Vitamin smell in urine

Hoping someone can help and tell me if this is normal.
I am about 3 1/2 months out from RNY and my urine smells like my multivitamin.  The urine is very yellow in colour and really has a strong smell.
The multi that I am taking is the GNC Women's Ultra Meg (a large green tablet).  I also take calcium citrate from GNC.
I have read that smelly urine can indicate dehydration but I really don't think that is the issue.  I take in over 2 litres of water every day.
Any help, guidance or advice would be appreciated.

I have not had surgery yet, but I have been taking vitamins for over a year now and my urine does smell of vitamin and yellow. It is normal. I freaked at first but Doctor was not concerned at all.

Your taking in plenty of fluids. I'd say it is the vitamins and not to worry.

It's normal.

The bright yellow is probably riboflavin.  It also stinks.

Usually this urine color and odor happens within a couple of hours of taking your vitamins. I doubt it happens every time you go. Very dark urine indicates you're dehydrated.  You should probasbly take a daily dry D3 too , a minimum of 5K IU, probably more.  Standard D2 is not absorbed well. Unless the bottle specifically say D3, and only says vitamin D, it's almost a 100
% guarantee it's D2, not absorbed nearly as well as D3. D3 is also available in the less expensive formn of a softgel--you don't want that one cause the D3 is suspended in oil. You need a dry d3 capsule or pills.  Unless you're taking D3, your labs will most likely indicate very low d levels or show that you are below normal.  Good D levels are needed to help you absorb your caclium citrate properly.
