Thorne Iron Bisglycinate provides 25 mg of iron per capsule in the bisglycinate form, where the iron is bound to the amino acid glycine. A bottle holds 60 capsules. Iron is an essential mineral your body uses to make haemoglobin, the protein in red blood cells that carries oxygen. Only take iron if a blood test shows you need it, and keep it well away from children.

What is in it
Iron bisglycinate is a chelated form of iron. It is generally gentler on the stomach than older forms such as ferrous sulfate, which is the main reason people choose it.
How 25 mg compares. Adult men need about 8 mg of iron a day and women aged 19 to 50 need about 18 mg. The adult upper level in the Australian and New Zealand Nutrient Reference Values is 45 mg a day, so one capsule a day is within it.
Who it suits
- Adults whose blood test shows low iron and whose doctor has suggested a supplement.
- Groups more likely to be low, such as women with heavy periods, vegetarians, vegans and regular blood donors, after a blood test.
- People who found other iron tablets hard on the stomach.
Who should check first
- No blood test yet: see your GP first. Tiredness has many causes, and taking iron you do not need can be harmful.
- Haemochromatosis or high iron levels: do not take iron.
- Children: keep the bottle out of reach. Iron overdose is dangerous for young children. Call the Poisons Information Centre on 13 11 26 if a child swallows any.
- Taking medication: iron can block the absorption of thyroid medicine, some antibiotics and osteoporosis medicine. Take them at least two hours apart and check with your pharmacist.
- Pregnant or breastfeeding: use the dose your doctor or midwife recommends.
How to use it
Follow the directions on the label and do not take more than it says. Iron absorbs best away from tea, coffee, dairy and calcium supplements. Taking it with a source of vitamin C can help. Dark stools are common with iron and are harmless. If you get constipation or stomach pain, speak to your pharmacist.
