L-Phenylalanine is an essential amino acid, which is the precursor during metabolism for the production of L-Tyrosine and the melanin pigment of the skin.

Dopamine plays an important role in responsible neurotransmission, attention, concentration and motivation, and the lack of dopamine can lead to neurological disorders, depression and memory deficit.

Suitable for vegans and vegetarians

L-Phenylalanine 500 mg

L-phenylalanine is a vital (essential) amino acid that is used in metabolism as a precursor for the production of L-tyrosine and the skin pigment melanin. In addition to its importance for the production of endogenous tissue, L-phenylalanine is particularly important for the production of various messenger substances. In addition to the thyroid hormones, the amino acid is ultimately rebuilt into the neurotransmitters dopamine, epinephrine and norepinephrine. While dopamine is also known as happiness hormone, epinephrine and norepinephrine have an effect on heart rate, blood pressure, alertness, alertness and motivation.

• Essential, proteinogenic amino acid

• From natural sources

• In its natural L-shape

• Suitable for vegetarians and vegans

Why is L-phenylalanine so important

to me?

As a precursor to the formation of the skin pigment melanin, L-phenylalanine contributes indirectly to the protection of our skin from harmful UV radiation and to the formation of a healthy complexion. In addition, L-phenylalanine ultimately forms the coenzyme Q10, which is of essential importance for energy production and protection against free radicals. L-phenylalanine is a precursor of other bioactive molecules, e.g. the semi-essential amino acid tyrosine. In the central nervous system, L-phenylalanine forms various mood-influencing messengers. Similar messengers formed from L-phenylalanine also make crucial contributions to the control of heart rate and blood pressure. Make it easy for your metabolism: The L-phenylalanine capsules of ZeinPharma® contain pure L-phenylalanine, which can be rapidly converted in the body into these important biomolecules.
