I have been using the Rep-cal and Herptivite for a few years now but have been considering switching to Miner-all. When I was comparing the ingredients, the one thing I noticed is that the Vitamin D3 is listed as 400,000 IU/kg on the Rep-cal and on the Miner-all the Vitamin D3 is listed as 4,400.00 IU per kilo. Can anyone explain this to me? I know many of you use Miner-all so I thought someone would know. Thanks.
