Source Naturals L-Tyrosine Free Form -- 500 mg - 50 Tablets
Less effective than others
Way less effective than another brand I used to take- Could be related to the form - these are tablets while I used to take the other brand (same dosage) in capsules , they clearly don't absorb well for me - effects are mild at best , even at double the dose, and don't last long. Buy your tyrosine pure in capsules or powder - makes a world of difference. I don't recommend these.

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, special peptides which subdue messages of physical discomfort. L-Tyrosine is also a precursor of the protective skin pigment melanin.
