What Is a Good Vitamin A Brand? 10 Picks to Compare 🧡
A good vitamin A brand clearly states the nutrient’s form and dose, provides trustworthy quality information, and offers a product that fits your needs—not just a sky-high dose. Brands such as Nature Made, NOW Foods, Solgar, Carlson, and Thorne are worth comparing, but check each product’s current label and independent verification before buying.
Here’s the twist: many people don’t need a standalone vitamin A supplement at all. Vitamin A is found in foods such as eggs, dairy, sweet potatoes, and carrots, while too much preformed vitamin A can be harmful—especially during pregnancy.
We’ve seen how easy it is to focus on a familiar brand name and overlook the details that matter more: retinyl palmitate versus beta-carotene, the amount per serving, and whether a multivitamin or cod liver oil already adds vitamin A to your daily total. So, which brands make the shortlist—and what should you check before choosing one?
Key Takeaways
- Choose a transparent product, not simply a famous brand. Check the vitamin A form, dose in mcg RAE, serving size, ingredients, and product-specific quality verification.
- Food is a sensible starting point for most people. Adults generally need 700 mcg RAE daily for women and 900 mcg RAE for men from all sources.
- Avoid casually stacking supplements. The adult upper limit for preformed vitamin A is 3,000 mcg RAE per day; pregnancy and some medications call for extra caution.
- Compare real products and current labels: Nature Made, NOW Foods, Solgar, Carlson, and Thorne.
- Ask a healthcare professional before supplementing if you’re pregnant, take retinoid medication, have liver or absorption concerns, or are considering beta-carotene supplements and smoke or used to smoke.

⚡️ Quick Tips and Facts: Choosing a Vitamin A Brand
A good vitamin A brand is not simply the one with the biggest dose or the flashiest “premium” label. We look for an appropriate form and dose, transparent ingredients, trustworthy quality controls, and a real reason to supplement.
| Quick check | What to look for |
|---|---|
| Form | Preformed vitamin A (retinol or retinyl palmitate) or provitamin A carotenoids such as beta-carotene |
| Dose | A clearly stated amount in mcg RAE, not just a large IU number |
| Quality | Verifiable independent testing or certification, such as USP Verified or NSF certification where applicable |
| Need | A clinician’s recommendation or a practical reason, such as a diagnosed deficiency or limited dietary intake |
| Safety | Avoid stacking high-dose vitamin A products, especially during pregnancy or when using retinoid medications |
- Adults generally need 700 mcg RAE daily for women and 900 mcg RAE daily for men. These are total-intake targets from food and supplements, not suggested supplement doses. NIH Office of Dietary Supplements
- The adult upper limit for preformed vitamin A is 3,000 mcg RAE per day from all sources. Beta-carotene from food is not subject to the same upper limit, but high-dose beta-carotene supplements are not appropriate for everyone. NIH ODS
- Food first is a sensible default. Carots and sweet potatoes provide beta-carotene; eggs and dairy provide preformed vitamin A. A supplement can be useful when there’s a specific need, but “more” is not a bonus round.
- If you’re comparing vitamin brands, our guide to whether Nature Made is a good vitamin brand explains how to interpret quality claims.

The question we’ll keep coming back to: Which product is a good brand for you—and do you need a stand-alone vitamin A supplement at all?
🧭 Vitamin A at a Glance: What It Does and Where It Comes From
Vitamin A is a group of fat-soluble compounds that support normal vision, immune function, growth, reproduction, and the maintenance of tissues. It also helps cells develop and specialize. Those are essential jobs; they don’t mean a vitamin A capsule will treat an eye condition or turn a skincare routine into a magic trick. NIH Office of Dietary Supplements
There are two main dietary forms:
| Form | Common sources | How the body uses it |
|---|---|---|
| Preformed vitamin A | Liver, fish, eggs, dairy, fortified foods; supplements may use retinyl palmitate or retinyl acetate | Absorbed as active vitamin A; excessive intake can accumulate |
| Provitamin A carotenoids | Carots, pumpkin, sweet potato, spinach, kale; supplements often use beta-carotene | Converted into vitamin A as the body needs it, with conversion varying among people |
Vitamin A is fat-soluble, so it is absorbed along with dietary fat. Taking a supplement with a meal may help absorption, but it does not make an excessive dose safe. NIH ODS
Preformed vitamin A vs. beta-carotene
A supplement label can list “vitamin A” without making the choice obvious. Check the ingredient panel for the source:
- Retinyl palmitate or retinyl acetate: preformed vitamin A. It can be appropriate when recommended, but high ongoing intake raises toxicity concerns.
