Medications That May Deplete BETA-CAROTENE
Vitamin A supports vision, immune function, and skin health. See which medications carry a reported association, how strong the evidence is, and what to discuss with your pharmacist.
Vitamin A supports vision, immune function, and skin health.
Common food sources: Liver and fish oils; Dairy and eggs; Orange and yellow vegetables (as beta-carotene); Leafy greens.
Ask your provider before supplementing vitamin A — status testing is not routine, and intake from food plus multivitamins is often already adequate.
Caution: Avoid high-dose vitamin A in pregnancy or when trying to conceive unless a clinician directs it.

Cholestyramine
Insignificant DepletionBrand names include Questran
Cholestyramine (Questran) and colestipol (Colestid) can reduce absorption of fat-soluble vitamins, including beta-carotene. Serum levels of beta-carotene can be reduced, but this is probably only in proportion to the lowering of cholesterol (on which beta-carotene is transported). Supplements are not usually needed.
Beta-carotene is a plant pigment your body converts into vitamin A, which supports healthy vision, skin, and immune function. Cholestyramine works in your gut by binding to bile acids, and because beta-carotene is a fat-soluble nutrient, some of it may get caught up in that process and absorbed a little less efficiently. Here is the reassuring part: any dip in blood levels appears to be tied to the expected drop in cholesterol (which normally carries beta-carotene through the bloodstream), not a true shortage of the nutrient itself. For most people on cholestyramine, a supplement is not needed, but feel free to mention it to your pharmacist or doctor if you have concerns.

Colchicine
Insignificant DepletionBrand names include Colsalide Improved, Mitigare, Colcrys
Limited evidence suggests that short-term treatment with colchicine 1.9-3.9 mg daily can reduce absorption and serum levels of beta-carotene. Theoretically. this is due to disruption of intestinal mucosal function. Long-term use of 1 to 2 mg daily does not affect beta-carotene levels. Advise patients that this is unlikely to be clinically significant.
Beta-carotene is a pigment found in colorful vegetables that your body converts into vitamin A, which supports healthy vision, skin, and immune function. At higher doses used short-term, colchicine can mildly interfere with the gut lining's ability to absorb nutrients, and some studies showed a small dip in beta-carotene levels. That said, people taking the typical long-term dose of 1 to 2 mg daily do not appear to see any meaningful change, and this is generally considered an insignificant concern for most patients. No action is needed for the majority of people, but if you have questions about your diet or any supplements, your pharmacist is a great place to start.

At higher doses used short-term, colchicine may mildly interfere with how the intestinal lining absorbs beta-carotene, but at the typical long-term doses most people take, studies have not found a meaningful drop in levels. Given the insignificant rating here, this is not something most patients need to act on, though you are always welcome to mention it to your pharmacist if you have questions.

Colestipol
Insignificant DepletionBrand names include Colestid
Cholestyramine (Questran) and colestipol (Colestid) can reduce absorption of fat-soluble vitamins, including beta-carotene. Serum levels of beta-carotene can be reduced, but this is probably only in proportion to the lowering of cholesterol (on which beta-carotene is transported). Supplements are not usually needed.
Beta-carotene is a plant pigment your body converts into vitamin A, which supports healthy vision, skin, and immune function. Colestipol works in the gut to trap bile acids and lower cholesterol, and because beta-carotene is a fat-soluble nutrient that rides along with cholesterol in the bloodstream, lower cholesterol levels can mean slightly lower beta-carotene readings on a blood test. Researchers believe this reflects the cholesterol drop itself rather than a true nutritional shortfall, which is why this is rated insignificant. For most people taking colestipol, no extra beta-carotene is needed, but if you have questions about your diet or lab results, your pharmacist or doctor is a great first call.

Mineral Oil
Insignificant DepletionBrand names include Kondremul Plain
Mineral oil is a laxative and reduces absorption of fat-soluble vitamins, including beta-carotene. This is not likely to be clinically significant when mineral oil is used for 4 months or less.
Beta-carotene is a plant pigment your body converts into vitamin A, which supports healthy vision, skin, and immune function. Because mineral oil is not digested or absorbed, it can carry fat-soluble nutrients like beta-carotene through the gut before they get a chance to absorb properly. That said, for short-term use of four months or less, this effect is considered insignificant for most people, so a supplement is generally not needed. If you use mineral oil regularly over a longer stretch, it is worth mentioning to your pharmacist just to be safe.

Neomycin
Insignificant DepletionBrand names include Mycifradin, Neo-Fradin, Myciguent
Oral neomycin sulfate in doses of 4-12 grams per day causes malabsorption and can reduce beta-carotene absorption. However, this is not likely to be clinically significant with short-term neomycin use.
Beta-carotene is a plant pigment your body converts into vitamin A, which supports your vision, immune system, and skin. Neomycin, especially at the high doses sometimes used to prepare the gut before surgery, can interfere with how your intestines absorb nutrients like beta-carotene. That said, this effect is considered insignificant, and short-term use at typical doses is not expected to cause any real problem for most people. No action is needed, but if you have questions about your specific situation, your pharmacist or doctor is a great place to start.

Niacin, Simvastatin
Insignificant DepletionBrand names include Simcor
Clinical research shows that simvastatin can reduce serum levels of circulating beta-carotene, but this is probably only in proportion to the lowering of cholesterol (on which beta-carotene is transported). Supplements are not usually needed.
Beta-carotene is a plant pigment your body converts into vitamin A, which supports healthy vision, skin, and immune function. Because beta-carotene hitches a ride in the bloodstream on cholesterol particles, simvastatin's job of lowering cholesterol can bring beta-carotene levels down a little along with it. That said, this is rated as insignificant, meaning the drop tends to track with the cholesterol reduction rather than reflecting a true shortage in your body. Most people on simvastatin do not need to do anything about this, but if you have questions or eat a very limited diet, your pharmacist or doctor is a great person to check with.

