Vitamin B is an essential nutrient that helps produce and maintain healthy nerves and blood cells. It also plays a significant role in carrying oxygen from the red blood cells. So, any deficiency in Vitamin B12 can lead to various kinds of issues in your bodily functions. A normal, healthy person requires a daily Vitamin B12 dosage of at least 2.4 mcg. It's important to get your levels checked regularly because a number of nagging ailments might be connected to a lack of B12, like the following issues.
1. You feel numbness:
Your nerves start shrinking and you will begin to feel numbness. This nutrient helps create myelin, which is the protective covering for your nerves. Thus if you feel sudden numbness once in a while it could be a sign of Vitamin B12 deficiency.
Extreme tiredness or weakness and shortness of breath are all signs that you need to watch out for. Also, red blood cells won't be able to supply enough oxygen due to Vitamin B12 deficiency, which makes you feel weak.
