Life Extension, L-Tryptophan, 500 mg, 90 Veggie Caps5 Reviews
The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width & height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

- Foundation for Longer Life
- Essential Amino Acid for Natural Sleep Enhancement and Stress Reduction
- Dietary Supplement
Serotonin is a neurotransmitter in the brain associated with positive moods and restful sleep. To produce and maintain optimum serotonin levels, your body requires tryptophan, an essential amino acid the body can’t produce.
In the body, tryptophan has been shown to:
- improve sleep
- enhance mood
- modulate stress
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.
Read the entire label and follow the directions carefully prior to use.
Take one (1) capsule 1 to 3 times daily on an empty stomach, or as recommended by a healthcare practitioner. For maximum absorption, take with a small amount of carbohydrate, such as diluted juice. Best if taken separately from protein and amino acids.
Vegetable cellulose (capsule), microcrystalline cellulose, ascorbyl palmitate, silica, medium chain triglycerides.
Store tightly closed in a cool, dry place.
Caution: Consult your healthcare provider before taking this product if you are taking prescription medications (e.g. MAOI and SSRI antidepressants) for depression. Concomitant use of L-tryptophan with antidepressant medications has the potential to increase the risk of serotonin syndrome, characterized by symptoms like confusion, sweating, agitation, nausea, involuntary muscle contractions, and racing heartbeat. Do not use L-tryptophan before driving or operating heavy machinery.
