An Introduction to L-Tyrosine Dosing
L-tyrosine (also known just as
tyrosine) is an amino acid sometimes used in
dietary supplements. It is important to note that unlike medications, for which the standard doses have been well established, less information is available for determining the best dose for supplements, including L-tyrosine. Since L-
tyrosine supplements have not been extensively studied in humans, a safe and effective L-tyrosine dose has not yet been established for any use.
What Is a Reasonable L-Tyrosine Dose?
Since there is little strong evidence to guide you in your choice of an L-
tyrosine dosage, a good plan is to start with a reasonable dose (the recommended starting dose on the label of your L-tyrosine product, or perhaps a little less) and see how your body reacts to that dose. If it seems to be working a little, but not quite well enough, perhaps a higher dose (but not more than recommended on the label) would be right for you. If you find that you are experiencing
L-tyrosine side effects, perhaps a lower dose would be better. As mentioned, a maximum safe L-tyrosine dose has not been established.
If you have phenylketonuria (PKU), you should not take any L-tyrosine supplements without your healthcare provider's approval and supervision. People with this condition must closely regulate and balance their intake of amino acids, including L-tyrosine.
General Information on Dosing With L-Tyrosine
Some considerations for people taking L-tyrosine include the following:
- Since the manufacturing of supplements such as L-tyrosine is not closely regulated, it is important to choose a trustworthy manufacturer of your L-tyrosine supplements. It is a good idea to look for the "USP" symbol, since this means that the supplement has been tested and contains the right ingredients in the right amounts.
- If you have any chronic health problems or take any prescription medications, you should check with your healthcare provider before taking L-tyrosine.
- If you are unsure about anything related to your dosage or L-tyrosine dosing in general, please talk with your healthcare provider.
