Syntech SR CarnoSyn Beta Alanine | 120 tab

Beta Alanine is a naturally occurring beta amino acid that is produced in the liver. Beta alanine has been identified as a precursor of carnosine synthesis. Beta Alanine can increase carnosine concentrations, causing biochemical processes to postpone muscle fatigue. It is suitable for sports, where the high intensity persists.




Sustained Release CarnoSyn® Beta Alanine

When it comes to purity, safety and efficiency, there is no other type of beta-alanine that matches the level of CarnoSyn®, patented and globally recognized as the reference point for beta-alanine quality. The latest innovation from CarnoSyn® is a tablet with it Sustained Release System. This means that beta-alanine stays in the body longer and is absorbed better.

The only side effect of beta-alanine is paraesthesia; tingling on the skin, which often occurs in the limbs (hands, feet, arms, legs) and face. To prevent tingling, beta-alanine had to be taken several times during the day in small doses. With SR CarnoSyn® this is a thing of the past, because thanks to the SR System, more beta-alanine is being released gradually.

How works Beta Alanine?

Creatine works primarily on the ATP-CP Energy System. Once the creatine phosphate supply is empty (after 10 seconds), the body mainly uses glucose as an energy source. Due to the breakdown of glucose or glycogen during high intensive efforts, the body produces lactate and H + ions (Lactic Acid System, see Figure 1). The accumulation of H + ions is the cause of muscle acidification. The body can itself buffer the ions with the help of carnosine, but only to a certain extent. As long as the training continues, the carnosine levels will no longer be sufficient. This leads to muscle fatigue and a decrease in strength.

Energy Systems

Figure 1: Energy pathways (

Beta-alanine is a non-essential amino acid. Together with the amino acid L-Histidine, it produces Carnosine. The body normally has enough L-Histidine, but beta-alanine must be taken through the diet. Beta-alanine is present in low concentrations in poultry, fish and meat.

In most sports the body uses not one, but multiple energy systems. This depends on the intensity and duration of the training. Beta Alanine is very efficient for sustained high intensity efforts, starting from 30 seconds to 4 minutes. To optimize the different energy systems, beta-alanine is often combined with creatine.
