What are the Various Effects of L-Tyrosine?
L-Tyrosine has been a multifaceted supplement promoted for applications as different as stress relief to cognitive enhancement for burning of fat to mood enhancement. The effects of L-Tyrosine have been so wide-ranging due to its influence on several brain systems simultaneously. It has been a non-essential amino acid, which is used to manufacture a number of hormones and neurotransmitters inclusive of Dopamine, Norepinephrine, Epinephrine and Thyroxine among several others. While the body could make Tyrosine from Phenylalanine, at times our stores could become depleted. If this occurs, then Tyrosine might become a rate limiting factor in the ongoing synthesis of proteins. It could cause an overall lack of efficiency in both cognitive and physiological processes. What have been some of the most noticeable L-Tyrosine effects as related to stress, brain function, metabolism and more?
As mentioned above, Tyrosine serves as an essential precursor in the synthesis of a number of active substances in the body. For instance, it would be used to make Thyroxin, which has been the body’s main thyroid hormone along with melanin. The Melanin could be described as the pigment, which is responsible for skin and hair color along with providing protection against ultraviolet rays. Typical food sources of L-Tyrosine would be inclusive of fish, soy products, dairy, eggs, poultry, almonds, lima beans, sesame seeds, pumpkin seeds, wheat germ, almonds, oats and bananas. Despite its high prevalence in several foods that we consume, not all of the Tyrosine that you consume has been able to reach the brain.
L-Tyrosine Improves Stress Response
One well-known claim about the effects of L-Tyrosine supplementation has been that it providing protection against the effects of stress. It would not be wrong to suggest that L-Tyrosine affects mood and energy levels. This has been largely due to the role of this supplement in catecholamine production. When you experience stress, your brain would release noradrenaline (norepinephrine) in order to stimulate your CNS along with increasing your energy and mental power. The problem has been that it could take time to replenish various levels of noradrenaline once depleted. This has been, for instance, why so many people feel sluggish and down after the effects of drugs such as Adderall have worn off. Tyrosine has been known to increase the rate of noradrenaline synthesis. The reason for increasing the levels noradrenaline synthesis would be to make you less susceptible to stress and do not experience an energy crash.
