Carlson Vitamin D3 5,000 IU, 125 mcg 120 Soft Gels

Current vitamin D3 Dietary Reference Intakes by the Institute of Medicine range from 200 to 600 IU per day, depending on age. The U.S. Recommended Dietary Allowance (RDA) for infants and children is 400 IU. The upper limit for adults is 4,000 IU per day, but because vitamin D3 is vital for many body functions, some researchers have called for an increase in the RDI.
