It looks like you're asking about the availability of the Calsmart tablet containing magnesium hydroxide, vitamin D3, calcium citrate, and zinc sulphate. Unfortunately, I don't have access to real-time stock or purchase information for specific medications.
For the most accurate and up-to-date information on when Calsmart tablets will be available for purchase, I recommend contacting a local pharmacy or the manufacturer directly. Additionally, consulting with a doctor or pharmacist can help you find suitable alternatives if needed.
If you are considering this supplement for bone health or related concerns, a consultation with an endocrinologist or a general physician would be beneficial to ensure it fits your health needs.
