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.
Seems safe based on this doc. https://youtu.be/uAfVC4l5uZ0
but it seems like need other nutrients that works with d3 to keep it safe or beneficial for the body.
RDA value is just the min required to prevent disease. The toxicity level is much higher.
For healthy adults, it’s safe
