So, what’s a safe dose that will likely get us to the purported optimal level? 1,000 units a day should get most people up to the target 75 nmol/L (which is 30 ng/mL). But by most people, they mean 50%. To get around 85% of the population up to 75 would require 2,000 a day. 2,000 international units a day would shift the curve from here to here. That way, we can take the average person into the desired range without fear of toxicity. You can take too much vitamin D, but you don’t tend to see problems until blood levels get up around 250, which would take consistent daily doses in excess of 10,000.

I take 5k per day and my blood level in July was … 63.2!
