There is no good evidence of any adverse medical effects associated with the consumption of water with fluoride naturally or artificially added at a concentration of 0.5 – 1.0 mg / litre other than the increase in dental fluorosis. US studies in areas with natural fluoride levels of up to 8 mg / litre found no clinical evidence of harm. However there is clear evidence from India and China that skeletal fluorosis and an increased risk of bone fractures occur as a result of long-term excessive exposure to fluoride (total intakes of 14 mg fluoride per day), and evidence suggestive of an increased risk of bone effects at total intakes above about 6 mg fluoride per day.

Vitamin B9, also called folate or folic acid, is one of 8 B vitamins.
- Folic acid is the synthetic form of B9, found in supplements and fortified foods.
- Folate occurs naturally in foods.
Folic acid is crucial for proper brain function and plays an important role in mental and emotional health. It aids in the production of DNA and RNA, the body's genetic material, and is especially important when cells and tissues are growing rapidly, such as in infancy, adolescence, and pregnancy.
Folic acid also works closely with vitamin B12 to help make red blood cells and help iron work properly in the body.
Rich sources of folate include: spinach, dark leafy greens, asparagus, mustard greens, brussels sprouts, beans, soybeans, root vegetables, whole grains, oranges, avocado.
