Beware that curcurmin supplements can have high lead levels due to spiking with lead chromate for coloring high up in the supply chain. It's why I won't take it unless I can find a reliable brand that specifically tests for it. If you do take it, it's good to take with piperine (or just black pepper) for bioavailability.

Have any recommendations?

  Unfortunately, no, although I didn't do a very exhaustive search.

    I was searching around on the subject and came across https://nootropicsdepot.com/longvida-curcumin-capsules/ https://nootropicsdepot.com/longvida-curcumin-capsules/ via Reddit which claims to do testing on their products with an in-house lab: https://nootropicsdepot.com/in-house-analytical-laboratory/ https://nootropicsdepot.com/in-house-analytical-laboratory/. Lead is mentioned but I don't know if lead chromate would be excluded from such a test. Looks more legitimate than most simple resellers but it could just be good marketing.

      FYI longvida is a brand name from a third party (Verdure Sciences), and ND is the reseller that claims to own and operate an internal testing lab.

Does powdered turmeric have the same issue? My parents eat loads of that stuff.

  Unfortunately yes: https://news.stanford.edu/2019/09/24/lead-found-turmeric/ https://news.stanford.edu/2019/09/24/lead-found-turmeric/ Though this article says it is specific to Bangladesh.

On this topic: for anyone generally concerned about their heavy metal levels, hit the sauna & sweat'em out. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3312275/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3312275/

  Huh, fascinating. Apparently sauna use is associated with less heart disease risk too. As someone who tends not to sweat much (despite exercising), maybe I’ll consider this. What does one…..do in a spa, if not going with friends? Sit and contemplate? https://www.health.harvard.edu/blog/sauna-use-linked-longer-life-fewer-fatal-heart-problems-201502257755 https://www.health.harvard.edu/blog/sauna-use-linked-longer-...

    Research isn’t sufficient yet, largely due to lack of random data, but saunas appear to be very good for people. At least, those who are healthy enough to use them already. There’s no data I know of showing that healthy people shouldn’t use them. There is data showing that people with a sauna habit typically live healthier lives. The tricky part is, do healthier people develop the habit, or does the habit make them healthy?

      Anyone read about the impact on male fertility due to the heat exposure? I've heard about it in passing but don't know if it's a real risk.

        Yeah heat definitely reduces sperm counts. One study found it reversed at six months. https://pubmed.ncbi.nlm.nih.gov/23411620/ https://pubmed.ncbi.nlm.nih.gov/23411620/

On lead: I think that’s true of a lot of spices. On black pepper: sure, but curcumin like Meriva absorbs even better. Meriva is sort of like the creapure (aka German creatine) of curcumin. On a brand to use/look at: I like solaray/jarrow/now. Jarrow meriva is what I use and they claim to test all products for heavy metals, but dont have COA (certificates of analysis) readily available so ¯\_(ツ)_/¯
