The World’s First Open-Source Supplement Company

Most companies use "proprietary blends" so they don't have to tell you the amount of each ingredient in their formulas. At Natural Stacks we believe it's your right to know exactly what you're putting into your body. We proudly publish our innovative formulas and ingredient suppliers in an open source format. 

LEARN ABOUT OUR COMMITMENT TO TRANSPARENCY

01/ How Serotonin Brain Food Works

Serotonin Brain Food™ is designed to support the body's natural production of serotonin, a neurotransmitter essential to mental well-being.

  • Supports a positive mood†
  • Maintains healthy appetite & digestion†
  • Promotes calmness & sense of well-being†
  • Relieves stress & frustration†

This natural formula contains the precursors and cofactors required for healthy serotonin metabolism.

By providing your body the nutrients it needs to metabolize these neurotransmitters, it is able to achieve optimal levels naturally. 

This method of naturally finding optimal levels also removes the chance of habituation or down-regulation, so you can safely take our Brain Foods to achieve and maintain optimal levels of Serotonin for long-term use

Amazing supplement LOVE the Serotonin!!

This supplement has been a major game changer for me. I’ve been using for over 2 years now and hope I am never without! I sleep better, much more calm and focused and not bothered by the “little” stuff anymore. Normal antidepressants made me lethargic and made me gain weight. This is just the correct amount of “happy” to make my life manageable without prescription meds! LOVE love love this product!

So far, I am impressed!

This is the third day of taking 3 capsules of serotonin and I am already feeling a change in mood. Typically, it takes awhile for supplements to load in the system for optimal results. I am sensitive to anything I put in my body and usually can tell if a product will be a good fit for me within the first week. So far I am pleased. My second review and recommendation to follow after more time has passed.
