Do vitamins b, c and magnesium cause yellowish brown stool and bright yellow urine?

Do vitamins b, c and magnesium cause yellowish brown stool and bright yellow urine?

Riboflavin: I don't know about the stool color, but b-vitamins are often spiked with a large amount of riboflavin / vitamin b2. This has a natural yellow fluorescence and its changing the color of the urine perhaps also makes people think the vitamins are better. It's harmless. ...Read more

What would cause my urine to be bright yellow, and smell really salty?

What would cause my urine to be bright yellow, and smell really salty?

Probably several: But, one easy thing to try is to drink lots of water (8+ 8oz glasses per day) for a day or two. If this clears it - you might not have a problem other than being dehydrated. But, if it is still not right - see your doctor for an exam and lab work. Being pregnant makes it even more important to be checked and your body may be a sensitive one too. If water isn't enough, see the doctor. Best wishes! ...Read more

My urine is bright yellow but i don't take vitamins, cause?

Urine Color: The color of your urine can be changed by dyes in foods, medications, drinks, disease and by ingesting dyes. If you changed the brand of BCP or the generic version it could cause this. The urinary tract medicine pyridium is a common cause as well. Liver disease can cause this as well. If you have any yellowing of the whites of your eyes or this does not resolve seek medical care ...Read more
