Natural remedies for vitamin A deficiency

IMPORTANT: Vitamin A deficiency can seriously affect vision (up to irreversible blindness in severe cases), immunity and skin health, and it is a common problem in young children, pregnant women and people with chronic intestinal diseases. On the other end, excess vitamin A (especially from supplements or large amounts of liver) is toxic, causes headaches, damages the liver and can produce fetal malformations. Do not take retinol supplements during pregnancy without medical advice. Consult your doctor before starting any supplementation, especially if you have liver disease, Crohn’s disease, cystic fibrosis or have been diagnosed with hypervitaminosis.

“Eat the carrot, child, so you can see well at night.” My grandmother always placed a raw carrot at the bottom of the soup bowl for us to eat at the end, with black bread and a sprinkle of salt. “The carrot and the chicken liver, those two keep a person’s eyes clear until old age,” she used to say, and she was right in a way she herself did not fully know. Vitamin A, that miraculous substance that makes our retina work properly in the dark, was hiding in those very simple foods that grandmother placed before us without much fanfare.

Vitamin A deficiency is, sadly, more common than most people think. In developed countries severe forms are rare, but subclinical deficiencies, those that do not yet produce dramatic signs, affect a significant number of people: children with a diet low in vegetables, adults on overly restrictive diets, people with intestinal malabsorption, smokers and pregnant women without access to diverse food. Symptoms set in slowly: eyes get dry in the evening, skin becomes rough, wounds heal with difficulty, colds multiply.

The good news is that vitamin A is abundant in traditional food. From the garden carrot to poultry liver, from the yolk of country eggs to the rich summer butter, we have at hand everything we need. In this article we will walk through all natural remedies together, learn how to combine them properly and discover the old wisdom that, once again, matches perfectly with modern science.

Why vitamin A is important

Vitamin A is a fat-soluble vitamin, which means it dissolves in fats and is stored in the liver for long periods. It exists in two main forms: retinol (preformed vitamin A, found in foods of animal origin) and carotenoids, especially beta-carotene (provitamin A, found in colorful vegetables and fruits, which the body converts into retinol as needed).

Its roles are many and essential. First, vitamin A is decisive for vision, especially in low-light conditions. Rhodopsin, the retinal pigment responsible for dark perception, cannot regenerate without retinol. Second, vitamin A maintains the integrity of skin and mucous membranes (eyes, nose, mouth, lungs, digestive tract, urinary tract), being thus a first line of defense against infections. Third, it regulates the immune system, cell division, growth, reproduction and proper bone formation.

In children, severe deficiency causes xerophthalmia (dry eye), keratomalacia (corneal ulceration) and blindness. In adults, symptoms are more subtle but affect long-term quality of life. The World Health Organization considers vitamin A deficiency one of the most serious nutritional issues globally, alongside iron, iodine and zinc deficiencies.

Symptoms of deficiency

Signs appear gradually, and the first ones are often overlooked:

• Night blindness (nyctalopia): difficulty adapting to darkness after leaving a lit area
• Dry eyes, gritty sensation, reduced tears
• Dry, rough, scaly skin, especially on arms and thighs (follicular keratosis, known as “chicken skin”)
• Dry, brittle hair, breaking nails
• Frequent respiratory infections, colds that “never end”
• Slow wound healing, skin infections
• Dental problems in children (thin enamel)
• Growth delay in young children
• Infertility and reproductive problems
• White spots on the conjunctiva (Bitot’s spots), a late sign

If several of these symptoms occur together, especially night blindness and rough skin, discuss with your doctor and request a serum retinol blood test.

Remedy 1: Carrots with fat

The carrot is the king of carotenoids. A hundred grams of carrot contain approximately 835 micrograms of retinol equivalent (RE), slightly above the daily requirement of an adult. But be careful: beta-carotene is fat-soluble, which means it is absorbed only when consumed together with fat.

How to prepare properly

• Finely grated with oil: grate a big carrot, add a teaspoon of cold-pressed olive oil, a little salt, a squeeze of lemon. Mix well and let the oil infuse for five minutes.
• Boiled with butter: carrots lightly boiled in salted water, then tossed in fresh butter, release twice as much beta-carotene as plain raw carrots.
• Carrot cream soup: boiled with a bit of onion, potato and a teaspoon of butter or rich cream, forms one of the most bioavailable forms of vitamin A.

Grandmother cut them into rounds and lightly sauteed them in lard, together with an onion and a pinch of caramelized sugar. “The lard draws the yellow out of the carrot,” she said. She was perfectly right: animal fat increases the bioavailability of carotenoids by up to 600% compared with raw consumption.

