No. Although there are warnings about increased photosensitivity when taking medications containing high doses of St. John's wort, there is little evidence or research to support this effect. Studies have examined St. John's wort preparations containing significantly higher daily doses than serotalin Active Balance Zen Mood¹ (formerly serotalin® HAPPY MOOD), but no increased photosensitivity (phototoxic effect) was confirmed. The St. John's wort content in serotalin Active Balance Zen Mood¹ (formerly serotalin® HAPPY MOOD) is 160 mg per capsule, significantly lower than in the medications mentioned above. This small amount makes increased photosensitivity very unlikely.

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.
Simply dissolve one serving (7.4 g / approx. 2 teaspoons) in 300–400 ml of water, stir well or shake, and enjoy. Ideal before training, in everyday life, or whenever your body needs support.
