Vitamin D, Iron, B12 – What Does My Body Really Need?
Identifying and addressing deficiencies – is supplementation useful?
Many people often feel tired, lacking energy, or unfocused—without realizing that a deficiency in key micronutrients may be the cause. The most common culprits: Vitamin D, Iron, and Vitamin B12. These nutrients are essential for energy production, immune function, blood formation, and many other bodily processes.
☀️ Vitamin D – The Sunshine Vitamin
Vitamin D is mainly produced in the skin through sunlight exposure. However, during autumn and winter months, sunlight is often insufficient. A deficiency can lead to fatigue, increased susceptibility to infections, or muscle weakness.
Tip: Have your blood levels of vitamin D checked. If a deficiency is found, targeted supplementation—ideally combined with vitamin K2—can be helpful.
🩸 Iron – Vital for Oxygen Transport & Energy
Iron deficiency is especially common in women of childbearing age. Symptoms may include pale skin, brittle nails, hair loss, and fatigue. Athletes and vegetarians are also more frequently affected.
Tip: A blood test including ferritin levels can reveal your iron stores. In case of deficiency, iron-rich foods (e.g. meat, legumes, oats) or specific supplements may help—always under medical supervision.
🧠 Vitamin B12 – Nerve Protection and Vitality
Vitamin B12 is found primarily in animal-based products. Vegetarians, vegans, and older adults with reduced absorption in the gut often develop a deficiency without noticing—resulting in symptoms like tingling, concentration problems, or anemia.
Tip: A simple blood test for B12 levels provides clarity. If levels are low, tablets, drops, or injections can restore balance.
💊 Conclusion: Supplements – Yes or No?
Not everyone needs supplements. However, if you have risk factors or symptoms, it’s wise to check your blood levels. Targeted supplementation can be beneficial if a deficiency is confirmed. Taking supplements without lab confirmation is not recommended.
Our advice:
Talk to your doctor about your symptoms and have your blood tested regularly. This ensures your body receives everything it needs—without the risk of overdosing.
