Description

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.

FAQs
Frequently asked question

Is Beta Alanine-SR worth buying if I'm not a competitive athlete?

Absolutely. Beta Alanine-SR isn't just for athletes. Beta alanine levels naturally decline with age, so supplementing can help maintain muscle carnosine levels, support endurance, and provide antioxidant benefits for everyday active individuals. Whether you're hitting the gym occasionally or simply want to support healthy muscle function as you age, this product offers meaningful benefits beyond elite sports performance.

What makes Beta Alanine-SR different from regular beta alanine supplements?

The 'SR' stands for sustained release, meaning the formula delivers beta alanine gradually rather than all at once. This helps minimize the common tingling sensation (paresthesia) associated with standard beta alanine supplements while maintaining steady carnosine support throughout the day. It's a smoother, more comfortable experience without sacrificing effectiveness, making it a preferred choice for those sensitive to regular beta alanine formulas.

What does beta alanine actually do in the body?

Beta alanine is an amino acid that helps your body produce carnosine, which is stored directly in muscle tissue. Carnosine acts as a pH buffer, neutralizing acid buildup during exercise. This delays fatigue and reduces soreness, allowing you to train harder and longer. Without adequate beta alanine, your muscles produce less carnosine, which can limit performance and recovery.

How long does it take to feel results from Beta Alanine-SR?

Most users notice improved endurance and reduced muscle fatigue within two to four weeks of consistent daily use. Carnosine builds up gradually in muscle tissue, so patience is key. Taking Beta Alanine-SR regularly, rather than only on workout days, helps maximize muscle carnosine levels over time for the best performance and recovery benefits.

Why does beta alanine sometimes cause a tingling feeling?

The tingling sensation, known as paresthesia, is a harmless and common side effect of standard beta alanine supplements. It occurs when beta alanine is absorbed quickly into the bloodstream and activates certain nerve receptors. Beta Alanine-SR's sustained-release design significantly reduces this effect by releasing the ingredient gradually, making it much more comfortable to take for most people.

Does beta alanine decrease as you get older?

Yes. Research suggests that muscle carnosine levels, which depend on beta alanine, naturally decline with age. Lower carnosine means reduced buffering capacity in muscles, which can contribute to quicker fatigue and decreased physical performance over time. Supplementing with Beta Alanine-SR can help replenish these levels, supporting muscle health, endurance, and antioxidant protection as part of healthy aging.
