Synergistic Ingredients


L-Tryptophan may help promote restful sleep, calm and relaxation.

Magnesium Glycinate

One of the best-absorbed forms of magnesium.

Supplier: AIDP

Rhodiola Rosea (root) extract

Standardized to 3% total Rosavins, 1% Salidroside

Vitamin B3 (Niacinamide)

Our Vitamin B-3 source is a niacinamide, which has been carefully selected to reduce incidences of flushing.

Zinc Glycinate

This innovative formula provides natural ingredients from vitamins, minerals, and amino acids

Lactobacillus Helveticus (2.7 Billion CFU)

Supports gut bacteria associated with positive mood states*.

Lactobacillus Brevis (1 Billion CFU)

This unique strain is known to increase levels of the all-star
brain growth hormone.


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

Magnesium and glycine both have a calming effect on the brain, helping to reduce neural excitability (stress) and support healthy sleep quality.* Magnesium glycinate is one of the best absorbed forms of magnesium.

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.*

Lactobacillus Helveticus (2.7 Billion CFU)

Daily use of this strain has been shown to support gut bacteria associated
with positive mood states. The cultures accomplish this by relieving stress-related
gut inflammation and increasing production of calming neurotransmitters
in the gut to support a positive mood and relieve stress*.

Lactobacillus Brevis (1 Billion CFU)

This unique strain is known to increase levels of the all-star
brain growth hormone, brain-derived neurotrophic factor (BDNF).
Higher levels of BDNF are associated with increased intelligence,
positive mood, productivity, memory, as well as a decreased risk
of various neurodegenerative mental states*.
