Beta alanine, an amino acid, plays an integral role in muscle health and endurance.* Beta alanine enables the body to produce carnosine, which is stored in muscle. Carnosine buffers the pH of muscle tissue so it produces energy efficiently without excessive lactic acid buildup, which can cause fatigue and soreness.*

Beta alanine is not just for athletes. Beta alanine muscle content also decreases with age. This, combined with powerful antioxidant support, makes Beta Alanine-SR a great option for aging individuals who wish to support muscle health and longevity.*

The best food sources of beta alanine are animal protein like meat and fish. Because the best food sources of beta alanine are animal protein, like meat and fish, individuals who are vegetarian or follow a mostly plant-based diet have less carnosine in their muscles compared to individuals who eat more animal protein.

Benefits of Beta Alanine-SR:

  • Train harder and longer by supporting muscle health and output*
  • Optimize training by increasing perceived time-to-exhaustion*
  • Clinically studied for benefiting athletic performance*
  • Supports muscle pH to resist fatigue and delayed onset muscle soreness*

Who can benefit:

  • Athletes and fitness enthusiasts wanting to optimize their training*
  • Aging individuals wanting to optimize and maintain muscle mass*
  • Individuals wanting to limit animal protein in their diet

Beta-Alanine: An Emerging Cognitive Tool for Tactical Athletes

Military operators are often called "tactical athletes” due to their physical capabilities and demands rivaling that of competitive athletes. They must be very fit to perform their duties, which include running, reacting quickly with explosive power and speed, and carrying heavy loads for long distances on foot. Along with physical fitness, operators also require a high level of cognitive function to make decisions while dealing with physical and mental stress and fatigue.

But it's not just athletes who can benefit from beta-alanine. It has also been shown to be effective in improving exercise capacity and promoting longevity in older adults and non-athletes as well.*

Learn how supplementing with beta-alanine has been shown to increase carnosine levels in the muscles, which can lead to improved endurance and performance during high-intensity activities like sprinting, weightlifting, and other anaerobic exercises.*
