Ostelin Vitamin D3 1000IU

Ostelin is a well-known Australian brand specializing in Vitamin D and calcium supplements. It was originally established in Australia and has grown to become the country's leading Vitamin D brand. The products are widely recognized for their role in bone health and immune support, particularly within the Australian market where they are frequently recommended by healthcare professionals.

Historically, the brand was owned by the French pharmaceutical giant Sanofi. However, in recent years, the ownership transitioned as Sanofi sought to divest parts of its consumer healthcare portfolio. As of 2024 and moving into 2026, the brand is managed under the umbrella of a dedicated consumer healthcare entity. While the brand has deep Australian roots and the majority of its manufacturing for the local market remains in Australia, the ultimate corporate oversight is conducted through a global network focused on consumer health and wellness.
