@Quincyw33 10,000 is not too much... you may want to go back on many studies here on this group that suggest 10,000 IU daily. 1,000 IU is not nearly enough for people on meds and with Chronic Hep B. There's specific reasons on this. Maybe you were misreading it here, but I am almost certain @stef2011 has had many comments and articles and such about 10,000 IU. Personaly, 5,000- 10,000 IU would be good.
