What I keep seeing across our Mayfield and Royal Tunbridge Wells clinics is people coming in absolutely exhausted, convinced they need every vitamin under the sun, when what they really need is proper iron testing.
Here's the thing that keeps coming up when I look at fatigue cases: everyone talks about B12 and vitamin D, but iron deficiency is incredibly common and often missed. Your GP might do basic iron studies, but ferritin testing gives you the full picture of your iron stores.
I've noticed people describing that bone-deep tiredness, struggling to get through afternoons, feeling breathless on stairs they used to bound up. Sound familiar? Iron deficiency doesn't always show up as anaemia straight away. Your ferritin levels can be running low long before your red blood cells are affected.
The frustrating part is waiting weeks for NHS results when you're feeling dreadful. We can get your ferritin and full iron panel results within 24 hours, giving you clear answers about whether iron is behind your fatigue.
