The Best Vitamin A Supplements of 2025: Experts Reveal What to Keep Your Eye On

Affordable, accessible, straightforward, and consistent—that’s exactly why Nutricost claimed the top spot in our best vitamin brands round-up. And their vitamin A supplement upholds that reputation, delivering high quality, value, and ease of use.

Each one-capsule serving delivers 3,000 micrograms (mcg) of retinol activity equivalents (RAE)—that’s 333 percent of your daily value (% DV)—sourced from retinyl palmitate, a preformed and highly bioavailable form of vitamin A¹. Since vitamin A is fat-soluble, Nutricost pairs it with sunflower oil to help enhance absorption. Plus, sunflower oil is rich in vitamin E², an antioxidant and natural preservative that helps prevent the oxidation of oils.

That said, a quick heads-up that we’ll continue echoing: while 3,000 micrograms is a common dose in dietary supplements¹, fat-soluble vitamins like A can build up in the body over time and potentially lead to toxicity. For that reason, it’s always a smart idea to take them under the guidance of a healthcare provider.

Safety considerations aside, this formula earns a solid 4 out of 5. The high-quality source of vitamin A and inclusion of oil are definite strengths, but we gave preference to non-seed oils, and there’s no confirmation of the formulation’s purity from reputable third-party organizations like NSF, which slightly lowers its score.

That said, the product claims third-party testing and is made in a GMP-certified, FDA-registered facility, which is great—but the brand doesn’t disclose who does the testing or whether it includes banned substance screening. For athletes or ingredient-conscious consumers, that’s worth keeping in mind. For that, we’re giving transparency a 3 out of 5.

As for swallowability, it deserves its perfect 5 out of 5—the softgel is small, smooth, and easy to take. Taste-wise, it’s virtually neutral, though there is a faint scent when you open the bottle, which slightly brings the overall taste experience down to a 4 out of 5.

Personally, I had no digestive issues or side effects, and some users even report benefits like clearer skin and fewer breakouts. While everyone’s experience will vary, the positive feedback earns a solid 5 out of 5, here.

All things considered, Nutricost’s vitamin A is a strong, budget-friendly option, clocking in at under $0.05 per serving. And with a 60-day return policy, it’s a low-risk pick for first-time buyers.

Why Not Natural 10,000 IU Vitamin A Drops are a solid alternative if you’re looking for more flexible dosing from your supplement.

If you’re looking for a comprehensive daily greens powder that contributes to your vitamin A needs—and then some—AG1 is a reliable way to fill in nutritional gaps. As expert tester Nicole Davis, CPT, PN1-NC, puts it, “It’s an effective habit that I could see being a good safeguard, especially for those with less-than-stellar diets.”

Each scoop provides 250 micrograms of retinol equivalents (RE) from beta-carotene—about 31 percent of your daily value. While that’s more modest compared to multivitamins, which often offer between 83 and 117 percent of your daily value¹, it’s still a meaningful boost—especially if you’re already getting vitamin A from food sources.

And that’s just the start: AG1 packs 74 more ingredients, which we break down in detail in our Athletic Greens Review. 

To clarify, Retinol Equivalents (RE) and Retinol Activity Equivalents (RAE) are two ways of measuring vitamin A. According to a 2023 review³, REs (used by the FAO) assume beta-carotene is more readily absorbed, while RAEs (used by the IOM) are more conservative. For reference, 1 microgram RAE = 12 micrograms of beta-carotene, whereas 1 microgram RE = 6 micrograms.

Technical details aside, AG1 made a strong impression in terms of taste and mixability. Nicole gave it a 4.5 out of 5 for flavor, describing it as, “Mild and (as expected) a bit grassy, but you do get hints of pineapple and vanilla.” There was a little settling at the bottom of the glass, according to Nicole, but no grittiness, earning a 4 out of 5 for solubility.

AG1 earns a perfect 5 out of 5 for third-party testing thanks to its NSF Certified for Sport seal. This certification ensures that it has been rigorously tested for purity and screened for banned substances, which is imperative for athletes subject to drug testing or anyone who wants peace of mind.

At $99 for 30 servings, value is where AG1 takes a hit, receiving just 1 out of 5 in this category. But for those prioritizing convenience, quality, and comprehensive support, it may be worth the investment.

If you’re not looking for an all-in-one formula and enjoy flavorful supplements, Bulletproof Vitamin A+D+K Gummies could be a great fit for you.

Vitamin A plays a crucial role in maintaining healthy vision, so getting enough of it is essential for supporting long-term eye health. While a balanced diet is always the foundation, a well-formulated supplement can fill in nutritional gaps—and NOW Foods Vitamin A 10,000 IU Softgels stand out for several great reasons.

To start, they’ve earned an impressive 4.7 out of 5 stars from over 3,000 reviews on Amazon. One user even noted their eye doctor recommended the brand, while others reported noticeable improvements in eye health, including better night vision.

