What is Serotonin?

Serotonin is at the heart of our program.

Serotonin (5-hydroxytryptophan) is a neurochemical that occurs in the brain and intestines. It is naturally produced through exercise and eating nutritious foods.

It plays a crucial role in energy and vitality by:

  • regulating sleep
  • strengthening memory and learning
  • influencing social behavior
  • alleviating depression and anxiety
  • moderating and improving mood
  • bringing a sense of liveliness and vitality
What Makes Serotonin Solutions Better?

SeroPro, SeroFit, and SeroDaily are patented blends of natural serotonin, vitamins, and minerals. It contains real 5-HT serotonin—not variants like tryptophan or 5-HTP. Real 5-HT is more effective at delivering serotonin to the brain, which is better at improving your mood and lessening your anxiety.
