Help my Ma get rid of the metallic taste

Hi guys

I remember reading or hearing Chad talk about a metallic taste in this mouth but I can’t remember what he thought the cause was lack of protein or something else, my Ma is now having the issue and I want to give her some advice


Is she having this issue while riding at high intensities or just during normal life? Because during high intensity riding it can be normal but you shouldn’t be having that taste just walking around.

I don’t exactly remember what the cause was during exercise. But if it’s during normal stuff then I would see a doctor about it.

Edit: I think that metallic taste during exercise can come from the rupturing of red blood cells as they get shoved through your vessels at high HR and BP.
