My blood level was only 10ng/ml (severely deficient even with the 400 IU in a multivitamin) - After taking 2500 IU for 2 years, it only got up to 35ng/ml which is barely in the non-deficient range.
I just upped my dosage to 5000 IU, which will get it to around 50-60, which is considered by optimal.
1000 units just isn't enough for most people. Generally, it's 30 IU per pound of body weight that's needed.
