I recommended to a friend that she take your vitamins. After a week, she says she is feeling better, but has extremely yellow urine. Is that an overabundance of B vitamins being excreted, or could the vitamins be starting to eliminate other toxins or harmful substances from the body which are yellow in color?
Riboflavin, or vitamin B2, is the vitamin that imparts the fluorescent yellow to urine. This means the body does not need the amount of B2 that is in the multivitamin and is excreting it out in the urine. I have colleagues that have called this expensive urine. The challenge we all have is to know exactly how much our individual body needs of each of the vitamins in all circumstances and in all times. That information is not available. If we overload our system with co-factors and nutrients needed for metabolism and proper functioning of the body, the body will have total access to it and use what it needs. If we chronically deprive our body of the nutrients, the cells become sluggish, find alternative pathways, albeit inefficient, to accomplish the needs of the cells.
If a person drinks too much water, the kidneys are designed to get rid of the excess. If we drink too little water, the body gets dehydrated, and does not function optimally. This could place a stress on the kidneys and the whole body. From my mind, better to place abundant nutrients in the body, let the body take what it needs, and release the rest. It may take weeks or months for depleted cells to be able to absorb the full complement of nutrients it needs because of the faulty transmission at the cell membrane level from depleted nutrients.
As the body gets healthy, and the detoxification systems start to function better, there may be noticed various smells in the urine as toxins are released. This typically takes weeks or months for these major changes to take place in the body.



My doctor says I can get all the vitamins and minerals I need from my food. What is your opinion on this?
I used to say the same thing to my patients, back in the days before I studied healthy alternatives. It is the party line of allopathic medicine, although that is starting to change. Here's the bottom line, and I'll follow up with some info on what allopaths are now doing:

I have often wondered about yellow urine, too, after taking a multiple vitamin. I tend to both agree and disagree with Dr. Gardner. If the urine is yellow, it is a sign that the riboflavin in the vitamin is of the synthetic variety. Riboflavin from food does not appear as yellow urine. Furthermore, the yellow urine is not only an excretion, but such an excretion places additional stress on the liver and kidneys to get rid of it. Please tell me that I am wrong!

does the extreme excretion of riboflavin that turns urine dark yellow also cause a false positive result on a drug of abuse screen for THC? I have to take screens once a month and have noticed that when I take my megavitamin sup-plement which contains 30mg riboflavin, my screen is positive for THC, even though a follow-up gc/ms analysis is completely negative for any drugs.
