Calcium

Individuals who might benefit from testing their calcium levels include postmenopausal women, people with kidney disorders or thyroid issues, and those on medications that affect calcium absorption. Testing is also helpful for individuals experiencing symptoms of high or low calcium, such as muscle cramps or weakness, to ensure proper bone health and metabolic function.

Symptoms of low calcium include:

• Muscle cramps and spasms
• Numbness and tingling in fingers
• Fatigue and lethargy
• Dry, itchy skin
• Brittle nails
• Tooth decay
• Weak or brittle bones
• Confusion or memory loss

Foods rich in calcium include dairy products like milk, cheese, and yogurt. Leafy greens such as kale and broccoli, and fortified foods like cereals and plant-based milks, also offer good amounts. Fish with edible bones, like sardines and salmon, are great sources. Plant-based options like tofu, almonds, and white beans are also high in calcium, providing a variety of choices for different diets.

Calcium supplementation is beneficial for supporting bone health, particularly in individuals at risk of osteoporosis, such as postmenopausal women and older adults. It aids in maintaining bone density and strength, reducing the risk of fractures. Additionally, calcium plays a vital role in muscle function, nerve signaling, and blood clotting. For those who may not get enough calcium through diet, such as people with lactose intolerance or certain dietary restrictions, supplementation can help meet their calcium needs.
