Are you getting enough Vitamin A? It’s an essential nutrient vital for vision, immune function, and skin health. Signs of deficiency include poor night vision, dry skin and hair, frequent infections, slow wound healing, and dry eyes.
Vitamin A is an essential fat-soluble nutrient that typically plays a critical role in maintaining vision, body growth, immune function, and reproductive health. It’s available in two primary forms: preformed vitamin A, normally found in animal products, and provitamin A, typically found in fruits and vegetables.
However, when your intake of this vital vitamin is insufficient, you may begin to experience certain signs and symptoms.
Here are five signs that you might not be getting enough Vitamin A:

1. Poor Night Vision
One of the earlier symptoms of vitamin A deficiency can be difficulty seeing in low light or darkness.
Vitamin A forms a component of the protein rhodopsin, which the eye needs to see in lower light conditions.
If you find that your night vision is not what it used to be, a lack of Vitamin A might be the cause.
In a study involving women who experienced night blindness, researchers provided them with vitamin A either through food or supplements.
Both forms of vitamin A proved to be effective in improving the condition. After six weeks of treatment, the women’s ability to adapt to darkness increased by more than 50%.
2. Dry Skin and Hair
Vitamin A naturally helps in the production of sebum, an oily substance that moisturizes our skin and keeps it healthy.
If you’re not getting enough Vitamin A, you might notice that your skin becomes dry and itchy.
Similarly, your hair might also become dry and brittle due to insufficient sebum production.
3. Frequent Infections
Vitamin A plays a crucial role in maintaining the health of our skin and mucous membranes, our body’s first line of defense against infections.
A deficiency in Vitamin A can weaken these barriers, leading to frequent infections, particularly in the skin and respiratory system.
For example, a study conducted with elderly individuals found that having high levels of beta-carotene, a substance that can be converted into vitamin A in the body, in the blood may provide protection against acute respiratory infections.
4. Poor Wound Healing
If you find that your cuts and scrapes are healing more slowly than usual, it could be due to a lack of Vitamin A.
This nutrient plays a key role in the production of collagen, a protein that’s essential for skin repair and regeneration.
5. Dry Eyes
A more severe sign of Vitamin A deficiency is xerophthalmia, a condition characterized by dry eyes. In extreme cases, it can lead to night blindness and even total blindness.
This condition occurs when there isn’t enough Vitamin A to produce the moisture that normally keeps your eyes healthy and lubricated.
If you’re experiencing any of these symptoms, it’s important to talk to your healthcare provider. They can guide you on how to increase your Vitamin A intake, either through diet or supplements, to correct the deficiency and avoid long-term complications.
As always, the key to maintaining good health is a well-balanced diet that includes a variety of nutrients, including Vitamin A.
Frequently Asked Questions
What are the reasons for Vitamin A deficiency?
The main reasons for Vitamin A deficiency include:
- Inadequate intake of foods rich in Vitamin A, like dairy products, leafy green vegetables, and certain fruits.
- Problems with absorption in the digestive tract due to diseases like celiac disease, Crohn’s disease, or pancreatic disorders.
- Excessive consumption of alcohol interferes with the body’s ability to utilize Vitamin A.
How can I increase my Vitamin A intake?
You can increase your Vitamin A intake through your diet or supplements:
- Sweet potatoes
- Spinach and other leafy green vegetables
- Red peppers
- Dairy products like milk and cheese
- Fish such as salmon and trout
- Liver and other organ meats
You can take Vitamin A supplements if recommended by your healthcare provider. However, it’s essential not to exceed the recommended daily intake, as too much Vitamin A can be harmful.
How can I confirm if I’m deficient in Vitamin A?
If you suspect you’re deficient in Vitamin A, it’s important to speak to a healthcare professional. They may order a blood test to check the levels of Vitamin A in your body.
This is the most reliable way to confirm a Vitamin A deficiency. They can also provide you with advice and treatment options if you are indeed deficient.
Can Vitamin A deficiency be life-threatening?
While Vitamin A deficiency is not typically life-threatening in itself, it can lead to severe health issues if left untreated.
This includes permanent damage to the eyes that can lead to blindness, severe skin issues, and a significantly weakened immune system, making you more susceptible to life-threatening infections.
Hence, it’s crucial to treat Vitamin A deficiency promptly.
