Ferritin is a protein inside cells that stores iron so your body can use it later. It is sometimes used to determine the origin of certain anemic syndromes. You can increase your level of ferritin by consuming folate as a dietary complement or in foods like liver, avocado, orange juice, spinach, etc. Still you should wait till you see your doctor, so they can run more tests and be certain of why it is that you have a low ferritin level.
Selenium is an important co-factor for the enzyme form of glutathione. Selenium is necessary for formation of glutathione containing enzymes. For that reason, consuming foods rich in selenium will promote the production of glutathione. These foods include cereals, oats, Brazil nuts, walnuts, legumes, tuna, beef, poultry, cheese, eggs. Alpha lipoic acid, or ALA, promotes the synthesis of glutathione within the body, thereby increasing glutathione levels. Foods rich in alpha lipoic acid include: spinach, tomatoes, peas, Brussels sprouts, rice bran and mayonnaise. Many of these foods are naturally high in glutathione. Eating these foods increases the bioavailability of this important antioxidant.
