Not enough.
Your target should be over 50. ( and some think closer to 80)
400IU is the current RDA which is about 10 times too low.

Why bother testing if the doctor gives a poor recommendation?

Begin taking vitamin D at least eight weeks prior to being tested. This will help you customize your dose once you receive your test results. To determine a basic, starting dose, it has been suggested, as per Dr. John Cannell of the Vitamin D Council (7), that you take 1,000 IU per 25 pounds of body weight. A person who weighs 150 pounds, for instance, would take 6,000 IU per day as a starting dose (150/25 = 6. 1,000 x 6 = 6,000). Do this for at least eight weeks, and then test. Perhaps this dose will put you in the ideal range, but there`s no guarantee since we are all so different, and have unique vitamin D receptor genotypes. The idea is to hopefully get somewhere in the ballpark with this method and then tweak your daily dose once the test results come back. If your results are still suboptimal, Dr. Cannell has estimated that each 1,000 IU increase in supplemental vitamin D will generally produce a 10 ng/ml increase in the vitamin D blood level (8). For example, if you have been taking 5,000 IU per day for 8+ weeks, and your results come back at 40 ng/ml, you would want to increase your dose to at least 7,000 IU (2,000 IU = ~20 ng/ml rise in blood level) to achieve a minimum of 60 ng/ml. Again, keep in mind that this is necessarily generalized, and additional blood testing every several months is recommended to further customize the dose appropriate to you.

This is similar to the B12 problems we see on this forum every day. Testing... using a low cutoff point.
Then giving a shot once a month--or saying 190 B12 is normal. Its totally
Ineffective.
Knowing what Alan's test result is, you can decide how much to take, and get retested.
