Why Energy Levels Can Drop When Vitamin B12 Is Low
If you’ve been feeling unusually tired even after getting plenty of rest, your body might be trying to tell you something — especially about Vitamin B12. This vital nutrient helps your red blood cells deliver oxygen throughout the body, keeping your energy steady and your mind alert. When B12 levels drop, that oxygen transport slows down, leading to feelings of exhaustion, weakness, or sluggishness that no amount of sleep seems to fix.
Beyond fatigue, early warning signs can appear in small but noticeable ways — tingling or “pins and needles” sensations in your hands or feet, paler or slightly yellow-toned skin, or a sense that your body just doesn’t feel as strong as usual. These are your nerves and blood cells sending quiet signals that something might be off balance.
