Fluorine

What is Fluorine?

It is a non-metallic element that is toxic when it occurs in the form of a gas.

Why is it needed?

It is not essential for human life, but it is beneficial as it maintains bones and tooth enamel. In areas where the fluorine levels in drinking water are low there are higher incidents of tooth decay. The fluorine makes its way into the tooth enamel and prevents decay in children and adults.

Many are concerned about long-term problems associated with fluorine as sodium fluoride enables the body to uptake greater amounts of aluminium.

Aluminium has been linked with Alzheimer's Disease.

Some also believe that there is link between cancer and fluorine.

Where is it found?

It is found in black tea and seafood.

What happens if you are deficient?

Deficiency can occur in those who are taking zinc supplements for long periods of time, say over 12 months. Babies who are severely malnourished suffer from copper deficiency.

What conditions has it been used to treat?

Primary: 
There have been trials using fluorine in the treatment osteoporosis, yet it is thought that the new bone growth is too brittle to support weight.
 
Secondary: 
Muscle calcification

How much is normally taken?

There is no RDA.

Are there any contraindications or side effects?  

If you take fluorine at a level that is toxic them nerve damage can result.

Other problems include:

Abnormal hardening of the bones, weakness and stiffness.
