Pay extra attention to your iron intake if you follow a vegan diet, since you rely solely on non-heme iron. Be aware that your body does not absorb non-heme iron as well as it does heme.

Broccoli, asparagus and dark leafy greens such as spinach, collards and kale are the richest iron sources among vegetables, while lima beans and kidney beans are iron-rich legumes.
For instance you should take more vitamin B which can also increase hemoglobin (as a supplement or from cereals, fruits, vegetables and milk), vitamin C (sources include citrus fruits and juices) which helps with the absorption of iron, and beet which can stimulate hemoglobin production.therwise you can increase iron by simply increasing the iron in your diet. Foods that have high amounts of iron in them include eggs, green vegetables (such as broccoli or famously spinach), red meat, dried fruits, nuts, beans, liver, pork, fish and shell fish.