- Beta-carotene: a provitamin A carotenoid found in colorful plant foods and some supplements. The body converts it to vitamin A; conversion is not identical for everyone.
- Cod liver oil: may provide vitamin A, but the amount varies by product. It also supplies other nutrients, so check the full label rather than treating it as a single-nutrient vitamin A product.
For most people choosing a supplement without a diagnosed deficiency, a food-forward approach and avoiding high-dose preformed vitamin A are prudent. Smokers and people with a history of smoking should avoid high-dose beta-carotene supplements unless a healthcare professional specifically recommends them; large trials found increased lung-cancer risk in certain high-risk groups. National Cancer Institute
How much vitamin A do you need?
Recommended intake is usually stated in micrograms of retinol activity equivalents (mcg RAE). It accounts for differences in how the body uses preformed vitamin A and carotenoids.
| Group | Recommended daily intake |
|---|---|
| Adult women | 700 mcg RAE |
| Adult men | 900 mcg RAE |
| Pregnancy, ages 19–50 | 770 mcg RAE |
| Breastfeeding, ages 19–50 | 1,300 mcg RAE |
These are total daily amounts from food and supplements. Needs differ by age and life stage; see the NIH vitamin A fact sheet for detailed tables.
🏆 What Makes a Good Vitamin A Brand?
We assess brands by what they disclose and verify—not by how many times the bottle says “advanced,” “pure,” or “doctor-formulated.” Those phrases may sound reassuring, but the useful details are the dose, form, testing, and manufacturing information.
Quality testing, clear labels, and ingredient transparency
A strong label should let you answer these questions without a magnifying glass and a detective hat:
- What form of vitamin A is in the product?
- How much does one serving provide in mcg RAE?
- What is the serving size? One softgel, several drops, or multiple capsules?
- Are other vitamins included? Cod liver oil and combination formulas can add vitamin D or other nutrients.
- Can you verify testing or certification? Look for a named program and check its listing, rather than relying on a vague “tested” claim.
- Do allergens and excipients fit your needs? Check for fish, soy, gelatin, beeswax, oils, and other ingredients.
In the United States, dietary supplements are regulated differently from prescription medicines. The FDA does not approve supplements for safety and effectiveness before they are marketed, though manufacturers must follow applicable requirements, including current good manufacturing practices. FDA: Dietary Supplements
USP, NSF, and other third-party certifications
Independent verification can help confirm product quality attributes, but it does not establish that a supplement is necessary or right for you.
| Quality signal | What it can help verify | What it does not prove |
|---|---|---|
| USP Verified | Product contains listed ingredients in declared amounts, meets certain contaminant limits, and is made under quality processes | That the product treats a condition or is suitable for every person |
| NSF certification | Depending on the program, ingredient identity, label accuracy, and contaminant or manufacturing checks | That a supplement is FDA-approved |
| UL or other testing claims | May indicate facility or product testing; check exactly what is certified | That every product from a brand has the same certification |
| “Third-party tested” | Potentialy useful if the lab, scope, and results are disclosed | Much unless the brand explains what was tested and how |
Nature Made says USP has verified certain products and quality attributes; do not assume every Nature Made item, or a vitamin A product specifically, carries USP verification. Verify the particular product using the USP Verified products directory and the product’s current label. Brand claims and product availability can change.
🔎 Our Top Vitamin A Brand Picks
A note on these picks: Product formulas, labels, certifications, and availability can change. We recommend checking the current label and any certification database before buying. We also distinguish between a brand that sells supplements generally and a product that actually provides vitamin A in a clearly specified form and dose.
