Brittle nails can be weak, thin, nails that peel or break easily, and/or grow slowly.
The common condition of brittle nails is often not definitively linked with any known cause. Nonetheless, natural medicine may be able to help strengthen brittle nails.
Most conditions that affect nails are unrelated to nutrition; they are caused by a lack of oxygen associated with lung conditions, haemorrhage due to infection, or inflammation around the nail due to infection. If there is any question about what the problem is, it is important to get a diagnosis from a healthcare practitioner.
What are the symptoms of brittle nails?
People with brittle nails may have frequent or easy breaking, cracking, splitting, or tearing of their nails.
Nutritional supplements that may be helpful.
Nutrition can affect the health of nails in a variety of ways. Iron deficiency may cause spoon-shaped nails. For years, some doctors have believed zinc deficiency causes white spots to appear on nails. In China, excessive selenium has been linked to nails actually falling out.
Biotin, a B vitamin, is known to strengthen hooves in animals. As a result, Swiss researchers investigated the use of biotin in strengthening brittle fingernails in humans, despite the fact that it remains unclear exactly how biotin affects nail structure.
An uncontrolled trial of 2.5 mg biotin per day found improved firmness and hardness in almost all cases after an average treatment time of 5.5 months. In a controlled trial using 2.5 mg of biotin per day, women with brittle nails, who had their nail thickness measured before and at six to fifteen months after, found their nail thickness increased by 25%.
As a result, splitting of nails was reduced. In an uncontrolled study of people who had been taking biotin for brittle nails in America, 63% showed improvement from taking biotin. Although the amount of research on the subject is quite limited and positive effects do not appear in all people, those people having brittle nails may want to consider a trial period of at least several months, using 2.5 mg per day of biotin.
Gelatine has been marketed as a remedy for brittle nails since the turn of the twentieth century and has been mentioned in medical journals at least since the 1950s. Gelatine is a slaughterhouse by-product, made from the hooves and other inedible connective tissue of cows. While some people claim success using gelatine to strengthen brittle nails, others claim that the remedy is ineffective, and that the real cause of brittle nails is lack of moisture, not protein deficiency.
One doctor has observed that supplementation with glucosamine sulphate (amount not specified) can increase the growth rate and strength of fingernails and toenails; however, no controlled trials have been done.
Herbs that may be helpful.
Anecdotal reports suggest that horsetail may be of some use in the treatment of brittle nails. This may be due to the high content of silicic acid and silicates in horsetail, which provide approximately 2 to 3% elemental silicon.
