Pure Encapsulations - L-Tyrosine 500mg - Amino Acid Supplement - 90 Vegetarian Capsules

Pure Encapsulations is one of the best brands on the market. Only high-quality ingredients in the products. This supplement has only one ingredient L-Tyrosine, no additives. I bought Pure Encapsulations L-Tyrosine on the recommendation of my endocrinologist, because I cannot take the thyroxine, which gives me insomnia. For this reason, the endocrinologist recommended trying this supplement. After I took one capsule of Pure Encapsulations L-Tyrosine in the morning with breakfast, I found out that the dosage of 500 mg also gives me insomnia, so I divide the capsule in half and take half, this does not give me insomnia. Later I will try to take the whole capsule, will update review later. I can't say whether this supplement will help me lower my TSH, I haven't had any tests yet.
