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

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.*
