Beta-Alanine

What is beta-alanine?

Beta-alanine is an amino acid your body makes itself, and in muscle it combines with histidine to form carnosine. The ISSN (International Society of Sports Nutrition) position stand describes carnosine as an intracellular pH buffer, which means it helps soak up some of the acid that builds up in muscle during hard exercise.

In this collection you'll find standalone beta-alanine products, pre-workouts that list beta-alanine among their ingredients, and a small number of carnosine supplements. We stock them side by side so you can compare the amount per serving.

What does beta-alanine do?

Taken daily for several weeks, beta-alanine raises the amount of carnosine stored in your muscles. The ISSN position stand reports that 4 to 6g a day for four weeks raised muscle carnosine by up to 64%, and by up to 80% after ten weeks, although the response varies from person to person.

On performance, the ISSN position stand says daily use of 4 to 6g for at least two to four weeks has been shown to improve performance in research, with the clearest effects in hard efforts and time trials lasting about one to four minutes. It also says more research is needed on strength and on endurance exercise lasting longer than about 25 minutes. Beta-alanine has no authorised health claim in Great Britain, so we don't make performance claims for any product here.

How much beta-alanine per day?

The amount studied in the ISSN position stand is 4 to 6g a day, taken in divided doses of 2g or less for at least two weeks. The position stand says single large doses caused more tingling and did not improve performance.

Some pre-workouts contain less than this per scoop, so check the label. A product with 1.6g per serving gives you a little over a quarter of a 6g daily amount. Our guide to reading a supplement label shows where to find the amount per serving.

If you take beta-alanine in a pre-workout, reaching 4g or more usually means more than one serving, which also means more of every other ingredient, including any caffeine.

Why does beta-alanine make you tingle?

The tingling is called paraesthesia, and the ISSN says it is the only reported side effect of beta-alanine. It is usually felt in the face, neck and backs of the hands, depends on the dose, and typically fades within 60 to 90 minutes.

The position stand says the tingling is not considered harmful, and that smaller split doses of around 1.6g, or a sustained-release product, can reduce it. Some people find it unpleasant, which is one reason pre-workouts without beta-alanine are searched for.

Is beta-alanine safe?

The ISSN position stand says beta-alanine currently appears to be safe in healthy populations at recommended doses. It also notes there are few studies lasting longer than a year.

If you have a medical condition, take medication, or are pregnant or breastfeeding, speak to your GP or pharmacist before taking any supplement. If the product also contains caffeine, EFSA says healthy adults can have up to 400mg of caffeine a day from all sources, and single doses up to 200mg.

When should you take beta-alanine?

Timing matters less than taking it every day, because beta-alanine works by building up carnosine over weeks rather than acting on the day. The ISSN position stand describes daily intake over at least two to four weeks.

Splitting the daily amount into doses of 2g or less, spread through the day, is the approach the position stand describes to limit tingling. Follow the directions on your product label.

Can you take beta-alanine with creatine?

Yes, many people do, and the ISSN position stand says combining beta-alanine with other supplements may be useful when the beta-alanine dose is high enough (4 to 6g a day) and taken for at least four weeks. The two work in different ways.

Creatine has an authorised claim: it "increases physical performance in successive bursts of short-term, high intensity exercise", which only applies at a daily intake of 3g of creatine. Compare creatine products in our creatine guide.

Pre-workout with or without beta-alanine?

It depends on whether you want beta-alanine, and how much of it. A pre-workout gives you beta-alanine alongside other ingredients; a standalone product lets you control the dose separately from caffeine.

"Some brands also use proprietary blends, making it difficult to establish exactly how much of each active ingredient you're getting," says Andy Arshad, who runs SupplementHQ. "Others clearly disclose their ingredient quantities, making comparisons much easier." Compare formulas in our pre-workout guide, or see stim-free pre-workouts if you want to avoid caffeine.

How do you compare beta-alanine value?

Work out the cost per gram of beta-alanine, then the cost of your daily amount. The tub price alone doesn't tell you this.

How to compare value (example figures, not real products): a £15 tub of 300g pure beta-alanine powder costs 5p per gram, so 4g a day costs 20p. A £30 pre-workout with 30 servings of 1.6g beta-alanine costs £1 per serving; you'd need 2.5 servings to reach 4g, which is £2.50 a day, though you're also paying for the other ingredients.

"We think customers should compare the actual amount of active ingredients they're getting, rather than just the format or marketing," says Andy. For other training supplements, browse all gym & sports performance supplements.
