60-80? That seems high - I don't think you could be at that without taking a lot of supplements every day.
I think 30 is the lab normal (and it was recently raised to 30 from 20) - though a lot of people are below that when tested.
- narak 7y agoRecent research (as in the last 10 years) seems to suggest that current RDI is at least an order of magnitude lower than it should be. I have no medical background, but anecdotally, it has helped my sleep a lot. I'm generally a supplement skeptic, but currently taking 6k IU a day.

- fossuser 7y agoSure - I’m just skeptical that the optimal level is one you could never get without a lot of supplements. Doesn’t mean that isn’t true, but I’d need more to be persuaded.
