If you’ve ever stared at a nutrition label in the grocery store and wondered why vitamin A is consistently highlighted as a “key nutrient,” you’re not alone. When I started out in the vitamins business a decade ago, I’ll admit I thought vitamin A was just another fancy buzzword—until I saw how a lack of it impacted customers I’d worked with, both through our product lines and the community outreach we do each year. Vitamins
I once had a customer, a elementary school teacher in Ohio, tell me half her third-grade class was coming down with colds more often that year. She’d swapped their afternoon sugary snacks for fruit cups, but she noticed they were still dragging their feet through math and reading. It turned out many of their families didn’t eat a lot of leafy greens or orange vegetables, and she’d never realized a simple nutrient gap could be causing that kind of fatigue and frequent illness. That conversation stuck with me. It’s why our company’s approach to vitamins isn’t just about selling pills—it’s about educating people on how to get nutrients through food first, then supplement smartly when needed. Vitamin A is one of those nutrients that works best when it’s paired with other compounds from whole foods, so today I want to break down exactly what vitamin A does, which foods deliver the most of it, and how we can help if supplementing makes sense for your diet.
First, let’s get clear on what vitamin A actually is, because there’s a lot of confusion here. It’s not a single compound—it’s a group of fat-soluble nutrients that have two main forms: preformed vitamin A (retinoids) and provitamin A carotenoids. Preformed vitamin A is the kind your body can use right away, and it’s found only in animal products. The other form, provitamin A, is what plants make—think of it as a precursor your body converts into active vitamin A. The most common of these carotenoids is beta-carotene, which is what gives orange and yellow fruits and vegetables their bright color (and sometimes leafy greens, like spinach, have a lot too—they’re just covered in chlorophyll that masks the orange hue).
Why does vitamin A matter so much? It’s a workhorse for your body. It supports eye health—think of it helping your eyes adjust from bright light to dark rooms, which is why old cartoons used to say carrots help you see in the dark. It also plays a huge role in immune function: it helps your body make white blood cells that fight off infections, keeps the lining of your lungs and intestines intact so germs can’t get in, and even supports cell growth and development, which is especially important for kids and pregnant people. That teacher I mentioned? Her students were low in both immune support and energy, two areas vitamin A directly impacts.
Now, let’s talk about the foods richest in vitamin A, starting with preformed vitamin A, since that’s the most concentrated source. If you eat dairy products, you’ve probably had a food that’s high in this. Beef liver is the absolute leader—wait, let’s get specific: a 3-ounce serving of cooked beef liver has over 15,000 micrograms of retinol activity equivalents (RAE), which is the standard measure for vitamin A. The daily recommended amount for adults is 700 micrograms for women and 900 micrograms for men, so that one serving is 21 times the daily need. But I always tell people not to eat liver every day—too much preformed vitamin A can be a problem, especially for pregnant people, because it can impact fetal development. That’s part of why whole food sources should be the foundation, not the only source.
Other animal-based preformed vitamin A sources include full-fat dairy products. A cup of whole milk has around 140 micrograms RAE, and a half-cup of soft, raw cheddar has about 284 micrograms RAE. Eggs, especially the yolks, are another great one: one large egg has around 75 micrograms RAE, and pairing it with a little fat (like butter or avocado) helps your body absorb that vitamin A better, since it’s fat-soluble. I always recommend adding a little healthy fat when eating vitamin A-rich foods, regardless of their source—this is a common mistake people make, eating these foods with fat-free sides and not getting the full benefit.
Now, for the plant-based folks, this is where provitamin A carotenoids shine. The big star here is sweet potatoes—specifically baked sweet potato with the skin on. One medium baked sweet potato has over 1,400 micrograms RAE, which is almost double the daily adult need. That’s way more than a regular white potato, by the way, because of the beta-carotene. Carrots are the classic example, and a half-cup of raw carrot slices has around 459 micrograms RAE. But you don’t have to stick to orange veggies: dark leafy greens like spinach, kale, and collards are packed with provitamin A. One cup of cooked spinach has about 943 micrograms RAE, which is more than the daily need for most women. Broccoli is another good one—one cup of cooked broccoli has around 108 micrograms RAE, plus fiber and other vitamins that work with vitamin A.
Fruits are also a great source. Mangoes: one whole mango has around 181 micrograms RAE. Cantaloupe: a one-cup serving has over 135 micrograms RAE. Even apricots—three raw apricots have about 70 micrograms RAE, and dried apricots have more concentrated, just watch the added sugar in some packaged versions. I like to add these to smoothies or oatmeal for a quick boost.
