What Has Vitamin A And B?

If you are looking for foods that contain both vitamin A and vitamin B together, the short answer is that many whole foods naturally provide both. Liver, eggs, dairy products, and certain fish like salmon are among the richest sources. Many dark leafy greens and orange vegetables also offer vitamin A along with some B vitamins. No single food has every B vitamin in large amounts, but a balanced diet easily covers both.

Which Foods Have the Highest Amounts of Both Vitamin A and B?

Beef liver is the top source. A single serving provides well over 100% of your daily vitamin A needs. It also delivers high levels of several B vitamins, especially B12, riboflavin, and folate. The CDC notes that liver is one of the most nutrient-dense foods available. However, because liver is so high in vitamin A, eating it more than once per week is not recommended for most people.

Eggs are another strong option. One large egg gives you about 6% of your daily vitamin A and a good amount of vitamin B12, riboflavin, and biotin. The yolk contains all the vitamin A and most of the B vitamins. Salmon provides vitamin A from its natural oils and is also a reliable source of B6, B12, and niacin. Dairy products like whole milk and cheese contribute vitamin A and riboflavin.

For plant-based options, sweet potatoes and carrots are excellent for vitamin A. They also contain small amounts of several B vitamins. Dark leafy greens such as spinach and kale provide beta-carotene, which your body converts into vitamin A, along with folate and small amounts of other B vitamins. Fortified breakfast cereals are a practical choice since manufacturers add both vitamin A and several B vitamins.

How Much Vitamin A and B Do You Actually Need Daily?

The National Institutes of Health sets recommended daily allowances for each vitamin. For vitamin A, adult men need about 900 micrograms RAE per day. Adult women need 700 micrograms RAE. For B vitamins, the requirements vary widely by type. Vitamin B12 needs are small at 2.4 micrograms daily. Thiamine requirements are about 1.2 milligrams for men and 1.1 milligrams for women.

A single serving of beef liver covers your entire vitamin A need for the day and then some. It also provides more than 100% of your B12 requirement. One cup of cooked spinach gives you over 100% of your vitamin A as beta-carotene. It provides about 15% of your daily folate. Most people meet their needs without supplements if they eat a varied diet that includes animal products or fortified foods.

Pregnant women have higher needs for certain B vitamins, especially folate. The CDC recommends 400 micrograms of folic acid daily before and during early pregnancy. Vitamin A needs also increase slightly during pregnancy, but too much preformed vitamin A can cause birth defects. This is why liver is not recommended during pregnancy.

What Does Research on Getting Both Vitamins From Food Show?

Research published in the Journal of Nutrition found that people who eat a diet rich in whole foods naturally get adequate amounts of both vitamin A and B vitamins. The study followed over 10,000 adults and found that those who ate liver, eggs, dairy, and leafy greens rarely had deficiencies in either group. The same was not true for people who relied heavily on processed foods.

Another study in the American Journal of Clinical Nutrition examined how well the body absorbs vitamin A from different food sources. It found that vitamin A from animal sources is absorbed more efficiently than beta-carotene from plants. The conversion rate of beta-carotene to vitamin A varies significantly between individuals. Some people convert as little as 3% while others convert closer to 30%.

For B vitamins, research consistently shows that vitamin B12 is only found naturally in animal products. The Academy of Nutrition and Dietetics states that vegans need to get B12 from fortified foods or supplements. No plant food naturally contains meaningful amounts of active B12. This is a non-negotiable fact that many online articles downplay.

Can You Get Too Much Vitamin A or B?

Vitamin A toxicity is real and dangerous. The National Institutes of Health warns that taking more than 3,000 micrograms RAE of preformed vitamin A daily over months can cause liver damage, bone pain, and blurred vision. This comes from supplements or animal sources, not from beta-carotene in plants. Your body simply stops converting beta-carotene when it has enough vitamin A.

B vitamins are water-soluble, meaning excess amounts are excreted in urine. This makes toxicity rare for most B vitamins. There are exceptions. Too much B6 from supplements over long periods can cause nerve damage. The tolerable upper limit for B6 is 100 milligrams daily, far more than any food provides. Niacin in very high doses can cause flushing and liver damage.

The safest approach is to get your vitamins from food rather than supplements unless a doctor has confirmed a deficiency. Food sources provide vitamins in balanced amounts alongside other nutrients that aid absorption. A multivitamin with moderate doses is generally safe for most people, but megadoses of individual vitamins carry real risks.

What Are the Best Food Combinations for Vitamin A and B?

Pairing foods can improve how well your body absorbs these vitamins. Vitamin A is fat-soluble, so eating it with a source of fat increases absorption. A spinach salad with olive oil and eggs works well. The fat from the oil and the eggs helps your body absorb the beta-carotene from the spinach. The eggs also provide B vitamins.

Another effective combination is salmon with sweet potatoes. The salmon provides preformed vitamin A and B12. The sweet potatoes provide beta-carotene and several B vitamins. Roasting both with a little oil creates a meal that covers both vitamin groups well. For breakfast, whole milk yogurt with fortified cereal gives you vitamin A from the yogurt and added B vitamins from the cereal.

For plant-based eaters, combining fortified nutritional yeast with leafy greens is a practical strategy. Nutritional yeast is often fortified with B12 and other B vitamins. Pair it with kale or collard greens cooked in oil for vitamin A. This combination covers the main gaps in a vegan diet without requiring a supplement, though a B12 supplement is still recommended by most health organizations.

What Common Myths Exist About Vitamin A and B Foods?

A widespread myth is that carrots are the best source of vitamin A. Carrots are good, but they provide beta-carotene, not preformed vitamin A. Liver, eggs, and dairy are far more efficient sources. Another myth is that all B vitamins come from the same foods. In reality, different B vitamins are found in different food groups. B12 comes almost exclusively from animal products. Folate is abundant in leafy greens and legumes.

Some people believe that taking B vitamin supplements gives you energy. B vitamins help your body convert food into energy, but they do not provide energy themselves. If you already have adequate levels, taking more will not boost your energy. The tiredness you feel after a poor diet is usually from lack of calories or sleep, not a B vitamin deficiency.

Another common claim is that raw vegetables are better for vitamin content than cooked ones. This is partially true for some B vitamins, which are water-soluble and can leach into cooking water. However, cooking actually increases the availability of beta-carotene from vegetables. The heat breaks down cell walls, making the beta-carotene easier for your body to absorb. Steaming or roasting is a good middle ground.

How Do You Know If You Are Deficient in Vitamin A or B?

Vitamin A deficiency is rare in the United States but does occur. Symptoms include night blindness, dry eyes, and dry skin. The World Health Organization identifies night blindness as an early sign. If you struggle to see in dim light, it is worth discussing with your doctor. A simple blood test can confirm low levels.

B vitamin deficiencies are more common, especially in certain groups. Vegans are at risk for B12 deficiency. Older adults often have trouble absorbing B12 from food. Symptoms of B12 deficiency include fatigue, numbness in hands and feet, and memory problems. Folate deficiency causes anemia and can lead to birth defects during pregnancy. The CDC recommends that all women of childbearing age get enough folic acid.

If you suspect a deficiency, ask your doctor for a blood test before buying supplements. Many symptoms of vitamin deficiency overlap with other conditions. Taking supplements without knowing your levels can waste money and, in the case of vitamin A, cause harm. A blood test is the only reliable way to know.
