if their meds contain animal products

Some patients are asking if their meds contain animal products.

Keep the biggies in mind. Desiccated thyroid comes from pig thyroids...heparin from pig intestines...pancreatic enzymes from pig pancreases...Premarin from pregnant mares' urine...and some vaccines (influenza, MMR, etc) are grown in eggs.

Glucosamine is usually from shellfish...chondroitin from cartilage...vitamin D3 from lanolin...and heme iron (Proferrin) from animal blood. Omega-3 fatty acids are often from fish oil...and calcium can come from oyster shells or animal bones.
