appreciate you sharing but just wanted to respond to a couple of things you mentioned. I think we can sometimes get overly concerned with food combinations, especially when it comes to phytates and oxylates. It is true that they can inhibit the absorption of calcium but they don't eliminate the absorption completely. We have to remember that all foods contain a multitude of nutrients and phytochemicals so our bodies are accustomed to processing and extracting what is needed provided digestion is optimal and that we don't rely exclusively on something like spinach as our high-calcium greens. Best to concentrate on consuming a wide variety of whole, nutritious foods and making sure we get enough calcium and the supportive nutrients throughout the day, supplementing only where we fall short so that the body doesn't continually pull calcium from the bones in an effort to regulate blood levels. We can't absorb more than 500 mg at one time so eating a serving of about 300 mg of calcium 3-4 times a day is optimal. Supplementation has possible negative consequences for the accumulation of arterial plaque so best to get your calcium sources from food wherever possible and supplement judiciously only when necessary. I would suggest that your breakfast that includes a cup of kefir provides you with enough calcium to start your day. By taking 600 mgs of calcium supplementation along with your kefir, you are getting approx 900 mg of calcium at one time which is way too much. Kefir is a great calcium source, particularly since it's fermented and easily digested so no need to supplement on top of that.
