I've been analyzing my diet using Fitday recently (32yo male), and noticed that while most of my nutrients vary (some days more than the RDA, some days less), I almost always ran a calcium deficit because I didn't eat many calcium-rich foods (cheese, greens, etc.) I'm correcting that now so I meet my RDA each day, but I'm concerned about all the years where I consumed much less calcium every day than I am now. Should I be concerned? Is this something that I need to make up with extra calcium? Or will I be fine? Thanks.
