Beta-Alanine: Muscle Power Boost
Beta-alanine supplements may improve muscle endurance and power for athletes.
In brief
Beta-alanine supplements may improve muscle endurance and power for athletes. Beta-alanine helps athletes build muscle endurance and power by increasing carnosine levels in muscles. Originally reported by Men's Health.
Quick answers
- What Is Beta-Alanine?
- Beta-alanine is a nonessential amino acid your body can naturally produce through food alone.
- How Does Beta-Alanine Work?
- It helps create carnosine, a molecule stored in muscles that improves performance and reduces fatigue.
- What is the key takeaway from Beta-Alanine: Muscle Power Boost?
- Beta-alanine helps athletes build muscle endurance and power by increasing carnosine levels in muscles.
What Is Beta-Alanine?
Beta-alanine is a nonessential amino acid your body can naturally produce through food alone.
“BETA-ALANINE IS A nonessential amino acid, meaning your body can naturally produce all it needs through food alone”
How Does Beta-Alanine Work?
It helps create carnosine, a molecule stored in muscles that improves performance and reduces fatigue.
“Beta-alanine is used to synthesize carnosine, a molecule that is stored in muscles and helps improve performance”
Benefits for Athletes
Research shows beta-alanine boosts muscular endurance and power, especially for fast-twitch muscle fibers.
“Researchers studying beta-alanine’s effects on athletes found potential benefits for sustaining muscular endurance and power”
Beta-Alanine vs. Creatine
Beta-alanine is not creatine; both are amino acids but work differently to improve athletic performance.
“Beta-alanine is an amino acid that is a building block of carnosine, while creatine is a molecule made up of three different amino acids”
Side Effects of Beta-Alanine
High doses cause tingling (paresthesia), but it is generally safe at recommended levels.
“Problems start to come up when you’re taking a single high dose. The most common side effect is paresthesia, or tingling of the skin”
Food Sources of Beta-Alanine
Beef, chicken, fish, and dairy contain beta-alanine, but vegans may need supplements.
“Among the top food sources of carnosine (and thus beta-alanine) are animal products, including beef, chicken (and chicken broth), and fish”
When to Take Beta-Alanine
Vegans and those with low dietary intake may benefit from supplements for better muscle performance.
“The two cases where you may want to consider beta-alanine supplements are if you’re a vegan/vegetarian athlete or if your doctor recommends it”
The key point
Beta-alanine helps athletes build muscle endurance and power by increasing carnosine levels in muscles.
