Beta-Alanine

What is it?

Beta-Alanine is a naturally occurring non-essential amino acid which is synthesised within the liver, however, the main source is within the diet, namely protein rich meats such as chicken and turkey. It is a modified form of the amino acid alanine. It plays a role in regulating the amount of acid formation within the muscle through forming Carnosine; an acid buffer. It enhances the body’s ability to resist fatigue and preserves the muscle’s contractile function.

 

Indications

Beta-alanine is recommended for anyone involved in sports which lead to accumulation of lactic acid, such as weight lifters, endurance athletes and prolonged, intense sports.

 

How much should I take?

It is recommended to take 4-6g of Beta-Alanine in divided doses of 3-4 times per day. One should take it continuously for 6-8 weeks with a 2 week break to follow.

 

Research

Research has shown that supplementation with Beta-Alanine leads to an increase in endogenous Carnosine levels. The degree of increase is greater in those whom are untrained, but it remains to be a significant increase in the trained group as well. The results are noticed within the first 4 weeks and continue to increase, peaking at 8 weeks of supplementation.

This has been shown to delay muscle fatigue during the later stages of a weights training session. It has been demonstrated that it can help maintain and increase muscle mass during high intensity interval training. Finally, it has been shown to enhance endurance and increase “Total Work Done” power output and anaerobic running capacity. It has also been shown to reduce fatigue.

 

Side effects

The main side effect worth noting associated with Beta-Alanine is skin tingling which lasts no more than 2 hours.
