Shelcal tablet is an over-the-counter (OTC) supplement that supports bone health and helps manage calcium deficiency. It contains calcium and vitamin D3 (cholecalciferol), which together help maintain strong bones and teeth. Vitamin D3 helps improve calcium absorption and ensure proper calcium utilization in the body.

Shelcal tablets also support muscle contraction, nerve signaling, and heart function. They help improve bone mineral density and are useful in conditions like osteoporosis, osteopenia, and calcium deficiency. With regular intake, shelcal tablets help maintain calcium balance in the body, thereby lowering the risk of osteoporosis and bone fractures. It is particularly useful during periods of increased calcium requirements, such as growing years, postmenopause, pregnancy (if prescribed), and recovery from fractures or bone disorders.

The usual adult dosage is 1 tablet twice daily. It is best taken after meals to optimize absorption and help prevent an upset stomach. Follow your doctor’s advice for accurate dosage. Do not take it with other calcium supplements unless your doctor advises you to.

If you miss a dose, take it as soon as you remember. However, if it is close to your next dose, skip the missed dose and continue with your regular schedule. Do not double the dose.

Shelcal tablet is generally well-tolerated. However, mild side effects such as constipation, bloating, nausea, or stomach discomfort may occur. These effects are usually temporary. If they persist, consult your doctor.

Store the Shelcal tablet in a cool, dry place. Do not use this if you are allergic to any of its active components or its excipients. Let your doctor know about any other medications you may be taking. Shelcal tablet is not meant to be taken as a substitute for a balanced diet.
