An essential amino acid and precursor to L-Tyrosine which is necessary in the synthesis of proteins and some neurotransmitters
Vegetarian / Vegan
Free-Form
L-Phenylalanine is an essential amino acid that is necessary for the synthesis of proteins. Because L-Phenylalanine can be readily converted into the amino acid tyrosine, which forms part of the structure of the neurotransmittters dopamine and norepinephrine, it is important for the maintenance of a healthy nervous system.

An non-essential amino acid that is involved in protein synthesis
Vegetarian / Vegan
L-Proline is an amino acid that is essential for the synthesis of collagen, the most abundant protein in mammals. Collagen is the main structural protein that constitutes all human connective tissues, including skin, tendons, ligaments, joints, bone, and vasculature (veins and arteries). L-Proline therefore provides building blocks that help to stabilize and strengthen the structural components of the body. Although proline can be made in the body, low protein and vegetarian diets may not provide optimal support for the production of collagen. NOW® L-Proline is 100% vegetarian.

Helps to temporarily promote relaxation.
With synergistic Green Tea (decaffeinated)
Vegetarian / Vegan
L-Theanine is a unique amino acid found naturally in the tea plant (Camellia sinensis). L-Theanine promotes relaxation while maintaining alertness and promotes healthy cognitive function. L-Theanine may also support healthy vascular function through this relaxing effect. Synergistic Green Tea adds the nutrients that are naturally associated with L-Theanine.

Helps to temporarily promote relaxation
With added Inositol and Taurine
Chewable pill format
Sweetened with Xylitol, Sorbitol, and Stevia
Vegetarian / Vegan
L-Theanine promotes relaxation without the drowsiness or negative side effects associated with other calming agents. Chewable format is ideal for those who have trouble swallowing pills. Added inositol and taurine support neurotransmitters that are involved in mental health and function, including relaxation.

Helps in the management of some forms of stress (physical, psychological, sleep deprivation, multitasking, etc.).
Pharmaceutical Grade
L-Tyrosine is a conditionally indispensable amino acid required for the production of the neurotransmitters dopamine, adrenaline, and noradrenaline, as well as for the skin pigment, melanin. Noradrenaline (norepinephrine) and adrenaline (epinephrine) are the main actors in the body’s response to acute stress and, along with dopamine, help to support a positive mood and mental alertness. In addition, L-Tyrosine is especially critical for the normal function of the thyroid gland.
