nutrition market is increasingly broadening beyond bodybuilders to active men and women regardless of age. MuscleGuard supports this expanded consumer base.
Mechanism of action
L-Carnitine fatty acid oxidation
L-Carnitine (Carnipure® 1500 mg) is critical for transport of fatty acids into mitochondria for energy production. Supports muscle energy metabolism, exercise capacity, and recovery. Carnipure is the branded high-purity L-carnitine. Single ingredient alone insufficient — must be combined with other MuscleGuard components for muscle benefits.
Leucine mTOR activation
L-Leucine (2000 mg) is the most potent BCAA for activating mTOR (mechanistic target of rapamycin) — the primary signaling pathway driving muscle protein synthesis. Leucine is the 'trigger' amino acid for anabolic muscle building. 2000 mg dose is within the effective range (typically 1.5-3.0 g per dose) for mTOR activation.
Creatine phosphate energy system
Creatine (3000 mg) supports the ATP-PCr energy system — primary energy source for high-intensity, short-duration activities. Creatine is one of the most well-researched sports nutrition ingredients. 3 g/day supports steady-state muscle creatine levels. Foundation for strength and power applications.
Vitamin D3 muscle function support
Vitamin D3 (10 μg = 400 IU) supports muscle function via vitamin D receptors on muscle cells. Vitamin D deficiency contributes to muscle weakness and sarcopenia — particularly in older adults. The 400 IU dose addresses baseline insufficiency rather than acute deficiency.
Patent-pending synergistic ratio
The specific ratio (1500/2000/3000/10) is patent-pending — reflecting Lonza's clinical validation of the synergistic effects. Three-arm trial design demonstrates that L-carnitine alone is insufficient — the synergy requires all four components. The patent protection supports commercial differentiation in sports nutrition.
Clinical trials
Randomized double-blind placebo-controlled clinical trial in healthy older participants. Three-arm design: MuscleGuard combination (1500 mg L-carnitine + 2000 mg L-leucine + 3000 mg creatine + 10 μg vitamin D3) vs L-carnitine alone (1500 mg) vs placebo for 8 weeks. Published in Nutrition & Metabolism (Evan M et al., 2017, vol 14: 7).
42 healthy adults aged 55-70 years. 8-week intervention. Three randomized arms.
Composite muscle score (mass, strength, physical activity) statistically significantly increased 63% with MuscleGuard vs placebo. 1.0 kg increase in total lean muscle mass, leg lean muscle mass, and 1.0 kg in lower leg strength vs baseline. L-carnitine alone did not create significant change vs placebo — validating synergy. Without diet or exercise modification.
Class evidence supporting Lonza's Carnipure® L-Carnitine — the high-purity L-carnitine component of MuscleGuard. Carnipure has been studied for exercise performance, muscle recovery, infant and clinical nutrition applications. Long research base supporting the L-carnitine component.
Various — extensive Carnipure research base across exercise and clinical nutrition applications.
Carnipure L-carnitine supports exercise performance and muscle recovery via fatty acid oxidation mechanism. MuscleGuard's three-arm trial uniquely demonstrates that L-carnitine alone is insufficient for muscle benefits in the older population — requires combination with leucine, creatine, and vitamin D3 for synergistic effects.
Class evidence supporting individual MuscleGuard ingredients in sports nutrition. Creatine has extensive research base for strength and power. Leucine drives mTOR activation and muscle protein synthesis. Vitamin D3 supports muscle function. MuscleGuard's contribution is the validated synergistic combination.
Various — sports nutrition research base across creatine, leucine, vitamin D3.
Individual ingredients have well-documented effects: creatine supports ATP regeneration, leucine activates muscle protein synthesis, vitamin D3 supports muscle function. MuscleGuard's clinical trial validates the specific combination ratio. Distinguishes from generic ingredient stacks without clinical validation of the specific combination.
