What are the side effects of B complex vitamins?

Dear Doctor,
Right now I'm taking Neurobion (B complex vitamins) as instructed by chiropractor to heal my lower back pain. At the moment also my hair also thinning and some friends suggested me to take Biotin. As per my reading, Biotin also comprised of B complex vitamin. Is it harmful to combine these to supplement together? I'm afraid if it too much of vitamins will cause side effect

Thanks for writing to HCM

Biotin, known as vitamin B7 is considered as part of b complex.
both can be combindly taken
Being water soluble vitamins, Vitamin B complex is not stored inside the cells; rather they are excreted in the urine. Because of this, the risk for over dosage is not likely. However, when normal individuals do not need high amounts of vitamin B exceeding the tolerable limit, they are usually at risk for developing over dosage. Over dosage from the B vitamins causes osmosis of water from the interstitial space to the intravascular space in order to dilute the large doses and promote excretion through the urine. Symptoms of Vitamin B over dosage include:

Increased thirst
Flushing of the skin
Excessive urination
These symptoms are the compensatory mechanism of the body to eliminate the excessive vitamins through the bladder and bowels.
Discuss this with your doctor and then decide
Hope this helps