Each softgel delivers 3,000 micrograms (RAE) of preformed vitamin A—a highly bioavailable form—from retinyl palmitate and fish liver oil. It also contains organic extra virgin olive oil to enhance absorption of the fat-soluble vitamin. While the formula is solid overall, it would benefit from the addition of an antioxidant, such as vitamin E, to help preserve the freshness of the oil. For that, it earns a 4 out of 5 for the category.

The softgels themselves are tiny, easy to swallow, and leave no unpleasant aftertaste. They earn a 5 out of 5 for swallowability and a 4 out of 5 for taste, with only a minor deduction for a faint scent when first opening the bottle.

The largest area for improvement is third-party testing and transparency. While this supplement is manufactured in a GMP-certified facility—and NOW Foods has a strong reputation for quality—it doesn’t currently carry third-party certifications like Informed Sport or NSF. For ingredient-conscious shoppers or athletes who value that extra layer of assurance, this could be a drawback. As a result, it earns a 3 out of 5 for transparency and testing.

Still, at just $0.08 per serving, this supplement scores for value with a perfect 5 out of 5 rating in this category. With 100 softgels per bottle, it provides more than three months of consistent support for your eyes and overall health.

If you’re seeking a vitamin A supplement with antioxidant-rich tocopherols to help preserve the oil, consider Swanson Vitamin A 10,000 IU Softgels.

If you’re looking for a vegan-friendly way to boost your vitamin A intake, consider Why Not Natural 10,000 IU Vitamin A Drops. While vitamin A is often tied to carrots and sweet potatoes, the bioavailable forms are typically animal-derived, making this plant-based liquid a solid option for those on plant-forward diets.

Each 9-drop serving delivers 3,000 micrograms of vitamin A as palmitate—a readily absorbed form—blended with MCT oil, natural orange extract, and mixed tocopherols (the major forms of vitamin E²) to support absorption and preserve potency. 

Still, there are transparency issues to consider. While the product is labeled vegan, it doesn’t clarify the source of its palmitate, a form often derived from animal products. Combined with limited transparency in third-party testing (the company mentions GMP compliance and purity testing, but not the specific lab used), it scores 3.5 out of 5 for formulation and 3 out of 5 for third-party testing.

That said, the citrus-flavored liquid earns top marks for taste and ease of use. It earned a 5 out of 5 for both swallowability and flavor, highlighted by how seamlessly and effortlessly it could fit into a supplement routine. 

Customer reviews are also overwhelmingly positive, averaging 4.7 out of 5 across more than 1,000 ratings. Many users report improved skin clarity and even better vision. As one reviewer put it, “My eyesight improved after just a few weeks.”

While the price per serving is slightly above average, earning a 3 out of 5, Why Not Natural is a compelling option for anyone seeking an easy-to-take, plant-based vitamin A supplement.

AG1 might be a more appealing option if you value third-party testing certifications and vegan products—and have flexibility in your budget to accommodate the higher cost.

Vitamin A capsules are usually small and easy to swallow, but their smell isn’t always the most pleasant. Additionally, not everyone enjoys taking capsules or prefers a fixed dose. That’s where Pure TheraPro Rx Vegan A-D-K Drops come in—a flexible, liquid form that gives you more than just vitamin A.

A 5-drop dose delivers 1,500 micrograms RAE of vitamin A (in the highly absorbable palmitate form), along with 125 micrograms of vitamin D3⁴ (similar to some of the best vitamin D supplements), and 600 micrograms of vitamin K2⁵. Together, these support your vision, immune function, cardiovascular and bone health, and overall wellness.

To help your body better absorb these fat-soluble vitamins, the drops include organic MCT oil sourced from coconuts. While including an antioxidant would improve the formulation rating, it still scores a solid 4 out of 5. 

Because it’s a liquid and you only need 5 drops per serving, it gets a perfect 5 out of 5 for swallowability. Most people find the taste mild and pretty easygoing, though a few notice a slightly salty or off flavor. Based on my experience and customer feedback, it receives a 4 out of 5 for taste.

Amazon customers also give it an impressive 4.5 stars out of 5, based on over 860 reviews, with many users reporting increased energy, improved vitamin D levels, and quick absorption. 

In terms of testing and transparency, it’s made in a GMP-certified facility and offers third-party testing, although it doesn’t carry certification from a major independent group like NSF. However, it does provide a Certificate of Analysis (COA), earning it a 3.5 out of 5 for third-party testing.

The price is a bit higher than many softgel options—about $0.44 per serving—giving it a 2 out of 5 for cost. But since you’re also getting vitamins D and K alongside A, it might be worth the extra investment for some users. 

You may consider Bulletproof Vitamin A+D+K Gummies if you want adequate doses of vitamins A, D, and K in a gummy format.

Swanson Vitamin A 10,000 IU Softgels currently retail for just $0.04 per serving on Amazon—and even less with a subscription—making it an excellent value for any budget. Thanks to its affordability, it earns a perfect 5 out of 5 rating for price. But low cost doesn’t mean low quality—this supplement has more going for it than just the price tag.