Orlistat
Major DepletionBrand names include Xenical, Alli
Orlistat blocks the enzyme that breaks down fat for absorption. Theoretically, in addition to reducing fat absorption, it might also reduce absorption of fat-soluble vitamins like beta-carotene. Recommend that patients take a multivitamin supplement, and separate the dosing time by at least 2 hours from orlistat.
Orlistat works by blocking fat digestion in your gut, which is exactly how it helps with weight loss. The catch is that beta-carotene, a nutrient your body converts into vitamin A to support your eyes, skin, and immune system, needs fat to be absorbed properly. Because orlistat cuts fat absorption so significantly, it can pull beta-carotene out of the picture too. Given the major rating here, most long-term users are advised to take a daily multivitamin, just be sure to take it at least two hours apart from your orlistat dose so it can actually absorb. Ask your pharmacist or doctor what works best for your routine.

Oral neomycin sulfate in doses of 4-12 grams per day causes malabsorption and can reduce beta-carotene absorption. However, this is not likely to be clinically significant with short-term neomycin use.
Beta-carotene is a plant pigment your body converts into vitamin A, which supports healthy vision, skin, and immune function. The neomycin component of this combination can interfere with how your gut absorbs certain nutrients, including beta-carotene, particularly at high doses taken over time. That said, this is rated insignificant, meaning a short course at typical doses is very unlikely to cause a real problem for most people. No action is needed for the average patient, but if you have questions about your specific situation, your pharmacist is a great first stop.

Simvastatin
Insignificant DepletionBrand names include Zocor
Clinical research shows that simvastatin can reduce serum levels of circulating beta-carotene, but this is probably only in proportion to the lowering of cholesterol (on which beta-carotene is transported). Supplements are not usually needed.
Beta-carotene is a plant pigment your body converts into vitamin A, which supports healthy vision, skin, and immune function. Simvastatin can cause a modest drop in circulating beta-carotene levels, but here is the key detail: beta-carotene travels through the bloodstream attached to cholesterol, so when simvastatin lowers your cholesterol, beta-carotene readings naturally come down a little too. This appears to be a transport effect rather than a true loss, and for most people taking simvastatin it is considered insignificant. No action is usually needed, but if you have questions about your diet or levels, your pharmacist or doctor is a good place to start.

Insignificant DepletionBrand names include Vytorin
Clinical research shows that simvastatin can reduce serum levels of circulating beta-carotene, but this is probably only in proportion to the lowering of cholesterol (on which beta-carotene is transported). Supplements are not usually needed.
Beta-carotene is an antioxidant your body converts into vitamin A, which supports your vision, immune system, and skin. Because beta-carotene hitches a ride in the bloodstream on cholesterol particles, when simvastatin does its job and brings cholesterol down, beta-carotene levels can dip a little along with it. That said, this is rated as insignificant, meaning the drop appears to be a side effect of cholesterol lowering rather than a true nutritional loss, and supplements are not considered necessary for most people taking this medication.

Sodium Phenylbutyrate, Taurursodiol
Insignificant DepletionBrand names include Relyvrio
Cholestyramine (Questran) and colestipol (Colestid) can reduce absorption of fat-soluble vitamins, including beta-carotene. Serum levels of beta-carotene can be reduced, but this is probably only in proportion to the lowering of cholesterol (on which beta-carotene is transported). Supplements are not usually needed.
Beta-carotene is a plant pigment your body converts into vitamin A, which supports healthy vision, skin, and immune function. Taurursodiol is a bile acid, and some bile acid compounds have been linked to modest reductions in how well the gut absorbs beta-carotene, since fat-soluble nutrients like this one depend on bile to get into the bloodstream. That said, any dip in beta-carotene levels seen with this type of medication appears to track with normal changes in cholesterol levels rather than representing a true depletion. This is rated insignificant, meaning most people on this medication do not need to take any action, but feel free to mention it to your pharmacist if you have questions.

Beta-carotene is something your body converts into vitamin A, which helps support your vision, immune system, and skin. The omeprazole magnesium in this combination lowers stomach acid, and there is some early thinking that less acid in the stomach could make it harder to absorb beta-carotene from supplements.

For now, most people taking this medication do not need to act on this, but if you take beta-carotene supplements and have questions, your pharmacist is a good first stop.

What drug-induced nutrient depletion means
Some medications can, over time, lower the levels of certain vitamins, minerals, or other nutrients — through reduced absorption, increased loss, or changes in how the body uses them.
Association is not deficiency
An entry here means a depletion has been reported or studied — not that it happens to everyone, or that you are deficient. Dose, duration, diet, and your own health all matter.
Evidence varies by pair
Some drug–nutrient links (like metformin and vitamin B12) are well studied; others rest on limited or preliminary research. Each entry shows the evidence rating from our licensed clinical database.
When to ask about labs
If you take an associated medication long-term, ask your healthcare provider whether monitoring is appropriate for you. Not everyone needs testing — your provider can weigh your dose, duration, and symptoms.
Don't self-supplement blindly
Supplements are not risk-free: some can interact with medications, and some (like potassium or magnesium) can be risky with kidney disease. Talk to your pharmacist before adding anything.
Never stop a medication over this
These medications are prescribed for good reasons, and the benefit usually far outweighs a manageable nutrient consideration. Any change belongs in a conversation with your prescriber.
Food first, usually
For many nutrients, a varied diet covers the gap. Each entry lists common food sources; a supplement is a decision to make with your pharmacist or provider, not a default.
