BETA-CAROTENE

Insignificant Depletion

BILE ACID SEQUESTRANTS

Bile acid sequestrants may modestly reduce absorption of beta-carotene.

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.
Taking Colestipol? A supplement is not needed for most patients. ⓘ
Dr. Brian Staiger, Pharm.D explains

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.

What Vitamin A does & food sources

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

HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.

What to discuss with your clinician

Ask your provider before supplementing vitamin A — status testing is not routine, and intake from food plus multivitamins is often already adequate.

HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.

Supplement considerations

Vitamin A is fat-soluble and accumulates; excess is harmful (and dangerous in pregnancy). Prefer food sources unless a clinician advises otherwise.

Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

PHOSPHATE SALTS

Insignificant Depletion

COLESTIPOL (Colestid)

Theoretically, taking colestipol might increase the risk of hypophosphatemia and associated adverse effects; colestipol and phosphate intake should be separated by at least 2 hours.
Colestipol can bind phosphate in the gut. It also reduces absorption of vitamin D, which normally acts to increase gastrointestinal absorption and kidney reabsorption of phosphate. In most people taking colestipol, serum phosphate levels remain within normal limits. Most people taking colestipol are unlikely to need phosphate supplements unless their dietary intake is low.
Taking Colestipol? A supplement is not needed for most patients. ⓘ
Dr. Brian Staiger, Pharm.D explains

Phosphate is a mineral your muscles, bones, and cells need for energy and structure. Colestipol works by binding things in your gut to lower cholesterol, and it can grab onto phosphate and vitamin D along the way, which may slightly reduce how much phosphate your body absorbs. That said, research shows blood phosphate levels stay normal for most people taking this medication, so this is considered an insignificant concern for the average patient. If your diet is already low in phosphate-rich foods, it is worth mentioning to your pharmacist or doctor just to be sure.

VITAMIN B12

Insignificant Depletion

BILE ACID SEQUESTRANTS

Bile acid sequestrants might reduce vitamin B12 absorption, but this is unlikely to be clinically significant.

These resins can decrease gastrointestinal (GI) absorption of vitamin B12 by binding intrinsic factor and vitamin B12-intrinsic factor complexes. However, absorption isn't completely prevented. It's unlikely that this interaction will deplete body stores of vitamin B12 unless there are other factors contributing to deficiency. In a group of children treated with cholestyramine for up to 2.5 years, there was no change in serum vitamin B12 levels. Routine supplements aren't necessary.
Taking Colestipol? A supplement is not needed for most patients. ⓘ
Dr. Brian Staiger, Pharm.D explains

Vitamin B12 is something your nerves and red blood cells genuinely depend on, so it is worth knowing how colestipol fits in. Colestipol works in your gut by binding to bile acids, but it can also interfere with a special carrier protein called intrinsic factor that normally shuttles vitamin B12 into your bloodstream. That said, this interference does not fully block absorption, and studies have not shown meaningful drops in vitamin B12 levels even in people using similar medications for years. For most people taking colestipol, this is not something to worry about, though if you have other reasons your B12 might already be low, it is worth mentioning to your pharmacist or doctor.

What Vitamin B12 does & food sources

Vitamin B12 supports red blood cell formation, nerve function, and DNA synthesis.

Common food sources:

  • Meat, poultry, and fish
  • Eggs and dairy products
  • Fortified cereals and nutritional yeast

HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.

What to discuss with your clinician

If you take an associated medication long-term, ask your healthcare provider whether checking a vitamin B12 level (sometimes with methylmalonic acid) is appropriate — especially if you notice fatigue, numbness, tingling, or memory changes.

HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.

Supplement considerations

B12 status is easy to check and low levels are usually straightforward to address, so testing before supplementing is often the sensible order. High-dose folic acid can mask a B12 deficiency, which is one reason B12 and folate questions are best sorted out together with your provider.

Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

Caution: B12 deficiency can look like other conditions — do not self-diagnose from symptoms alone.

VITAMIN E

Insignificant Depletion

BILE ACID SEQUESTRANTS

Bile acid sequestrants might reduce vitamin E levels.

