It is a side effect.
The bright yellow color of urine after taking a multivitamin is harmless. It is caused by the excretion of excess vitamin B12. The water soluble vitamins are excreted through the urine when more is consumed than the body can use.
Bright yellow urine is typically due to high levels of riboflavin (vitamin B2), which can occur after taking multivitamins or B-complex supplements. It can also be a sign of dehydration, where concentrated urine appears darker. However, if the bright color persists without dietary changes or hydration issues, it may be worth consulting a healthcare professional to rule out any underlying conditions.
The B2 (riboflavin) is what makes pee yellow. Since B vitamins are not stored in the body (water soluble) any extra is lost in your urine. The bright yellow would happen to anybody taking the same vitamins.
Yellow is from protien. Bright yellow is OK. Dark yellow means you need to drink more water. Unless you feel bad somehow you sound OK to me. -------------------- If you are taking any vitamins or some medications, it can make your urine bright yellow.
Both cyanocobalamin (a form of vitamin B12) and vitamin B2 can cause bright yellow urine.
You need to drink more water. Aim (no irony intended) for a pale straw colour in your urine. Bright yellow is too undiluted and needs dilution by drinking more, Taking vitamin B supplements will also cause urine to be a bright yellow color - so if that is the case, no worries...
