DWQA Questions › Tag: bioavailable vitamin D3Filter:AllOpenResolvedClosedUnansweredSort byViewsAnswersVotesYou have told us that taking 2,000 IU of vitamin D3 is safe and very helpful, because the Recommended Daily Allowance, as with many essential nutrients, is way too low. I have seen doctor recommendations that say when health issues are present it is meaningful and safe to take as much as 10,000 IU of vitamin D3. I have been taking 5,000 IU twice a day. Is that safe and useful for me and others? What is most important for us to know?ClosedNicola asked 2 days ago • Healing Modalities18 views0 answers0 votesIs the commercial source of Vitamin D3 (5000 IU with Coconut MCT Oil per capsule) an effective source for delivering bioavailable vitamin D3, and is it superior to taking the vitamin in pill form? Is the need for a special formulation of vitamin D3 for adequate bioavailability mostly hype and really a nonissue?ClosedNicola asked 1 year ago • Healing Modalities287 views0 answers0 votes
