Do you ever find yourself cutting evening plans short so you can race home while it’s still light outside? As we get older our eyes change, and the moonlit drives you once enjoyed may now fill you with anxiety. A variety of factors can cause night blindness, but it’s possible that your diet may be lacking vitamin A. Find out how vitamin A affects your eyes and what you can do to get enough of it.
Vitamin A is one of the 13 essential vitamins you need in your diet because your body cannot make enough on its own.
Along with being essential, vitamin A is a fat-soluble vitamin, which means it is stored in your liver or fat tissue. Since these vitamins are not easily flushed from your body like water-soluble vitamins, they have the potential to accumulate and cause toxic side effects. However, there is no need to stress since vitamin A toxicity is uncommon, and you would have to take excessively high amounts to reach toxic levels.
Aside from ocular health, vitamin A supports immunity, bone strength, and cellular functions.
There are two forms of vitamin A:
Although retinoids are 6 times more bioavailable, carotenoids have unique, beneficial functions as antioxidants and may aid in the prevention of some chronic illnesses.
You can also get vitamin A in nutritional supplements. Supplementing your diet with vitamin A using MICROGEL™ technology is best for optimal absorption. This delivery system allows you to fully absorb nutrients into your bloodstream and then into your cells, where they work to improve health. Healthycell’s Bioactive Multi includes vitamin A in both carotenoid and retinoid forms pre-dissolved in sunflower oil and then suspended in a prebiotic gel for maximum absorption.
Everyone is different, and certain factors such as your age, sex, or health will affect your unique nutritional needs. To provide a general guide, the Food and Nutrition Board (FNB) established the Recommended Dietary Allowance (RDA) to meet the needs of most healthy individuals. Since the different forms of vitamin A are not equally absorbed, the RDA is expressed in micrograms of retinol activity equivalents (RAE) to account for the total vitamin content of the retinoid and carotenoid forms.
Vitamin A RDA :
If you have a preexisting health condition or concern or take prescription medication, it’s important to talk to your doctor or registered dietitian about your nutrition, especially when choosing which supplements and dosages are optimal for your health.
Since vitamin A is a fat-soluble vitamin that is stored in your body, it can become toxic when taken in large amounts. Toxicity is uncommon but can produce adverse effects, which is why a tolerable upper intake level (UL) has been established:
Toxicity side effects can start with a harmless yellowing of the skin called hypercarotenemia. But more serious side effects can also develop. Excessive consumption can lead to a condition called hypervitaminosis A, which causes complications to eye, liver, and bone health. Other symptoms include nausea, drowsiness, headache, dry skin, hair loss, and muscle and bone pain.
Vitamin A deficiency is uncommon in the United States but more prevalent in developing countries due to the limited access to vitamin A rich foods. Deficiency may also be seen in individuals who consume vegetarian diets or struggle with alcoholism or drug abuse. Individuals with malabsorption conditions or those diagnosed with HIV/AIDS may also develop a vitamin A deficiency.
Inadequate intake can lead to a weakened immune system, hardening or drying of the skin, or vitamin A deficiency disorder (VADD). VADD mostly affects children and is characterized by the following symptoms:
