Are you sleeping well, but still feeling exhausted? Do you sometimes feel dizzy, have a strange tongue, or have a less reliable memory? What if all these little signs—often attributed to stress or age—were hiding something else? One avenue to explore: your vitamin B12 levels.
Persistent fatigue: when the body sounds the alarm
It’s not a temporary fatigue that disappears with a coffee or a lie-in. No, it follows you everywhere, like a veil in your head . Vitamin B12 plays a key role in energy production. When it is lacking, the body struggles to produce enough red blood cells, and the entire organism functions in slow motion .
Dizziness, unsteadiness… and a feeling of floating
You get up a little too quickly and suddenly the room spins? You’re going up a flight of stairs and your balance falters? These temporary dizziness episodes could be linked to a B12 deficiency. It’s not necessarily serious, but it’s a warning sign that shouldn’t be ignored.
Soft muscles, for no apparent reason
Do you have trouble carrying your shopping bags or opening a jar? It’s not necessarily a fitness issue: a B12 deficiency can cause muscle weakness because your muscles aren’t getting enough oxygen.
Tingling in the fingers or feet? It’s not always harmless
These tingling or numb sensations may be related to mild nerve damage . And guess who’s essential for the proper functioning of the nervous system? B12, of course! A prolonged deficiency can slow down the transmission of nerve signals , which manifests itself in tangible ways.
Failing memory and foggy mind
Memory lapses, difficulty concentrating or making simple decisions… This mental fog isn’t always related to stress. Vitamin B12 helps keep the brain oxygenated. A lack of it can make you feel less clear- headed .
A smooth tongue and a pale complexion
Another somewhat surprising sign: an abnormally smooth, red, and sensitive tongue. And in terms of complexion, you may notice a certain pallor, a sign that your body is not producing enough red blood cells. Once again, B12 may be the culprit.
But then, what is this famous vitamin B12 used for?
It doesn’t just feel good : it’s essential for our overall balance. During pregnancy, for example, it contributes to the proper development of the fetus. It also supports bone health, helps prevent certain low moods by promoting the production of serotonin, and supports the immune system . In short, an important vitamin for our bodies.
