When you start taking vitamin B12, your body will begin to absorb it. The problem with this is that you have to take large doses in order to see any effects. That’s not good for your body and it may lead to diarrhea and all-over itchiness. To help prevent these effects, it’s a good idea to follow the manufacturer’s instructions. However, if you don’t know how much vitamin B12 you need, you may experience diarrhea.
The symptoms of a vitamin B12 deficiency include fatigue, reduced sensitivity to pain, blurred vision, a sore tongue, and a poor memory. In rare cases, a person may not show any symptoms for years. But if you don’t take any supplements, your body will be unable to absorb the vitamin, so it’s important to get a diagnosis as soon as possible.
A person with low levels of vitamin B12 may be pale or yellow, which is a sign that they need more of it. People with low B12 levels may also experience sluggishness and tiredness. Ultimately, they might experience a plethora of symptoms. If you’re not sure whether you need a supplement, talk to your doctor. You’ll be surprised by what you might discover.