Cholestyramine (Questran) and colestipol (Colestid) reduce absorption of dietary fat, so there is concern that they might reduce absorption of fat soluble vitamins, including vitamin E. Some studies suggest that the bile acid sequestrants lower vitamin E levels by 7% to 20%. But other studies have found no effect on vitamin E levels. When decreases did occur, they were often in proportion to the lowering of LDL (on which vitamin E is transported), and did not fall below the lower limit of normal (5 micrograms/mL) with up to 2 years of treatment. Routine vitamin E supplements aren't necessary, but consider them for patients who take high doses of bile acid sequestrants for several years, or who have low serum vitamin E levels.
Taking Colestipol? A supplement is not needed for most patients. ⓘ
Dr. Brian Staiger, Pharm.D explains

Vitamin E is a fat-soluble nutrient your body uses as an antioxidant to protect cells from damage. Because colestipol works in the gut by binding bile acids and reducing how much dietary fat is absorbed, it can also slightly reduce how much fat-soluble vitamin E your body takes in. That said, studies show the effect is small and levels generally stay within a normal range, so the evidence rates this as insignificant for most people. Unless you've been on a high dose for many years or your doctor has found low vitamin E levels on a blood test, a supplement is not something most patients need to worry about.

What Vitamin E does & food sources

Vitamin E is a fat-soluble antioxidant that protects cell membranes.

Common food sources:

  • Vegetable oils
  • Nuts and seeds
  • Wheat germ
  • Leafy greens

What to discuss with your clinician

Deficiency is rare; ask your provider before supplementing, particularly if you take blood thinners.

FOLIC ACID

Moderate Depletion

COLESTIPOL (Colestid)

Colestipol might interfere with folic acid absorption and reduce serum folate levels.

Colestipol can interfere with absorption of folic acid, and reduce serum folate levels. Encourage patients to maintain good dietary intake of folic acid. For information on foods that are rich in folate, see our chart.
Taking Colestipol? Monitor for depletion; a supplement is needed for some patients. ⓘ
Dr. Brian Staiger, Pharm.D explains

Colestipol is a cholesterol-lowering medication that works by binding things inside your gut so they pass out of the body rather than being absorbed, and folic acid, the B vitamin your body needs to build healthy cells and support a healthy pregnancy, can get caught up in that same process. Because colestipol acts like a sponge in your intestines, it can reduce how much folate actually makes it into your bloodstream. This is rated as moderate depletion, meaning it is worth paying attention to, and some patients do end up needing a supplement. If you have been on colestipol for a while, it is a good idea to ask your pharmacist or doctor whether your folate levels should be checked.

What Folic acid (folate) does & food sources

Folate is needed for cell division, red blood cell formation, and healthy fetal development.

Common food sources:

  • Leafy green vegetables
  • Beans, lentils, and peas
  • Fortified grains and cereals
  • Citrus fruits

HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.

What to discuss with your clinician

Ask your provider whether folate monitoring or supplementation is appropriate for you — this matters most before and during pregnancy, and with long-term use of certain seizure or arthritis medications.

HelloPharmacist pharmacist-reviewed education — separate from the licensed record above.

Supplement considerations

Folate needs are individual. With some medications (for example, methotrexate), folic acid is often prescribed deliberately on a specific schedule — follow your prescriber's instructions rather than adding your own.

Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

Caution: High-dose folic acid can mask vitamin B12 deficiency, so the two are often evaluated together.

VITAMIN A

Moderate Depletion

BILE ACID SEQUESTRANTS

Bile acid sequestrants may reduce absorption of vitamin A.

By reducing absorption of dietary fats, cholestyramine (Questran) and colestipol (Colestid) may also reduce absorption of fat-soluble vitamins such as vitamin A. Some studies have reported a fall in serum vitamin A levels, but they rarely fall below the normal range with therapy of up to 2 years' duration. Since some of the vitamin A in plasma is carried on lipids, part of this fall in plasma vitamin A levels may be due to decreased plasma lipid levels. Other studies have reported no change in plasma vitamin A levels with colestipol, up to 30 grams/day for 6 months, or cholestyramine 12 to 24 grams/day for up to 10 years. Routine vitamin A supplements aren't necessary in people taking bile acid sequestrants, but check vitamin A levels in people taking high doses for more than 2 years. For information on foods that are rich in vitamin A, see our chart.
Taking Colestipol? Monitor for depletion; a supplement is needed for some patients. ⓘ
Dr. Brian Staiger, Pharm.D explains

Vitamin A supports your vision, immune system, and skin, and colestipol may nudge levels down a bit because it works in the gut by trapping bile acids, which indirectly reduces how well your body absorbs fat-soluble nutrients like vitamin A along the way. The research is mixed though, and levels rarely drop below the normal range, even after a couple of years of use. Most people on colestipol do not need a vitamin A supplement, but if you have been on a higher dose for more than two years, it is worth asking your doctor or pharmacist whether checking your levels makes sense.

