Tyrosine: Antidepressant, Stimulant & Adaptogen:
Tyrosine is an amino acid that acts as a precursor molecule to Dopamine, Norepinephrine, Epinephrine and Thyroid hormone. All of these substances help to keep us active, cheerful and wakeful, but when they are at low levels, we all sing the blues. Due to its ability to increase the amounts of the previous substances it is useful in the treatment of depression, stress, narcolepsy and cocaine addiction.
Like all amino acids, it is best absorbed on an empty stomach in the presence of a carbohydrate (like orange juice). This is due to competition from other amino acids that would be present in a protein meal. However, due to its stimulatory effects, it is best taken in the morning and at noon.
Nutraceuticals such as vitamins, amino acids, herbs and minerals, help to enable biological processes to occur. Pharmaceuticals on the other hand stop certain processes from occurring. Almost like 2 sides of a coin.
The dose that l-tyrosine is normally taken in clinical practice ranges from 500-1000mg, twice per day, on an empty stomach, with a carbohydrate to help absorption. Yet, a word of caution is in order. If your doctor has you on anti-depressant medications or levo-dopa (which is a Parkinson’s disease drug), you should not take l-tyrosine. In addition, vitamin B6 taken too close to it will inactivate it’s affects.
