Zoom in on the bottle of vit D, it's 1000IU. I got everyone (not the 4 year old) to take x6 and that's it for the week. Yes you can take a week's allowance in one go.
Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity. This level is many times higher than the U.S. Recommended Dietary Allowance (RDA) for most adults of 600 IU of vitamin D a day.
60,000 Iu would be taking 60 tablets a day how many are in the bottle and would that be a bottle a day?
Quote:The Institute of Medicine's Food and Nutrition Board's old 1997 recommendations suggested that 2,000 IU per day of vitamin D is safe for adults and that 1,000 IU per day is safe for infants up to 12 months of age. Many observers expected a drastic increase in the IOM's 2010 update.
That didn't exactly happen. The IOM committee did increase its "upper level intake" -- that is, the boundary at which it feared vitamin D would become unsafe. That dose is 4,000 IU/day for adults, 3,000 IU/day for kids ages 4-8, 2,500 IU/day for kids ages 1-3, 1,500 IU/day for infants ages 6-12 months, and 1,000 IU/day for infants ages 0-6 months.
But some recent studies suggest that healthy adults can tolerate more than 10,000 IU of vitamin D per day. John Jacob Cannell, MD, executive director of The Vitamin D Council, notes that the skin makes 10,000 IU of vitamin D after 30 minutes of full-body sun exposure. He suggests that 10,000 IU of vitamin D is not toxic.According to the National Institutes of Health, 25-OHD levels that are consistently over 200 ng/mL are "potentially toxic."https://www.webmd.com/osteoporosis/features/the-truth-about-vitamin-d-can-you-ge... 15 minutes on your back followed by 15 minutes face down in the sun while nearly naked gives you 10,000 IU a day it's cheaper than supplements. Most people can handle 10-12 minutes easily without burning.
For best protection you need just over 50 Ng/Ml.
Quote:Recommendations on optimal vitamin D levels vary, but research suggests that levels between 30–60 ng/mL are likely optimal and may help protect against illness and disease
Most cases of vitamin D toxicity are caused by inappropriate supplement dosing and prescription errors.
For example, in a 2020 case report, a 73-year-old man developed vitamin D toxicity after taking 10,000 IU of vitamin D per day for many years
In another 2020 case report, a 56-year-old woman who took an average of 130,000 IU of vitamin D per day for 20 months in hopes of improving symptoms of multiple sclerosis was hospitalized for symptoms including nausea, vomiting, and muscle weakness.
Her vitamin D levels were discovered to be 265 ng/mL (11Trusted Source).
Note that 130,000 IU is over 30 times the generally recommended safe upper limit of 4,000 IU per day.
Keep in mind that people who are low or deficient in vitamin D typically need to take much higher levels than the current Tolerable Upper Intake Level (UL) of 4,000 IU per day to reach and maintain optimal vitamin D levels.a 2015 case study reported that an older man with dementia who received 50,000 IU of vitamin D daily for 6 months was repeatedly hospitalized with symptoms related to high calcium levels
In another case study, an 18-month-old child who was given 50,000 IU of vitamin D3 for 3 months experienced diarrhea, stomach pain, and other symptoms. These symptoms resolved after the child stopped taking the supplements
In a 2021 case report, a 64-year-old man accidentally took 200,000 IU of vitamin D per day because he misunderstood medication instructions. He showed altered mental status and other serious symptoms related to hypercalcemia
Vitamin D deficiency is generally recognized as serum vitamin D levels less than 20 ng/mL. People who have levels that fall between 21–29 ng/mL are considered to have insufficient vitamin D levels
Healthcare professionals may recommend people who are very low in vitamin D take very high weekly doses of 50,000 IU for 8 weeks, followed by a maintenance dose of 2,000 IU per day after their levels reach 30 ng/mL
Make sure to avoid excessive doses of vitamin D. Generally, for people with adequate vitamin D levels, taking supplements of 4,000 IU or fewer per day is considered safe.
