Also included should be chelated magnesium (best to spread doses out over the day) and fish oil. Vitmain A (fat soluble form) provides balance to vitamin D, if you are worried about toxicity. Cod liver oil can be a great whole food source of vitamin D, since it contains a ratio of both D3/A. 5000 iu's is considered to be a maintenance dose for most people. Re the side effects of heart palps, anxiety, etc., some do much better with a dry form of D3 instead of oil based. Supplementing with D2 instead of D3 can also cause these types of side effects.
