ProEAA - GymBeam

ProEAA is a powdered sports drink that combines all nine essential amino acids with six vitamins, caffeine and two standardized plant extracts.

Each 10 g serving provides 8.5 g of essential amino acids. Of this, 4 g consists of BCAAs (leucine, isoleucine and valine) in a 4:1:1 ratio. The profile also includes 2,500 mg of L-lysine, 600 mg of L-threonine, 400 mg of L-phenylalanine, 400 mg of L-histidine, 300 mg of L-tryptophan and 300 mg of L-methionine.

The amino acids are complemented by nine other active ingredients: six vitamins—vitamin C, niacin, vitamin B6, folic acid, vitamin B12 and vitamin D in the form of cholecalciferol—plus 40 mg of caffeine and extracts of green tea and green coffee.

Essential amino acids cannot be produced by the body and must be obtained from food. There are nine of them, and ProEAA contains all nine, providing a total of 8.5 g per serving.

Two of them are present in the largest amounts: 2,667 mg of L-leucine, followed closely by 2,500 mg of L-lysine, each accounting for almost a third of the total amino acid profile. Lysine is often the least abundant amino acid in grains and plant-based diets in general, making it the most common limiting amino acid.

ProEAA contains BCAAs in a 4:1:1 ratio, with four parts leucine for every one part isoleucine and valine. A 4 g serving of BCAAs therefore provides 2,667 mg of leucine, 667 mg of isoleucine and 667 mg of valine. Of all amino acids, leucine is the most frequently studied in muscle research.¹

Leucine acts as a trigger for the mTOR signalling pathway, which initiates muscle protein synthesis.¹,² It has the strongest effect in this respect of all amino acids, which is why the 4:1:1 ratio, with twice the leucine content of standard BCAAs, is an advantage.

Leucine alone, however, is not enough. A study of resistance-trained men after strength training showed that BCAAs enhance mTORC1 activation more than leucine alone, and the complete range of essential amino acids enhances it even more than BCAAs.² The other essential amino acids work together with leucine. That is why ProEAA contains all of them.

With plant extracts, what matters is how much active ingredient they actually contain. With ProEAA, you know the amount in both.

The product is manufactured in a facility certified to ISO 22000:2018 and IFS v.8. We also regularly test it for heavy metals and microbiological purity.
