Do you feel tired all the time even after a good night's sleep? Do you notice tingling in your hands or feet, forget things, or lack energy for work? Before you get used to living that way, it's worth checking something very simple: your vitamin B12 level. Deficiency of this vitamin is more common than people think—and it's easy to correct when caught early.
What is vitamin B12 and what is it for?
Vitamin B12 is an essential nutrient your body cannot produce on its own: it only comes from animal-based foods or supplements. It supports basic functions, and when it's missing, your whole body feels it:
- Red blood cells: without enough B12, anemia develops.
- Nervous system: it protects your nerves; that's why a deficiency causes tingling and numbness.
- Energy: it helps turn food into energy; constant fatigue is the most common symptom.
- Memory and focus: your brain needs it to work clearly.
Important: B12 is not a magic energy booster for people who already have normal levels. Its real benefit is correcting and preventing deficiency—which is why the first step is always measuring it with a blood test.
Symptoms of vitamin B12 deficiency
Deficiency develops slowly and its symptoms are often mistaken for stress or "age." Watch for:
- Tiredness and weakness that don't improve with rest
- Tingling or numbness in hands and feet
- Pale or slightly yellowish skin
- A swollen, smooth or burning tongue
- Memory problems and trouble concentrating
- Mood changes or irritability
- Dizziness or shortness of breath with exertion
Who is most at risk?
- People over 50: with age, the stomach absorbs B12 from food less effectively.
- Those taking acid reflux or heartburn medication (like omeprazole) long term.
- Those taking metformin for diabetes: this medication reduces B12 absorption.
- Vegetarians and vegans: B12 is only naturally present in animal-based foods.
- People with stomach or intestinal surgery, or digestive conditions like chronic gastritis.
Which foods provide vitamin B12?
Food should always be the first source:
- Beef liver: very high content
- Fish such as salmon, tuna and sardines: high
- Beef and chicken: moderate to high
- Eggs, milk, cheese and yogurt: moderate
- Fortified cereals: varies (check the label)
The problem is that eating well isn't always enough: if your stomach doesn't absorb the vitamin—because of age, medication or surgery—you can be deficient even with a good diet.
B12 injection vs. pills
Pills work well for mild deficiencies and as maintenance, as long as your intestine absorbs normally. The injection goes into the muscle and passes directly into the blood, without depending on digestive absorption. It's recommended when the deficiency is moderate or severe, there are neurological symptoms, or absorption problems exist.
At Clínica Hispana Nueva Salud we administer vitamin B12 injections and also offer vitamin IV therapy that combines vitamins with full hydration, depending on what your body needs. And if the underlying cause is something else—thyroid, iron-deficiency anemia or a chronic condition—the same blood test helps us detect it.
How often is the injection given?
It depends on your starting level and the cause. A common plan is a correction phase with weekly injections, followed by maintenance with one monthly injection. At your visit we define the right plan based on your results—we never dose "blindly."
