A Longevity.Technology brand, FLT‘s latest supplement leverages advanced science to redefine muscle health and recovery.
Featuring PeptiStrong – an innovative ingredient developed by Nuritas – this product aims to support muscle strength, recovery, and endurance.
To understand the innovation behind PeptiStrong and the formula’s additional components, Phil Newman of Longevity.Technology spoke with Andy Franklyn-Miller, Chief Medical and Innovation Officer at Nuritas.
AI and peptides
“Peptides are essentially small chains of amino acids,” explained Andy Franklyn-Miller. “Unlike individual amino acids, which we consume as fuel, peptides work through targeted mechanisms to optimize physiological functions.”
PeptiStrong is a unique combination of peptides sourced from plants, identified and tested using Nuritas’ proprietary AI platform.
“Our database contains over 9 million peptides identified from plants,” Franklyn-Miller shared. “AI allows us to filter candidates based on desired biological activities, dramatically reducing the time required to identify effective peptides.”
Traditional methods of peptide discovery would have taken centuries to identify combinations with the desired attributes; thanks to AI and rigorous biological testing, Nuritas pinpoints peptides with unparalleled precision, ensuring they are absorbable, effective, and safe.
Clinical evidence supporting PeptiStrong
PeptiStrong’s efficacy is supported by robust clinical trials:
Immobilization trial
In a study simulating muscle loss, participants were immobilized in casts for one week. Compared to milk protein, PeptiStrong delivered superior results.
“Two weeks post-cast removal, the milk protein group regained 60% of their strength, while the PeptiStrong group surpassed 100%,” Franklyn-Miller noted. Muscle biopsies revealed PeptiStrong stimulated four times the protein synthesis of milk protein.
Recovery and strength trial
A separate trial involving exhaustive leg extensions demonstrated PeptiStrong’s impact on recovery. “Participants showed a 70% improvement in fatigue resistance and increased strength within 72 hours,” Franklyn-Miller explained. “This translates to practical benefits – like climbing stairs or completing workouts with less strain.”
Aging and muscle preservation
Aging reduces the body’s ability to synthesize protein efficiently. “PeptiStrong overcomes this challenge by activating genetic pathways to drive protein synthesis,” Franklyn-Miller said.
“It’s particularly effective in individuals over 50, helping maintain muscle mass even with dietary variations.”
Synergy with other ingredients
PeptiStrong is complemented by a carefully selected blend of ingredients, each serving a unique role:
- Creatine: “PeptiStrong matches creatine’s ATP production while significantly boosting protein synthesis,” Franklyn-Miller highlighted.
- L-Glutamine: Essential for muscle recovery, it works through mechanisms different from PeptiStrong, making the combination particularly effective.
- Magnesium: Increased magnesium levels help meet the demands of physical activity.
- Zinc: Helps combat the effects of aging.
- Electrolyte blend of sodium, calcium, and potassium: Promotes hydration, muscle function, and overall health.
Addressing muscle health for longevity
Muscle health is a cornerstone of overall longevity. “Research shows that muscle strength reduces all-cause mortality by up to 21%,” Franklyn-Miller emphasized.
“By preserving and enhancing muscle function, PeptiStrong offers tangible benefits for both current performance and future health.”
A sustainable future for supplements
In addition to its scientific merits, PeptiStrong aligns with sustainability goals. “Our peptides are plant-derived, ensuring minimal environmental impact,” Franklyn-Miller explained. “We prioritize low-carbon production methods while maintaining rigorous purity standards.”
The future of AI in supplement development
Looking ahead, Nuritas continues to push boundaries in AI-driven health solutions. Franklyn-Miller shared: “We’re exploring peptides for diverse applications, from glucose metabolism to cognitive support. AI enables us to accelerate discovery and deliver clinically validated solutions at unprecedented speed.”
Closing thoughts
PeptiStrong included in FLT MUSCLE represents a new frontier in muscle health, combining innovative science with practical benefits.
As Franklyn-Miller concluded: “Our mission is to improve health and longevity through clinically proven, sustainable ingredients. PeptiStrong embodies this vision, offering individuals the tools to thrive today and in the future.”
