                                While L-tyrosine is a non-essential amino acid, meaning the body can produce it, certain medical conditions like phenylketonuria (PKU) can cause a deficiency. If you are deficient in L-tyrosine, it can lead to issues with neurotransmitter production, affecting mood, cognitive function, and overall well-being.
