Final Nine Upbeat 200(1)The 9 Essential Amino Acids

A whole body of evidence.

Protein, the building block of life, is itself made up of 20 amino acids, of which 9 are ‘essential’ which means they can’t be made by the body, but must be brought in through the food and drink we consume.

But not all proteins are equal: some don't have enough of all the essential amino acids to satisfy your body’s needs. This is where Good Whey becomes interesting.

What is whey protein? - whey protein is a remarkable food which naturally contains lots of all 9 of the essential amino acids your body needs every day.

The 9 Essential amino acids which your body can’t make itself:

  • Histidine
  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Threonine
  • Tryptophan
  • Valine


Good Whey protein not only contains all nine essential amino acids, but plenty of them - couldn’t resist reminding you of that. It’s essential!

The ‘Non-essential amino acids’ are made by the body from essential amino acids or in the normal breakdown of proteins:
  • Alanine
  • Asparagine
  • Aspartic acid
  • Glutamic acid
  • Serine

And last but not least, Conditional amino acids are usually non-essential, except in times of illness and stress:

  • Arginine
  • Cysteine
  • Glutamine
  • Glycine
  • Proline
  • Tyrosine

Don't forget the leucine

There’s a lot of leucine in whey protein – good news for Good Whey. The reason that’s good news is that Leucine is the amino acid that kick starts the process of regenerating and building healthy muscles  – a real aid to enjoying an active life. Leucine belongs to a group of amino acids called the branched chain amino acids (BCAAs) that are used by the body as an energy source when it needs to get physical.
