I admit I don’t know at what point the dose becomes unsafe, but I’d imagine that taking a 1000 IU tablet daily plus the additional natural vitamin D intake could be problematic longterm.
Thanks, it looks like vitamin D is definitely one of the harder ones to get too much of naturally.
Other sources suggest much lower upper limits, but still a lot higher than you’re going to get via sunlight and diet.
This study found 3.2% of participants were getting over 4,000 IU daily in 2013-2014 (vs <0.1% about a decade prior). That trend of increased intake has probably continued, so stats for a more recent year would be pretty interesting.
I also didn’t realise you could get vitamin D supplements as high as 10,000 IU without a prescription, so I’m sure there will be people taking that regularly without good reason to do so.
Most multivitamins/supplements/whatever have WAY more than the recommended daily amounts.
RDA is min required to prevent disease. There is also a max dosage, after which it is toxic.
Sure, but going over 100% “daily value” does not equal toxic. You generally have to be taking well over 4000 IU vitamin D daily to reach toxic levels.
Having known people who prefer supplements to actual medical care, I can attest to “megadosing” of vitamins being common in these communities.

For healthy adults, it’s safe
