Antibiotics, laxatives, and some cholesterol-lowering drugs interfere with the body's absorption of Vitamin A. Overdose of Vitamin A (over 100,000 IU daily for a long period of time) can be toxic to the body, particularly to the liver, and can cause birth defects.
Carotenoids are a class of compounds related to Vitamin A that are found in dark colored plant foods. One commonly known carotenoid is beta-carotene, others are lycopene and lutein. Beta-carotene has been shown to help prevent cancer by scavenging for free radicals. You cannot overdose on beta-carotene but if you take in too much your skin may turn slightly yellow-orange in color.
Supplementation is important today because while we were created to get all the nutrients we need for healthy lives through our food, our commercialized food supply today does not provide the same volume of important nutrients that it once did. Due to poor commercial farming practices, depleted soils and premature harvesting, our produce is not as nutritious as Grandma's produce was. It is important that we supplement our diets with food based supplements because our bodies don't appreciate synthetic copy-cats.