A competitor review from Healthline’s vitamin A supplement roundup calls its selections “a great starting point for choosing a high quality, third-party-verified vitamin A supplement.” That’s a useful perspective, but a roundup isn’t a substitute for checking your own dose, risk factors, and product label. Here’s how we’d compare commonly discussed brands and product types.
| Brand/product | Vitamin A source or format | Best suited to | Watch-outs |
|---|---|---|---|
| Nature Made Vitamin A | Confirm current product label | Shoppers seeking an established mainstream brand | Confirm product availability, dose, form, and certification |
| NOW Foods Vitamin A | Some products use fish liver oil and preformed vitamin A | Those seeking a clearly labeled single-nutrient option | Dose may be high relative to daily needs |
| Solgar Dry Vitamin A | Check current label | People seeking a dry-format option | Verify dose, form, and allergens |
| Carlson Vitamin A | Product forms vary; cod liver oil products may include other nutrients | Those considering fish-oil-based products | Check vitamin D and total vitamin A intake |
| Thorne Beta-Carotene | Beta-carotene product options vary | Those seeking a carotenoid-based option | High-dose beta-carotene is not a fit for everyone |
| Life Extension Natural Beta-Carotene | Beta-carotene | Adults who have discussed the need with a clinician | Smoking history and dose matter |
| Pure Encapsulations Beta Carotene | Beta-carotene product options vary | Those looking for a practitioner-oriented brand | Verify current formula and suitability |
| Garden of Life Vitamin Code Raw Vitamin A | Verify current product and label | Shoppers interested in whole-food-style products | Check whether the exact vitamin A product is currently available and its actual dose |
| Swanson Vitamin A | Product formulas vary; some include preformed vitamin A | Those comparing straightforward supplement formats | Verify dose, source, and allergens |
| Kirkland Signature Vitamin A | Product availability and formulation may vary | Costco shoppers comparing current offerings | Confirm a vitamin A-only product is available in your region |
1. Nature Made Vitamin A
Nature Made is a familiar supplement brand, but brand reputation alone doesn’t answer whether a specific vitamin A product is a good choice. Its site describes quality commitments and USP verification for certain products; check the specific product listing and certification rather than applying that claim across the entire range. Nature Made · USP product directory
What we like
- Established U.S. supplement brand with product information available through its official site.
- Some Nature Made products carry USP verification; the status is product-specific.
- A reasonable candidate when the exact dose and ingredients suit your needs.
What to verify
- Whether Nature Made currently sells a stand-alone vitamin A product where you shop.
- Whether it uses preformed vitamin A or beta-carotene.
- Whether that particular bottle is USP Verified.
Our take: Consider Nature Made when its current product label is transparent and its dose matches professional guidance. For context on brand-wide quality claims, see our guide: Is Nature Made a good vitamin brand?
2. NOW Foods Vitamin A
NOW Foods offers a broad supplement range, including vitamin A products in some markets. Healthline’s roundup lists NOW Foods Vitamin A 10,000 IU as a single-nutrient option. A label displaying 10,000 IU is not automatically a “better” dose; check its mcg RAE equivalent and compare it with your total intake.
What we like
- Product information and ingredient details are available from the brand.
- A single-nutrient product can make it easier to see what you’re taking.
- May suit someone whose clinician has recommended a specific amount.
Potential drawback
- A high-potency product can exceed ordinary daily needs, especially when combined with food, a multivitamin, or cod liver oil.
- Ingredient sources and allergen statements should be checked on the current label.
Our take: A brand to compare, not a blanket recommendation to take a high-dose vitamin A capsule daily.
3. Solgar Dry Vitamin A
Solgar sells various vitamin and mineral supplements. If considering its dry vitamin A product, inspect the current label for the source, dose, serving size, and excipients. “Dry” describes the format; it does not by itself establish superior absorption or safety. Solgar product site
What we like
- A dry format may be convenient for people who prefer not to take oil-based softgels.
- Solgar provides product information through its official site.
Potential drawback
- Formula details may vary by product and region.
- A preformed vitamin A product still requires attention total intake.
Our take: Compare the label against your needs rather than choosing based on format or brand name alone.
4. Carlson Vitamin A
Carlson is known for fish-oil products, including cod liver oil options. Those products can provide vitamin A alongside omega-3 fats and sometimes vitamin D. The blend may be useful for someone who wants those nutrients for a specific reason, but it can complicate dose tracking. Carlson Labs
What we like
- Fish-oil products may combine nutrients in one serving.
- The brand provides product details that can help consumers compare formats.
Potential drawback
- Cod liver oil is not the same as a dedicated vitamin A supplement.
- Check total vitamin A and vitamin D from all sources, as well as fish allergies.
Our take: Choose a cod liver oil product for its full nutrient profile—not simply because the label mentions vitamin A.
