Hi migizii, was it you I just told that my nutritionist told me to take 5g of fat w/ the supplements b/c the fat enables the vit Ds to help the calcium do it's thing? Avacado, teaspoon of oil, something like that. I take New Chapter Bone Strength which has all the Ds and Ks and, Strontium. It's a plant based algae calcium which is easier to digest if I'm understanding it correcty. Take good care and warm regards, Sunnyflower
