Biotin supplements are currently one of the most popular means of improving hair and nails. Biotin is considered a real miracle in hair conditioning. But do we really need to take biotin? What side effects can it cause?
The undeniable popularity of biotin
Biotin has great PR. It leads the way in pharmacies and in the advertising of dietary supplements. If someone goes to a pharmacy for “something for their hair”, they will almost certainly be offered a preparation containing this substance. However, there are rumours that although biotin has a positive effect on hair, it can have a negative impact on the functioning of other areas. Biotin supplementation – when is it really worth to take and how to do it with your head?
Biotin for hair loss – always?
Biotin is one of the B vitamins. We can also find it under the names of Vitamin B7 and vitamin H. Biotin deficiency can adversely affect the condition of hair and nails. We can observe excessive hair loss, splitting of the nails and deterioration of the skin. In practice, however, vitamin B7 deficiencies occur in exceptional cases.
It is available in many food products, and moreover, the body produces it itself through the intestinal bacterial flora. Biotin deficiency can be suffered, for example, by people on a restrictive weight loss diet who do not provide themselves with many other vitamins and minerals Biotin deficiency can usually be compensated for by changing diet and eating habits. Supplementation also Improves hair condition.
Usually a monthly treatment with biotin gives visible results. However, it does not eliminate the problem of other deficiencies. Before starting the supplementation you should also consider other potential causes of hair condition deterioration. These may also include hormonal problems or dysfunction of the scalp. Sometimes, thinning of hair results from seasonal changes, general weakness of hair condition (lack of moisture, weak bulbs) or occurs after giving birth.
Biotin supplementation – when and on what terms
A break in the intake of biotin is indicated before the immunological blood test, because an increased amount of this substance may disturb the result. The same applies to hormone blood tests. Biotin may overestimate the actual values of peripheral hormones and on the other hand lower the actual TSH value. As a result of the tests, we may find that we have hyperthyroidism when this organ functions properly.
If we want to supplement biotin, we need to look at its content in selected preparations. We should also remember that multicomponent supplements, e.g. those containing field horsetail, usually already have a certain dose of biotin in them. If you take them, it is probably not advisable to buy another supplement with biotin.
Can you overdose biotin?
This question is worth asking, because in most dietary supplements with biotin, its content definitely exceeds the recommended daily dose. While we should only supply ourselves with 30-35 micrograms of biotin per day, we often have as many as 5000 or even 10000 micrograms in a single dose of the supplement! Although the body copes well with excess biotin, it is removed with urine.
This, however, only applies to completely healthy people whose kidneys and urinary tract function flawlessly and the supplement does not come into contact with other drugs. We certainly should not take biotin without a doctor’s recommendation if we are treating a disease.
