Calfax Plus is a multimicronutrient bone‑health and neuro‑support formulation that combines calcium, active vitamin D, vitamin K2, methylcobalamin, magnesium, zinc, and boron in a single dosage form. It is designed to support bone mineralization, osteoporosis‑risk management, and nerve‑tissue integrity, especially in adults, elderly, post‑menopausal women, and patients on long‑term steroids or with poor dietary intake.
Key benefits
Calcium carbonate + calcitriol + vitamin K27 work together to enhance calcium absorption, promote bone‑matrix formation, and direct calcium into bone rather than soft tissues.
Methylcobalamin supports nerve‑tissue repair, myelin synthesis, and helps manage vitamin B12‑deficiency‑related neuropathy.
Magnesium, zinc, and boron act as co‑factors in bone‑matrix formation, collagen synthesis, and mineral metabolism, contributing to overall skeletal and musculoskeletal health.
Typical use and precautions
Usual dose is commonly 1 capsule/tablet once daily, preferably with food, as per local prescribing or OTC‑labelling guidance; exact strength‑wise regimen should follow local regulatory inserts.
Avoid or use cautiously in patients with hypercalcaemia, hypercalciuria, renal stones, severe renal impairment, sarcoidosis, or concomitant high‑dose vitamin D therapy, and monitor serum calcium, phosphate, and renal function in prolonged use.
Astemax positions Calfax Plus as a FSSAI‑approved, WHO‑GMP‑compliant supplement, suitable for physicians and pharmacists recommending a comprehensive bone‑plus‑nerve‑health combination in community and hospital‑based practice.
