Why are some vitamins sometimes listed as 1500% of your RDI? and wouldn’t that be damaging to your body?

One thing to keep in mind is that our bodies are not perfect at absorbing the substances from our food. So just because a vitamin has 1500% does not mean that all of that makes it into your body. Some exits the body via urine, sweat, respiration, or just never gets digested and gets pooped out. It is very difficult to get sick from vitamin toxicity using *natural* food based vitamin sources, with the notable exception of polar bear liver for example. For synthetic vitamin sources like multivitamins, vitamin toxicity is a more present danger but you would need to be surpassing the recommended dosage for the vitamin supplements. Especially with multivitamins, you don’t take in everything that is listed on the bottle because vitamins and minerals can “compete” so to speak for absorption in the body. Which makes it hard to “overdose” if you’re taking vitamins as directed.