5. Thorne Beta-Carotene
Thorne sells a range of practitioner-oriented supplements. Its carotenoid options may appeal to people seeking a plant-derived source, but check the current ingredient panel: a beta-carotene supplement is not interchangeable with preformed vitamin A. Thorne
What we like
- A beta-carotene format may fit some dietary preferences.
- The brand publishes product and quality information.
Potential drawback
- High-dose beta-carotene supplements should be avoided by smokers and people with a history of smoking unless specifically advised by a clinician. NCI
- Individual conversion of beta-carotene to vitamin A varies.
Our take: A possible option only after reviewing dose, smoking history, and clinical need.
6. Life Extension Natural Beta-Carotene
Life Extension offers nutritional supplements, including carotenoid products. “Natural” is not a dose, a certification, or proof of a health benefit, so look at the active ingredient and amount per serving. Life Extension
What we like
- Beta-carotene can suit people seeking a provitamin A source.
- The company provides product information for consumers to review.
Potential drawback
- Supplemental beta-carotene is not a universal substitute for a varied diet.
- People who smoke or formerly smoked should discuss supplements with a clinician.
Our take: Compare the dose and testing information against other brands; don’t let the word “natural” do all the decision-making.
7. Pure Encapsulations Beta Carotene
Pure Encapsulations offers practitioner-oriented products, including carotenoid and combination formulas. Healthline includes a vision-support formula in its roundup, but that type of product may contain multiple active ingredients and a substantial amount of vitamin A. Pure Encapsulations
What we like
- Product information can be useful for clinician-guided selection.
- Some products are designed for people who want a broader nutrient blend.
Potential drawback
- Combination products make it easier to double up on nutrients unintentionally.
- A vision formula is not a treatment for eye disease; discuss eye symptoms with an eye-care professional.
Our take: Best considered with a clinician when there’s a specific reason for a multi-ingredient product.
8. Garden of Life Vitamin Code Raw Vitamin A
Garden of Life sells whole-food-style supplements, but verify that the exact Vitamin Code vitamin A product is currently available and inspect its current formulation. Company-wide organic, non-GMO, or manufacturing claims do not automatically apply to every product or establish a vitamin A dose. Garden of Life
A recent chemical-sourcing article highlights Garden of Life’s broader certification and sourcing approach, but does not identify a specific vitamin A product or provide its dose. That’s a useful reminder: brand-level praise is not product-level evidence. Check the bottle and certification listings.
What we like
- The brand provides product and ingredient information.
- Some products may fit shoppers who prefer whole-food-style formulations.
Potential drawback
- Confirm the actual vitamin A source, amount, and certification for the specific item.
- “Whole food” does not mean risk-free or automatically appropriate.
9. Swanson Vitamin A
Swanson sells several vitamin A products, and formulas can differ. Healthline lists both a beta-carotene option and a preformed vitamin A product in its roundup. Those are meaningfully different choices, so use the exact product name and label when comparing. Swanson
What we like
- More than one vitamin A source or format may be available.
- Product pages can help clarify ingredients and serving size.
Potential drawback
- Some formulas may contain fish-derived ingredients, soy, or beeswax; check allergens and vegan suitability.
- A high percentage of Daily Value is not a reason to take a product without a need.
Our take: Compare the exact formula, not just “Swanson vitamin A.”
10. Kirkland Signature Vitamin A
Kirkland Signature product availability changes by location and over time. We did not find enough product-specific information to recommend a particular Kirkland vitamin A product or dose. Check the Kirkland Signature catalog and the current bottle label before treating the brand as a vitamin A option.
What we like
- Costco’s house brand is familiar to many shoppers.
- Product labels can be reviewed before purchase.
What to verify
- That the product is a stand-alone vitamin A supplement currently available in your region.
- The source, dose, serving size, allergens, and any independent certification.
Our take: Don’t assume a brand’s general supplement presence means it has a vitamin A product that fits your needs.
