As you may already know, l-tyrosine amino acid is crucial to maintain the health of an endocrine system, since it serves as a precursor of different hormones including the ones synthesized in adrenals, neurotransmitters (e.g. dopamine) and furthermore such important hormones as melatonin and thyroxine. And Now Foods, as usual, provide this great formula of l-tyrosine with an adequate dosage and high quality. Def recommend this one, especially to people with hormonal disorders such as adrenal insufficiency, hypothyroidism, and etc. P.S. don’t forget to ✨thumbzzz upp✨ if you like my review

UPDATE : A little over 3 months I took 2-3 tablets a day. My TSH values decreased to 0.77 /before was more that 5!/, as well as anti-TPO hormones now are lower. Be careful not to overdose, at very high doses you get a slight headache. --------- I have subclinical hypothyroidism, i.e. my TSH hormone levels are elevated, but t3 and t4 are normal. I decided to take 3 capsules 30 minutes before meals a day. In 3 months I will do my research again and I will complete my review of whether the product is worth it Since I drink it I feel good, it is very suitable for intense mental activity and work under stress.

I work 12 hour shift nights at my local police department, I have to be alert and vigilant EVERYDAY. I'm also a mother to 2 very! active pre teen sports player boys. I get little sleep on most days. I started taken L-Tyrosine to help me stay energized. I can tell you this helped me 100% . on days I do get to sleep this does no effect me going to sleep I sleep like a baby! it also helped me focus better on my job.

I've been taking 500 mg L tyrosine for several years at bedtime and it still works perfectly. I don't take any other neurotransmitters with it. I do exercise several days a week at a gym for about 45 minutes for good health and social interaction and I believe it is this combination that keeps me mentally and physically fit. I am 81 yrs old.

Works well to help with physical side effects of ADHD medication. No more headaches, acid reflux, jittery come-up and tingly comedown, much less dry mouth throughout the day. Appetite is back by about 70%, it's nice to be excited about food again and actually be able to chew and swallow it as there is more saliva in your mouth. All this without curbing the cognitive benefits of the meds. This and Magnesium Biglycinate have been lifesavers when it comes to cancelling out side effects

I bought to improve energy and mood. Benefits thyroid. Size is medium and easy to swallow. Taste is neutral. High quality supplement. Comparing to other supplements I noticed a greater effect from this l tyrosine. It significantly reduced my appetite so it was easier to stick to healthier diet. Aslo great supplement for training.

I was quite sceptical about this supplement but the idea sounded cool so the wife and I decided to give it a shot. The pill is a typical capsule in a typical plastic bottle. After a few days of taking it, my wife reported that she has vivid dreams and discontinued taking it as it impacted the quality of her sleep. I on the other hand fall asleep as soon as my head hits the pillow and sleep till morning. Did not notice any other changes. I don't know if it's good for you or not but it does something and seems to affect sleeping patterns.

My psychiatrist recommended this supplement to help my brain produce dopamine. I have really bad ADHD and take meds for it but they have been kinda not helping lately as much and this was recommended to help. I feel like it’s helping with energy and focus. I don’t take this for bodybuilding or muscle training or anything else. I feel benefits from this and the brand is trustworthy and has high quality ingredients and good value for the size of the package.

L-Tyrosine has many benefits and is generally safe, but be aware that L-Tyrosine can increase your thyroid hormones. So if you’re hyperthyroid you should use caution when supplementing with L-Tyrosine because it may change the way your thyroid meds work. And if you’re taking MAO inhibitors (MAOI’s) like selegiline, Azilect, Marplan or Nardil you should not use L-Tyrosine. It can be very dangerous!

I have elevated TSH levels and I also started to have grey hair (I am only 30 so it's definitely not normal) and I recently found out that tyrosine is the precursor of thyroid hormones and also of melanin (the pigment that gives hair it's dark colour). Also, when your cortisol levels are high, the body uses up a lot of tyrosine, so if you are stressed you definitely could use some. I have only been taking this for a month but I can already say I feel better (my energy was low because of my hypothyroidism) and I hope the problem with my hair will go away as well. I will write an update in a few months to let you know if it helped with my TSH levels and if I still have new gray hair, but I have a good feeling about this. Hope this review helped, stay healthy guys!
