On: Is vitamin D really a cure-all, and how should we get our fix?

That is awesome that you were able to get funding for a large study of vitamin supplements. I wish there were more studies like this to identify whether supplements are beneficial beyond placebo (or potentially harmful).

One question: blind or double blind? Does the distributor also not know which product is being given to the patient?

I look forward to the results!

The link said triple blind, technically -- ”Masking: Triple (Participant, Investigator, Outcomes Assessor)”

Thank you. The tables were screwy on my phone.
