Healthy Visual Function* Taurine is a conditionally essential amino acid which is not utilized for protein synthesis, but is mainly found free in most tissues, especially throughout the nervous system.* It functions in tissues by stabilizing cell membranes, aiding the transport of potassium, sodium,...

Encourages Positive Mood* Promotes Restful Sleep* L-Tryptophan is an essential amino acid; therefore, it is not synthesized by the body and must be obtained from the diet.* L-Tryptophan is critical for the production of serotonin and melatonin, which help to support a positive mood,...

Healthy Immune System Function* Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with other amino acids to rid the body of ammonia, a byproduct of protein metabolism.* Citrulline also plays an important role in the...

Supports a Positive Mood* With Glycine, Taurine & Inositol 5-HTP, the intermediate metabolite between the amino acid tryptophan and serotonin, is extracted from the seed of an African plant (Griffonia simplicifolia). NOW® Double Strength 5-HTP has twice the 5-HTP (200 mg per capsule) as...

Free Radical Neutralizer* Reduced Active Form* Glutathione is a small peptide molecule composed of three amino acids: cysteine, glutamic acid, and glycine. It is produced by every cell of the body, with especially high levels in the liver.* Glutathione is critical for healthy immune...

Promotes Relaxation* Healthy Vascular Function* With Inositol Theanine is a unique amino acid found naturally in the tea plant (Camellia sinensis). Theanine promotes relaxation while maintaining alertness and promotes healthy cognitive function.* Theanine may also support healthy vascular function through this relaxing effect.* This...
