View this orderThe 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.
This is the D-Phenylalanine form, not DL, or L form.
D-phenylalanine is a non-protein amino acid related to the essential amino acid L-phenylalanine. D- and L-phenylalanine are structural mirror images of each other. A small amount of D-phenylalanine may be converted to L-phenylalanine in the body. D-phenylalanine is reported to inhibit an enzyme that degrades enkephalins, which are naturally occurring substances in the body that belong to the class of compounds known as "endorphins".
Adult Use: Take 1 capsule daily, without food, or as recommended by a nutritionally-informed physician.
Modified cellulose (vegetarian capsule), cellulose, magnesium stearate (vegetable source).
Caution: Phenylalanine supplements should not be taken by individuals with phenylketonuria (PKU), children, pregnant or lactating women, people with high blood pressure, and anyone taking anti-psychotic medications or MAO inhibitors.
Store in a cool dry place.
