Yes. If you do not get enough calcium in your diet, your body will take it out of your bone. Only supplement your diet if you are not getting the recommended intake for your age and sex.
Yes. No reason not to although with a well balanced diet I wonder as to the benefit of the supplement.
Calcium with coffee. No problem.
Not much. The calcium will bind with the phosphorus in the coffee but the amount of phosphorus is low. If you are taking the calcium as a supplement you'll get much better results to not take within 2-4 hours of a meal or a phosphorus containing beverage.
Should be fine. Calcium does not affect protein absorption and vice versa. You may not any supplement if you can stay on a healthy, balanced diet--see pyramid pictured here. Good diet is important, but regular exercise is also needed for long term good health. So eat well, sleepp well, exercise regularly and see doc for preventive care. Good luck.
Avoid this. Bone mineral density tests measure the amount of mineral in the bone, and this mineral is predominantly calcium. The presence of calcium in your digestive tract may be detected and falsely interpreted as bone mineral, giving an inaccurate increased result.
Nothing. It takes time for calcium to be absorbed into the bone if the body will observe it at all.
Doctors can you tell me how often should I take a calcium supplement as a young male who does not drink milk daily?
Daily. If you are not getting enough vitamin d from your diet you should take vit d3 supplement 1000mcg daily.
Won't hurt. But must be added in to your dietary intake. You need a total of 1000-1500 mg/day. Check w/your doctor and/or a dietitian. Take calcium supplements with meals only.
With citrus juice. Citrus fruits and juices have vitamin c which aid in the absorption of calcium.
Timing. I would not take them right before bed as it could reflux up into your esophagus at night and cause pain and heartburn.
