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.
Tyrosine is an amino acid precursor for synthesis of the neurotransmitters norepinephrine and dopamine. By improving the rate of neurotransmitter synthesis, tyrosine stimulates the central nervous system. It appears to function as an adaptogen by relieving physical symptoms of stress, such as mood swings. Chronically stressed individuals may not efficiently convert phenylalanine to tyrosine, making supplementation with tyrosine desirable.
Tyrosine also serves as a precursor for the thyroid hormone thyroxine and melanin, the pigment responsible for skin and hair color and protection against harmful ultraviolet rays. In addition, tyrosine stimulates growth hormone and is involved in adrenal and pituitary function. Tyrosine is also a powerful antioxidant, scavenging and neutralizing free radicals and inhibiting fat oxidation
