Key Ingredients

L-Tryptophan

We included this ingredient because it’s the precursor for serotonin. Your brain needs adequate levels of L-tryptophan to produce serotonin.*

The magnesium in magnesium glycinate may support relaxation.*

Gamma-Aminobutyric Acid

As the main inhibitory neurotransmitter in the brain, GABA’s role is to act like a “brake” and balance excessive stimulation.

Other Ingredients Include:

Rhodiola Rosea (root) extract
Niacin
Zinc Glycinate
Grape Seed Extract
L-Citrulline
Rosemary Leaf Extract

What To Expect

"I wasn’t sure if this would work but I decided to give it a shot… and wow! It has made such a massive difference for me. My mood has improved so much, even just overall. I feel a lot happier and less stressed daily than I did before taking these. I’ve taken these now for about 2 months straight and I will never go without them again!"

- Corissa V.

"I haven’t felt this rested in years. I have several sleep issues, but most medications make me drowsy the next day. The GABA lets me sleep soundly and wake up feeling rested."

- Marion B.

"This is an amazing product. I was taking it for a while and then stopped. Immediately I felt my sleep pattern was off. I ordered it again and now feeling balanced throughout the day and my sleep pattern is getting better."
