What to Expect From
Since the first published human study in 2006, beta alanine (BA) has quickly grown into one of the most popular sports supplements on the market (1).
Yes it has been shown to work and be safe, but it has also been shown to have a strange side effect.
Want to know what you'll experience when taking BA? Read on...
NOTE: The below only applies of you are correctly dosing BA. If you are taking BA as part of a pre-workout,
chances are you aren’t dosing it properly. To find out more click here:
Lower Lactic Acid = Higher Performance
BA has been shown to increase muscle carnosine concentrations (2, 3), a substance that "buffers" or reduces muscle lactic acid build up caused by intense exercise (4). Acidity is thought to play a big factor in causing muscle fatigue, so it’s no surprise that taking BA results in improve performance in athletes participating in strength and power sports, where the acid "burn" is frequently experienced (5).
Studies have show that it can take as little as 2 weeks of regular BA use to increase muscle carnosine (6). Better still, it looks like this doesn’t stop, with studies of up to 24 weeks showing continued carnosine build up (7).
Improved Cognitive Function
A Crazy Study on Soldiers
Carnosine is found in other parts of the body, such as the brain. Where the lactic acid theory may not run as true in these tissues, there does seem to be some interesting benefits. One is increased alertness and cognitive function when training (8).
As if math wasn't stressful enough on its own, a 2015 study on soldiers had them undertake a complex math test following a 30-metre sprints and a shooting accuracy test... while in combat gear... beside people firing guns (9). This crazy study found that those who had taken BA did better than those who didn't.
BA's stimluatory effect may also work after just a single dose. A group from Texas A&M found that a simple BA pre-workout is all it took to see evidence of improved perception and readiness to perform (10).
The Catch... A Side Effect
There is a common and very noticeable side effect of taking BA: Paresthesia (2). Parasthesia is a sensation of tingling of the skin. It’s like having prickles run up your arms and over your face.
Yes, it sounds strange and a little unnatural, but Studies have shown there to be no negative outcome of parasthesia, and BA has an excellent safety profile to date (9). Some report even liking the strange sensation.
Paresthesia generally disappears within 60–90 minutes (11), and it can be almost avoided by reducing dosage or taking it with real food/on a full stomach (2).
