I'm taking D3 daily and I'm confused about the DV % that are indicated on the bottles. Why are they so huge?
The 2010 recommended daily allowance (RDA) is 600 IU for those 1-70 years of age. So why so many brands offer 5000 – 10000 UI (1250-2500% Daily Value) per pill? The instruction on the bottle suggests I take one pill daily. I'm positively confused.
Could you please clear up this issue for me?
