Vitamin B12

• a normal psychological function
• the reduction of tiredness and fatigue
• the normal functioning of the nervous system
• a normal energy-yielding metabolism
• the normal functioning of the immune system

Vitamin B12 is important for the production of red blood cells, among other things. Red blood cells are needed to transport oxygen in your blood. Vitamin B12 is also important for the proper functioning of the nervous system.

A vitamin B12 deficiency is usually caused by impaired absorption of the vitamin in the digestive tract. Vegans, who abstain from animal products for extended periods, are also at risk of vitamin B12 deficiency. It often takes years for symptoms of such a deficiency to become apparent, as the body can store vitamin B12.

A vitamin B12 deficiency can also lead to a vitamin B11 (folic acid) deficiency. Folic acid plays an important role in the functioning of the nervous and immune systems.

A vitamin B12 deficiency can also cause pernicious anemia, a form of anemia. Symptoms include fatigue, shortness of breath, angina (chest pain), and decreased appetite. Furthermore, vitamin B12 appears to play a role in memory and thinking skills. Older adults with a vitamin B12 deficiency may experience memory problems.

A vitamin B1 deficiency can therefore cause various complaints:

• A form of anemia. Anemia can cause symptoms such as fatigue, dizziness, palpitations, and tinnitus.
• Tingling in the fingers (paresthesia)
• Memory loss
• Coordination disorders
• Muscle weakness in the legs

These symptoms may be attributed to other deficiencies or problems, so always consult a doctor if you experience them persistently or are concerned.

B12 is a water-soluble vitamin. This means it's present in the fluids of food. It's absorbed directly into your bloodstream, and if your body doesn't need it at that moment, it's excreted almost immediately in your urine. Therefore, it's important to get your B12 regularly. Vitamin B12 is mainly found in animal products such as milk and dairy products, meat and meat products, fish, and eggs.

Vitamin B12 is found almost exclusively in animal products. To ensure sufficient vitamin B12 intake, vegans are generally advised to take a vitamin B12 supplement or use products with added vitamin B12.

There is no established upper limit for vitamin B12. In these cases, a maximum of 5 times the recommended daily amount is usually assumed, i.e., between 14 and 19 mcg per day.

One capsule of Guud Flow contains 8 mcg vitamin B12.

Whether and for how long you can take vitamin B12 depends on your individual needs and personal situation. Ensure you get enough vitamin B12 through your diet and supplement your diet with a supplement if necessary. Consult a doctor if you suspect a vitamin B12 deficiency and want personalized advice.

Folic acid supplementation can mask symptoms of anemia caused by vitamin B12 deficiency. Symptoms disappear, or appear to be due to a folic acid deficiency, while the underlying B12 deficiency remains untreated.

Taking vitamin B12 at the same time as folic acid prevents this masking effect. Furthermore, vitamin B12 and folic acid work together in the body. Taking both vitamins together can ensure that these processes run optimally, which can be beneficial for overall health.
