Surprising though it may seem, our hair and nails have much in common. Both are considered to be dander – specific biological tissue characterised by high levels of keratin. This is a fibrous protein which exists in various forms including alpha keratin, the most abundant form in the human body. It consists of numerous sulphur-containing amino acids such as cysteine. Making up 95% of the hair’s composition, keratin has both a structural and protective role. For example, it helps protect the body from many external attacks including UV radiation. In addition to these essential functions, keratin may also be associated with well-being. The structural changes of this protein may affect the aesthetic aspect of the hair and nails. A breakdown in the quality of keratin may be either caused by certain diseases or associated with cellular ageing. This is why keratin-based dietary supplements have been formulated to help care for both the hair and nails. Such supplements include the new Hair & Nails Formula which has the particular feature of including a new form of keratin - Cynatine HNS®, a solubilised form for optimal bioavailability.

It’s impossible to have too much biotin

It’s important to note that taking this supplement cannot result in excessive biotin levels: being a water-soluble vitamin, any surplus biotin is directly eliminated via urine. The dose delivered by Biotin has been carefully calculated to meet your daily needs.

A lack of biotin, on the other hand, can have serious consequences. It can give rise to a series of health problems, often producing a rapid onset of troublesome symptoms.

Brittle hair and nails, conjunctivitis, mental health problems...

As we’ve seen, a deficiency in vitamin B7 can be at the root of all sorts of problems:

• Brittle hair and hair loss.
• Skin disorders (oily skin, acne, dermatitis, intertrigo) and a dull, tired, complexion.
• Inflammation of the mucous membranes, sometimes accompanied by fungal infections such as candidiasis.
• Weak, soft, and cracked nails.
• Muscle cramps, nerve damage and conjunctivitis.
• Episodes of drowsiness, mood disorders, panic attacks, and even hallucinations, nausea.
• Mental function disorders, decline in mental performance and irreversible damage to the central nervous system.
• premature death from metabolic acidosis.
• Fœtal growth delay when a pregnant woman becomes deficient, etc. (16) (17) (18) (19) (20) (21) (22)

A lack of this vitamin can be brought on by various factors:

• Impaired absorption.
• Excessive alcohol consumption, which inhibits uptake of vitamin B7.
• Excessive consumption of egg white without the yolk (egg white, especially when raw, contains avidin, a protein that prevents biotin absorption – this is even referred to as egg white injury, sometimes seen in bodybuilders who become deficient after eating too many egg whites).
• Chronic intestinal problems, as harmful bacteria in the microbiota disrupt production of vitamin B7.
• Certain genetic abnormalities that cause a deficit in biotinidase, an enzyme responsible for recycling biotin (a mutation potentially responsible for ataxia, mental delay ...).
• Epilepsy treatments (based on primidone, carbamazepine...).
• Or simply inadequate dietary intake(due to special diets, anorexia, parenteral nutrition, dietary habits ...) (23) (24) (25) (26).
