Vit D

There is no substitute for getting your blood levels of vit D measured. Vitamin D3 is the natural version. We UCers are likely to be deficient since we may have problems with absorption. (Actually I think most people are deficient).

Optimal values are between 40 and 60 ng/ml. Measurements near 100 ng/dl are technically safe but that leaves little margin for error since vitamin D can be overdosed. I need to take about 5,000 IU of D3 each day to maintain my blood levels within the optimum range.

5,000 IU may seem excessive but consider one full day at the beach, without sunscreen (if you can avoid getting burned to a crisp), will provide about 25,000 IU. I play a lot of golf outdoors and go to the beach often and still need to supplement.

I'm on 3000 - 4000IU. Was on 5000IU for many years, and my levels are now in optimum range.

Take 1,000 IU of D3 daily, alternating a softgel D3 with Centrum Silver multivitamin that includes D3. This D3 regimen + fortified lactose-free milk in daily diet gives me lab test results for vit D levels in low to mid 30s. (Acceptable per my physicians.) / Old Hat
