re taking more than 600 mg calcium, it should be split into 2 doses, since the body can only absorb 600
mg at one time - you can take 600
mg at dinner time and 600 mg at bedtime. There's no need to limit dairy to dinner time... that amount of calcium isn't going to affect your thyroid med, unless you're drinking an entire gallon milk or something outrageous. It's perfectly okay to have a cup of milk with cereal, milk in your coffee, cook with it, etc.
