How much Iron Ferrous Sulfate?

[CathyJoH]

My transferrin saturations is just at 20%. It was recommended I take Iron Ferrous Sulfate but confused at how much and how often. Would appreciate advice on this. Thank you!

If I remember correctly your ferritin was 45 but later 108?

If you take blood thinners, iron binds with blood thinners, potentially reducing the effectiveness of the blood thinners and of the iron so check with your doctor. Otherwise take 325 mg of ferrous sulfate or 50 mg to 75 mg of iron bisglycinate with 100 mg of vitamin C or some orange juice since that helps its absorption. Also take Lactobacillus plantarum 299v as it also helps its absorption. Ferrous sulfate is fine for most people, but if you have problems with constipation, iron bisglycinate is better.

Take it every other day preferably at night at least 1 hour before a meal or coffee or tea and at least 2 hours after a meal or coffee or tea since iron is absorbed better on an empty stomach and the tannins in coffee and tea limit absorption. If you take magnesium, calcium or zinc even in a multivitamin, take them at least 2 hours apart since they interfere with the absorption of iron. Also antacids interfere with its absorption so should be taken at least 4 hours before the iron or at least 2 hours after. Don't take your iron tablets before or after exercise since inflammation peaks after a workout. Don't take tumeric as it can interfere with the absorption of iron. If you take thyroid medicine don't take it within 4 hours. It takes several months for the iron tablets or iron infusion to slowly raise your ferritin. Ask for a new blood test after 3 months. Stop taking any iron supplements including in a multivitamin 48 hours before the test, avoid a heavy meat meal the night before and fast after midnight and have your test in the morning before 9 am if possible.
