Natural Supplements

Our unique supplement formula empowers the body to fully use the nutrition it receives, regulating appetite and mood and acting as an accelerating factor on weight loss.

The Answer: 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

How It Works

Our program is based on the natural, sustainable, and proven effects of serotonin on weight, mood, and energy.


Proven solutions paired with lifestyle and diet changes to help you lose weight and boost your mood


100% natural with no negative side effects


Positive effects kick in within 1-2 weeks 


Clinically tested & backed by scientific research
