Understanding Vitamin A Intake
-
Preformed Vitamin A: This is the type of vitamin A found directly in animal products. The recommended limits for preformed vitamin A are strictly enforced, as excessive amounts can lead to toxicity. Adults shouldn't exceed 3,000 mcg per day of preformed vitamin A. https://www.webmd.com/a-to-z-guides/supplement-guide-vitamin-a
-
Provitamin A Carotenoids: These are found in plant-based foods and are converted into vitamin A by the body as needed. There isn't an upper limit for carotenoids, as the body regulates the conversion process effectively.
-
Sources: Obtain vitamin A from a balanced diet rich in fruits and vegetables (for carotenoids) and animal products (for preformed vitamin A). Examples include: sweet potatoes, carrots, spinach, liver, and dairy products.
-
Supplements: If you are considering vitamin A supplements, consult your doctor. Exceeding the recommended daily allowance, especially of preformed vitamin A, can lead to toxicity. High doses of vitamin A (above 10,000 IU) can cause serious health complications. https://health.clevelandclinic.org/vitamin-a-toxicity If you take supplements, ensure your total daily intake from food and supplements doesn't surpass 1.5 mg (1,500 µg). https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-a/