What Vitamin A does & food sources

Vitamin A supports vision, immune function, and skin health.

  • Liver and fish oils
  • Dairy and eggs

VITAMIN D

Moderate Depletion

COLESTIPOL (Colestid)

High-dose or prolonged therapy with colestipol might reduce blood levels of vitamin D.
Colestipol can reduce absorption of fat-soluble vitamins, including vitamin D. This doesn't seem to be clinically significant when up to 20 grams daily is used for up to 2 years. For information on foods that are rich in vitamin D, see our chart.
Taking Colestipol? Monitor for depletion; a supplement is needed for some patients. ⓘ
Dr. Brian Staiger, Pharm.D explains

Colestipol works by binding things in your gut to help lower cholesterol, but as a side effect it can also grab onto fat-soluble vitamins like vitamin D before your body gets the chance to absorb them. Vitamin D is what helps your body take in calcium and keep your bones and immune system working properly. At typical doses and standard treatment lengths, this interaction does not appear to be a major concern for most people, but higher doses or long-term use may be worth watching. If you have been on colestipol for a while, it is worth asking your pharmacist or doctor whether your vitamin D level should be checked.

What Vitamin D does & food sources

Vitamin D helps the body absorb calcium and supports bone, muscle, and immune health.

Common food sources:

  • Fatty fish (salmon, mackerel)
  • Fortified milk and cereals
  • Egg yolks
  • Sunlight exposure (the main natural source)

What to discuss with your clinician

A 25-hydroxyvitamin D blood test is the standard way to assess status — ask whether it is appropriate if you take an associated medication long-term, have limited sun exposure, or have bone concerns.

Supplement considerations

Vitamin D dosing varies a lot between people; some medications change how vitamin D is processed. Your provider can target a dose to your level instead of guessing.

Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

VITAMIN K

Moderate Depletion

BILE ACID SEQUESTRANTS

Bile acid sequestrants might decrease the absorption and levels of vitamin K.

By reducing absorption of dietary fats, bile acid sequestrants may also reduce absorption of fat-soluble vitamins such as vitamin K. Some studies have found no changes in vitamin K levels or prothrombin times after up to 2 years of bile acid sequestrant use. However, there are a few case reports of hypoprothrombinemia and bleeding, usually in people with other risk factors.
Taking Colestipol? Monitor for depletion; a supplement is needed for some patients. ⓘ
Dr. Brian Staiger, Pharm.D explains

Colestipol works by binding bile acids in your gut to help lower cholesterol, but that same process can reduce how well your body absorbs fat-soluble vitamins, including vitamin K, which your blood needs to clot properly. Most long-term studies have not shown meaningful drops in vitamin K levels, but a handful of cases involving unusual bleeding have been reported, usually in people who had other risk factors going on at the same time. Because the evidence is rated moderate, it is worth mentioning to your pharmacist or doctor if you take colestipol regularly, especially if you also use a blood thinner or notice any unexpected bruising.

What Vitamin K does & food sources

Vitamin K is required for normal blood clotting and contributes to bone health.

Common food sources:

  • Leafy green vegetables (spinach, kale, broccoli)
  • Vegetable oils
  • Fermented foods like natto

More about Colestipol

Understand the basics

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.

Common questions

Colestipol & nutrients: FAQs

Does Colestipol deplete BETA-CAROTENE?
Colestipol has been associated with lower BETA-CAROTENE levels in the clinical literature — see the evidence rating and details above. An association is not a guarantee: dose, duration, diet, and your own health all matter. If you take Colestipol long-term, ask your healthcare provider whether checking your BETA-CAROTENE status is appropriate.
Should I take a supplement because I take Colestipol?
Not automatically. The right first step is usually a conversation with your pharmacist or provider — they can weigh your dose and duration, decide whether testing makes sense, and recommend food-first strategies or a supplement if genuinely needed. Some supplements can interact with medications, so do not add one without checking.
Should I stop taking Colestipol?
No — never stop a prescribed medication because of a nutrient association. Colestipol is prescribed for good reasons, and nutrient considerations are usually manageable with monitoring or diet. Any change to your medication belongs in a conversation with your prescriber.
Where does this information come from?
The depletion records come from the Natural Medicines (Therapeutic Research Center) database — an evidence-graded clinical reference — and are displayed as published, with their citations. The plain-English context is written and reviewed by licensed HelloPharmacist pharmacists.
