RDA, DV (Daily Value), AI, UL... What Does It All Mean?!

RDA, DV (Daily Value), AI, UL... What Does It All Mean?!

“Supplement Facts,” it says in big black letters.

Okay, I get that.

“Serving Size

Alright, I’m still with you.

But then… things start to get… strange…

Is it a foreign language?

Some mysterious code transmitted by scientists in white lab coats who haven’t seen the light of day in weeks?

What do these abbreviations mean?! Will I ever figure it out? Am I supposed to? Does it matter?!

Trying to decipher the back label of a vitamin or supplement bottle may feel like a task that’s not for the faint of heart. And while you may need a chemistry degree to parse out the exact meaning of “Docosahexaenoic Acid,” you don’t need any special training to learn how to safely use vitamins and supplements.

4 Back-of-Label Descriptions You Can Understand!

Let’s talk about some of the abbreviations you might see on a vitamin or supplement bottle. These definitions are taken from National Institutes of Health Office of Dietary Supplements

  • RDA (Recommended Daily Allowances): “average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy people.”
  • AI (Adequate Intakes): “established when evidence is insufficient to develop an RDA and is set at a level assumed to ensure nutritional adequacy.” In other words, if no RDA has been determined, then the label may use AI instead.
  • DV (Daily Value): Daily value is typically the equivalent of an RDA (or an AI if an RDA does not exist for a particular supplement). DV is displayed as a percentage. So, in the case of this calcium supplement, the serving size of 1 tablet offers 60% of the calcium your body needs for the day.
  • UL (Tolerable Upper Intake Level): “maximum daily intake unlikely to cause adverse health effects.” You don’t want to consume more of a vitamin or supplement in a day than what’s listed as the UL.

Not too complicated, right? DV is the indicator you’ll see on many nutrients and supplements.
