There are two primary forms of vitamin A in the diet:
- Retinol or preformed vitamin A: Occurs in animal foods, such as liver, eggs and beef, among others.
- Beta-carotene or provitamin A: Occurs in plant foods, such as sweet potatoes and pumpkin, and gets converted to retinol in the body.
How Much Beta-Carotene Do You Need Per Day?
There's no recommended dietary allowance (RDA) for beta-carotene specifically, but there is one for vitamin A and it differs for people assigned male at birth (AMAB) and people assigned female at birth (AFAB).
The RDA for vitamin A is measured in retinol activity equivalents (RAE). These units account for the fact that not all active vitamin A is derived directly from retinol it can also come from vitamin A precursors like beta-carotene. For example, 1 microgram (mcg) RAE is equivalent to 1 mcg of retinol or 12 mcg of dietary beta-carotene.
The RDA for people AMAB is 900 mcg RAE while the RDA for people AFAB is 700 mcg RAE, per the National Institutes of Health (NIH). Pregnant and lactating people require higher amounts of vitamin A, at 770 and 1,300 mcg RAE, respectively.
Eat whole-food sources of beta-carotene for health benefits like vision support and chronic disease protection. Beta-carotene supplements have been linked to an increased risk of lung cancer in people who smoke or have been exposed to asbestos, per the Mayo Clinic.
1. Sweet Potato: 214% Daily Value (DV)
Sweet potatoes are one of the richest sources of beta-carotene. A nourishing source of complex carbs, 1 cup of baked sweet potato offers an impressive 1,922 mcg RAE or 214 percent of the DV for vitamin A. Enjoy your sweet potato with the skin on for an extra hit of gut-friendly fiber.
Beta-carotene is fat-soluble, so youll improve your bodys absorption of the nutrient if you pair it with a source of healthy fat. Go ahead and drizzle olive oil, tahini, nut butter or another fat-rich food on top of your sweet potatoes to maximize the bioavailability of beta-carotene.
