If you are a regular user of pre-workouts, then you have likely encountered the ingredient L-Tyrosine. At first, you probably wondered what it was, but as time went by, you just accepted it as an ingredient. Next to good old-fashioned caffeine as an active ingredient in most pre-workouts, you will almost certainly find L-Tyrosine. Today, we are going to answer the question: what is L-Tyrosine?
Also known as tyrosine, it’s an amino acid found in dairy products, meat, nuts, beans, and other high protein foods. L-Tyrosine helps you produce adrenaline and dopamine. These two hormones help reduce stress when you are in certain high-stress situations.
The rationale is, if you’re doing something stressful – such as a high-intensity workout – your focus and mental clarity may be improved with the presence of L-Tyrosine. Additionally, if you are more focused, you are less fatigued and that translates into improved endurance.
In a well-known 1995 study, participants were required to stay awake all night. During this time frame, they did nine iterations of performance tasks for thirteen hours straight. After six hours through this test, half the participants took tyrosine. These participants showed increased vigilance and a significant improvement rather than the usual decline one would expect.
Another study involved cold. Eight males were tasked with performing a memory-based computer task similar to the game Memory. They had to perform the task in 39 degrees Fahrenheit. Those taking tyrosine performed significantly better.
To get the full advantage of L-Tyrosine’s performance enhancements, it is best to take it 15 to 30 minutes before exercising. Pre-workouts containing L-Tyrosine should be taken with water. The most effective dosages are 500mg to 2000mg per serving.
L-Tyrosine begins to take effect as soon as it enters the bloodstream. Typically, 15 to 30 minutes after consumption. Consistent use, in combination with a sensible diet, will help users experience the full effects of L-Tyrosine.
At this time, there are no studies linking supplements containing L-Tyrosine to any significant side effects. However, be conservative and do not take a very large dose at one time as it may cause an upset stomach.
