Poop has a metallic smell. Normal size and consistency, light brown color. I take omeprazole 2 bid. And eat a serving of all bran every morning.?

Seems normal. I don't think the smell of your stool necessarily means pathology. The heavy fiber diet leads to softer,lighter colored stools but you don't have any true bowel symptoms. If you have continuing concerns, consult your physician or a gastroenterologist.
