Recommended Supplement Limits
The U.S Institute of Medicine has established a Tolerable Upper Level of Intake (UL) to protect against vitamin D toxicity. These levels in micrograms (ug) and International Units (IU) for male and female are:
(Conversion : 1 µg = 40 IU and 0.025 µg = 1 IU.)
- 0-6 months: 25 µg (1000 IU)
- 7-12 months: 38 µg (1500 IU)
- 1-3 years: 63 µg (2500 IU)
- 4-8 years:75 µg (3000 IU)
- 9+ years:100 µg (4000 IU)
- Pregnant and Lactating: 100 µg (4000 IU)
The recommended daily allowance is 15 µg/d (600 IU per day). Overdose has been observed at 1,925 µg/d (77,000 IU per day). Acute overdose requires between 15,000 µg/d (600,000 IU per day) and 42,000 µg/d (1,680,000 IU per day) over a period of several days to months, with a safe intake level being 250 µg/d (10,000 IU per day). Foods contain low levels, and have not been known to cause overdose.

Famous quotes containing the words recommended, supplement and/or limits:
“Goldsmith tells us, that when lovely woman stoops to folly, she has nothing to do but to die; and when she stoops to be disagreeable, it is equally to be recommended as a clearer of ill-fame.”
—Jane Austen (1775–1817)
“Japanese food is very pretty and undoubtedly a suitable cuisine in Japan, which is largely populated by people of below average size. Hostesses hell-bent on serving such food to occidentals would be well advised to supplement it with something more substantial and to keep in mind that almost everybody likes french fries.”
—Fran Lebowitz (b. 1975)
“This teaching is not practical in the sense in which the New Testament is. It is not always sound sense in practice. The Brahman never proposes courageously to assault evil, but patiently to starve it out. His active faculties are paralyzed by the idea of caste, of impassable limits of destiny and the tyranny of time.”
—Henry David Thoreau (1817–1862)
