There is a lot of research regarding biotin to prove its efficacy. Some have concluded that there is not enough evidence to claim that biotin is effective for hair growth

On the other hand, others have determined that biotin contributes to hair appearance, nail growth and skin care.

For example, biotin contributes to the keratin present in our body, improves its composition, allowing us to have beautiful and healthy hair.

In addition to this, this vitamin processes glucose from carbohydrates into energy and helps amino acids to perform normal body functions.

These are the recommended doses. But if someone thinks they need to take more biotin than recommended, it is important to see a doctor before doing so.

how do I know if I need to take more biotin?

Some people may lack biotin or have very low levels. There are certain symptoms that help us identify if this is occurring in our body. Among these symptoms are loss of body hair, weak and brittle nails, thinning hair and skin infections.

Other signs are rash around the eyes, nose, mouth and anal area. Acid concentration in blood and urine at very high levels. Nervous system disorder

In infants, it can be identified if growth retardation, slowness or weakness of the muscles are observed.

If you are showing these symptoms, do not hesitate to visit your doctor, as he/she will tell you what treatment to follow to help you recover your biotin levels.

It is also important to note that the constant consumption of raw eggs lowers biotin levels in significant ways, and without presenting symptoms.

how is Biotin used?

The easiest form of use is by oral consumption or direct application to the hair. There are several presentations of biotin, among these are the following:

  • Tablets or capsules. These are used orally, for those who may not get adequate levels naturally through their meals.
  • Shampoo or hair mask. These products help keratin to have a greater effect, allowing the hair to become silkier and shinier. In addition, it increases hair volume and prevents hair loss.

Contraindication of Biotin

This vitamin is generally quite harmless. However, some may have experienced unpleasant symptoms such as nausea, cramps, diarrhea and mild rash.

In addition, it has been shown that the consumption of supplements of this vitamin could interfere with the results of blood tests, causing alterations in the results, with high or low levels.

It is possible that biotin interacts with other medicines, such as anticonvulsants used in patients suffering from epilepsy, as these can reduce the concentration of biotin in the body.

If biotin is taken at the same time as vitamin B5, it is possible that one may affect the functioning of the other.

All of the above is evidence that before consuming any supplement containing this vitamin, it is important to consult a physician in order to avoid any adverse reactions.

Biotin is an extremely important vitamin in our body, so be sure to include it in your food. When using supplements containing biotin, remember to ask your health advisor first.
