- Stanfield advises against calcium supplements, citing a ~30% increase in heart attack risk from a 2010 meta-analysis and links to kidney stones and cardiovascular issues. - He emphasizes dietary calcium as the safe alternative, recommending ~1,000 mg/day from food sources rather than pills. - No evidence of personal consumption or specific dosing protocols discussed.
Benefits
- Calcium is critical for building and repairing teeth. - One meta-analysis found reduced fracture risks with calcium supplements, though Stanfield weighs this against cardiovascular harms. - Protein works synergistically with calcium to strengthen bones, especially important during aging.
Best Practices
- Recommends ~1,000 mg/day of calcium from dietary sources, not supplements. - Dietary calcium doesn't spike blood calcium levels the way supplements do, making it safer. - How you get calcium matters more than total intake — food sources are definitively preferred over pills.
Cautions
- A 2010 meta-analysis found calcium supplements increased heart attack rates by ~30%; Stanfield lists calcium among supplements that do "more harm than good." - Excess supplemental calcium can cause kidney stones and cardiovascular issues — likened to "putting too many bricks on a fragile shelf." - Some trials showed no significant bone strength improvement even among participants taking calcium supplements.
