Optimized Tryptophan Plus

90 vegetarian capsules

Item Catalog Number: 01721

NON GMO ProductSerotonin is a neurotransmitter in the brain associated with positive moods and restful sleep.1-4 To produce and maintain optimum serotonin levels, your body requires tryptophan, an essential amino acid the body can’t produce.1

In the body, tryptophan has been shown to improve sleep,3,4 enhance mood,1,2,4 and modulate stress.5 So Life Extension offers Optimized Tryptophan Plus to broadly and powerfully support tryptophan levels already within the normal range.

The basis for this formula is premium L-tryptophan, which has undergone significantly more rigorous manufacturing processes than regular tryptophan material to assure the highest purity and safety.

In addition to an optimum amount of premium tryptophan … this formula also provides a unique, balanced supply of other nutrients found to help maintain tryptophan activity in the body.6-8 Those nutrients include lysine, niacinamide, and extracts of hops and rosemary to provide nutritive support for the body’s production of serotonin.

Caution

Serotonin syndrome is characterized by high levels of serotonin and symptoms like confusion, sweating, agitation, nausea, involuntary muscle contractions, and racing heartbeat. Do not take L-tryptophan if you experience these symptoms.
