A biotin overdose is a very rare occurrence. In general, it probably won’t ever happen. Biotin is a B-vitamin, sometimes called Vitamin H. It dissolves easily in liquid. Therefore, any excess amounts of biotin that are taken orally will most likely be passed through the body quickly and excreted through the urine.
There most likely will not be any side effects if a slight accidental overdose occurs. It is far more likely that one would experience side effects from a biotin deficiency than from a biotin overdose. Even though it is very rare, it is possible to overdose on biotin.
If any side effects arise from a biotin overdose, they will probably be seen in someone who has been taking excess doses of the vitamin for a long period of time. The skin may break out with a rash, blood sugar levels may increase, and insulin release may slow. These are all symptoms of a biotin overdose. There is a lot of research still going on to see what might be the effects of a biotin overdose.
Biotin occurs naturally in foods such as certain legumes, eggs and other dairy products. As long as a healthy well-rounded diet is consumed it is very unlikely that you would need supplemental biotin. Make sure to include plenty of egg yolks, meat, and leafy green vegetables in your diet.
Another source of biotin is by taking a daily vitamin. A small dosage of biotin is generally available in over the counter vitamins. Check the label to be certain, especially if you are concerned about a biotin overdose or deficiency.
Biotin has been prescribed by a physician in cases of hair loss and for various problems with the eyes, skin or nails. Supplemental biotin is taken for brittle nails, loss of appetite, dermatitis, and also for lethargy and hallucinations. These are all signs of a biotin deficiency. It is also given to pregnant women to avoid pregnancy related deficiencies.
If you choose to take biotin for things such as a low metabolism or hair loss be sure to follow the dosage on the package. To avoid a biotin overdose, do not take the supplement for a long period of time. It is best to see a doctor before beginning any regular biotin supplemental program.
If you suspect that you have take a biotin overdose stop taking it immediately and consult your preferred health professional.
