What are amino acids?

Amino acids are the building blocks of protein, which helps to grow and maintain muscle mass.² This is a great support for all fitness goals, as maintaining your muscles is super-important to progress - whether you are looking to bulk up or slim down.

What are essential amino acids?

Essential amino acids can be defined as amino acids that your body needs, but can't produce itself. There are nine different essential amino acids in total, these include: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

All nine essential amino acids have to be obtained through your diet, with the most common sources being meat, poultry, and eggs. This can make it challenging for those following a plant-based lifestyle to get enough of these amino acids from their food alone.
