Calcium is the most abundant mineral in the body, with about 99% stored in bones and teeth. Key benefits include:
- Bone and Teeth Strength: Helps maintain bone density and may reduce the risk of osteoporosis as we age.
- Muscle Function: Essential for proper muscle contraction and relaxation.
- Nerve Transmission: Supports communication between the brain and the rest of the body.
- Heart Health: Helps regulate normal heart rhythm and blood pressure.
- Blood Clotting: Plays a role in the body’s natural clotting process.
You may benefit from extra calcium if you:
- Are postmenopausal women (due to declining estrogen levels)
- Follow a dairy-free, vegan, or low-dairy diet
- Are over 50 years old
- Have limited sun exposure (which can affect Vitamin D levels needed for calcium absorption)
- Have a family history of osteoporosis
- Adults 19–50 years: 1,000 mg per day
- Women over 50 and Men over 70: 1,200 mg per day
- Pregnant or Breastfeeding Women: 1,000–1,300 mg per day
- Upper Safe Limit: Most adults should not exceed 2,500 mg per day from all sources (food + supplements)
- Check the Type of Calcium: Calcium citrate is generally better absorbed (even on an empty stomach), while calcium carbonate is cheaper but needs to be taken with food.
- Look for Third-Party Testing: Choose products verified by USP, NSF, or ConsumerLab for purity and accurate labeling.
- Consider Added Ingredients: Formulas that include Vitamin D and magnesium provide better overall value.
- Compare Value: Calculate cost per milligram of elemental calcium rather than total tablet weight.
- Watch for Fillers: Avoid products with excessive fillers, artificial colors, or high sugar content (especially in gummies).
