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

Do not be fooled!

There are manufacturers whose preparations contain both the D and the L form of phenylalanine. In nature, however, only the L-form of the amino acid occurs as a protein component. The D-form of phenylalanine, on the other hand, can only be obtained synthetically. As we know today, our body cannot utilise D-phenylalanine. A positive effect of DL-phenylalanine preparations is therefore more than questionable. L-phenylalanine, on the other hand, is found in each of our body cells. With our product you play it safe: count on L-phenylalanine capsules of ZeinPharma®, which contain 100% of the L-form in high purity.

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.

5 reasons why preferring L-Phenylalanine from Zeinpharma®

• 100% L-phenylalanine

• High purity

• Extremely valuable as a precursor to many of the body's own bioactive substances

• Optimal bioavailability with only 3 capsules per day

• Of pure vegetable origin, therefore ideally suitable for vegetarians
