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.
5-HTP (L-5-Hydroxytryptophan) is an intermediate in the natural conversion of the essential amino acid, tryptophan to serotonin, a brain chemical associated with positive mood and well-being. Preclinical studies show that 5-HTP may help support healthy levels of serotonin in the body. In addition to a balanced mood, serotonin may also support melatonin production and a healthy sleep cycle. Serene Science® 5-HTP is derived from the seeds of the African plant Griffonia simplicifolia.
1 to 2 capsules once or twice daily with meals, or as directed by your healthcare professional.
Microcrystalline cellulose, gelatin (capsule), silica, and magnesium stearate.
Not for use by children, pregnant or breastfeeding women. If you are taking antidepressants, SSRIs, MAOIs, sedatives, painkillers, or other drugs, or if you have any medical condition, consult your physician before taking 5-HTP. In some people, temporary nausea, diarrhea, or abdominal discomfort may occur. If these symptoms occur, lower the dose, or spread the dose throughout the day. Discontinue use if any of these symptoms persist for more than three days. May cause drowsiness; do not drive or operate heavy machinery until you know how 5-HTP affects you.
Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.
