Chris and Xand continue their conversation about calcium with Dr Sagen Zac-Varghese.

The docs want to know about common issues that are seen around calcium and bone health, especially osteoporosis. They want to learn how osteoporosis relates to calcium, who is at risk and why it is more common in women. They also want to know what inspired Sagen’s passion for calcium and what we can learn from astronauts about bone health.
