Vitamin A is a fat-soluble vitamin that is important for many bodily functions, including good vision, a strong immune system, reproduction, and good skin health.<\/p>\n\n\n\n

There are two types of vitamin A in foods: preformed vitamin A and provitamin A.<\/p>\n\n\n\n

Preformed vitamin A also known as retinol is mostly found in meat, fish, eggs and dairy products.<\/p>\n\n\n\n

On the other hand, the body converts carotenoids found in plant foods (red, green, yellow and orange fruits and vegetables) into vitamin A.<\/p>\n\n\n\n

Pregnant women, breastfeeding mothers, infants and children are at greatest risk of deficiency. Cystic fibrosis and chronic diarrhea can also increase the risk of deficiency.<\/p>\n\n\n\n

Here are 8 signs and symptoms of vitamin A deficiency.<\/p>\n\n\n\n

Dry skin<\/strong><\/h2>\n\n\n\n

Vitamin A is important for the creation and repair of skin cells. It also helps fight inflammation due to certain skin problems.<\/p>\n\n\n\n

Eczema and other skin problems can be caused by not getting enough vitamin A from your daily diet.<\/p>\n\n\n\n

Eczema is a condition that causes dry, itchy and inflamed skin. Alitretinoin, a prescription drug with vitamin A activity, has been shown to be effective in treating eczema in several clinical trials.<\/p>\n\n\n\n

In one 12-week study in people with chronic eczema who took 10 to 40 mg of alitretinoin per day, up to 53% saw a reduction in symptoms.1<\/a><\/sup><\/p>\n\n\n\n

Remember that dry skin can have many causes, but chronic vitamin A deficiency can be one. <\/p>\n\n\n\n

Vitamin A plays an important role in skin regeneration and helps fight inflammation. A deficiency of this nutrient can lead to inflammatory skin conditions.<\/p><\/blockquote>\n\n\n\n

Dry eyes<\/strong><\/h2>\n\n\n\n

Eye problems are one of the most common problems associated with vitamin A deficiency.<\/p>\n\n\n\n

In extreme cases, not getting enough vitamin A can lead to complete blindness.<\/p>\n\n\n\n

Dry eyes or inability to produce tears is one of the first signs of vitamin A deficiency.<\/p>\n\n\n\n

Supplementing your daily diet with vitamin A can improve your well-being.<\/p>\n\n\n\n

One study found that high-dose vitamin A reduced the prevalence of dry eye 63% among infants and children who received supplements for 16 months.2<\/a><\/sup><\/p>\n\n\n\n

\n
Supplements for eyes<\/strong><\/a><\/div>\n<\/div>\n\n\n\n

Vitamin A deficiency can cause dry eyes, blindness or weakening of the cornea. One of the first signs of deficiency is often an inability to produce tears.<\/p><\/blockquote>\n\n\n\n

Infertility, difficulty getting pregnant<\/strong><\/h2>\n\n\n\n

Vitamin A is essential for both male and female reproduction, as well as for the proper development of infants.<\/p>\n\n\n\n

If you are having trouble getting pregnant, vitamin A deficiency may be one of the reasons. Vitamin A deficiency can cause infertility in both men and women.<\/p>\n\n\n\n

Research shows that female rats deficient in vitamin A have difficulty conceiving and may have embryos with birth defects.3<\/a><\/sup><\/p>\n\n\n\n

Other studies suggest that infertile men may have a higher need for antioxidants due to increased oxidative stress in their bodies. Vitamin A is one of the nutrients that act as an antioxidant in the body.<\/p>\n\n\n\n

Vitamin A deficiency is also associated with miscarriages.<\/p>\n\n\n\n

A study that analyzed the blood levels of various nutrients in women who had experienced recurrent miscarriages found that they had low levels of vitamin A.4<\/a><\/sup><\/p>\n\n\n\n

Both men and women who do not get enough vitamin A can have fertility problems. Low levels of vitamin A can also cause miscarriages or birth defects in expectant parents.<\/p><\/blockquote>\n\n\n\n

Slowed growth<\/strong><\/h2>\n\n\n\n

Children who do not get enough vitamin A may experience stunted growth. This is because vitamin A is essential for the proper development of the human body.<\/p>\n\n\n\n

Several studies have shown that vitamin A supplementation alone or with other nutrients can improve growth. Most of these studies were conducted with children in developing countries.5<\/a><\/sup><\/p>\n\n\n\n

In fact, an Indonesian study of more than 1,000 children found that those with vitamin A deficiency who took high-dose supplements for four months grew 0.39 cm more than children who took a placebo.6<\/a><\/p>\n\n\n\n

However, a review of studies found that vitamin A supplementation with other nutrients may have a greater effect on growth than vitamin A supplementation alone.<\/p>\n\n\n\n

