LovinMe2013 21 Posted February 26, 2013 I'm confused about what Vitamins can be taken with what. Can I take my flintstone Vitamin & then drink a Protein Shake with skim milk? Will the Calcium & the milk effect the Iron in the vitamin? Share this post Link to post Share on other sites
TheGamer 406 Posted February 26, 2013 Calcium inhibits Iron absorption, so they should be taken at different times. I say this as an anemic person who has to take a ton of iron every day Share this post Link to post Share on other sites
