L-Tryptophan

What is L-Tryptophan

Zein Pharma L-Tryptophan provides 500 mg of natural L-tryptophan per capsule, obtained by fermentation. L-tryptophan is an essential amino acid, meaning the body cannot produce it on its own and it must be supplied through the diet.

In the body, amino acids are used to build proteins and can also be converted into other endogenous substances. L-tryptophan is described as a precursor substance that can be converted into serotonin; serotonin can in turn be converted into melatonin in the evening.

Who it is for

This product is for adults who want to supplement their diet with the essential amino acid L-tryptophan, and for those who prefer a vegetarian capsule and a fermentation-based source without animal products.

How to use it

Follow the directions on the product label.

The existing product information notes a consumption example of 2 capsules (1000 mg L-tryptophan) about half an hour before going to bed, and suggests taking it with a carbohydrate-rich snack or drink (such as fruit juice). It also notes that protein-rich meals may reduce uptake into the brain due to competition with other amino acids.

Important information

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

Keep out of reach of young children.

Check the label for allergens, nano-materials and other mandatory product information.
