L-Tyrosine is an amino acid that your body partially produces itself from phenylalanine, and that also occurs naturally in high-protein products such as cheese, nuts, soy, and eggs. This L-tyrosine powder from Vit4ever provides the amino acid in powder form, measurable with the included scoop. One bag contains 500 grams, more than enough for months of use.
While many supplements nowadays are complex mixtures of ten or more ingredients, this powder has been deliberately kept simple, without minerals or herbal extracts. You can find the full list of ingredients further down on this page. With the included scoop, you measure out 1 serving of approximately 1.5 g every day, which makes use straightforward.
The L-tyrosine in this powder is not synthetically created in a chemical reactor, but obtained through plant-based fermentation. Microorganisms convert plant sugars into the desired amino acid, a process comparable to the fermentation used in sourdough bread, but focused on one specific substance. The result is a powder without solvents or chemical residues. After fermentation, the amino acid is separated from the rest of the fermentation mixture, purified, and dried into the fine, crystalline powder in the bag. Thanks to its fine particle structure, L-tyrosine powder dissolves easily in water, juice, or a protein shake, without you having to stir until your arm gets tired. The starting material for the fermentation is a plant-based sugar source, which microorganisms convert step by step into the desired amino acid.
Vit4ever does not add fillers, colorings, or preservatives to this powder. The powder is suitable for a vegan diet and is free from gluten, lactose, gelatin, and GMOs. What many people do not know is that pure amino acid powders are relatively prone to contamination during production, because there are no binding agents to dilute impurities. A trace of contamination is more quickly detected in an analysis of a pure powder than in a product with ten other ingredients mixed in. That is why Vit4ever has every batch independently tested for purity in a certified laboratory, so you know that what is in the bag is what is stated on the label. This testing is carried out separately from the company's own production line, in an external laboratory, which reduces the chance of errors in quality control.
You add a level scoop of tyrosine powder to water, juice, or a shake and stir until it has dissolved. Some people take this L-tyrosine powder on its own between meals, while others combine it with breakfast or a shake; it is mainly a matter of personal routine. The most important thing is to let the powder dissolve completely before drinking it; if a layer remains at the bottom, you will not receive the full dosage. Because it is a concentrated powder, you only need a small amount each time, which means a 500-gram bag lasts a long time. With daily use of one scoop, a 500-gram bag lasts over ten months, making it one of the most affordable ways to add this amino acid to your diet. The scoop is included in the packaging as standard, so you do not have to weigh or estimate. Stick to the recommended daily amount on the label.
In short: this is L-tyrosine powder, obtained through fermentation rather than synthesis, with a scoop for easy dosing. A simple, affordable bulk package.
Only l-tyrosine, with no added fillers, colorings or preservatives.
Not synthetically produced, but through plant-based fermentation, without solvents or chemical residues.
The included measuring scoop ensures you measure the same amount every time, allowing you to control the quantity yourself.
A concentrated powder where you only need a small amount per use, so one bag lasts a long time.

L-tyrosine is an amino acid and a building block of proteins, naturally found in foods such as nuts, soy, cheese, and eggs.
Through plant-based fermentation. Microorganisms convert sugars into tyrosine, meaning it is not synthetic and free from solvents.
Dissolve one level scoop (approx. 1.5 g) in water, juice or a shake and stir until dissolved.
Yes, and with even more attention to this: with pure amino acid powders without binding agents, the chance of contamination during production is higher, which is why Vit4ever has every batch tested separately for purity.
With powder, you measure out the recommended serving yourself using the scoop, and you can easily mix it into a drink.
A 500-gram bag provides approximately 333 servings of 1.5g, which, with one scoop per day, is ample for months of use.
