A member asked:

Ive been taking vit b tablets and have noticed that my urine is bright yellow, will this effect the results if i were to take a pregnancy test?

A doctor has provided 1 answer

No: These manufacturers spike their pills with huge amounts of riboflavin, which is harmless and makes the urine a spectacular yellow so people will think the pills are very powerful.
