I was trying to find my way through the labrynth of bunny holes that extends back to around 1991 to figure out what are the TRUE appropriate doses for common, key nutrients like Vitamin D, A etc. It took hours, I lost much of my work by accidentally closing a tab. In general it was beginning to look like the CDC/NIH may have intentionally set the Recommended daily allowances for those nutrients too low (Like Vitamin D3)and then I found a table that seems to indicate that the RDA for babies aged 1 -3 and children were set above the upper safety limit (UL)
https://www.consumerlab.com/rdas/
NIH's National Academy of Sciences created the medical regime's Recommended Daily Allowance levels for supplements through collaborative stupidity they don't want to talk about.
So I skimmed a 1000+ page document on the recommended daily dose for Vitamin D3 and Calcium (only the NIH is not really using the RDA. The NIH doesn't talk about its true DRI units).
Have a look at the NIH's logo NSA shown in the D3 document (Page iii of the front matter)
https://nap.nationalacademies.org/read/13050/chapter/1#iii
There's also a quote above the logo on that page which used to inspire me, but after seeing that logo, it just makes me wonder if it's the medical version of 'As above, so below'.
So a new contender for nightmares emerges, and the heroic LittleLinda is off the hook.
I did find some articles about dosing -stuff I didn't know about taking vitamin A and other supplements. I thought this one was most informative.

Harvard's comes in second. That big table was second to none.

I suspect the upper limit (UL) dosages which are higher for adults compared with RDA are probably correct -it's just odd I can't find out who established and maintains the UL dose recommendations, and they've changed their recommendations in the past 5 years. Have no idea if it's trust worthy, but it could useful to know. For example, the CDC/NIH recommends 700 IU of Vitamin A per day, but the safe upper limit (UL) says the maximum safe does is 3000mcg per day. We were lucky to have protocols by wonderful doctors to advise us on safe levels for the pandemic; God bless them and their sacrifices
KNowing actual safe upper limits could be useful one day, if it's valid information.
I was surprised how much information was either new to me or seemingly meant to distractand confuse; the CDC/NIH have no interest in communicating with the public or educating us on simple,available solutions to protect us or national security.
Welp, prayer will wash that logo away until the next time I see snakes on government reports.
Vitamin D needs are also complicated by a person’s BMI (body mass index). My understanding is that VD needs to be in the blood so it can be transported to and through the organs that need it for optimal function. However, VD tends to gravitate to body fat and gets stored there, becoming less bioavailable. So, the fatter we get, the more VD we need to compensate for the storage tendency. Health authorities may not have been taking this into account when setting the RDA’s and, since we’re generally fatter as a population than we were when the RDA’s were initially set, they need to be higher, probably much higher for some.
