• 4000 IU of Vitamin D is the safe upper limit according to the Institute of Medicine (IOM).
• 10-20 minutes in the sun is recommended generally
• Supplement total needs through foods containing rich sources such as Swordfish; Sockeye Salmon; Tuna canned in water; Beef liver; One large whole egg; Sardines canned in oil and foods commercially available with added Vitamin D.
