Just don't go crazy with supplements to the point you put yourself at risk for calcium toxicity in the blood.

Studies show this is a common misconception about sunshine and milk and OJ, etc. being adequate. The levels there were defined to eliminate rickets in children, and this only needs a rather low level in the blood. Something like 4 or 5 times that level is what is said to be a good level for adults to have strong immune systems and such. The only caution seems to be excess calcium build up with mega dosing.
10000 IU per day for example is considered a safe amount for healthy adults.
