ICMR Beta Carotene to Vitamin A Ratio
The Indian Council of Medical Research (ICMR) guidelines from 2010 specify the conversion ratio for beta carotene to vitamin A (retinol) for dietary purposes.
According to ICMR (2010), the recommended conversion ratio is:
- Beta Carotene : Vitamin A (Retinol) = 1 : 8
This means that 8 micrograms (mcg) of dietary beta carotene are considered equivalent to 1 microgram (mcg) of retinol activity.
Therefore, the correct conversion ratio is 1:8.
