Thirty-five percent of Americans supplement their diet with multivitamins, according to the American Dietetic Association. While vitamin and mineral supplementation may seem like a safe way to make sure you get all the nutrients you need to be healthy, some vitamins and minerals interact with medications, making them more or less effective. Iron supplements interact with eight different types of medications. However, iron supplements do not interact with the medication Adderall.


Adderall is a central-nervous stimulant that affects chemicals in your brain and nerves to help control impulsive and hyperactive behavior. It is used to treat narcolepsy and attention deficit hyperactivity disorder, or ADHD. Adderall is a serious medication that can be addictive, and should only be taken under the direction and guidance of your physician. In children, Adderall can affect growth rate, making it important that you closely monitor the growth and weight status of your child while he is taking the medication.

Iron Supplements

Iron is an essential mineral, meaning your body cannot manufacture it and it must be obtained from your diet. Iron is needed for the production and function of a number of different proteins and enzymes. It also plays a very important role in the transportation of oxygen in your body. Iron-deficiency anemia is one of the most common nutritional disorders in the world, according to the Office of Dietary Supplements. If you are iron deficient and unable to adequately meet your daily iron needs through your diet, you may need iron supplements. Your doctor determines your daily iron dosage. Most adults who are iron deficient and not pregnant usually need about 300 milligrams of ferrous sulfate a day.

Iron and Adderall

It is important that you tell your doctor about all the medications and supplements you take because of potential interactions. While iron supplements interact with a number of different types of medications, it appears as though it is safe to take iron supplements when you are on Adderall. However, you should first consult your physician before adding iron supplements to your diet when taking the stimulant.

Medications and Iron Supplements

Iron supplements interact with medications by inhibiting their absorption. If you need to take iron supplements, you should take them two hours before or after you take any medications. Medications known to interact with iron supplements include cholestyramine, colestipol, tetracyclines, ACE inhibitors, quinolones and levodopa. In addition, some types of birth control increase blood levels of iron, which may decrease your need for additional supplementation.
