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 these, 4 g are BCAAs (leucine, isoleucine, 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—as well as 40 mg of caffeine and extracts of green tea and green coffee.

The body cannot produce essential amino acids on its own, so they 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: L-leucine at 2,667 mg, followed closely by L-lysine at 2,500 mg—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. From 4 g of BCAAs, you therefore get 2,667 mg of leucine, 667 mg of isoleucine and 667 mg of valine. Of all amino acids, leucine is the one most frequently studied in muscle research.¹

Leucine acts as a trigger for the mTOR signaling 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 proportion of leucine, is an advantage over standard BCAA products.

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

With plant extracts, what matters is how much active ingredient they actually contain. With ProEAA, you know this for 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.
