Vitamin A does more than just boost collagen for smoother, firmer skin. This fat-soluble vitamin is vital for overall health, supporting our immune system, cell growth, and more, says Samantha Dieras, RN, DCN, director of ambulatory nutrition services at Mount Sinai Hospital. She emphasizes that eating whole foods rich in vitamin A is the best way to ensure you get enough.
It’s easy to include vitamin A-rich foods in your diet, whether you’re vegetarian, vegan, or have no dietary restrictions. Here are some of the top sources:
Key Points:
– Vitamin A is crucial for immune function and the health of lungs, eyes, and other organs.
– Whole foods are the ideal source for meeting your daily vitamin A needs.
– Top foods include beef liver, spinach, carrots, and milk.
– The recommended daily intake is 900 mcg for adult men and 700 mcg for women.
Beef Liver: With 6,582 mcg per 3-ounce pan-fried serving, it’s the richest source—providing 731% of the daily value—so enjoy it in moderation.
Sweet Potato: One whole sweet potato offers 1,403 mcg of vitamin A.
Spinach: Packed with nutrients like magnesium and vitamins A, C, E, and K, half a cup of spinach contains 573 mcg of vitamin A.
Carrots: Half a cup of raw carrots provides 488 mcg.
Milk: A cup of skim milk not only supplies calcium and vitamin D but also 149 mcg of vitamin A.
Cheese: Half a cup of ricotta cheese has 133 mcg of vitamin A.
Peppers: Half a cup of sweet or red peppers contains 117 mcg, adding both flavor and nutrition.
Eggs: One hard-boiled egg offers 75 mcg of vitamin A, along with protein.
Tuna: Canned tuna provides 20 mcg of vitamin A and is rich in other nutrients.
Salmon: A 3-ounce cooked serving contains 59 mcg of vitamin A, making it a nutritious choice.
Chicken: While lower in vitamin A (5 mcg in half a breast), it’s a valuable source of protein and other nutrients.
What Does Vitamin A Do?
Vitamin A supports immune function, cell growth, and the health of organs like the lungs and eyes, as well as reproductive systems. For skin, it aids anti-aging through retinol, which boosts collagen, reduces acne, brightens complexion, and promotes skin cell renewal for a smoother texture.
Daily Vitamin A Requirements
There are two types: preformed vitamin A from animal products and provitamin A from plant sources.Foods like dairy, eggs, fish, and organ meats are rich in preformed vitamin A. Plant sources provide provitamin A through antioxidants called carotenoids, including beta-carotene, alpha-carotene, and beta-cryptoxanthin. Individual needs vary, but generally, the recommended daily intake of vitamin A is 900 mcg for adult men and 700 mcg for women, according to Dieras.
How much vitamin A is too much?
It’s important to be cautious with vitamin A intake because your body stores excess amounts rather than excreting them. There’s a safe upper limit, and exceeding it can cause serious side effects. The US Department of Health & Human Services advises adults not to consume more than 3,000 mcg per day.
Regularly taking too much vitamin A can lead to hypervitaminosis A, with symptoms such as fatigue, headaches, blurred vision, nausea, dizziness, depression, joint and muscle pain, poor coordination, or dry skin.
Also, be aware of how vitamin A interacts with medications. Weight loss drugs like Orlistat may reduce the absorption of fat-soluble vitamins like vitamin A, while prescription retinoids can raise the risk of hypervitaminosis. Talk to your doctor to manage your vitamin A intake alongside any necessary medications.
How can I tell if I’m getting enough vitamin A?
Vitamin A deficiency is uncommon, but when it occurs, it can have serious effects. The most typical sign is xerophthalmia, an eye condition causing night blindness, difficulty seeing in dim light, and potential blindness. Other indicators include abnormal lung development, respiratory issues, and anemia.
Those at highest risk for deficiency include premature babies, children, pregnant or breastfeeding individuals, and people with cystic fibrosis or gastrointestinal disorders that affect vitamin absorption.
Do I need a vitamin A supplement?
As with any supplement, Dieras recommends consulting your doctor to check for a deficiency. Since it’s possible to get too much vitamin A, your physician can confirm if you’re lacking and whether a supplement would help. “If you take a supplement, monitoring your vitamin A levels is crucial to avoid excess storage in the body,” she advises.
