Thorne Research, L-Tyrosine, 90 Veggie Caps14 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.

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

iHerb Customer Reviews
Provides a noticeable mood boost. This is a must for anyone with thyroid/adrenal issues. One of the few supplements that actually works. Don't overdo it though. I've found that one capsule taken first thing in the morning on an empty stomach (1 hour before eating anything) is all I need. There is another product from Thorne called Thyrocsin which has l-tyrosine in it, but it was impossible for me to take it on an empty stomach due to nausea from some of the other ingredients.
L-Tyrosine,is a precursor to Dopamine a major neurotransmitter in the brain. Thorne is a brand I trust as it has no harmful excipients.
