Product Description


Tyrosine is an amino acid that is naturally produced in the body from another amino acid, called phenylalanine. It is found in numerous foods, mainly cheeses, where it was also discovered for the first time. The word "tyros" is supposed to mean "cheese" in Ancient Greek. It can also be found in chicken, turkey, fish, dairy products, and most other foods with a high quantity of protein. Vegetarians, vegans, and persons on severe diets or low-protein diets usually suffer from tyrosine deficiency, which is why it makes sense to supplement it.

Tyrosine is essential for the production of numerous important substances in your body.

Dopamine manages your reward and pleasure center. This important brain chemical is also crucial to improve your memory and motor skills.

Adrenaline is a hormone responsible for the stress response. Adrenaline prepares the body for the "fight or flight" response when facing danger or injury. This allows the body to better prepare for the stressful situation. It is especially noticeable in sport and in combination with caffeine when the motivation and focus merge with the "sensation of happiness" and improve your athletic performance.

Thyroid hormones are produced by the thyroid gland and are primarily responsible to manage your metabolism. Tyrosine deficiency may lead to irregular function of the thyroid gland.

Melanin is the pigment that gives color to your skin, hair, and eyes. Tyrosine deficiency may lead to paleness and unhealthy-looking skin.

Tyrosine is extremely efficient when you're under stress. Stress may negatively impact your thought process, memory, alertness, and knowledge by reducing the number of available neurotransmitters. Extreme temperatures, fear, pressure, and psychological pain may weaken your memory because they lead to a reduction in the number of neurotransmitters. Tyrosine may prevent the decrease in the number of neurotransmitters and restore cognitive abilities.

Tyrosine may also help you to improve your cognitive flexibility when you find yourself in a difficult position.

If we draw the line, we can say that tyrosine, especially in Swanson's excellently-bioavailable acetyl form, is a very interesting dietary supplement that can significantly improve your quality of life.
