In the dynamic field of sports nutrition and health care, a new question arises: Is the traditional protein shake still enough to optimally nourish our bodies? Some experts say no and focus on amino acids, the true building blocks of life. Proteins, also known as albumen, are essential for building bones, muscles and healing wounds. But without amino acids – the smallest units of proteins – none of these functions would be possible. In addition to water, the human organism mainly consists of these complex compounds, which are not only central to tissue structure, but also to the synthesis of hormones and neurotransmitters.

The classification into essential and non-essential amino acids determines which of the 20 proteinogenic amino acids the body can produce itself and which it must consume through food. During digestion, proteins are broken down into these amino acids and absorbed in the small intestine - a crucial step for protein biosynthesis in our cells.

The quality of proteins in our diet plays a big role: complete proteins contain all the essential amino acids, while incomplete proteins must be combined to achieve a complete amino acid profile.

But why are protein shakes no longer enough? They contain isolated proteins that the body must first break down, while free amino acids can be absorbed immediately. Supplementing amino acids can provide useful support, especially for athletes, vegetarians or vegans.

EAA and BCAA are two different types of nutritional supplements available in the market. While BCAAs only contain three essential amino acids, EAAs offer all eight and are therefore more effective.

The role of cofactors such as vitamin B6 should also not be underestimated. This vitamin is essential for the conversion of amino acids and should be included in every EAA product. Our recommendation: Pay attention to the completeness of the essential amino acids and the use of bioactive vitamin B6 in the form of pyridoxal-5-phosphate. The best time to take amino acids is directly before, during or after training - away from meals so as not to impair absorption.

With this new insight, science is moving closer to an optimized diet that takes our physical performance and health to the next level. You can also find more on the topic here
