There is much controversy over dairy but the calcium content is not in dispute. Really just depends upon whether you have the appropriate enzymes to digest it (lactase to digest the lactose) or whether there are allergies (more likely to the casein content) or autoimmune issues which might contraindicate consuming.

One of the more absorbable forms of calcium from supplements is the citrate form which can be taken on an empty stomach.

I can’t take calcium pills (causes extreme constipation which then affects my digestive system), so my Rheumatologist told me to take two or three Tums a day. It seems to be working for me.
