Do not exceed the UL of 4,000 IU (100 mcg) without consulting a doctor or dietitian. Over time, even amounts less than the UL could potentially have negative health effects ( 7 ).Up to 4,000 IU per day is generally considered the safe upper limit, however, doses up to 10,000 IU/day have not been shown to cause toxicity.
