Propecia and Bone Health: Potential Effects on Density & Mineral Absorption

Question
Are there any hints that propecia can cause bone density loss or impede the absorption of calcium or magnesium?

Answer
Yes, it appears to have a very mild effect on all these due to its estrogenizing effect but no reports are available showing this to be significant. If a person were to take a standard dose of calcium with vit D, and magnesium oxide twice daily the effect is generally offset. OK?
