Beta-Alanine - The Next Creatine


What is it and where does it come from?

β-Alanine (C3H7NO2) is a nonessential amino acid and is the only naturally occurring beta amino acid.

Whereas α-alanine is found in many food sources including eggs, meat, chicken, plants and some dairy products, β-Alanine is made in the body by the enzyme beta-ureidopropionase via β-Alanine Synthase. β-Alanine is a breakdown product from carnosine and is also a component in pantothenic acid (Vitamin B-5).

It's sometimes called 3-aminopropionic acid.

What does it do and what scientific studies give evidence to support this?

Whereas α-Alanine supports healthy energy production, protein synthesis and enzyme function, β-Alanine does not play a role in protein synthesis and enzyme production and instead helps to promote high intramuscular carnosine concentrations.

By promoting high levels of intramuscular carnosine, β-Alanine promotes high energy levels and supports maximum muscular endurance and improved performance.

It's believed that creatine monohydrate and β-Alanine work together to maintain optimum muscle power output, as well as promoting a healthy body weight.

Who needs it and what are some symptoms of deficiency?

β-Alanine is not an essential nutrient and no symptoms of deficiency have been established.

By contrast, α-Alanine deficiencies, although rare, are marked by neurological deficiency, seizures, hypoglycemia, diabetes, hepatitis and even death.

How much should be taken? Are there any side effects?

Strictly follow label directions. Studies show that maximum benefit is observed after 10 weeks of use.

Consult your physician before using any dietary supplement.

Although rare, the genetic disorder hyper beta-alaninaemia has been reported and β-Alanine should not be used by people with this condition.

At high doses, a slight skin flushing effect can sometimes occur. This effect is harmless and goes away by lowering dosage amounts.


Don't post that information without providing your source.

I know plenty about beta-alanine, and all of this is old news. Calling it the next creatine is just stupid. Creatine is good for activities focusing upon power, whereas beta-alanine beneficial for overall muscular endurance.

My question is: have you supplemented with it? I'd like to read your feedback about it rather than scientific information and benefits and what not.

I've taken it and liked it. I did notice a slight increase in endurance without changing my eating or exercise habits. I'm not going to say it's a miracle supplement, but I believe many of those who engage in regular weightlifting or sports can see a possible benefit from it.


Hall of Fame
Beta-alanine shows PROMISE. But the studies haven't been done yet that will make it a block buster like creatine. Or, perhaps I should say, I haven't read the studies yet. :)

If the OP would care to provide the digests for a few such studies, we'd be ever so grateful.
