B-complex vitamins again?

Question

what kind of effect does B-complex vitamins have on the body? my urine is a really funny color, like a neon yellow...like glow in the dark type of yellow. any reasons why?

Answer 1

The B vitamins do seem to do that, maybe it is a dye in the pills. Do watch out for niacin however, it can cause flushing of the skin and feeling flushed even though the body temp was 96. It is given for cholesterol control and has a reaction that sent my mate to the hospital.

Answer 2

B vitamins are water-soluble. This means that once the cells of your body have absorbed what they need, the excess vitamins are excreted in your urine. This is what gives it the strong yellow color.

Because excess B vitamins are excreted, there isn't much of a health risk of taking such large doses. You are wasting money, however, because you would be providing sufficient vitamins with a much lower dose.

Please be aware that there is significant danger of poisoning when large doses of fat-soluble vitamins, like E or A, are taken. It is dangerous to exceed the RDA for these vitamins.

Answer 3

The neon yellow is caused by Riboflavin (B2).

Regarding the person that believes you do not need high doses of B-vitamins: apparently he is not familiar with biochemical individuality. There are hundreds of variations in the genes that code for the enzymes that require various B-vitamins as cofactors to activate the enzyme's function. Many of these genetic variants require much higher doses of the B-vitamin cofactor to work optimally. In fact, over 50 'GENETIC DISEASES' have been identified that can be effectively treated with mega-doses of the appropriate B-vitamin cofactor . Hyperhomocystinuria is one example (it requires very high doses of B6 to activate the genetically defective enzyme).

A common gene variant present in up to 40% of the U.S. population is the MTHFR (methylene tetrahydrofolate reductase) 677 C to T gene that codes for an enzyme critical to proper functioning of the folate cycle and the methionine cycle. People with this variant (homozygotes) require much higher doses of folic acid (a B-vitamin) and/or B2 to get the enzyme to work adequately. If you have low intakes of these vitamins (very common) and the genetic variant, you are at increased risk for many serious diseases including cardiovascular disease, stroke, some cancers, osteoporosis, Alzheimer's and depression.

B-vitamins are very important nutrients. Many people have much higher requirements than the RDAs for these vitamins.

Best wishes and good luck.
