Micronutrients & recovery
Increasing dietary protein intake improves intestinal calcium absorption and suppresses parathyroid hormone (PTH) secretion, thereby benefiting skeletal health without causing negative calcium balance.
Eating more protein helps your bones by improving how your body absorbs calcium and reducing levels of parathyroid hormone (PTH), which can weaken bones if too high. This benefit occurs without causing bone loss, even though more calcium is excreted in urine.
GoodSupportsHIGH confidence
Recent studies show that the increase in urinary calcium excretion is due to improved intestinal calcium absorption, and high protein diets do not result in negative skeletal calcium balance... Because increasing dietary protein increases intestinal calcium absorption, over time this effect could be beneficial to the skeleton by suppressing PTH secretion.
Why this rating
Based on calcium isotope studies and controlled trials.
