Numerous clinical studies have highlighted potential risks associated with high-dose beta-carotene supplementation, particularly for individuals with a history of smoking. While beta-carotene is a beneficial nutrient found naturally in many foods, synthetic supplemental forms can pose a risk, especially for lung health in certain populations. As a result, finding a multivitamin that does not contain beta-caroten e has become a health priority for many.
Why Some People Must Avoid Beta-Carotene
High-dose beta-carotene supplementation has been linked to an increased risk of lung cancer in current and former smokers, as demonstrated by landmark studies like the ATBC trial. The American Academy of Family Physicians (AAFP) has also advised against taking beta-carotene supplements for the prevention of cancer and cardiovascular disease in healthy individuals. The risk appears to be dose-dependent and related specifically to supplemental forms, not the beta-carotene found in a healthy, varied diet of fruits and vegetables. This risk also extends to people with a history of exposure to asbestos. For these high-risk groups, selecting a beta-carotene-free multivitamin is a critical safety consideration.
The Modern Alternative: AREDS 2 Formulas
For those concerned about age-related macular degeneration (AMD), the Age-Related Eye Disease Study 2 (AREDS2) provides a safer alternative. The original AREDS formula contained beta-carotene, which carried a risk for smokers. The updated AREDS2 formula replaced beta-carotene with lutein and zeaxanthin, which have been shown to be effective and eliminate the lung cancer risk associated with beta-carotene supplementation in smokers. As a result, many eye health supplements on the market today, including general multivitamins designed for eye support, follow the AREDS2 guidelines.
Recommended Multivitamins Without Beta-Carotene
Some brands offer beta-carotene-free multivitamins, including those formulated for eye health following AREDS2 guidelines and general hypoallergenic options. Examples include PreserVision AREDS 2 from Bausch + Lomb, Viteyes Classic AREDS 2 Companion Multivitamin, Vitalux Advanced, and Kirkman EveryDay Multivitamin Without Vitamins A & D. A comparison of these products is provided below.

Important Considerations When Choosing a Supplement
When selecting a multivitamin without beta-carotene, it's essential to consult a healthcare professional, especially if you have a history of smoking or other health conditions. Always carefully read the label to ensure the absence of beta-carotene and understand the form of Vitamin A if present. Remember that natural beta-carotene from food is safe.
