FAQ - The most important things in brief

How and where is serotalin® YELLOW produced?

serotalin® is carefully manufactured and produced in Germany. The ingredients are tested for heavy metals and pesticides, so you get a product of the highest quality.

Our manufacturing process is GMP certified. This "Good Manufacturing Practice" promises a high standard and guarantee the highest quality.

How does serotalin® YELLOW work?

The hyperforin contained in St. John's wort acts as a reuptake inhibitor of neurotransmitters such as serotonin and norepinephrine, slowing down the breakdown of these important neurotransmitters and naturally increasing serotonin levels. In addition, St. John's wort also has a direct effect on the GABA level in the brain, which contributes significantly to the positive and unique effect of St. John's wort extracts.

For the selection of a suitable additive plant extract, we investigated a variety of extracts as well as single substances with calming effects. As an optimal ingredient and companion we identified the aqueous flower extract of the littleleaf linden (Tilia cordata), which is added to St. John's wort with a high-quality extraction ratio of 10:1.

These two main ingredients together with L-tryptophan and co-factors make the serotalin® St. John's wort edition an ideal companion.

How does serotalin® YELLOW differ from serotalin® ORIGINAL?

While serotalin® ORIGINAL has a strong effect on the drive and motivation, the effect of serotalin® YELLOW lies in the calming and composure.

The positive effects of St. John's wort have been known since the Middle Ages. In combination with the amino acid tryptophan and with valuable co-factors such as riboflavin 5-phosphate (vitamin B2), the building materials for a higher serotonin, dopamine and GABA levels with a calming effect are created.

Thus serotalin® YELLOW additionally protects the cells from oxidative stress, supports the energy metabolism and the nervous system and contributes to the reduction of fatigue.

Is serotalin® YELLOW addictive?


How is serotalin® YELLOW consumed?

Adults consume 1 capsule daily in the morning with sufficient water.

Ich schlafe endlich schneller ein

Das Spray wirkt super und es schmeckt auch noch. Due Kapseln bestelle ich ebenfalls bereits zum zweiten Mal. Ich fühle mich damit ausgeglichener

Kathrin Eisold

Hab mir nach Serotonin, nun auch mal Serotalin Yellow bestellt. Ich bin wieder beeindruckt und überrascht, es " dämpft" mich, ohne mich zu dämpfen. Ich nehme die Probleme nicht mehr so sehr psych. an. Kann also mit dem Alltag besser umgehen, schlafe besser.

Top Service, Schnelle Lieferung und ich bin super glücklich mit der Wirkung

Mir tun die „Happy Pills“ einfach nur gut. Bei einer Lieferung ging was schief und der Service war aber dann wirklich super und mega unkompliziert. Absolut empfehlen

Fühle mich besser

Ich habe mir die YELLOW und ORANGE Kapseln bestellt, weil ich in den letzten Monaten unter extremem Stress stand und merkte wie meine Stimmung darunter sehr litt und ich auch privat immer unleidlicher wurde. Seit ich beides nehme, bin ich tatsächlich ausgeglichener, empfinde mich als weniger gestresst und fühle mich wohl.

Weniger Nervosität und besserer Schlaf

Ich fühle mich tagsüber belastbarer und gelassener. Auch der Schlaf ist ruhiger.

You meditate regularly, do sports and generally try to live a healthy and balanced life. Still you can't switch off completely? Sometimes important issues just won't let us go. It doesn't matter whether it's a job, private life or something similar - there are so many things that can give you inner restlessness and a bad mood.

St. John's wort capsules - what is St. John's wort?

St. John's wort has been valued for its positive effects for many centuries. Only a few years ago, the yellow-flowering herb was even voted medicinal plant of the year. Nicknamed the "captured power of the sun" , it is partly due to its bright yellow flowers, which open from June and add a few fabulous splashes of color to wild meadows and embankments. As soon as the medicinal plant blooms, it can be harvested. Leaves, flowers and shoots are harvested to get their positive effect. You don't even have to start looking - we've done it for you. Our St. John's wort capsules contain effective extracts that release their effects in your body. For the best result, you should take the capsules regularly and without a break. Then the natural powers of the medicinal plant can develop optimally.
But how does St. John's wort work? The extracts from the plant in our St. John's wort capsules help against mild depressive moods and calm the mind. This is ensured by the hyperforin contained in the leaves and flowers. This is a reuptake inhibitor of serotonin, dopamine and GABA. These are neurotransmitters that perform different tasks in your brain:

  • Among other things, GABA is responsible for your mental relaxation.
  • Dopamine has a motivating, stimulating effect.
  • Serotonin is important for many bodily functions. It regulates special messengers and moods in your brain.

If you take in hyperforin, after the release of serotonin and co. it inhibits their renewed (too rapid) re-absorption in the respective transmitter cells.

That means: If you take our St. John's Wort capsules regularly, your happiness will get a real boost.

St. John's wort capsules - herbal effect for the soul

You take all of these ingredients with the serotalin® YELLOW St. John's wort capsules every day. The capsules contain no additives and are easy to dose. The positive effect is of natural origin, since the ingredients support and stimulate normal processes in your organism.

St. John's wort for depression? A natural companion on your way!

St. John's wort is particularly well-known for its effects on mild depression. As a serotonin reuptake inhibitor, it builds a longer-lasting feeling of happiness. St. John's wort is therefore known as a natural antidepressant. In the last few centuries it has developed into a true miracle cure, straight from nature into the medicine cabinets of many people. No wonder - after all, St. John's wort extracts have a much gentler effect on the body than synthetic psychotropic drugs. There are some scientific studies on the positive effects of the medicinal herb in our St. John's wort capsules. The advantage over many synthetic agents is the gentle effect. Many antidepressants have side effects that are sometimes stressful, such as tiredness or lack of concentration. St. John's wort, on the other hand, as a natural active ingredient, has hardly any side effects and can usually be taken without hesitation.
There are many things in life that trigger periods of depression. In addition to overexertion and lack of light or sun, this can also be bereavement or genetic predisposition. No matter what takes the wind out of your sails - don't let it get you down. With our St. John's wort capsules, you can take your happiness back into your own hands and turn the sails towards happiness again.

winter blues? He can stay outside!

Are you a winter or a summer type? Many people like the bright colors in autumn - but everything that comes after is stressful. Winter brings wet, cold and above all darkness. That in particular can cause us humans a lot of trouble. Because sunlight is a true source of energy and makes us happy. This is because serotonin production is stimulated as soon as the sun's warm rays hit our face. In December or January it can happen that the clouds do not leave a spot for the sun for many days at a time. A typical episode? Winter blues or winter depression.
Due to the lower serotonin production, mood sinks and fatigue increases. We are more prone to stress and physical illness. Motivation, where are you? If everyday life then means additional stress, it can be quite demanding for body and soul.
Treat yourself to your own personal time in the sun and leave the darkness outside the door in the cold. The St. John's wort capsules help you with this and support the feeling of happiness through their reabsorption-inhibiting function. Order your reinforcements for the whole winter straight away: You can get our St. John's wort capsules in a practical storage pack. 60 St. John's wort capsules provide you with calming powers and mood-enhancing St. John's wort for 2 months.
