My son who has adhd takes this amino acid daily. This product is very good quality and has no additives and dissolves easily into any drink. We agree that it aids / boots his alertness concentration and assist with depression and it works on dopamine levels. My son uses this when he is at school and work.
I have problems with sleeping and taking it on an empty stomach after a bad night's sleep, it gives me incredible amount of energy and totally negates the effect of lack of sleep for most of the day (I start feeling sleepy only around 5pm). As it increases dopamine (low level of dopamine can cause depression) it also improves mood and motivation which comes as an extra bonus. :) Another plus is that it dissolves really well in water.
L-Tyrosine is a free-form amino acid which rapidly crosses the blood-brain barrier. It is a precursor for the neurotransmitters dopamine, norepinephrine and epinephrine, as well as for thyroid hormones and enkephalins, important peptides ease messages of physical discomfort. L-Tyrosine is also a constituent of amino sugars (glycosaminoglycans), which play a role in numerous biological functions.
The substance is involved in lipid metabolism, regulates appetite, improves melanin synthesis, normalizes the functioning of the adrenal glands, pituitary gland, and thyroid gland. I took for the thyroid gland and adrenal glands. I chose the powder form, because. it is more profitable and more convenient to receive. The capsule must be opened, and then immediately from a spoon under the tongue. By the way, my dosage is 1/3 teaspoon. Excellent in combination with iodine and selenium reduces TSH. It also helps the adrenal glands. I highly recommend. Great shape.
Pure powder, no fillers- love it! 1/4 tsp is 660 mg, it's big saving. I give it to my mom mornings in a glass of water. It doesn't dissolve completely but has no taste. It is easy to choose needed dosage especially if you know how to perform muscle testing. Tyrosine is amino acid needed by thyroid to produce hormones.Like it if it's helpful,please
