Zen Stack Benefits

Keep Calm All Day*

GABA calms the mental chaos by slowing down signals between neurons, making it easier to achieve and maintain a sense of calm.* Our formula contains rosemary to extend GABA’s calming effects for longer.*

Improved Overall Mood*

Provides the nutrients needed to produce serotonin, leading to improved mood from optimal serotonin levels.*

High Absorption and Bioavailability

Vitamin D3 is best absorbed in the body alongside a saturated fat. Natural Stacks includes a coconut oil capsule to ensure the Vitamin D3 gets to where it needs to go!

VITAMIN D3 AND TURMERIC CURCUMIN

Vitamin D3 plays an integral role in regulating the neuromuscular and immune systems, as well as mood and sleep.

It’s also a critical hormone precursor that supports new cell growth and bone formation.

Natural Stacks Liquid Curcumin is 185x more bioavailable than regular powdered curcumin, making it the most efficient supplement for delivering a standard therapeutic dose.

SEROTONIN BRAIN FOOD™ And GABA BRAIN FOOD™

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

Winner of the New Hope Network 2020 Spark Change NEXTY Awards for Best Condition-Specific Supplement!

GABA Brain Food™ is designed to support the normal, healthy production of GABA, a neurotransmitter essential to mental calmness.

The natural compounds in GABA Brain Food™ may help you reduce temporary feelings of stress, as well as promote relaxation and improve sleep quality.

Synergistic Ingredients

Curcumin Liquid Extract (NovaSOL®)

185x more bioavailable than standardized extract

Organic Coconut Oil

The healthiest fat on the planet, organic coconut oil.

Vitamin D3

Vitamin D3 is essential for optimal performance and health.

Gamma-Aminobutyric Acid

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

Grape Seed Extract

Supports healthy cellular function.

L-Citrulline

Found in foods like watermelon, dairy, beef and pork.

Rosemary Leaf Extract

Found in rosemary, sage, mint and basil.

L-Tryptophan

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

Magnesium Glycinate

The magnesium in magnesium glycinate may support relaxation.*


Rhodiola Rosea (root) extract

Rhodiola Rosea is in Serotonin Brain Food because it may support mental well-being and control stress.* With less stress, your brain produces more serotonin.*

Vitamin B3 (Niacinamide)

This formula contains niacin, a form of vitamin B3, because it’s crucial for the overall energy metabolism of the cell. Your cells need it to produce serotonin.*

Zinc Glycinate

Like magnesium, we included zinc in this formula because it is a nutrient cofactor involved in serotonin production.*

Curcumin Liquid Extract (NovaSOL®)

The leading bioavailable clinically-proven curcumin that is 185x more bioavailable than standardized extract. It works by converting the curcumin into a fully water soluble form, thus promoting maximum absorption.

Organic Coconut Oil

We added the healthiest fat on the planet, organic coconut oil to the formula in order to further increase the effectiveness and absorption of the liquid curcumin.

Vitamin D3

Each softgel features 5,000 IU of the most bioavailable form of natural Vitamin D (Cholecalciferol). Vitamin D3 is essential for optimal performance and health.

Gamma-Aminobutyric Acid

Gamma-Aminobutyric Acid is a naturally occurring neurotransmitter with central nervous system (CNS) inhibitory activity. Gamma-aminobutyric acid (GABA), converted from the principal excitatory neurotransmitter glutamate in the brain, plays a role in regulating neuronal excitability by binding to its receptors, GABA-A and GABA-B, and thereby causing ion channel opening, hyperpolarization and eventually inhibition of neurotransmission. GABA acts to slow down signals between neurons, making neurons less electrically excitable.

Grape Seed Extract

Similar to L-citrulline, grape seed extract is used to increase nitric oxide production to help GABA pass across the blood-brain barrier and enter the brain.*

L-Citrulline

An amino acid found in foods like watermelon, dairy, beef and pork. L-Citrulline is converted into L-arginine, a known nitric oxide booster, which is theorized to help shuttle GABA into the brain across the blood-brain barrier.

Rosemary Leaf Extract

Found in rosemary, sage, mint and basil, rosmarinic acid is a naturally occurring polyphenol flavonoid. It is also found in lemon balm and is used in aromatherapy to promote feelings of calm and relaxation.

L-Tryptophan

L-Tryptophan is an essential amino acid that is one of the required nutrients for natural serotonin synthesis.* The most common dietary sources of tryptophan include nuts and seeds, meats and dairy, fish and legumes.

Magnesium Glycinate

Glycine is an amino acid, attached to the magnesium molecule in magnesium glycinate. This is one of the highest quality forms of magnesium available. The magnesium in magnesium glycinate may support relaxation.*

Rhodiola Rosea (root) extract

Used in traditional Chinese medicine for hundreds of years, this well-studied adaptogenic herb supports recovery and may reduce feelings of stress.*

Vitamin B3 (Niacinamide)

Vitamin B-3 (Niacinamide) is an essential vitamin that is also a necessary cofactor for the proper metabolism of fat, carbohydrate, protein, and alcohol.* It’s also closely involved in cell signaling and DNA repair.* It’s used most extensively in the brain, gut and skin, which have a high cellular turnover rate.* Our Vitamin B-3 source is a niacinamide, which has been carefully selected to reduce incidences of flushing - many other Vitamin B-3 sources are niacin, which can cause uncomfortable skin flushing.*

Zinc Glycinate

Zinc glycinate is a critical factor in maintaining a healthy immune system, supporting optimal cell division and replication.* This innovative formula provides natural ingredients from vitamins, minerals, and amino acids that our bodies use as precursors and cofactors to support normal, healthy function of neurotransmitters.*
