Yeah pretty much. You can get some side effects from iron tablets such as constipation, so try to eat iron-rich foods if you can - meat (esp red meat), seafood, green leafy veg, beans, dried fruit (raisins, apricots), iron-fortified cereals such as weetabix, cheerios, readybrek (google it for more ideas on that one, they're just the ones that popped into my head) and also things like brown bread and pasta. Also dark chocolate too apparently.
You need to make sure you're getting plenty of vitamin c too because that helps you to absorb iron. So if you do take tables, make sure you take them with a glass of orange juice. Think about getting vitamin c into your diet too if you're trying to help boost your iron levels through diet.
Not saying you shouldn't take the tablets, just that if you get any unfavourable side effects that there are other ways you can deal with it! My levels weren't too bad (but they were borderline) and changing my diet really did work. Xx
