Why Does Your Body React to Beta-Alanine?


Have you ever consumed a pre-workout supplement and suddenly felt flushed, itching, and nearly shivering? You must have. Otherwise, you wouldn’t have searched “why does my body react to beta-alanine” on Google.

Many users of this supplement claim that right after taking it, they start to itch. Most of them end up wondering  why does beta-alanine cause an itching sensation.

The Science Behind Beta-Alanine

Beta-alanine is a naturally occurring amino acid that’s synthesized in the liver. Additionally, it can be found in trace amounts in foods like fish, poultry, and meat. When beta-alanine is consumed, it enters your bloodstream and travels to your muscles.

Carnosine is created in the muscles when beta-alanine and histidine mix. During strenuous exercise, carnosine is a buffer to help control the pH levels in the muscles. This, in turn, aids in preventing fatigue and boosting endurance.

Why Does Beta-Alanine Cause an Itching Sensation?

Paresthesia is the common itchy reaction to beta-alanine.

Although the precise mechanism causing paresthesia is not fully understood, it is believed to be connected to how beta-alanine affects skin nerve endings. It is believed that beta-alanine stimulates the sensory nerve fibres that cause itchiness.

Is the Itching Sensation Harmful?

The itchy feeling brought on by beta-alanine is typically transient and safe. After taking the supplement, it normally lasts for 15 to 30 minutes before it subsides.

Some people, however, might have a more severe reaction, like hives or trouble breathing. You should stop taking beta-alanine and visit a doctor if these symptoms occur.

Is It Safe to Take Beta-Alanine?

Beta-alanine is generally considered safe when taken in recommended doses. However, some individuals could encounter negative effects like gastrointestinal distress, nausea, or dizziness.

If you are considering taking beta-alanine, it is important to talk to your healthcare provider first, especially if you have any underlying medical conditions or are taking any medications.

How to Alleviate the Itching Sensation

If you experience an itching sensation after taking beta-alanine, there are several things that you can do to alleviate the discomfort:

  • Start with a Small Dose

Beta-alanine can be taken in lesser doses to lessen the severity of the itching. Doing so will give your body time to get used to the supplement and avoid a bad reaction.

  • Take Beta-Alanine with Food

Beta-alanine’s absorption can be slowed down, and the intensity of the itching can be decreased by taking it with food. Due to the food’s ability to slow down the digestive process, beta-alanine will have more time to be metabolized and absorbed into the bloodstream.

  • Use a Topical Cream

Itching can be reduced by rubbing an aloe vera or menthol-containing topical lotion on the afflicted area. These substances have a cooling impact on the skin, which may assist in lessening irritation and inflammation.


In conclusion, beta-alanine is a superb substance that can enhance workout performance in various ways. However, it is also known to cause the harmless skin-tingling sensation known as the Beta Alanine itch. While some people enjoy itching, others find it unpleasant. But it’s crucial to understand that it is not harmful and passes fairly quickly.
