FAQ - Answers to your questions

At serotalin, we set high standards for the development of our products. Our formulations are based on scientific findings and are developed in close collaboration with the BioPark in Regensburg, using the most innovative technologies. By applying in-silico simulation, we determine the efficacy of our active ingredient formulations using computer-aided testing before they even enter production.

Serotalin products are not only developed but also manufactured in Germany. This allows us to guarantee the highest quality, whereas with other manufacturers, the country of origin and quality standards are not always known.

Our products are, of course, subject to regular testing by independent German laboratories. From development to production to laboratory testing, everything takes place in Germany.

The effects of caffeine can vary greatly from person to person. Coffee intolerance can also be related to other ingredients found in coffee, such as chlorogenic acid, polyphenols, or trigonelline. Because our supplements may contain additional active ingredients, the effect of the caffeine may be different than that of a cup of coffee. We have already received several reports that they tolerate the capsules well, unlike their usual coffee.

If you are unsure about tolerability and before taking any dietary supplements, always talk to your doctor.

In principle, our products can be combined. However, if you are taking multiple products containing caffeine or Griffonia seeds, we recommend staggering the intake. We recommend always trying the products independently of each other first.

Please consult your doctor or alternative practitioner before taking or combining dietary supplements.

Our serotalin melatonin spray is non-addictive, as it is quickly broken down by the body. However, we don't see it as a long-term solution. serotalin melatonin spray helps you fall asleep faster on stressful days, during shift work, or when suffering from jet lag, and thus be more energetic the next day.

The liposomal melatonin contained in the product enables higher bioavailability and better absorption of the melatonin. This is because in a liposomal formulation, the melatonin is encapsulated in so-called liposomes, which consist primarily of lipids, and is administered to the body in this way. The liposome prevents the melatonin from being broken down, for example, by saliva before it can enter the body, which would reduce its effectiveness.

Because Serotalin Melatonin Spray is sprayed into the mouth, it can be absorbed directly through the mucous membranes. This results in a faster onset of action, helping you fall asleep faster.
