How to increase hemoglobin: Home remedies Last updated Tue 6 November 2018 By Bethany Cadman Reviewed by Daniel Murrell, MD Increasing hemoglobin Normal ranges Symptoms of low hemoglobin Causes of low hemoglobin Takeaway Hemoglobin is a protein found in the red blood cells. These cells are responsible for carrying oxygen around the body. In addition to transporting oxygen, hemoglobin carries carbon dioxide out of the cells and into the lungs. Carbon dioxide is then released as a person exhales. Having low hemoglobin can make it difficult for the body to perform these functions. In this article, learn how to increase hemoglobin levels naturally. We also look at methods of testing and what the results show. How to increase hemoglobin A person can raise their hemoglobin levels at home by: 1. Increasing iron intake Hemoglobin is an important component of red blood cells. A person with reduced levels of hemoglobin may benefit from eating more iron-rich foods. Iron works to boost the production of hemoglobin, which also helps to form more red blood cells. Iron-rich foods include: meat and fish soy products, including tofu and edamame eggs dried fruits, such as dates and figs broccoli green leafy vegetables, such as kale and spinach green beans nuts and seeds peanut butter 2. Increasing folate intake Folate is a type of vitamin B that plays an essential part in hemoglobin production. The body uses folate to produce heme, a component of hemoglobin that helps to carry oxygen. If a person does not get enough folate their red blood cells will not be able to mature, which could lead to folate-deficiency anemia and low hemoglobin levels. Good sources of folate include: beef spinach rice peanuts black-eyed peas kidney beans avocadoes lettuce Folate supplements are available for purchase online.
