Iron Deficiency Symptoms and the Best Iron Supplement for Women UK

Iron deficiency is the most common nutritional deficiency in the UK, affecting up to 1 in 5 women of childbearing age.

Common symptoms of iron deficiency

  • Persistent fatigue — feeling tired even after adequate sleep
  • Pale skin — reduced haemoglobin affects skin colour
  • Shortness of breath — less oxygen carried to muscles
  • Cold hands and feet — poor circulation from reduced red blood cell production
  • Brain fog and difficulty concentrating
  • Brittle nails and hair loss
  • Restless legs — particularly at night

Who is most at risk in the UK?

Women are significantly more at risk than men due to monthly blood loss. Other high-risk groups: vegans and vegetarians, pregnant women, athletes (especially endurance runners), and people with digestive conditions.

Why standard iron supplements cause stomach problems

Most iron supplements use ferrous sulphate — poorly absorbed and commonly causing constipation, nausea and stomach cramping. This leads many people to stop taking their supplement before it has any effect.

Plant-based iron: a gentler alternative

Iron from plant sources is increasingly recognised as gentler on the digestive system while maintaining good bioavailability. Combined with Vitamin C (which significantly increases iron absorption), plant-based formulations offer a practical solution for people who cannot tolerate standard iron supplements.

BestFerrin — plant-based iron support formula

BestFerrin is formulated with plant-derived iron alongside co-factors for absorption, designed for people who struggle with conventional iron supplements.

How to increase iron absorption

  • Take iron with Vitamin C (orange juice, kiwi, peppers)
  • Avoid tea, coffee and calcium-rich foods within 1 hour of your supplement
  • Cook in cast iron pans — small amounts of dietary iron transfer to food
