Vitamin B Complete - What is it?This blood test measures four different B vitamins in the blood and vitamin D. This gives you a complete overview of your vitamin B and D status. In With this blood test we measure your vitamin B1, vitamin B6, vitamin B12, vitamin B11 (folic acid) and vitamin D.
This test is ideal for vitamin B complex vitamin supplements or vitamin pills to to measure the effect. It sometimes happens that you unknowingly get too high a vitamin B value, especially B12.
With this blood test you can see whether you are taking the vitamin supplements properly and whether they work well for you or whether there is a problem with absorption. There is scientific evidence for the use of vitamin B supplements that they can increase the values to such an extent that there is vitamin B intoxication.
What do we determine?
Vitamin B1Vitamin B1 or thiamine is important for the heart, brain and nervous system and it is also an aid to convert carbohydrates into energy. It can be found in wheat products such as bread, but also in dairy products (milk and cheese) and potatoes. A deficiency can cause psychological problems such as depression, memory loss or concentration problems. You may also experience numbness in your legs or heart problems. We often see a thiamine deficiency in alcoholics. Thiamine intoxication (too much vitamin B1) does not actually occur, because your kidneys urinate the surplus.
Vitamin B6Vitamin B6 (pyridoxine) is important for the balance in amino acid metabolism. You can make proteins from this again. Vitamin B6 also plays a role in the immune system, hormones, blood production and the nervous system. Too much vitamin B6 can cause so-called intoxication. This can cause tingling in the arms and legs. This is called peripheral neuropathy. A deficiency leads to anemia. Intoxication with vitamin B6 is more common than a deficiency due to the use of vitamin supplements.
Vitamin B12Vitamin B12 (cobalamin) is necessary for the production of red blood cells and proper functioning of the nervous system. It is almost exclusively found in animal products, so vegans are advised to test themselves if they have symptoms. With a deficiency you will experience tingling, fatigue, dizziness, memory loss and muscle weakness. Only test vitamin B12? View the vitamin B12 blood test
Vitamin B11Vitamin B11 (folic acid) is necessary for the production of red and white blood cells and proper functioning of the nervous system. In addition, it is so important for pregnant women that it is recommended to take folic acid 4 weeks before pregnancy until the first trimester. A deficiency causes anemia, intestinal complaints and fatigue. Vitamin B11 is also called folic acid, but also folate or vitamin B9. Too much folic acid from tablets (PMG) can be harmful because it masks a vitamin B12 deficiency.
