Recommended Dietary Allowance

There is not enough data to establish a Recommended Dietary Allowance for chromium. An Adequate Intake (AI) was set as an estimated safe and adequate daily dietary intake for chromium. The AI for men ages 19-50 years is 35 micrograms daily, and for women ages 19-50 years, 25 micrograms daily. Men and women older than 50 years require slightly less, at 30 and 20 micrograms daily, respectively. For pregnancy and lactation, the AI is 30 and 45 micrograms daily. A Tolerable Upper Intake Level (UL) is the maximum daily dose unlikely to cause adverse side effects in the general population. A UL has not been established for chromium, because a toxic level has not been observed from food sources or from longer-term intakes of high-dose supplements.
