Feeling low energy can have many causes. Three nutrients regularly discussed with clinicians are vitamin B12, vitamin D, and iron. Here’s a practical overview to help you have a better conversation with your provider.
Why these three?
- Vitamin B12: Supports red blood cell formation and normal neurological function.
- Vitamin D: Involved in immune health and overall wellbeing.
- Iron: Essential for oxygen transport; low iron stores can contribute to fatigue.
How to choose a product
- B12 forms: Methylcobalamin or cyanocobalamin lozenges, sprays, or capsules.
- Vitamin D: D3 (cholecalciferol) is common; dosage depends on your blood levels and clinician guidance.
- Iron: Forms like ferrous bisglycinate may be gentler for some; always confirm need with testing.
Helpful habits
- Pair with a balanced diet and regular sleep/wake times.
- Re-test levels with your clinician as recommended.
FAQs
Q: Can I take all three together? A: Many do, but check timing and tolerance; your clinician can personalize a plan.
Q: How long does it take? A: Some people re-evaluate after 4–12 weeks.
