Reviews
According to several studies L-Tyrosine helps make important substances in the body, such as Dopamine, a brain chemical which aids memory and motor skills, and Adrenaline, which is the hormone responsible for the 'fight or flight' response. Tyrosine can also help regulate metabolism via the thyroid gland. There are loads more benefits of which studies have been done, just do a Google search to see what an advantageous supplement it is to take. I am taking this supplement in conjunction with 5HTP (serotonin) as serotonin is said to deplete Dopamine and I want to get the 2 amino acids in the right balance. I have only been taking Tyrosine for a short time, so a little early to give an assessment of it's effect, however, I do experience a slight 'boost' after taking it first thing in the morning on an empty stomach, which makes getting ready for the day much easier. Does not contain fillers and binders, so seems very pure, plus consisting of 120 capsules at 500mg per capsule, is good value in my opinion.
L-tyrosine is a nonessential amino acid (protein building block) that the body synthesises from phenylalanine, another amino acid. Tyrosine is essential to the structure of almost all proteins in the body. It is also the precursor of several neurotransmitters, including L-dopa, dopamine, norepinephrine, and epinephrine. L-tyrosine has been getting much buzz for claims that it can help with stress and memory.
I was recommended trying this to help with ADHD and so far I have noticed a difference in my fight or flight in anxious moments...I've been taking this for about a week and yes I am happy so far. The difference is subtle and I am considering the higher dosage of two a day instead of just the one. Overall yes I will buy again.
I periodically take L-Tyrosine to help support the adrenal glands. 500mg per capsule is fairly standard and this packet contains 120. This is very competitive and good value. Would recommend.
These are large tablets but can be easily taken with liquid . The box is very slim and so this is easy to store and easy to find.