📊 Vitamin A Supplement Brand Comparison
This comparison prioritizes the details that matter more than marketing: source, dose clarity, and whether the product is a simple nutrient or a multi-ingredient formula. Always use the current product label; formulas can change.
| Option | Type to look for | Best reason to consider it | Main caution |
|---|---|---|---|
| Nature Made | Stand-alone product if currently available | Familiar brand; check product-specific USP status | Do not assume every product is verified |
| NOW Foods Vitamin A | Preformed vitamin A softgel in some listings | Single-nutrient format | May be high-dose |
| Solgar Dry Vitamin A | Dry-format product | Alternative to oil-based softgels | Confirm source and dose |
| Carlson cod liver oil | Fish-liver oil with other nutrients | Interest in the whole oil profile | Adds vitamin D and other nutrients |
| Thorne beta-carotene | Carotenoid supplement | Plant-derived provitamin A option | Smoking history matters |
| Life Extension beta-carotene | Carotenoid supplement | Another brand to compare | Check dose and testing |
| Pure Encapsulations formula | Single nutrient or combination, depending on item | Practitioner-guided selection | Combination formulas can add up |
| Garden of Life Vitamin Code | Confirm exact product | Whole-food-style product preference | Verify exact product and formulation |
| Swanson | Multiple product types may exist | Compare specific formulas | Allergen and dose differences |
| Kirkland Signature | Confirm current catalog | Convenient if a fitting product exists | Product availability may vary |
Our practical shortlist: If you have a clinician-recommended need, compare the exact product’s form and dose first. If you are shopping without a diagnosed need, start with food intake and avoid high-dose products until you’ve reviewed your total intake with a healthcare professional.
🛒 How to Choose a Vitamin A Supplement for Your Needs
Use this step-by-step checklist before buying. It’s less glamorous than letting the bottle choose you, but much more useful.
- Clarify why you’re considering vitamin A. Is a clinician treating a confirmed deficiency, or are you hoping for general “immune” or skin support?
- Review your current intake. Include multivitamins, fortified foods, cod liver oil, and any standalone vitamin A.
- Choose the form deliberately. Check whether it is preformed vitamin A or beta-carotene.
- Compare the dose in mcg RAE. IU alone can be confusing because conversion depends on the source.
- Review the full ingredient list. Check allergens, added vitamins, oils, gelatin, and serving size.
- Verify quality claims. Look up product-specific certifications; don’t rely on a logo or “tested” wording alone.
- Ask a clinician if you have risk factors. This is especially important for pregnancy, liver disease, retinoid medication use, or smoking history.
If a multivitamin seems like a better fit than a single nutrient, compare options in our multivitamin supplements guide. A multivitamin can also make accidental “nutrient stacking” easier, so check the label carefully. The featured video makes a similar point: multivitamins may help fill gaps, but they do not replace a nutritious diet, and taking overlapping products can lead to excess or interactions.
Retinol, retinyl palmitate, or beta-carotene?
| Label ingredient | Category | Key consideration |
|---|---|---|
| Retinol | Preformed vitamin A | Counts toward the upper limit for preformed vitamin A |
| Retinyl palmitate | Preformed vitamin A | Common supplement form; excess intake can be harmful |
| Retinyl acetate | Preformed vitamin A | Also counts toward the preformed vitamin A upper limit |
| Beta-carotene | Provitamin A carotenoid | Conversion varies; high-dose supplements are not suitable for some people |
For a person who eats a varied diet, beta-carotene-rich foods are often an easy way to include provitamin A. A supplement may be considered in specific circumstances, but the right choice depends on your health and intake—not a universal “best form.”
Understanding IU, mcg RAE, and serving size
IU and mcg RAE are not interchangeable numbers without context. The conversion depends on whether vitamin A comes from retinol or beta-carotene. Look for the amount in mcg RAE and read whether the listed amount applies to one capsule, several capsules, or a liquid serving. NIH ODS
Also check % Daily Value carefully. A supplement providing a high percentage of the Daily Value isn’t automatically more effective; it may simply provide more than you need.
Softgels, capsules, liquids, and multivitamins
| Format | Potential plus | Potential drawback |
|---|---|---|
| Softgel | Convenient; often oil-based | May contain fish, gelatin, or soy |
| Capsule/tablet | Easy to handle and store | May include more excipients; check dose |
| Liquid drops | Flexible serving sizes | Measuring accurately can be harder |
| Multivitamin | Combines nutrients in one product | Can duplicate vitamin A from other supplements |
Fat in a meal may support absorption of fat-soluble vitamin A. But don’t add a high dose because a product is “better absorbed”—absorption does not erase toxicity risk.
Vegan, allergen, and dietary considerations
- Vegan: Beta-carotene is generally the plant-derived route, but check the complete formulation and capsule materials.
- Fish allergy: Avoid fish liver oil and cod liver oil products.
