An Introduction to L-Tyrosine Dosing
(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.
