Benefits of SHELCAL 500MG TABLET

Key Benefits of Shelcal 500 for Daily Calcium Support

• Helps maintain optimal calcium levels in the body
• Supports bone strength and muscle function
• May aid in dietary calcium supplementation
• Useful for individuals with low dietary calcium intake

Shelcal 500 for Bone Health and Teeth:

Shelcal 500 is a calcium supplement enriched with vitamin D3, essential for maintaining strong bones and healthy teeth. It helps in bone mineralization, prevents weakening of teeth, and supports overall skeletal strength, reducing the risk of fractures and dental issues.

Shelcal 500 for Calcium Deficiency:

Shelcal 500 effectively replenishes calcium levels in the body, reducing the chances of hypocalcemia (low calcium levels). It supports vital functions like nerve signaling, muscle contraction, and bone density, ensuring overall well-being and reducing risks associated with calcium deficiency.

Shelcal 500 for Osteoporosis:

Shelcal 500 plays a crucial role in managing osteoporosis by improving bone density and strength. Its combination of calcium and vitamin D3 enhances calcium absorption, reducing bone loss and the risk of fractures, especially in aging individuals and postmenopausal women.

Shelcal 500 for Pregnant Women:

During pregnancy, Shelcal 500 helps meet the increased calcium demands for fetal bone development and maternal bone health. It manages calcium depletion in mothers, reducing the risk of osteoporosis later in life, and ensures proper growth of the baby’s bones and teeth.

Shelcal 500 for Postmenopausal Women:

Postmenopausal women experience a decline in estrogen levels, leading to bone loss. Shelcal 500 helps maintain bone strength, reduces the chances of osteoporosis, and reduce fracture risk by replenishing calcium and supporting better calcium absorption with vitamin D3.

Shelcal 500 for Muscle Strength:

Calcium is essential for proper muscle function, and Shelcal 500 supports muscle contraction and nerve signaling. Regular intake helps reduce muscle cramps, weakness, and spasms, promoting overall muscle health and mobility, especially in aging individuals.

Shelcal 500 for Elderly Bone Care:

Aging leads to a natural decline in bone density, increasing the risk of fractures. Shelcal 500 provides essential calcium and vitamin D3 to support bone strength, reduces the chance for osteoporosis, and promote better mobility, ensuring overall skeletal health in the elderly.

How SHELCAL 500MG TABLET Works

How does Shelcal 500 work in the body?

Shelcal 500 contains calcium carbonate and vitamin D3 (cholecalciferol), which work together to improve bone health.

Role of Calcium in the Body:

• Calcium is a vital mineral required for bone strength, muscle function, and nerve signaling. However, calcium absorption in the body depends on vitamin D3, which helps in its proper uptake from the intestine into the bloodstream.
• Shelcal 500 replenishes calcium levels, strengthens bones, corrects deficiencies, and reduces the risk of osteoporosis, fractures, and muscle weakness. It is especially beneficial for pregnant women, postmenopausal women, elderly individuals, and those with calcium deficiency.

Diet and Lifestyle Advice

How to support calcium intake naturally?

1. Add Calcium-Rich Foods to Your Diet

• Dairy products: milk, yogurt, paneer, and cheese
• Leafy greens: kale, broccoli, and amaranth
• Calcium-rich seeds: sesame seeds, chia seeds
• Fortified foods: breakfast cereals, plant-based milk (soy, almond) fortified with calcium
• Tofu and ragi (finger millet): great vegetarian options

2. Get Adequate Sunlight for Vitamin D3

• Aim for: 15–30 minutes of morning sunlight exposure on bare skin (face, arms) several times a week
• If sunlight exposure is limited, Vitamin D3-rich foods like egg yolk, fatty fish (e.g., salmon, sardines), or fortified dairy help bridge the gap

3. Maintain an Active Lifestyle

• Regular weight-bearing exercises like: Walking,  Yoga
• Resistance training support bone density and help the body utilize calcium effectively.

4. Avoid Calcium Blockers

• Limit Excessive caffeine (more than 2–3 cups/day), High sodium intake (processed foods) and Colas and sodas with phosphates
• Smoking or heavy alcohol consumption

Low intake of calcium-rich foods: Why it matters

• People with lactose intolerance who avoid dairy
• Elderly individuals with reduced appetite or absorption
• Postmenopausal women with changing nutrient needs
• Vegans/vegetarians who miss out on animal-based calcium sources
• Teens and young adults with unbalanced diets

Avoid pairing with iron tablets - Space them by 2 hours

Calcium can interfere with the absorption of iron when both are taken together. If you are using iron supplements or iron-rich medications (like ferrous sulfate or multivitamin combinations), it is best to space your calcium and iron doses by at least 2 hours.

Why it matters:

• Calcium competes with iron for absorption in the gut
• Taking them together may reduce the effectiveness of both
• Separating them improves nutrient absorption and overall benefit

Why Plant-Based Eaters Should Be Mindful of Calcium and Vitamin D3

While plant-based diets offer many health benefits, they may lack adequate calcium and vitamin D3, two nutrients that play a crucial role in supporting bone strength, muscle performance, and cellular function. Individuals who follow vegetarian or vegan diets should be particularly mindful of these nutrients, as many common sources like dairy, eggs, and fatty fish are excluded.

Limited Natural Sources

Plant-based calcium sources like leafy greens, sesame seeds, tofu, and ragi are helpful but:

• Some leafy greens (e.g., spinach) contain oxalates that reduce calcium absorption
• Vitamin D3 is not naturally present in most plant foods
• Fortified plant milks or cereals may not provide consistent daily amounts

Sunlight is not always enough

Vitamin D3 is synthesized by the skin through sun exposure, but modern indoor lifestyles, pollution, sunscreen use, and darker skin tones can reduce natural vitamin D3 production. This makes supplementation a useful option, especially for those with limited sunlight exposure.

Drug - Drug interaction

• Thiazide diuretics: May increase the risk of hypercalcemia by reducing calcium excretion.
• Corticosteroids: Reduce calcium absorption; higher doses of Shelcal may be required.
• Ion exchange resins (e.g., cholestyramine) and laxatives (e.g., paraffin oil): May decrease vitamin D absorption.
• Tetracyclines: Calcium can interfere with absorption; take Shelcal 2 hours before or 4-6 hours after.
• Bisphosphonates/Sodium fluoride: Take Shelcal 3 hours later due to reduced absorption.
