Overdosing on vitamins does exist. Unpleasant situations occur when people start taking them without a doctor's prescription. Vitamin B group is involved in tissue respiration, energy production, and plays a significant role in maintaining both mental and emotional health. It's impossible to accumulate excessive amounts of them in the body.

RBC-Ukraine reports on how vitamin B overdosing looks, according to a video by neurologist and psychotherapist Hanna Cherednychenko on Instagram.

Overdosing on vitamins does indeed exist. The bitter truth is that the body only absorbs as much as it can. The excess will simply be excreted through urine.

But the worst part isn't just flushing your money down the toilet; it's when you start increasing the dose of a vitamin, unpleasant signs of overdose may occur.

"Vitamin B6 - pyridoxine, is unique. Its symptoms of deficiency and overdose are identical," emphasized the doctor.
