Question: Could low-normal phosphorus be from my calcium intake?Given that your calcium is coming from milk and yogurt and Traditional Foods Market brand whole bone meal to get your calcium, you're definitely consuming plenty of phosphorus, and so I don't think your dietary phosphorus is off. I wouldn't really worry about the phosphorus being low in that range. It's not low, it's on the low end of the range. I think the PTH being suppressed to 18 is great. I think the calcium doing that is great. I think that the calcium did that, even when all your calcium sources were balanced by phosphorus, sounds really good because phosphorus would do the opposite.  If you would like to be part of the next live Ask Me Anything About Nutrition, sign up for the CMJ Masterpass, which includes access to these live Zoom sessions, premium features on all my content, and hundreds of dollars of exclusive discounts.
