How Tap Water is Harming Your Thyroid

Paige Clarke Theragoods

Tap water is polluted with pesticides, pharmaceutical drugs, heavy metals, and many other environmental toxins. All of which are harmful to your health.

When it comes to your thyroid, one of the biggest concerns is fluoride. And sadly, it’s intentionally added to local water supplies to promote healthy teeth.

However, research shows that fluoride actually increases the occurrence of cavities by as much as 27%. Fluoride has also been linked to:

  • Heart disease
  • Brittle bones
  • Neurological damage
  • Cancer
  • Attention Deficit Hyperactivity Disorder (ADHD)

Fluoride’s Link to Hypothyroidism

In 2015, a large observational study found that drinking fluoridated water is associated with a 30% higher risk of developing hypothyroidism (a.k.a. underactive thyroid).

This statistic is true for fluoride levels as low as 0.3 mg per liter. However, the U.S. recommends adding 0.7 mg of fluoride per liter of water. More than twice as much!

Scientists in this study also compared a community with fluoridated water to a second community without. They found reports of hypothyroidism were twice as high in the fluoridated region.

What is Hypothyroidism?

The thyroid is the body’s largest endocrine gland. It’s responsible for producing and secreting thyroid hormones. And these hormones play many vital roles in the body. In fact, all metabolically active cells rely on thyroid hormones to function properly.

Hypothyroidism is the most common form of thyroid disease. It results in an underproduction of thyroid hormones, which causes imbalances and dysfunction throughout the body.

Common symptoms include:

  • Weight gain
  • Fatigue
  • Cold intolerance
  • Constipation
  • Brain fog
  • Poor immunity
  • Brittle hair and nails
  • Dry skin
  • Depression
  • Poor memory
  • Achy joints
  • Muscle cramping

How Fluoride Negatively Impacts Your Thyroid

The thyroid gland is highly sensitive to the effects of fluoride. In fact, fluoride was once used to reduce the production of thyroid hormones in those with overactive thyroid glands (hyperthyroidism).
The therapeutic dose required to slow the synthesis of thyroid hormones was as low as 2 to 5 mg per day. Today, the average American consumes 1.6 to 6.6 mg of fluoride daily from tap water.

Research has also found that fluoride builds up in the thyroid gland more than any other soft tissue in vertebrates (except the kidney).

Studies have revealed several possible mechanisms in which fluoride may harm the thyroid, including:

  • Blocking hormone receptor sites
  • Physically damaging thyroid tissue
  • Preventing the conversion of inactive thyroid hormones to their active counterparts
  • Worsening the effects of iodine deficiency

In Conclusion

There’s plenty of scientific evidence linking fluoride in our drinking water to hypothyroidism (as well as many other serious health conditions).

In addition, the lack of safety studies doesn’t prove fluoride is safe. In fact, the U.S. Agency for Toxic Substances and Disease Registry lists fluoride as one of the top 20 toxins considered most risky to human health.

Yet, it’s still added to our water!

For optimal thyroid health, reducing your exposure to fluoride is essential.

This is one of the many reasons we created the TheraH2O water filtration system. It effectively removes fluoride (and all other contaminants) from your drinking water to make it as pure and natural as possible.
