Biotin is known for its role in tissue health and its major contribution to maintaining beautiful skin, shiny hair, and strong nails. Why and how can you make the most of this vitamin for your beauty? We tell you everything.

The great trend of dietary supplements is in full swing, and in this general euphoria, it is not uncommon to see or hear names and words that we do not understand very well... such as the term Biotin, for example. This word often appears on the packaging of dietary supplements, but also on cosmetic products aimed at maintaining hair, nails, and sometimes skin. But do we really understand it? We examine the term and its benefits in detail. 

What exactly is biotin? 

If we look at etymology, the word biotin contains the prefix bio, a derivative of the word biotos which means life in Greek. The tone is thus set! It is important to know that biotin is a water-soluble vitamin, meaning that the body does not store it or produce it in sufficient quantities, so a regular external supply is required. It is part of the B vitamin group and is also known as vitamin H or vitamin B8. It plays an important role in the proper functioning of our body because it has the power to act at the cellular nucleus level to regulate gene activity...

Basically, it helps the body convert the foods we consume into nutrients and energy, two essential players for a healthy life. In addition, it also regulates blood sugar levels, ensures the proper functioning of the nervous system, prevents skin rashes (for beautiful skin), promises strong nails, stimulates hair regrowth while promoting their growth and blocking hair loss, for a healthy mane. As you may have guessed, biotin (vitamin B8) is essential in many ways; you can trust it to take care of our health and beauty. 

What are the benefits of biotin for our hair? 

Biotin is widely recommended for hair care. Why? It's simple: by allowing the body to absorb the right nutrients, it promotes the health of the hair fiber! Specifically, with a sufficient supply of biotin, you are sure to have shiny, strong, supple hair that grows quickly and is less prone to falling out. You may not know it, but biotin or vitamin B8 is found quite a bit in our diet. We therefore consume it regularly without even realizing it! To keep beautiful hair, remember to include these biotin-rich foods in your diet. 

Foods of plant or animal origin that contain biotin: 

• Dry yeast
• Liver
• Kidney
• Egg yolk 
• Mushrooms
• Beans 
• Lentils 
• Salmon
• Banana 
• Sweet potato, oats, almonds... 

Generally, a balanced diet allows the body to absorb enough, but it is not forbidden to supplement this intake with dietary supplements or by using cosmetic products that contain it. 

Vitamin H or B8 is also excellent for taking care of brittle nails and making them stronger! It is also recommended for beautiful skin since it prevents blemishes. In these cases, taking a dietary supplement can be accompanied by a beauty routine including biotin-based products! 

How much biotin can we really take? 

When talking about quantity and biotin, the figures are not really established. We talk very little about biotin deficiency in adults, since we easily find it in our general diet (see the list of foods that contain it above). However, if we look for exactly how to quantify it, the Institute for Research on Wellness, Medicine and Sports recommends an intake of 50 to 60 micrograms per day for adults and the elderly.

If you choose to take biotin in the form of a course of dietary supplements (in the form of a capsule, powder, or gummies), then you just need to follow the dosage indicated on the box, but above all read the instructions carefully. Know that some courses of dietary supplements require an adjustment in lifestyle. Regarding the aesthetic aspect via cosmetic products, since biotin is not ingested, a morning and evening use may be sufficient. 

Can biotin be combined with other nutrients for hair health? 

For even more effectiveness, biotin can be combined with various other nutrients. Especially when you decide to take it for the benefit of our hair. You can thus easily combine taking biotin with taking silica (bamboo extract) which protects among other things from oxidative stress, marine collagen, vitamin D which stimulates the hair follicle, zinc (essential for strengthening the hair fiber), selenium or even vitamin C. It is not uncommon to find dietary supplements that include most of these nutrients in the same formula. 

Biotin in cosmetic products

Although it is widely represented in the composition of dietary supplements, Biotin is also very present in cosmetic products (serums, shampoos, masks...) and that is all the better. At ROSEGOLD, for example, vitamin H is used in the eyelash beauty serum but also in the ROSEHAIR serum which takes care of the scalp and boosts hair growth.

The presence of this vitamin in the natural formula of these products allows the body to absorb the other active ingredients present in its composition. Biotin also boosts the hair growth and regrowth effect that characterizes the two serums. This allows for a proven result from the first month of use! For lasting effects, it is recommended to use these serums as a course, up to six months, morning and evening.

Biotin and contraindications, what should we know?

If you choose biotin intake in the form of a course of dietary supplements, you should know that this requires some adjustments. Indeed, biotin is not absorbed if the body consumes alcohol, for example! It is also good to take into account the possibility of suffering from side effects, as with everything, before starting a course (external or internal), check that you do not suffer from any allergies! Nothing really proves that taking Biotin in large quantities is dangerous for health, but it is always better to follow the indicated dosages and stay alert when starting a new course.
