What Is Beta-Alanine?

Have you ever gotten those prickly tingles after taking a per-workout supplement? That's beta-alanine at work. It's one of the more common ingredients you'll find in pre-workouts because it's got some solid science behind it for improving high-intensity exercise performance. 

What Does Beta-Alanine Do?

Beta-alanine is a non-essential amino acid your body makes on its own, but it's also in meat and poultry. It combines with another amino acid, histidine, to form carnosine, which is a compound stored in your muscles. 

When you push hard during sprints, heavy lifting, or interval training, your muscles produce hydrogen ions that lower pH and cause that burning feeling you get when you're going all out and nearing fatigue. Carnosine buffers that acid buildup so your muscles can keep working before fatigue forces you to stop. Since beta-alanine controls how much carnosine your body can make, taking a supplement can help you make more. Studies show that taking beta-alanine can boost the carnosine in your muscles by about 20 to 80 percent after several weeks. 

Beta-Alanine Benefits

As you can probably tell by now, the main benefit of beta-alanine is boosting your performance during intense efforts that last only about 1 to 4 minutes. It can support you during quick, powerful movements like powerlifts, or heavy sets of 5-10 reps, short sprints, rowing intervals, or circuit training that cause your muscles to burn and push you to the edge.

Research shows beta-alanine helps you workout longer and increases the time it takes until you're completely exhausted. Athletes in fighting sports, swimming, or who do intense functional training have been shown to get better results with beta-alanine. For older people, it might help prevent fatigue from setting in as easily and help maintain their ability to exercise as they age.

Beta-alanine works best in the 1-4 minute effort range and won't help much with pure one-rep max strength, very short sprints under 10 seconds, or longer steady-state cardio. It's also not going to directly change your body composition, though it will help you get more out of your workouts by increasing the quality of your work.

Beta-Alanine Side Effects and Dosing

That tingling, prickly feeling, called paresthesia, is the major side effect of beta-alanine. It usually hits your face, neck, and hands for about 10 to 20 minutes and is completely harmless. The larger the dose you take, the more tingling you'll likely get, so if it bothers you, you can split up the dose into smaller amounts or use a sustained-release form.

Aside from that tingling, beta-alanine is very safe. Risk assessment analysis covering over 100 human studies found no adverse effects when taken at the typical 3-6 gram dose. There's not much long-term data over a year, so if you have a serious medical condition, talk to your doctor before starting.

Proper Dosing and How Much Beta-Alanine is Too Much

Research supports taking between 3.2 to 6.4 grams per day, which can be split into smaller doses of 0.8 to 1.6 grams every three to four hours. Some brands underdose when it's part of a pre-workout, so be sure to check the label to see if you should add a bit more. 

Purist® Pre-Workout Powder includes a research-backed dose of beta-alanine, along with caffeine and nootropics, all third-party tested for purity. On rest days, you can take beta-alanine on its own to keep your levels topped up.

Going over 6.4 grams hasn't been shown to provide any extra benefits and will likely just make the tingling sensation worse. Staying within the studied range is the safest bet.

When to Take Beta-Alanine

Beta-alanine is similar to creatine in that it works best when you take it daily over several weeks to load up the muscles. You can take it with meals, in a shake, or with other supplements. 

The timing isn't really important, though you'll often find beta-alanine in pre-workout formulas, as some people like how the tingling effect makes them feel when they work out, as though it gives them a psychological boost to know it's working. 

Takeaway

Beta-alanine is a researched backed supplement that's worth a look, along with the gold standard creatine as a go-to for training performance. It increases muscle carnosine levels, buffers acid to reduce muscle fatigue during intense efforts, and helps you get more out of your training before getting tired. Use it consistently to see the best results. 

FAQs

What are the benefits of taking beta-alanine and creatine together?

Beta-alanine and creatine affect different energy systems, so they work well together. Creatine helps regenerate ATP for explosive power, while beta-alanine buffers acid buildup during sustained intense efforts (1-4 minutes). They work together well, supporting short bursts and slightly longer high-intensity sets.

How does beta-alanine enhance the effects of creatine?

Beta-alanine doesn't directly enhance the effects of creatine since they work through different pathways. Creatine recycles ATP while beta-alanine raises carnosine to buffer acid in the muscles. Stacking them can support your performance even more because creatine helps with quick power while beta-alanine helps you sustain higher intensity work through 1-4 minutes.

Which is better for muscle performance: beta-alanine or creatine?

If you had to pick just one, creatine has stronger overall evidence for improving strength, power, and lean mass. Beta-alanine is better for more sustained high-intensity work where acid buildup is the limiting factor. Ideally, you'd use both since they serve different purposes and are safe to take together.

Are there any side effects of combining beta-alanine with creatine?

There are no side effects that are caused by combining beta-alanine and creatine. Taking them together doesn't make any side effects, like tingling, worse. They're both very safe supplements and are often used together in studies.

What should I consider when choosing a beta-alanine supplement for workout performance?

Look for a product that includes a research backed dose, uses transparent labeling so you know exactly how much you're getting, and is third-party tested. Avoid any blends that hide ingredient amounts. 

How does NSF certification impact the quality of beta-alanine supplements?

NSF Certified for Sport is an independent certification that checks if a supplement contains exactly what the label says and that it doesn't have any substances banned in sports. This certification is highly trusted for athletes or anyone who wants to be sure about the quality of their supplements.

How should I take creatine and beta-alanine for optimal results?

Take about 5 grams of creatine and 3-6 grams of beta-alanine (split doses of 1.6g is fine) every day. Both work best when you're consistent with it and it doesn't really matter when in the day you take them. You can take them pre-workout or with meals. Give them at least 3-4 weeks of daily use to see results.