Recommended daily intake

One medium carrot per day, consumed with fat, covers the daily requirement. For children, half a carrot per day is sufficient. Do not overdo it: excessive carrot consumption can produce carotenemia, a yellow-orange pigmentation of palms and soles, harmless but unsightly.

Remedy 2: Chicken, beef or pork liver

Liver is the richest natural food in vitamin A as active retinol. A hundred grams of beef liver contain approximately 9000 micrograms of retinol, that is ten times the daily requirement. Exactly for this reason it must be consumed in moderation.

How to prepare

• Chicken liver with onion: a simple, tasty recipe. Fry the onion in lard, add diced chicken liver, brown for 5-7 minutes, salt, pepper, add a bay leaf. Serve with warm polenta.
• Homemade liver pate: liver boiled with onion and carrot, mashed with fresh butter, cinnamon and a drop of brandy. Eaten with black bread.
• Grilled liver: thinly sliced, soaked in milk for 30 minutes to remove bitterness, then on the grill 2 minutes per side.

How often

A portion of 80-100 grams, once a week, is enough to maintain vitamin A stores. Not more often, because excess accumulates and can be toxic. Pregnant women should avoid liver due to the very high retinol content, which can harm the fetus.

Remedy 3: Fish oil and cod liver oil

Fish oil, especially cod liver oil (“Lebertran” as it was called in Central Europe), was for generations the main source of vitamins A and D for European children. A teaspoon of cod liver oil contains 4500 IU of vitamin A and 450 IU of vitamin D, a true “pharmacy” in a single dose.

How to consume it

• Liquid oil: one teaspoon in the morning, right after breakfast, with a slice of lemon. The taste is not pleasant, but the effect is worth it.
• Capsules: modern alternative, practically tasteless. 1000-2000 IU of vitamin A per day, according to package directions.
• Fatty fish: salmon, mackerel, herring, sardines, anchovies. A 150-gram portion 2-3 times a week.

Mind the quality

Choose fish oils from reputable brands, tested for heavy metals (mercury, lead, cadmium) and freshness (not rancid). Rancid oil produces free radicals, exactly the opposite of what you want.

Remedy 4: Egg yolk and full-fat dairy

A country egg yolk contains approximately 80 micrograms of retinol, plus lutein and zeaxanthin, carotenoids that protect the retina. Full-fat dairy products (butter, cream, whole milk, rich cheeses) are also good sources of retinol, provided they are “real”, meaning with all the fat.

How to include them daily

• Two eggs in the morning, soft-boiled, sunny side up or scrambled with butter. The yolk should remain runny to preserve nutrients.
• Raw butter on bread: 15-20 grams of quality butter, spread on dark rye bread with a slice of aged cheese. A classic snack.
• Cream on soups: a tablespoon of rich cream (30% fat) added at the end to vegetable soups or fish dishes.

Grandmother’s tip

“The hen’s egg keeps the eye alive and the hair thick.” Grandmother gave us every morning a soft-boiled egg with salt and bread, and on Saturdays a large omelet with cheese and green onion. It was a simple meal, but extremely nutrient-dense.

Remedy 5: Orange and dark green vegetables

Besides carrot, there are several vegetables rich in beta-carotene, all with the same rule: eat them with fat for good absorption.

Complete list

• Baking pumpkin: 100 g provides 800 µg RE. Baked with honey and cinnamon it is a healthy dessert.
• Sweet potato: 100 g = 960 µg RE. Baked in its skin, with butter and a sprinkle of salt.
• Spinach: 100 g = 470 µg RE. Boiled with a bit of garlic and cream, an excellent side.
• Kale: 100 g = 500 µg RE. Raw in salad with oil or steamed.
• Broccoli: 100 g = 80 µg RE. Steamed for 4 minutes preserves most of the beta-carotene.
• Red bell pepper: raw in salad, or roasted with olive oil.

The color principle

“The more colorful the plate, the healthier it is,” the old folks used to say. A simple rule, but surprisingly accurate biochemically. The colors yellow, orange, red, dark green indicate the presence of carotenoids.

Remedy 6: Yellow and orange fruits

Fruits are an accessible, pleasant and easy-to-integrate source.

• Apricots: fresh or dried (100 g dried apricots = 360 µg RE). A perfect between-meals snack.
• Peaches and nectarines: abundant in summer. With full-fat yogurt, they cover a day’s needs.
• Mango: an exotic but accessible fruit, 100 g contains 160 µg RE.
• Papaya: 100 g = 280 µg RE, plus digestive enzymes that aid absorption.
• Cantaloupe melon: hydrating and sweet, 100 g = 170 µg RE.

