Yes. The National Eye Institute (NEI) says the AREDS and AREDS2 formulas "do not substitute for multivitamins," and most trial participants took both. A multivitamin alone cannot replace AREDS2, because the trial doses were much higher. The main caution is adding up: the NIH Office of Dietary Supplements (ODS) notes that combining supplements makes intakes above upper limits more likely, and zinc is one to watch. Bring a list of everything you take to your eye doctor or pharmacist.
If you already take a daily multivitamin and your eye doctor suggests an AREDS2 formula, it is natural to ask whether the two can go together, or whether one makes the other unnecessary. The researchers who ran the AREDS trials addressed this directly.
This article covers what NEI says, why a multivitamin cannot stand in for AREDS2, and how to avoid getting more of some nutrients than you mean to.
What NEI says
NEI's AREDS/AREDS2 frequently asked questions page answers the question plainly. Asked whether you can take a daily multivitamin with one of the formulas, NEI replies: "Yes. The AREDS and AREDS2 formulas do not substitute for multivitamins."
NEI adds that combining them was common in the trials themselves. In AREDS, two-thirds of participants took multivitamins along with the study formula. In AREDS2, almost nine of ten did.
Why a multivitamin cannot replace AREDS2
NEI also answers the reverse question: can a multivitamin alone give the same benefit? "No. The vitamins and minerals tested in AREDS and AREDS2 trials were provided in much higher doses than what is found in multivitamins." Because so many participants were already taking a multivitamin, NEI concludes that "taking an AREDS formulation clearly provided a benefit over and above multivitamins."
NEI's patient page on AREDS 2 supplements says the same thing another way: "You can't get the right mix of these vitamins and minerals from food or from regular multivitamins."
That benefit applies to specific people. NEI says the formulas benefited people with intermediate AMD or late AMD in one eye, with no benefit for people with early AMD or without AMD. See What Is AREDS2 and Who Needs It? for more.
The real risk: doubling up
The AREDS2 formula already contains high amounts of some nutrients. NEI lists, per day, vitamin C 500 mg, vitamin E 400 IU, zinc 80 mg, copper 2 mg, lutein 10 mg and zeaxanthin 2 mg. A multivitamin may add more of some of these on top.
The ODS multivitamin/mineral fact sheet explains why this matters. Upper limits (ULs) "are the maximum daily intakes unlikely to cause adverse health effects," and when intakes go above the UL, "the potential risk of adverse effects increases." ODS reports that multivitamins can raise the chance of going over some ULs, and that "excess nutrient intakes are even more likely among MVM users who also take single vitamin and mineral supplements." In U.S. survey data, about 10 to 15% of multivitamin users had excessive intakes of vitamin A, iron and zinc.
ODS's consumer guide, Dietary Supplements: What You Need to Know, adds that side effects are most likely "if you take them at high doses, or instead of prescribed medicines, or if you take many different supplements." It also points out that fortified foods add nutrients too, so "you may get more of these ingredients than you think, and more might not be better."
Zinc: the nutrient to add up first
According to the ODS zinc fact sheet, the UL for adults is 40 mg a day, based on the levels of zinc that have an adverse effect on copper status. The AREDS2 formula's 80 mg is already twice that. ODS notes that zinc is found "in many multivitamin/mineral products," so a multivitamin can push the total higher.
ODS also explains that "the ULs do not apply to individuals who are receiving zinc for medical treatment, but such individuals should be under the care of a physician." If you take an AREDS2 formula, that is a good reason to keep your doctor informed about any other zinc you take. Two more points are worth knowing:
- ODS says taking 50 mg of zinc or more for weeks can interfere with copper absorption. NEI says copper was added to the AREDS formulas to reduce the risk of copper deficiency anemia, which is linked to high zinc intake.
- ODS says taking 25 mg or more of iron at the same time as zinc can lower zinc absorption. If your multivitamin lists iron, ask your pharmacist how to time them.
Our article on zinc and copper for eye health explains the 80 mg and 25 mg doses in more detail.
Keep in mind: the AREDS2 amounts are the ones tested in trials for people with AMD. They are not everyday amounts. Before adding a multivitamin, compare its Supplement Facts label with your AREDS2 label, and ask your pharmacist to check the totals.
Keep a list and share it
NEI's FAQ notes that "high-dose nutritional supplements can sometimes interfere with medications and compete with other vital nutrients for absorption into the body." NEI suggests that anyone considering the formulas "should make a list of all the medications they take," including "supplements and over-the-counter drugs."
ODS gives the same advice: "Keep a complete record of any dietary supplements and medicines you take." It offers a printable form called "My Dietary Supplement and Medicine Record." ODS also says to get your provider's approval before combining supplements with prescribed medicines. If you take a blood thinner, antibiotics or a water pill, our articles on AREDS2 and blood thinners and AREDS2 side effects and interactions list what to raise.
What about combined AREDS2 plus multivitamin products?
Some products put both in one softgel. For example, PreserVision AREDS 2 Formula + Multivitamin lists all six AREDS2 amounts per day along with vitamins D and K, several B vitamins, and minerals such as magnesium and selenium. Because it lists vitamin K, it is worth mentioning to your doctor if you take warfarin. Our label comparison shows how it lines up with other eye vitamins.
Whether you use one combined product or two separate ones, the basic rule is the same: check the total amounts from every product you take, including fortified foods. We do not recommend a particular product. Your eye doctor or pharmacist can help you decide which setup fits your health and medicines.
Frequently asked questions
Should I take my multivitamin and AREDS2 at the same time?
The sources we reviewed do not give a set schedule for taking the two together. ODS does note that 25 mg or more of iron taken with zinc can lower zinc absorption, so if your multivitamin contains iron, ask your pharmacist about timing.
Can I stop my multivitamin and just take AREDS2?
NEI says the AREDS2 formula does not substitute for a multivitamin. The formula contains only six nutrients. Whether you need a multivitamin is a question for your doctor.
My multivitamin has zinc. Is that a problem?
It adds to your total. The AREDS2 formula's 80 mg of zinc is already twice the adult UL of 40 mg, which ODS says does not apply to people receiving zinc for medical treatment, who should be under a physician's care. Show your doctor both labels so the total zinc is part of the conversation.
Does a multivitamin "for eyes" count as AREDS2?
Not unless the label lists the AREDS2 amounts. Some eye vitamins contain much lower amounts. Check the Supplement Facts panel, not the front of the bottle. Our science page lists the doses used in the trials.
