Biotin: an essential vitamin for healthy hair
Biotin: A versatile super vitamin
Vitamin B8 plays a crucial role in many metabolic processes, including hair health:
- Helps macronutrient metabolism: Biotin enables carbohydrates, lipids and proteins to be converted into energy.
- Promotes healthy skin, hair and nails: it contributes to the production of keratin, the major protein in hair, skin and nails.
- Necessary for the functioning of the nervous system: vitamin b8 is involved in the production of myelin, a protective sheath surrounding the nerves.
- Essential for regulating blood sugar levels: Finally, biotin helps regulate blood sugar levels.
How does biotin work?
Biotin acts as a coenzyme in a number of important enzymatic reactions. It binds to specific enzymes and helps them to function properly. Its main actions include :
- Biosynthesis of fatty acids Essential for creating the basic components of cell membranes.
- Gluconeogenesis Glucose: Allows the production of glucose from non-carbohydrate compounds, crucial for maintaining energy levels.
- Amino acid metabolism Helps break down certain amino acids, including leucine.
- Cholesterol metabolism Plays a role in managing cholesterol levels.
The benefits of biotin supplementation
Taking biotin supplements offers several potential health benefits, including:
- Improved hair and nail health: the vitamin strengthens fragile, brittle or thin hair and nails.
- Improved skin condition: Biotin helps reduce acne and eczema.
- Regulation of blood sugar levels: vitamin b8 improves glycaemic control in people with diabetes.
Signs and symptoms of biotin deficiency
Although a vitamin B8 deficiency is rare, it can lead to a number of health problems. Here are a few signs and symptoms that may indicate a deficiency:
Signs on the hair and nails:
- Fine, brittle or fragile hair: Vitamin H is essential for the production of keratin, the protein responsible for the strength and structure of hair.
- Hair loss: Significant and unusual hair loss is potentially a sign of biotin deficiency, especially if accompanied by other symptoms. However, there are other causes of hair loss, see here
- Fragile, brittle or cracked nails: Vitamin B8 is also important for nail health. A deficiency of this vitamin will make nails brittle, fragile and soft, and more likely to crack or split.
Sign on the skin:
- Seborrhoeic dermatitis: An inflammation of the skin characterised by red, oily patches, often accompanied by dandruff and itching. Biotin deficiency aggravates this condition.
- Dry, flaky skin: Vitamin H helps to keep the skin hydrated. A deficiency is potentially the cause of dry, flaky and irritated skin.
Other symptoms:
- Fatigue and weakness: Vitamin B7 or B8 is involved in energy production. Chronic fatigue and muscle weakness are likely to indicate a deficiency.
Treatment of biotin deficiency:
Treatment of vitamin B8 deficiency generally involves taking biotin supplements. The recommended dose for adults is 30 micrograms per day. Most people respond quickly to supplementation and symptoms disappear within a few weeks or months.
Dietary sources of biotin
To prevent vitamin B8 deficiency, a balanced diet is key. Here are some biotin-rich foods to include in your summer diet:
- Egg yolks An egg yolk contains around 5 microgrammes of vitamin B8.
- Liver Beef and chicken liver are also rich in biotin.
- Nuts and seeds Almonds, walnuts, sunflower seeds and chia seeds are packed with vitamin B8.
- Green vegetables Spinach, broccoli and cauliflower are excellent options.
- Mushrooms : White and portobello mushrooms are good sources.
Biotin supplementation
It is generally available in the form of food supplements, including tablets, capsules and softgels. The recommended dose for adults is 30 micrograms per day. For example Biotine the Mossi
The advantage of supplementation is that it is very well tolerated and is not associated with side effects on the body. Provided that the daily doses are respected. We recommend taking biotin for people looking to strengthen their hair and nails, or to combat hair loss. It is a supplement that goes well with a hair transplant for example. As a complement to biotin, we recommend vitamin shampoos designed to help boost hair effectively. For example, shampoos such as Growth-factor
