I thought so too! We took a “lesson” from a pro. Not that much money, and so fun. I recommend it.
Wish I could have come out with a stronger recommendation re vit D but had to keep it uncertain, because that’s the truth. I did favor one side of the seesaw myself obviously.
So, when I first started reading this, two things popped into my head, vitamin D toxicity and hypercalcemia. In fact, I came across a case study in which someone took 60,000 IU for a several months but it can happen at a lower doses (spousal unit took 3 IU and developed hypercalcemia). However, upon further reading, this is s one time dose. Still, this is a limited study and in need of further data.
I did find this interesting: "Importantly, the results from our study do not imply that photoprotective behaviors should now be substituted for high-dose vitamin D3. The practice of strict photoprotection, including the regular use of sunscreen, remains essential in preventing the acute and chronic effects of UVR, including sunburn, photocarcinogenesis, and photoaging (Lim et al., 2017; Young et al., 2017). Moreover, while frequent sunscreen use does not appear to decrease serum vitamin D3 levels or lead to vitamin D3 deficiency, UVR-mediated vitamin D3 production in the skin is associated with DNA damage (Linos et al., 2012; Petersen et al., 2014)." Unless I am mistaken, suncreen do not interfere with D3 process.
Yes very good points, and the research I am familiar with confirms that sunscreen does not interfere significantly with vit D production. Also, vitamin D supplements have been disappointing in terms of better outcomes for associated problems with deficiency states, so some speculate that low vit D is a good marker for insufficient sunlight exposure, but the benefits of getting a little sun might be mediated by additional mechanisms and enzymes like those listed above.
Keeping any post short is impossible if we really get into the weeds! When I tried to bang this out Wednesday night after a long day in the office, a daunting 215 studies loomed in PubMed regarding “vitamin D and sunburn.” Going to dive back in on another sunscreen/sunburn/vit D post someday soon though:
Careful diving, make sure you can get back up to the surface, it's deep waters. :) Many confounding things like aging and thin skins also affect serum D3. You would think Florida (the Sunshine state) has it share of deficiency among the older population, well, it does..
Lively castle and dragon😀
👌it was worth it!
Thanks!!! That’s an incredible sandcastle & dragon! Appreciate the links, too.

One topic you could mention to your readers is the other danger of summer with tick-borne disease.
