Unfortunately, the product did not come with a leaflet. There was no information on the tin about the origin and quality (food or pharmaceutical quality) of the main ingredient. We would like to see "more" here".

I have been taking L-tryptophan for a long time because I personally feel that it is good for me. The capsules are easy to take and easy to swallow.

I ordered the product to provide my body with the necessary building blocks for serotonin and melatonin. The capsules are vegan, high-dose, easy to swallow, odourless and tasteless. Product design: The tin has a sticker of a starry sky to promote sleep through the sleep hormone melatonin. So I know directly which of the tins contains L-T. Overall, I like both the product and the design very much.

Very affordable and very good quality
