Beta-Alanine - What is it, how to take it and… does it work?

A complete guide to Beta-Alanine

If you use or have used any supplements pre workout, this name is probably not unfamiliar to you, since the Beta-Alanine it is more and more usual presence in this type of products.

Theoretically, you can achieve greater muscular endurance, more strength and an improvement in your body composition with this supplement, but ... is it true?

Find out in this article.

What is Beta-Alanine?

First of all, to know more about this supplement, you need to know more about Carnosine, as the role of Beta-Alanine and the mechanism by which it works, is by increasing Carnosine levels.

Carnosine is an amino acid that, by attenuating the increase in acidity in the muscles, allows them to exercise for longer, especially in short/medium duration and medium/high intensity activities, such as hypertrophy training.

In practice, by increasing Carnosine reserves, we get, for example, one or two more repetitions at the bench press, or if you are a fan of HIIT training, greater tolerance to the sprint phase (and consequently better performance).

So, how do we increase Carnosine levels?

With Carnosine supplementation?

Yes, it is possible to increase Carnosine levels by supplementing the amino acid itself.

But ... it is not the most effective way.

Muscle cells cannot effectively absorb Carnosine, therefore, Carnosine which is a “combination” of Beta-Alanine and L-Histidine, is transformed into these two precursors to get inside the muscle cells, and be synthesized into Carnosine inside of the muscle.

The most effective way to increase Carnosine levels within the muscle (where we need it) is through the supplementation of Beta-Alanine, which when entering muscle cells is synthesized in ... Carnosine!

And the oral supplementation of Beta-Alanine is really effective in this task.

Benefits of Beta-Alanine

The main benefits of this supplement are:

  • More performance
  • More lean mass
  • Less fatigue
  • More resistance

But, is it effective?

Yes, it appears to be effective in several contexts, but not in all.

You greatest benefits occur mainly in moderate / intense intensity activities, with a duration of between 60 to 240 seconds.

In other words, if you are a strength athlete and / or train with low repetitions (less than 8), it is possible that Beta-Alanine is not the right supplement for you.

Now, if you use eight or more repetitions per set, or if you’re a fan of superseries, Beta-Alanine can help.

O HIIT training is another example where this supplement works.

Beta-Alanine can reduce fatigue, as well as the perception of fatigue, that is, it acts not only on the muscular level but also on the mental level in a positive way. (1)

Studies and Beta Alanine

A comparison was made between training HIIT with and without Beta Alanine for 6 weeks.

Both groups lowered the percentage of fat body, but the group that used Beta-Alanine also had an increase in muscle mass.(2)

It was also concluded that supplementation with Beta-Alanine more Creatine leads to greater gains in lean mass than just Creatine. (3)

In addition to gains in lean mass, it also brings benefits in terms of endurance and performance. (4)

Finally, Beta-Alanine supplementation was tested in conjunction with resistance training, in which the protocol used was 6 sets of 12 repetitions in the squat. (5)

The result?

A difference of 22% in the total number of repetitions, favorable to the group that used Beta Alanine.

A Beta-Alanine supplement

There are studies that demonstrate benefits in short-term exercises, but there are also several that show that it is not worthwhile in this type of activity (6), that is, there may or may not be a benefit.

If your goal is to increase lean mass, what you will notice with this supplement is above all a greater ability to get one or two more repetitions in your series, especially if you use higher repetitions.

Less than eight repetitions is probably not worth using this supplement, although there may be advantages, apparently they are not significant, or at least that's what scientific studies say!

Where to buy Beta-Alanine?

You can easily find Beta-Alanine supplements in any supplement store, but as usual, Myprotein combines quality at a good price and is available here the Beta-Alanine of this brand.

How to take Beta-Alanine? 

The dosage should be at least 2g a day, and it can go up to 5g a day.

One of the side effects of Beta-Alanine is a tingling sensation in the body, and if you've ever used a pre-workout supplement with Beta-Alanine, you probably already know about this effect.

Take it easy ... this happens only in some people, and usually in high doses.

In addition, this effect has no negative consequences, it is somewhat harmless.

The ideal if you have this effect, is to divide the dose of Beta-Alanine in several doses throughout the day.

This supplement should preferably be taken with meals as it is most effective this way.

Ideally, it should not be combined with Taurine, as they can “get in the way” of absorption.

Oh, and you don’t need to use Beta-Alanine in the pre-workout, since its effect is cumulative (similar to Çreactor), and not immediately, that is, if you take it today for the first time the only thing you can notice is the tingling.

You usually start to feel its effects after 1 to 2 weeks, depending on the dose used.

  1. Is it advisable to take it every day even if you don't train? And by the way, should you stop for example 1 week after 8 weeks of taking it?


      Hi Diogo.

      There is not much information related to long-term use (+12 weeks), however, the ideal seems to be to take a break after 8-12 weeks of use.
