RDA = Recommended Dietary Allowance. UL = Tolerable Upper Intake Level. Exceeding the UL long-term may cause the toxicity symptoms described above.
High doses (above 400 IU/day) can interfere with blood clotting, especially if you take warfarin, aspirin, or other blood thinners. The UL is 1,000 mg/day (about 1,500 IU), but experts recommend not exceeding 400 IU/day if you take anticoagulants.