Each softgel delivers 3,000 micrograms RAE, sourced from both cod liver oil and vitamin A palmitate with high bioavailability. It also includes an intentional synergistic combo: flaxseed oil to support absorption and tocopherols to help preserve the oil. #TeamWork

The formulation is solid, but third-party testing is where things get a little murky. Swanson claims the brand’s supplements are tested by independent labs and follow GMP standards. However, there’s no third-party certification from reputable organizations listed on this specific product’s label. 

While Swanson seems to be a reputable brand, this lack of clarity knocks its third-party testing score to a 3 out of 5. Its formulation also lands at a 4 out of 5 rating, which could easily improve with verified testing credentials.

On the usability front, these softgels are a win. They’re small, easy to swallow, and unflavored, earning a 5 out of 5 for swallowability. However, like many other vitamin A supplements, they have a noticeable smell, which slightly reduces the taste rating to 4 out of 5.

Customer feedback lines up with these scores: the product boasts a 4.6-out-of-5-star rating from over 450 reviews on Amazon. Users consistently praise its quality, value, and easy-to-swallow size—plus, there are no fishy burps, a common complaint with some of the best fish liver oil supplements.

If you value third-party testing and transparency, Carlson Cod Liver Oil offers a natural source of vitamin A with clear certifications for purity and safety. 

Not into swallowing capsules or dealing with liquid drops? Bulletproof’s Vitamin A+D+K Gummies offer a tasty, easy-to-take alternative that packs three essential fat-soluble vitamins in fruity bites. Think of them as a vitamin-rich candy option similar to some of the best creatine gummies on the market today.

Each serving delivers 900 micrograms of vitamin A (from highly bioavailable retinyl palmitate), plus 50 micrograms of vitamin D3 to support your immune system, bone health, and muscle function. It also provides two forms of vitamin K—1,000 micrograms of K1 for blood clotting and 180 micrograms of K2, which helps regulate calcium and supports strong bones⁵.

Some things to keep in mind: these gummies don’t contain added fats, which helps the body absorb fat-soluble vitamins. That’s not unusual for gummies, but it does mean you’ll want to take them with a meal to get the most benefit. They also don’t contain added sugar but use sugar alcohols, which may cause some digestive distress in some, resulting in an overall 3.5 out of 5 formulation rating.

Bulletproof gets points for transparent labeling and notes quality assurance testing. However, there’s no indication of third-party certifications from reputable groups like NSF, which brings the third-party testing score to a 2 out of 5.

Flavor-wise, our expert product tester Amanda Capritto, CPT, CES, CNC, CF-L1, CSNC raves that they’re, “SO GOOD,”—yes, in all caps—and gives their taste a perfect 5 out of 5. Most users agree, though a few mention a slight artificial aftertaste. Texture-wise, reviews are mixed. Some find the gummies soft and a little sticky, which affects their overall ease of consumption and brings the swallowability score to a 3 out of 5.

Regarding cost, they’re on the higher end at $0.83 per serving, which earns just a 1 out of 5 in this category. Still, the convenience and benefit of getting multiple vitamins in a flavorful gummy may justify the cost.

Pure TheraPro Rx Vegan A-D-K Drops may be a better option if you’re looking for the benefits of vitamins A, D, and K without the sugar alcohols or potential texture issues.

I’ll be honest—I didn’t imagine myself staring down a large (and very green) bottle of cod liver oil in the name of testing vitamin A supplements. But here we are, and Carlson absolutely won this stare-down with its pure formulation, third-party certifications, and surprisingly non-fishy flavor.

Carlson’s nutritionals are quite the catch—each serving provides 255 micrograms RAE of vitamin A (28% Daily Value) sourced from cod liver oil and retinyl palmitate, along with 10 micrograms (400 IU) of vitamin D3 and 6.7 mg of vitamin E. That’s on top of a generous 1,100 milligrams of total omega-3 fatty acids—500 milligrams DHA, 370 milligrams EPA, and 50 milligrams DPA—from 100% Norwegian cod liver oil.

To preserve freshness and prevent oxidation, the oil is bottled using a nitrogen flush and a touch of antioxidants. It’s also certified by both the International Fish Oil Standards (IFOS) and IGEN (Non-GMO Verified), earning a perfect 5 out of 5 for third-party testing.

Now to be really honest, this was the last product I tried. The word “cod” alone made me wrinkle my nose. Add “liver” to the mix, and my mouth basically sealed itself shut. But hey, product testing is serious business around here, so I braced myself—and truly to my surprise, it deserves its perfect 5 out of 5 for taste. 

And I’m not the only one impressed. With over 9,200 reviews and a stellar 4.8-star average on Amazon, Carlson clearly has a fan base. Many customers love the light lemon aftertaste and note there’s no fishy flavor or dreaded burps. Some even report benefits, such as reduced post-workout soreness and improved joint comfort.

Yes, the price per serving comes in at $0.47—earning a 2 out of 5 for cost—but what you get in return is a high-quality, easy-to-take supplement packed with essential nutrients.

If the idea of tossing back cod liver oil doesn’t appeal to you, Carlson Vitamin A softgels might be a better fit.
