Dont take any iron tablets before you so see your Dr as some Iron tablets dont basically work the GP might suggest a Iron Infusion they are Brilliant work and no sickness

Maltofer iron drink over the counter helps me. Eating leafy greens will also give you an iron boost

You could try iron in liquid form? It tastes disgusting, but you might find it better for you.

Request an iron infusion, works better and more efficiently anyway. Iron rich foods – really depends if your body can absorb it or not from foods

Maltofer is better and fibre supplements.

As some others have mentioned, there are multiple different types of supplements you can take, some that are more gentle on your tummy. I’d definitely ask pharmacist or GP for most gentle. Even if it’s not as strong, if you can take it more often that’s better.. and not within roughly an hour of caffeine or dairy to allow it to absorb.
Also taking vitamin c with it helps it to absorb.
and again as has been mentioned, diet is huge, leafy greens, red meats, etc.

One tip I’ve learned is to cook meat in an cast iron pan, it increases iron absorption by like 85% I think. Also have vitamin c with any iron you eat. So steak and a slice of orange or lemon on the side is great!

Try to include beans and leafy greens in your diet.

I have an iron fish as one of the commenters said. Great product and a way people often don’t know about to get extra iron in.

I’ve never been any good at absorbing iron from tablets so I get an iron infusion on once or twice a year

Our family eats very little meat and I am concerned that they may be low in iron. I use an ‘Iron Fish’ in my cooking. Once any initial low iron levels have been rectified, this may be something that you may like to look at. https://luckyironlife.com/

I’ve always had trouble with really low iron. I did used to have iron infusions but haven’t had to have them since taking the iron supplement brand Ferrograd C.
Also make sure you are taking it first thing in the morning on an empty stomach. Do not take with milk/ dairy as it won’t be absorbed as well

I bought beef liver capsules for Iron deficiency as they are particularly high in iron, as I couldn’t eat fried chicken or beef liver.

Please do not take medical advise from others. Seek the help of your local GP. They can put a plan in place for you in terms of vitamins and iron enriched foods. This is what my GP did to raise my iron levels, along with regular testing to check levels, to ensure I did not need to go down the path of a transfusion

I found some iron pills which are easy to digest. Haven’t had any problems at all. Can’t remember the brand. Blooms the chemist got them. It was a little container with a yellow lid I think.
