Vitamins are essential for the development, repair, and maintenance of healthy tissues and cells, with vitamin A being especially critical for vision, skin, and bones.
Vitamin A is a nutrient that is fat-soluble. This means that it is absorbed into the body together with dietary fat and then stored in bodily tissue for future use.
It serves various purposes, including assisting the body's immune system in fighting illness and infection, as well as promoting healthy vision, teeth, skin, bone and soft tissue.
Vitamin A can be obtained naturally through meals or as a supplement. Cheese, eggs, oily salmon, milk, yogurt, and liver are all good sources of vitamin A.
Since the body can convert beta-carotene from plant sources like mango, papaya, and apricots into retinol, these foods can also be a source of vitamin A.
Dietary requirements for healthy men and women aged 19 and above are 900 micrograms (mcg) and 700 mcg, respectively.
The 'Tolerable Upper Intake Level' for people is set at 3,000 mcg of vitamin A per day, therefore it's crucial to avoid taking more than that.
Even while your body can store vitamin A, chronically high levels of vitamin A can harm bone health and raise the risk of osteoporosis.
Overdoes of vitamin A have been linked to a variety of symptoms ranging from skin and hair loss to neurological issues and gastrointestinal concerns.
Vitamin A deficiency can cause blurry vision at night, dry eyes, hair, and mouth, dry and itchy skin, brittle nails, diarrhea, tiredness, and more infections.
In the U.S., vitamin A deficiency is uncommon, but it is common in many developing countries. It's the main reason why kids in Africa and Southeast Asia go blind.