Now, the tricky part with provitamin A is that your body only converts a portion of it into active vitamin A. Beta-carotene conversion is about 12:1, meaning you need 12 micrograms of beta-carotene to make 1 microgram of RAE. For other carotenoids, like alpha-carotene, it’s a bit lower, around 24:1. That’s why whole sources are still better than just taking beta-carotene supplements alone, though I should note that some research shows beta-carotene supplements might not have the same benefits as getting it from food, especially for people who smoke. That’s another reason we emphasize food first with our customers, and only recommend supplements when their diet is falling short, under the guidance of a healthcare provider.
I know a lot of people are busy these days, so getting enough vitamin A through food isn’t always easy. Maybe you’re traveling a lot, or you live in an area where fresh produce is hard to get, or you have dietary restrictions—vegan, low-dairy, etc. That’s where supplements come in, and that’s what our company focuses on. We don’t make high-dose liver supplements, because we know that can be risky, especially for certain groups. Our vitamin A supplements are formulated to match the recommended daily amounts, with a mix of preformed retinol (from sustainable sources, by the way—we work with suppliers that use ethical practices for our animal-derived ingredients) and plant-based beta-carotene, so you get the benefits without the risk of overdoing it. We also pair vitamin A with vitamin D and zinc in some of our multivitamins, because those nutrients work together to support immune function and eye health—something I learned early on when researching how nutrients interact, not work in isolation.
Wait, let’s circle back to that teacher I met in Ohio. A few months after our conversation, she reached out to tell me she’d started sending home newsletters for parents, listing simple vitamin A-rich swaps instead of sugary snacks. They added roasted sweet potato fries instead of chips, spinach smoothies instead of soda, and hard-boiled eggs for snack time. She said by the end of the semester, only a handful of kids had missed more than two days of school due to colds, compared to the 18 that had missed over five days the year before. That’s the impact of small, simple changes. It made me realize how much difference education around nutrition makes, and that’s why we don’t just sell vitamins—we create content, hold free workshops for local communities, and partner with nutritionists to make sure people have the right information, not just marketing hype.
I also want to touch on who might be at higher risk for vitamin A deficiency, because it’s more common than some people think, even in places with access to food. People with cystic fibrosis, celiac disease, or other conditions that affect fat absorption often struggle to get enough fat-soluble vitamins like A. Pregnant or breastfeeding people have higher needs, so they might need to adjust their intake, either through food or supplements, under a doctor’s care. Vegans and vegetarians can get enough vitamin A from plant sources, but they need to be mindful of how much they’re eating, since preformed vitamin A is only in animal products. A friend of mine is a vegan mom of two, and she told me she makes a point of eating a large spinach salad with avocado every day, plus a mango for dessert, to make sure she’s getting enough. That works, but if she had a busy week and skipped those, our vegan vitamin A supplement is there as a backup—no animal products, just pure provitamin A and a small amount of plant-based retinol.
One common myth I want to bust here: eating too much of plant-based provitamin A won’t give you toxic levels of vitamin A. Your body only converts as much as it needs, so you might turn orange if you eat a lot of carrots (it’s called carotenemia, and it’s harmless, just temporary), but you won’t have the same toxicity risk as with too much preformed vitamin A. That’s a key point for anyone who loves orange foods—enjoy them, there’s no upper limit on provitamin A from food, which is why it’s the safer long-term choice.
If you’re wondering if you’re getting enough vitamin A, start by tracking your intake for a few days. Write down what you eat, check the nutrition labels, and compare to the RAE numbers I mentioned earlier. If you’re consistently falling short, first try adding one vitamin A-rich food to your daily routine—like a sweet potato for dinner, or a spinach smoothie for breakfast. If that’s still not enough, or if you have a condition that affects absorption, then supplements are a good option. Our team can help you figure out the right supplement for your diet and needs, no pushy sales tactics, just honest advice based on years of working with customers.
OEM & ODM At the end of the day, vitamin A is one of those nutrients that underpins so much of our daily health—from being able to see a movie in the dark to fighting off a cold. It’s not a magic pill, but it’s a foundational part of how our bodies work. We’ve built our business on being honest about nutrition, not overpromising, and making supplements that complement, not replace, whole food diets. If you’re a retailer looking to stock high-quality, science-backed vitamin supplements, or a healthcare provider who wants to partner on nutrition solutions for your patients, we’d love to hear from you. You can reach out to our team to discuss your specific needs, whether you’re looking for bulk orders of our vitamin A supplements, custom formulations, or educational resources to share with your customers.
