The package contains 200 g of powder, i.e. 666 servings, so with the recommended use – one serving a day – one package lasts a very long time. The powder is unflavoured and contains no fillers, sweeteners or flavourings. The powder form suits those who find swallowing tablets uncomfortable, as a serving can simply be mixed with water or juice.

What is L-tryptophan?

L-tryptophan is an organic compound belonging to the protein-building amino acids. It is an essential amino acid: the body is unable to synthesise it on its own, so it must be obtained from daily food or from food supplements. Sources of tryptophan include meat, dairy products and seafood, as well as pumpkin seeds, avocados, legumes, bananas and flaxseed. According to the manufacturer, tryptophan is poorly soluble and has a slightly bitter aftertaste – this is a natural feature of the raw material. That is why it is most convenient to mix the powder with a small amount of liquid or to drink it directly with water or juice.

How to use?

Mix one serving, i.e. 300 mg (one level scoop), with 100 ml of water or juice. Take one serving a day, preferably before bedtime. Use the 0.5 ml scoop included in the package to measure the serving. One serving is also the recommended daily dose, which must not be exceeded. As the powder is poorly soluble and has a bitter aftertaste, mix it gently with water or juice, or drink the powder directly with water or juice.
