Tag: Ie

According to reputable sources like RxList, the abbreviation IE, often seen on international nutritional labels, stands for 'International Unit'. This metric is a standardized measure of the biological activity of specific substances, which can often confuse consumers accustomed to weight-based units like milligrams (mg) or micrograms (mcg).

According to the National Institutes of Health, International Units (IU) measure the biological activity and potency of certain vitamins like A, D, and E. This makes understanding what does IE stand for in vitamins a key part of interpreting supplement labels accurately. The abbreviation IE is a lesser-used variant of IU, both referring to International Units.
