Iron

Red blood cells · energy · oxygen transport. People take it for:

  • Hemoglobin and red blood cell production
  • Oxygen transport throughout body
  • Energy and fatigue reduction
  • Immune function
  • Cognitive performance

Why it works

Iron is essential for hemoglobin synthesis and oxygen transport. Deficiency is the most common nutrient deficiency worldwide, especially in women of reproductive age. Only supplement if deficient — excess iron is harmful.

How to take Iron

Best time to take

With Vitamin C on an empty stomach for absorption; or with food to reduce GI upset

Suggested dose

18mg daily for women, 8mg for men; therapeutic doses per blood test results only

Side effects and risks

  • Constipation is common — take with Vitamin C and probiotic
  • Nausea if taken on empty stomach
  • Excess iron causes oxidative damage — test before supplementing
  • Dark stools (normal)

Iron interactions

  • Works withVitamin C

    Vitamin C markedly increases absorption of non-heme iron, the form in supplements and plants. Taking them together is one of the simplest ways to get more from the same dose.

  • CautionPsyllium Husk

    Soluble fibre such as psyllium can bind iron in the gut before it is absorbed. Keep at least two hours between them.

  • CautionCalcium

    Iron absorption drops sharply when calcium is taken at the same time. Take iron on its own, at least two hours from calcium or a dairy-heavy meal.

  • CautionZinc

    Iron and zinc compete for the same transporter when taken together without food. Split them across the day rather than dropping both at breakfast.

  • NoteMagnesium Glycinate

    Iron and magnesium compete for uptake when swallowed together. Not a serious conflict, but two hours apart keeps both working.
