L-Tyrosine: special amino acid This amino acid is a basic building block for the synthesis of the thyroid hormones thyroxine and triiodothyrionine and is therefore extremely important for the energy metabolism. L-Tyrosine is also required by the body to produce neurotransmitters such as dopamine, adrenaline and noradrenaline and the pigment melanin, which is responsible for coloring the skin and hair. In food The highest amounts of the amino acid are found in animal foods. They include pork, beef and fish such as sardines, mackerel and herring.Vegetarians and vegans, however, can rest easy as there are many good plant-based sources of L- Tyrosine: Soybeans, peas, peanuts, almonds and oatmeal contain high amounts of the amino acid. Buy tyrosine at Fairvital highly dosed with 500mg per capsule vegetarian and vegan gluten-free, lactose-free, fructose-free without silicon dioxide Combi tip: The amino acid L-tyrosine is together with the trace element Iodine essential for the production of thyroid hormones (T3, T4).

Selenium: for the thyroid The trace element selenium is far more important for our cells and our health than is often assumed. It is an essential component of various enzyme systems that neutralize free radicals. Selenium thus contributes to cell protection. Selenium is also important for the immune system and contributes to strong nails and strong hair. Since selenium can contribute to normal sperm formation the trace element can be important for male fertility. The thyroid gland is also dependent on an adequate supply of selenium for its function. Selenium from selenium yeast In this process, yeast is grown on selenium-rich culture media and then dried. This allows the yeast to naturally synthesize a high proportion of organic selenium. The resulting yeast has a high concentration of the selenium-containing proteins selenomethionine and selenocysteine, these compounds are also naturally found in plants. Organic selenium compounds can be absorbed by the body better than inorganic ones. Selenite and selenate compounds must first be converted into biologically active selenoproteins such as selenomethionine or selenocysteine ​​in the organism. The American Academy of Sciences considers 200 micrograms a day to be safe and appropriate as a dietary supplement. Selenium tablets from Fairvital highly dosed 200µg selenium per tablet organic compound good bioavailability supports the thyroid gland for a good immune system important for cell protection vegetarian and vegan gluten-free, lactose-free, fructose-free without magnesium stearate and silicon dioxide

Vitamin B12 with folic acid This dietary supplement from Fairvital combines vitamin B12 (methylcobalamin) with folic acid (vitamin B9). Both forms are very bioavailable and can be optimally utilized by the body. One tablet daily provides you with 500 µg vitamin B12 and 100 µg folic acid. Vitamin B12 Vitamin B12 (scientifically: cobalamin) is one of the 8 water-soluble B vitamins and occupies a special position. On the one hand, it is the only B vitamin that can be stored by the body in significant amounts (2000-4000 µg). This mainly takes place in the liver. On the other hand, the absorption of vitamin B12 depends on a special transport molecule, the so-called intrinsic factor (IF). The formation of this transport molecule takes place in the parietal cells of the stomach. Intake of vitamin B12 The intrinsic factor binds to the B12 in the small intestine and transports it to special receptors in the intestinal mucosa. If the formation of the intrinsic factor is disturbed by gastric diseases, a vitamin B12 deficiency can occur. However, vitamin B12 can also be absorbed by passive diffusion . This is usually achieved with high doses of vitamin B12 (from 500-1000 µg). Vitamin B12 for the nerves The vitamin plays an important role in a well-functioning nervous system and supports mental well-being. In addition, it is involved in cell division and the formation of red blood cells. The energy metabolism is also dependent on a sufficient B12 level, so that the macronutrients from the food can be optimally utilized. B12 in food Since vitamin B12 is primarily found in animal foods (e.g. eggs, dairy products), supplementation is particularly useful for vegetarians and vegans. Plant sources include fermented vegetables and legumes in particular, but the amount contained is not sufficient to meet daily needs. Algae such as Chlorella and spirulina are touted as good sources of B12, but again, amounts are usually very small and some of the B12 form it contains is not biologically active. Folic acid Folic acid, like vitamin B12, is also one of the water-soluble B vitamins and is also known as vitamin B9. Only very small amounts are stored in the liver, which are sufficient for about 3 to 4 months. Folic acid is only stored in the inactive form, which the body cannot use. However, a sufficiently high vitamin B12 level can activate folic acid and make it accessible to the body. Function of folic acid Together with cobalamin (B12), folic acid is necessary for a normal homocysteine ​​level in the blood by supporting the breakdown of homocysteine ​​into methionine. Like vitamin B12, folic acid contributes to a < strong>normal blood formation or formation of red blood cells and to a normal function of the immune system. Folic acid also supports the mental function and is important for women before and during pregnancy as it contributes to the formation of maternal tissue. Folic acid in food Unlike B12, folic acid is primarily found in plant foods. Good sources include spinach, lamb's lettuce, asparagus, peas, chickpeas, soybeans, kale, and Brussels sprouts. Animal sources include pork liver, cocoa, eggs, and brie. Vitamin B12 with folic acid from Fairvital 500µg B12 and 100µg folic acid per tablet Plays a role in blood formation and cell division supports the immune system promotes normal homocysteine ​​levels for more energy with B12 as methylcobalamin small tablets, easy to swallow vegetarian and vegan gluten-free, lactose-free, fructose-free without magnesium stearate and silicon dioxide
