Frequently asked questions
Do I need supplements if I eat well?
A balanced diet covers most needs, but common gaps (vitamin D, B12, iron in some groups) may need supplements — ideally guided by a test.
Can I take too many vitamins?
Yes — especially fat-soluble vitamins (A, D, E, K) and iron, which can build up and cause harm. Stick to recommended amounts.
