multi vitamin causing bright yellow pee

[DJFL77I]

I know if you have too much vitamin B your urine will turn bright yellow from your body expelling it.... 

so does this mean I have too much or don't need to take extra?

Bright yellow urine is a sign of excess B-vitamins in the body, including B-2 and B-12, although this condition is harmless.

You are correct it is the b vitamin riboflavin. Riboflavin (vitamin B2) contains a yellow-green pigment that can enhance the color of your urine.

The supplement you are taking should be formulated with riboflavin  RDA values at acceptable levels. If you take the amount suggested on the product you won't overdose supplementally on riboflavin.

Your body won't be able to absorb 100% of the vitamin supplements you take at any one time.  The unabsorbed vitamins are excreted in urine, but that doesn't mean you don't still need it.  Your body is absorbing part of it.  Continue to take the vitamins.  

Are you taking your vitamins with meals or on an empty stomach?  Vitamins are better absorbed if taken with meals.  Taking supplements with meals helps with absorption because the transit time (time spent in the digestive tract) is longer.  Vitamin supplements taken with meals help absorption of other nutrients in the food eaten.

Are you keeping a food journal?  You may want to add notations about when you take your vitamins and when you notice the bright yellow pee.  

For those aficionados of crime scene tv shows...

Riboflavin in both blood and urine will glow in the dark under black light!  

It's not quite Halloween, but let's have some fun!  Make your own glow in the dark candy!