How to combine them

• Fruit salad with full-fat yogurt and a few nuts
• Smoothie with mango, apricots, carrot, orange and a teaspoon of flaxseed oil
• Dried apricots chopped into muesli, with sunflower seeds

Remedy 7: Vitamin A supplements

Supplements are useful in well-documented cases of severe deficiency, in strict vegans who do not consume animal products, in people with malabsorption (Crohn’s disease, ulcerative colitis, celiac disease) or in those who cannot reach requirements through diet.

Available types

• Retinol palmitate or retinyl acetate: active form, low dose (2500-5000 IU per day)
• Beta-carotene: safer form, the body converts it to retinol only if needed
• Cod liver oil: natural source, contains A + D + omega 3

Important precautions

Large doses (over 10,000 IU of retinol per day, for adults) can be toxic long-term. Signs of toxicity include: headaches, nausea, dry skin, hair loss, bone pain. Pregnant women should NOT take retinol supplements without medical indication. Smokers should avoid high-dose beta-carotene supplements, which have been associated with increased risk of lung cancer.

Practical tips for optimal absorption

• Eat colorful vegetables with fat (olive oil, butter, lard, avocado). Without fat, absorption drops by over 50%.
• Cook vegetables gently: short boiling or steaming releases carotenoids from cell walls, increasing bioavailability.
• Combine with zinc: zinc (from meat, shellfish, nuts) is needed for the conversion of beta-carotene to retinol.
• Avoid extreme fat-free diets: they dramatically reduce absorption of fat-soluble vitamins.
• Do not abuse alcohol: alcohol depletes hepatic vitamin A reserves.
• Smokers: prefer food sources, not beta-carotene supplements.
• People with biliary problems: absorption is much reduced, discuss supplementation with your doctor.
• Do not exceed one portion of liver per week regularly.

Conclusion

Vitamin A deficiency is best prevented and corrected through food. Carrots with lard, country chicken liver, fresh egg yolk, baked pumpkin and summer apricots, tasty butter and cream, all form a natural pharmacy that our ancestors used instinctively, without knowing scientific names.

Vitamin A is a treasure for vision, skin and immunity. With a few simple changes to the daily menu, with the old wisdom of seasonal dishes and with attention to the good fats that allow it to be absorbed, you can prevent the onset of deficiency and enjoy its benefits for a long time. But do not forget that any suspicion of severe deficiency calls for blood tests and medical advice. Natural remedies are wonderful, but they do not replace professional diagnosis.

Frequently asked questions

1. Can I get all the vitamin A I need only from vegetables and fruits?

Yes, if you have a healthy digestive system and eat colorful vegetables with fat every day. However, the conversion of beta-carotene to retinol varies a lot from person to person (some convert less efficiently for genetic reasons). That is why, if possible, include eggs, butter or liver occasionally, to have preformed retinol as well.

2. My carrots turned my child’s palms yellow. Is it dangerous?

No, it is carotenemia, a harmless pigmentation that appears when one eats many orange vegetables. Palms, soles and sometimes the face take on a yellow-orange hue. The whites of the eyes remain unaffected (unlike jaundice, where the sclera also turns yellow). By reducing carrots for a few weeks, the color disappears on its own.

3. I heard beta-carotene is dangerous for smokers. Is it true?

A major study called CARET showed that smokers who took large doses of beta-carotene as supplements had an increased risk of lung cancer. This refers to supplements, not to eating carrots, pumpkins or sweet potatoes. Smokers should avoid beta-carotene supplements and get carotenoids exclusively from food.

4. I am pregnant. Can I eat carrots and sweet potatoes without worry?

Yes, absolutely. Beta-carotene from vegetables is not toxic during pregnancy, because the body converts it to retinol only as needed. What you must avoid is liver (very rich in preformed retinol) and high-dose retinol supplements, which can cause fetal malformations. Ask your doctor for specific recommendations on prenatal vitamins.

5. How long does it take to restore vitamin A levels after a deficiency?

With proper nutrition, with varied sources of retinol and carotenoids, serum levels normalize in 4-8 weeks. Hepatic reserves rebuild more slowly, in 3-6 months. In severe deficiencies with ocular involvement, the doctor may prescribe rapid loading doses for 1-3 days, followed by maintenance. Recovery of night vision is rapid (days to weeks), but advanced corneal lesions can be permanent.
