Tyrosine · 120 capsules

The amino acid L-tyrosine is involved in numerous bodily functions and, as a starting substance for the synthesis of all catecholamines (L-DOPA, dopamine, adrenaline, noradrenaline etc.) and thyroid hormones, is often supplemented as a "dietary amino acid" and before training.

Tyrosine is enriched with a vitamin B complex, which helps to reduce symptoms of fatigue, among other things.

What can I expect from tyrosine?

The amino acid tyrosine can be an effective support for you on nutrient-reduced diets, as it has the property of maintaining the synthesis of important hormones and neurotransmitters (thyroid hormones, catecholamines). For this reason, you can also supplement tyrosine excellently in combination with caffeine before training. The B vitamins also play a supporting role here, helping to ensure that you suffer less from symptoms of fatigue and that your energy metabolism functions normally.

However, the overall effects of supplementing with tyrosine depend very much on your exercise, your eating habits and the use of supplementary supplements and sports nutrition (BCAAs, diet supplements).

To ensure that the strong but short functional boost of tyrosine does not fizzle out, you should adjust the amount of all basic substrates to your individual training or diet goals and, above all, supply proteins as consistently as possible throughout the day.

Functionality and mode of action of tyrosine

In contrast to amino acids from normal food, protein concentrates or amino acid combinations,individual amino acids such as tyrosine generally have the advantage that they can develop their very special functionality in isolation. This can happen better if the individual amino acid is dominant, i.e. enters the blood pool as isolated as possible. With complete protein sources, on the other hand, a large number of amino acids always enter the blood pool at the same time, whereby individual amino acids can compete for dominance to a certain extent. In this respect, individual amino acids should preferably be taken on an empty stomach.

Diets are often accompanied by unpleasant symptoms such as tiredness, fatigue and excessive desire to eat, which can lead to the diet being discontinued or at least severely hinder it. These symptoms are often due to an insufficient intake of certain nutrients. A deficiency of the proteinogenic amino acid L-tyrosine can also become a limiting factor, as this amino acid fulfills important functions.

Tyrosine is the starting substrate for the formation of thyroid hormones (T3) and (T4) as well as all catecholamines. The latter category includes the hormones and neurotransmitters in the central nervous system L-DOPA, dopamine, adrenaline and noradrenaline. During the biosynthesis of catecholamines from tyrosine, the enzyme tyrosine hydroxylase first produces L-DOPA, which in turn produces dopamine, colloquially known as the "happiness hormone", with the help of aromatic L-amino acid decarboxylase (AADC). Dopamine can be hydroxylated by dopamine beta-hydroxylase to noradrenaline, which - optionally catalyzed - can be converted to phenylethanolamine N-methyltransferase - adrenaline.

Catecholamines and thyroid hormones are very important for the normal performance of the organism, which is why the availability of their starting substrate - L-tyrosine - is also important.

In addition to high-dose L-tyrosine (500 mg per capsule), Peak Tyrosine also contains a vitamin B complex with niacin, vitamin B6 and vitamin B12. This complex contributes to the reduction of tiredness and fatigue and to the maintenance of a normal nervous system and energy metabolism. Vitamin B6 is also an important factor when it comes to regulating the hormonal system and - together with vitamin B12 - the normal functioning of the immune system, which rounds off the product's functional spectrum.
