Is this calcium and multivitamin capsule safe to take?

This soft gelatin capsule combines calcium with active vitamin D, omega-3 fatty acids, folic acid, and B12, and for most healthy adults that combination is well tolerated when taken as directed. That said, calcium and vitamin D supplements aren't entirely risk-free if you already get enough through diet or have certain kidney or heart conditions, so more isn't automatically better. It's a good idea to mention it to your doctor, especially if you're already on other supplements, just so the doses don't stack up unnecessarily.
