How Calcium Supplements Actually Work in Your Body

Think your calcium supplement is helping your bones? Here's a reality check: most calcium pills are basically crushed rocks that your body can't absorb. In this episode, Sarah Williams breaks down the shocking truth about why 96% of that expensive calcium supplement you're taking might be doing more harm than good. On Fuel Different, we explore how calcium carbonate has only 4% bioavailability in people over 40, why your declining stomach acid makes rock-based minerals even harder to absorb, and where that unabsorbed calcium actually goes (spoiler: your arteries, not your bones). Sarah explains why plant-based calcium sources blow supplements out of the water with 40-60% absorption rates, and what this means for your heart health and longevity. If you've been popping calcium pills thinking you're protecting your bones, this episode will completely change your approach to bone health and nutrition. 📍 Chapters: [00:00] Introduction with Sarah Williams [01:30] The calcium absorption crisis nobody talks about [04:00] Why stomach acid matters more than you think [07:00] Where unabsorbed calcium really goes in your body [10:00] Plant-based vs. supplement calcium showdown [12:00] Better ways to actually build strong bones 🔍 Topics: wellness, nutrition, supplements, bone health, heart disease, diet ⭐ Ready to fuel different?
