How to Improve Absorption of Daily Calcium Intake
Boosting your calcium absorption is just as important as intake.
- Get Enough Vitamin D (sunlight, supplements)
- Avoid Excess Caffeine and soda (reduces calcium absorption)
- Limit High-Oxalate Foods with meals (e.g., spinach blocks calcium)
- Split Calcium Intake (body absorbs 500-600 mg max at a time)
- Exercise Regularly – weight-bearing workouts improve calcium retention
Calcium Supplement vs Food: What You Need to Know
Sometimes diet isn’t enough. Here’s how to decide:
When to Consider Supplements:
- You’re vegan or lactose intolerant
- Osteoporosis diagnosis
- Low dietary intake confirmed by a doctor
Types of Calcium Supplements:
- Calcium Carbonate: Higher calcium content but needs food for absorption
- Calcium Citrate: Absorbs better with or without food
“Always consult your doctor before starting calcium supplements,” advises Dr. Sharon Lee, MD.