- Soy allergy: Check for soybean oil or soy lecithin.
- Gelatin-free: Look for vegetarian capsule materials and confirm the label.
- Pregnancy: Do not self-prescribe high-dose preformed vitamin A; discuss supplements with your prenatal care team.

🥕 Food Sources vs. Vitamin A Supplements
Most people can get vitamin A through a balanced eating pattern. Animal foods supply preformed vitamin A; colorful vegetables and fruits supply carotenoids that the body can convert. NIH ODS
| Food | Vitamin A form or contribution |
|---|---|
| Beef liver | Very concentrated source of preformed vitamin A |
| Eggs and dairy | Preformed vitamin A |
| Fortified milk or cereal | Amount depends on product |
| Sweet potatoes | Beta-carotene |
| Carots and pumpkin | Beta-carotene |
| Spinach, kale, and other dark leafy greens | Carotenoids |
| Red and orange peppers | Carotenoids |
A useful kitchen tip: Carotenoids are fat-soluble, so serve vegetables with a source of fat, such as olive oil, nuts, seeds, or avocado. That’s a cooking strategy, not a reason to take an extra supplement.
Liver deserves a special mention: it can provide substantial preformed vitamin A. If you eat liver frequently, take a multivitamin, or use cod liver oil, ask a clinician or registered dietitian to help assess your overall intake—especially during pregnancy.
⚠️ Vitamin A Safety, Side Effects, and Interactions
Vitamin A is essential, but preformed vitamin A can build up in the body. Too much over time may cause harm. The risk is most relevant when high-dose supplements overlap with other sources or when someone has a health condition or medication that changes vitamin A handling.
Daily upper limits and signs of excess
The adult tolerable upper intake level is 3,000 mcg RAE per day of preformed vitamin A. The upper limit applies to preformed vitamin A, not beta-carotene from food. NIH ODS
| Possible excess-intake effects | Why to take them seriously |
|---|---|
| Headache, nausea, dizziness | Can occur with excessive intake |
| Blurred vision or poor coordination | Needs prompt medical assessment |
| Dry or peeling skin, hair changes | May occur with chronic excess |
| Bone or liver problems | Risk with prolonged high intake |
| Pregnancy-related fetal harm | Excess preformed vitamin A can be dangerous during pregnancy |
Stop taking a non-prescribed supplement and contact a healthcare professional if you suspect excessive intake. Seek urgent medical care for severe or rapidly worsening symptoms.
Pregnancy, planning to conceive, and breastfeeding
High intake of preformed vitamin A during pregnancy can cause birth defects. If you’re pregnant, planning a pregnancy, or breastfeeding, don’t add a standalone vitamin A supplement without guidance from your prenatal clinician. Prenatal vitamins differ ingredients and amounts, so review the full label rather than doubling up.
Beta-carotene in foods is a different matter from high-dose preformed vitamin A supplements, but it’s still best to discuss any supplement plan with your care team. NIH ODS
Medications and health conditions to discuss with a clinician
Get professional advice before supplementing if you:
- Take oral retinoids such as isotretinoin or acitretin.
- Have liver disease or a condition that affects fat absorption.
- Smoke or have a history of smoking and are considering beta-carotene supplements.
- Take a multivitamin, cod liver oil, or another product containing vitamin A.
- Are pregnant, breastfeeding, or planning to conceive.
- Have been told you have a nutrient deficiency or a chronic health condition.
Medication and supplement interactions depend on the particular drug, dose, and health history. Bring the bottle or a clear photo of the Supplement Facts panel to your clinician or pharmacist.
💡 When to Ask a Healthcare Professional About Vitamin A
A healthcare professional can help decide whether you need a supplement, which form fits, and how to avoid excessive total intake. Ask before starting if:
- You have symptoms or a medical reason to suspect deficiency.
- You’re pregnant, planning pregnancy, or breastfeeding.
- You use prescription retinoids or take other supplements containing vitamin A.
- You eat liver often or use cod liver oil.
- You smoke or have smoked and are considering a beta-carotene supplement.
- You have liver disease, digestive conditions, or a history of nutrient malabsorption.
Vitamin A deficiency and toxicity are not situations to diagnose by guessing at a bottle. A clinician can interpret your diet, symptoms, medications, and—when appropriate—laboratory findings together. For broader education, browse our essential vitamins and health supplements guides.
