You have 2 options:
1. Iron supplements: it’s best to buy those that also have folic acid to help absorb the iron….. Or try molasses with iron
2. FOOD: beetroot, liver, spleen, heart, spinach, grapes, raisins, dates, kidney beans… if you Google you will find more.. Some people drink the water from boiling beetroot. You’d also have to eat a lot of oranges to facilitate absorbing the iron.