Vitamin A deficiency can cause stunted growth in children. Supplementing vitamin A with other nutrients can improve growth more than supplementing with vitamin A alone.<\/p><\/blockquote>\n\n\n\n

Infections<\/strong><\/h2>\n\n\n\n

Frequent infections, especially in the throat or chest, can be a sign of vitamin A deficiency.<\/p>\n\n\n\n

Vitamin A supplements may help with respiratory infections, but research results are mixed.<\/p>\n\n\n\n

A study in children in Ecuador found that underweight children who took 10,000 IU of vitamin A per week had fewer respiratory infections than those who took a placebo.7<\/a><\/p>\n\n\n\n

On the other hand, a review of studies in children found that vitamin A supplements may increase the risk of developing throat and chest infections 8%.<\/p>\n\n\n\n

Additionally, high blood levels of the provitamin A carotenoid beta-carotene may protect against respiratory infections, according to one study in the elderly.<\/p>\n\n\n\n

Vitamin A supplements may protect underweight children against infections, but may increase the risk of infection in other groups. Adults with high blood levels of vitamin A may have fewer throat and chest infections.<\/p><\/blockquote>\n\n\n\n

Poor wound healing<\/strong><\/h2>\n\n\n\n

Wounds that do not heal well after trauma or surgery may be associated with low vitamin A levels.<\/p>\n\n\n\n

This is because vitamin A stimulates the production of collagen, an important component of healthy skin. Research shows that both oral and topical vitamin A can strengthen the skin.<\/p>\n\n\n\n

A study in rats showed that oral vitamin A improved collagen production. <\/p>\n\n\n\n

Additional studies in rats showed that treating the skin with topical vitamin A appeared to protect against wounds associated with diabetes.<\/p>\n\n\n\n

Human studies show similar results. Older men who treated their wounds with topical vitamin A had a 50% reduction in wound size compared to men who did not use the cream.8<\/sup><\/a><\/p>\n\n\n\n

Oral and topical forms of vitamin A can promote wound healing.<\/p><\/blockquote>\n\n\n\n

Acne<\/strong><\/h2>\n\n\n\n

Because vitamin A promotes skin development and fights inflammation, it can help prevent or treat acne.<\/p>\n\n\n\n

Several studies have linked low levels of vitamin A to the presence of acne.<\/p>\n\n\n\n

In one study of 200 adults, vitamin A levels were 80 micrograms lower in people who had acne than in those who did not.<\/p>\n\n\n\n

Vitamin A can help reduce acne. Research shows that creams containing vitamin A can reduce the number of acne lesions 50%.9<\/a><\/sup><\/p>\n\n\n\n

The most well-known form of oral vitamin A used to treat acne is isotretinoin. This drug can be very effective in treating acne, but it can have many side effects, including mood changes and birth defects.<\/p>\n\n\n\n

Acne has been linked to low vitamin A levels. Both oral and topical forms of vitamin A are often effective in treating acne, but can have unwanted side effects.<\/p><\/blockquote>\n\n\n\n

Vitamin A overdose<\/strong><\/h2>\n\n\n\n

Vitamin A is valuable for overall health. But too much of it can be dangerous.<\/p>\n\n\n\n

Hypervitaminosis A, or vitamin A toxicity, usually occurs when high doses of supplements are taken over a long period of time. People rarely get too much vitamin A from their daily diet alone.<\/p>\n\n\n\n

Excess vitamin A is stored in the liver and can cause toxicity and problematic symptoms such as vision changes, dry and rough skin, mouth ulcers and confusion.<\/p>\n\n\n\n

Pregnant women should be especially careful not to consume too much vitamin A to avoid possible birth defects.<\/p>\n\n\n\n

Always check with your healthcare provider before taking vitamin A supplements.<\/p>\n\n\n\n

People with certain medical conditions may need higher levels of vitamin A. However, most healthy adults need 700-900 mcg per day. <\/p>\n\n\n\n

Vitamin A toxicity usually occurs from taking too many vitamin A supplements. This can cause serious problems, including vision changes and mouth ulcers.<\/p><\/blockquote>\n\n\n\n

It's important<\/strong><\/h2>\n\n\n\n

Too little vitamin A can cause skin inflammation, infertility, stunted growth and respiratory infections.<\/p>\n\n\n\n

People with wounds and acne may have lower levels of vitamin A in their blood and may benefit from higher doses of vitamin A.<\/p>\n\n\n\n

Vitamin A is found in meat, milk and eggs, as well as in red, orange, yellow and green plant foods. To make sure you get enough vitamin A, eat a variety of these foods.<\/p>\n\n\n\n

If you suspect you have a vitamin A deficiency, talk to your doctor or health care provider. Correcting vitamin A deficiency can be simple with the right foods and supplements.<\/p>\n\n\n\n
