Vitamin A: 1 IU = 0.3 mcg of retinol (or 0.6 mcg of beta-carotene)
Vitamin E: 1 IU = 670 mcg of alpha-tocopherol
Because of this 1000 IU is just not the identical as 1000 mcg—it is determined by the particular vitamin being measured. At all times check with the label to see the precise microgram or milligram equal.
What Is the Distinction Between 50 mcg and 2000 IU?
If you happen to come throughout two vitamin D dietary supplements labeled as 50 mcg and a pair of,000 IU, they’re truly the identical dose. Utilizing the conversion system (1 IU = 0.025 mcg), you may decide that 2,000 IU of vitamin D is equal to 50 mcg. That is why it’s important to grasp unit conversions when selecting dietary supplements.
