Your levels are perfect! When I first had my levels tested, I was at a 23. After supplementing @ 10K iu for the past 6 months, I am at a 58. My doctor wants me right about at 80.
This was the first time I’ve had my levels tested and I was pleasantly surprised after hearing how hard it is for most people to get into the optimum range. I’ve been debating about what to do next, i.e., maintain, increase, or ease off a little. It sounds like your doc would advise me to keep doing what I’m doing...
