This article highlights the importance of calcium for maintaining bone and overall health, discusses recommended daily intake at different ages, and reviews top calcium supplements like Solgar, Rainbow Light, and Citracal, emphasizing their benefits in preventing deficiency-related health issues.

Key Calcium Supplements to Prevent Deficiency

Calcium plays an essential role in maintaining healthy teeth and bones, supporting muscle function, regulating blood vessels, transmitting nerve signals, and balancing hormones. The majority of calcium in our body is stored in bones and teeth for strength, with about 1% roaming in the blood and bodily fluids to facilitate metabolic functions.

According to the Institute of Medicine, recommended daily calcium intake varies by age:

200 mg for infants under 6 months,

260 mg for infants 7-12 months,

700 mg for children 1-3 years,

1000 mg for ages 4-8,

1300 mg for 9-13 years,

1000 mg for adults,

1200 mg for women over 50.

Calcium deficiency arises when intake is insufficient over time, often worsened by low vitamin D, phosphorus, or magnesium levels—all crucial for calcium absorption. Signs include fatigue, muscle cramps, dry skin, brittle nails, delayed puberty, cavities, fractures, and sleep issues.

Untreated calcium deficiency can cause serious health problems such as osteoporosis, cardiovascular issues, hypertension, and increased cancer risk. Therefore, supplementation is vital. Main supplement forms include calcium carbonate and calcium citrate. Here are some popular options available locally:
