Don't buy it in capsule form. There isn't enough turmeric there to do any good. You can get your kids to drink it and enjoy it if you make what they call golden milk in India.
Use a smell sauce pan and tilt it so you are using only a small part. Put a tablespoon or two of powdered turmeric into the sauce pan and add enough water to form a thin paste. Set your burner on low. Let it bubble for a few minutes while stirring and add a small amount of water if necessary. Cooking it first like this will bring out the ingredients you want. Put the simmered paste into a mug and add either maple syrup or honey, then fill with milk. Put it into a microwave and warm the milk. Don't boil it, just warm it. Now stir it up and you have a delicious drink for you or the kids.
