RDI

Recommended Daily Intake. On January 1, 1997, the U.S. Food and Drug Administration (FDA) began phasing in new labeling requirements – which are now official. One of the changes that has caused some confusion is the switch from Recommended Daily Allowance (RDA) to Recommended Daily Intake (RDI). Also, Vitamin and Mineral listings on the labels are now followed by Percentage of Daily Value (%DV). The following is a list of vitamin and minerals with their RDI’s: Vitamin A – 5,000 IU*, Biotin – 300 mcg, Vitamin C – 6O mg, Pantothenic acid – 10mg, Calcium – 1000 mg, Phosphorus – 1000 mg, Iron – 18 mg, Iodine – 150 mcg, Vitamin D – 400 IU, Magnesium – 400 mg, Vitamin E – 30 IU, Zinc – 15 mg, Vitamin K – 80 mcg, Selenium – 70 mcg, Thiamin – 1.5 mg, Copper – 2.0 mg, Riboflavin – 1.7 mg, Manganese – 2.0 mg, Niacin – 20 mg, Chromium – 120 mcg, Vitamin B6 – 2.0 mg, Molybdenum – 75 mcg, Folate (Folic Acid) – 400 mcg, Chloride – 3,400 mg, Vitamin B12 – 6 mcg. (IU = International Units; mcg = micrograms; mg = milligrams; *Vitamin A is also measured in RE’s: 1 RE equals 3.33 International Units (IU) of retinol (active vitamin A) equals 10 IU’s of beta-carotene.)
