I am deficient in iron what foods should I eat? Does vitamin B12 help too?
Dark, leafy greens such as kale.
I made a big batch of colcannon yesterday. 
What is kale? Anyway I heard greens like spinach are lower in iron than people think and it isnt absobed easily.
Kale.
Got any kale recipes?

Suggestions in the quote above. I use it in colcannon, which is mashed potatoes with kale. Make the mashed potatoes as usual. Cut the stems from the kale and discard (mine go onto the compost pile), chop the leaves coarsely and boil in salted water, drain, and add to the potatoes. A few weeks ago my roommate cooked chopped kale in a skillet with onions and made an omelette with them.
Other good sources of iron include red meat, fish and poultry.
Liver and onions, yum.
I’ve heard that B12 supplements are a waste of money as B12 cannot be absorbed by the human body that way, B12 is present in meat and dairy, other than that B12 can only be given by injection. Maybe one of our medical types can clarify.
Vitamins only ensure you will have the world’s most expensive pee.
Red meat is a good source of iron, as is blood sausage.
B12 is worthless unless you suffer from B12 deficiency, which you probably don’t.
New iron deficiencies are usually worked up to find the cause. The most worrisome is hidden intestinal bleeding from ulcers or tumors. If you are anything but severely iron deficient, you may be advised to take supplemental iron unil you return to normal, and then a better diet should suffice. For a severe deficiency you might need prescription-level iron supplements. Iron deficiency is usually the result of excess blood loss, particularly through menstruation if the individual is otherwise healthy. It can also result from very poor dietary intake, but the body does not tend to lose iron except by bleeding so this is not usually a cause. There are good reasons to eat lots of other additionally nutritious foods but no reason not to zero in on what you are deficient in, and replace it with a pill.
Proper medical advice from a physician is essential.
B12 will not help iron deficiency. The majority of people who are deficient in B12 become deficient because they don’t absorb it properly in the first place (especially the elderly) so B12 deficiency is most commonly corrected by giving injections of it.
Fresh spinich in place of lettuce on sandwiches has always worked for me. From the Red Cross information sheets, the idea being that increased vitamin C will improve iron absorption.
I found that Luna bars, with 30% daily iron in each, helped keep my iron in the healthy range when I was very busy and not eating particularly well. As a nutrition bar designed for women, the iron is in there to counter monthly iron loss.
Beef?
Instant Cream of Wheat. (The instant type is fortified with extra iron.) Molasses on it will boost the iron even further. Macaroni. Meat.
Tris
Liver?
Oysters!
No cites for any of what follows, sorry"
Guavas (Guayabas). I also understand that there is something in them that makes the iron easier to absorb and use for the body. Iron from animal sources is easier to assimilate for the body than iron from vegetable sources. Guavas have something in them that makes their iron as usable as that of animal sources.
They are also good sources of Vitamin C and Calcium
Yummy, too and easy to find in preserve form.
When I was having iron level issues (due to heavy periods and generally not eating properly), my GP said that there’s some evidence that vitamin C helps with iron absorption, but this is not as well proven as the vitamin D/calcium combination. Still, it can’t hurt to make sure you’re getting enough C in your diet. Fresh fruits and veggies never killed anybody.
The iron in meat is the most bioavailable, then that in plant foods, and least of all the elemental iron used in iron-enriched flours and cereals. However, any of the iron will help - you just need somewhat more of the less absorbable types.
Be cautious with iron suppliments. They can cause upset tummies and killer constipation (in my experience this is less of a problem with the ones made from animal sources than the cheaper ones that use non-biological sources), and are toxic if you overdo. Take them with meals if you take them at all, and stick to the recommended dose.
