Feosol Original Iron Supplement — 65mg, 120 Tablets (4 Month Supply)

The form of iron doctors most commonly recommend — 65mg ferrous sulfate per tablet, supports red blood cell production, energy, and immune health. Trusted for over 70 years.

Iron Deficiency and Your Cycle

Heavy periods are the leading cause of iron deficiency in women of reproductive age. Each month, blood loss during menstruation depletes iron stores — and if your flow is consistently heavy, your body may never fully replenish them between cycles. The result is fatigue that feels disproportionate, brain fog that won't lift, and shortness of breath doing things that shouldn't wind you. Low iron is often the overlooked explanation.

Why Feosol

Feosol has been a trusted name in iron supplementation for over 70 years. Their Original formula uses ferrous sulfate — the form of iron most commonly recommended by doctors and the most clinically studied for treating iron deficiency anaemia. At 65mg of elemental iron per tablet (361% of daily value), one tablet a day is enough to support red blood cell production and replenish depleted stores.

Important: Ferrous sulfate is highly effective but can cause constipation or nausea in some people, especially on an empty stomach. Take it with food and a full glass of water to reduce this. If you have a sensitive stomach, a gentler iron bisglycinate formula may suit you better — speak to your doctor.

Signs You Might Be Low in Iron

  • Persistent fatigue even after a full night's sleep
  • Brain fog or difficulty concentrating, especially mid-cycle
  • Feeling cold more than usual
  • Shortness of breath during light activity
  • Pale skin or pale inner eyelids
  • Heavy periods that last more than 7 days

What to Know Before You Buy

Iron supplementation works best when confirmed by a blood test. A simple ferritin (stored iron) test from your GP will tell you whether your levels are genuinely low before you start supplementing. If they are, Feosol provides the potency needed to bring them back up efficiently.
