15 I.U. Vitamin E = 10mg, so 400 I.U. would =266.67 mg. (400/15x10=266.67). The World Health Organization sets the I.U. (International Units) for some medications, and vitamins, each of these has a different I.U. to mg ratio, and you have to find a reference to this ratio to be able to convert I.U to milligrams. It depends on hat the Vitamin E is as, example dl-alpha tocopheryl or dl-alpha tocopheryl acetate, check the chart on the following link for more info
10,000 IU of vitamin A is equivalent to 3,000 mcg.
Recalculate it from the IU-definition for VitA, but be sure the difference betweenretinol (C20H30O) and β-carotene (C40H56), both can be taken to be Vitamin A!By definition for Vitamin A:1 IU vitamin A is the biological equivalent of 0.3 μg retinol, or of 0.6 μg β-caroteneExamples:6 μg of dietary β-carotene is equivalent to 3⅓ IU of vitamin A and is equivalent to 3⅓ IU of vitamin A.This same amount also supplies the equivalent of 1 μg of retinol (or 1 RE =Retinol Equivalent) and is also equivalent to 3⅓ IU of vitamin A.So 5000 IU is 1500 μg retinol or 3000 μg β-carotene
1 IU is the biological equivalent of about 0.667 mg d-alpha-tocopherol (2/3 mg exactly), or of 1 mg of dl-alpha-tocopherol acetate
Melatonin is available over the counter in varying doses of up to 3 mg per tablet. However, a fraction of this is required for insomnia, usually about 0.3 mg or less.
Vitamin A - 310 IU Vitamin C - 174 mg Folate (important during pregnancy) - 67 mcg Vitamin B2 - .09 mg Niacin - .9 mg Vitamin B6 - .16 mg Vitamin E - 3 IU Potassium - 588 mg Phosphorus - 71 mg Magnesium - 53 mg Calcium - 46 mg Selenium - 1.1 mg Iron - .72 mg Zinc - .3 mg Copper - .3 mg
To convert mcg to mg: Divide by 1000 OR multiply by 0.001 OR move the decimal 3 places to the left (they all mean the same thing), so 500mcg = .5mg. Similarly, 1000mcg = 1mg, 2500mcg = 2.5mg, etc. AND to convert in the opposite direction, mg to mcg, multiply by 1000, so 3mg = 3000mcg, 1.5mg = 1500mcg, etc.
No. There are 1000 micrograms in 1 milligram. 3 mg = 3,000 mcg 900 mcg = 0.9 mg
There are 1,000 micrograms (mcg) per milligram.So, 3mcg = 3 / 1,000 = 0.003mg
The original person who answered this stated it was 400IU...This is wrong and could possibly be a grave mistake if someone were to follow this crap answer. each ONE mg = 40,000 IU whoever answered this is playing around in things they shouldn't touch. 4000 mg would be 160,000,000 IU and would be a fatal dose of vitamin D. ALWAYS go look for other answers before you trust the first thing you find people.
Melatonin 3 mg typically lasts about 4 to 8 hours in the body, depending on individual factors such as metabolism, age, and sensitivity to the hormone. It is commonly used to help regulate sleep cycles and may be effective for promoting sleep onset. However, the duration of its effects can vary, so some individuals might experience shorter or longer effects. It's important to consult a healthcare provider for personalized advice on melatonin use.
Light therapy usually results in earlier bedtimes.
