Calcium is a very important mineral for your body, and it's not just for bones. Dr. Martin says it’s better to get calcium through your food and not by supplementing, as it doesn't get to its intended destination this way. Dr. Martin looked at a study on bioavailability, which is a fancy word for how much nutrients our body can absorb. If you ate a bowl of spinach, which has 115 milligrams of calcium, only 5% of that is getting absorbed. Whereas if you take a single piece of cheese, to get the same bioavailability, you’d need to consume 16 cups of spinach! Join Dr. Martin as he teaches on bioavailability in today’s episode, to help you better understand the nutritional needs of your body.
