Although researchers have not yet been able to provide any concrete proof about side effects of biotin, it is being assumed that this vitamin has some minor side effects.
Another test was conducted on a pregnant rat wherein it was given high doses of Vitamin B7. Later, it was observed that the placenta of the fetal rats decreased in size which, automatically, increased the probability of miscarriage.
In one case, it was noticed that high intake of vitamin B7 and vitamin B5 lead to a life-threatening condition called eosinophilic pleuropericardial effusion. It was assumed that, consuming both vitamins together leads to this condition.
Although, it's a very beneficial vitamin, intake of biotin should also be kept in check. Basically anything that is taken in excess is bound to affect your body in some way or the other. A daily adequate intake (AI) of biotin, for different age groups, is recommended by U.S. Food and Nutrition Board of the National Academy of Science's Institute of Medicine. Especially during biotin deficiency the intake should be strictly under medical supervision.
Biotin, also known as Vitamin H or B7, is a water soluble B-complex vitamin, which is necessary for cell growth and production of fatty acids in living organisms. The word biotin is derived from Greek word ‘bios' meaning life. A research, in 1940s, revealed that biotin supplement helped in strengthening the hooves of horses and pigs.
