Selenium Overdose is a real phenomenon that has been documented in many areas around the world that have high selenium content in their water and their soil. It has also been documented in people taking large doses of selenium supplements for long periods of time. So, it is important that if you do choose to supplement with selenium that you be aware of selenium overdose symptoms and the appropriate and toxic dosages.

It is interesting that few people are aware of selenium toxicity - even though it is relatively EASY to have a selenium overdose and it occurs relatively frequently; yet it seems that just about EVERYONE is concerned about an Overdose on Vitamin D even though it is extremely DIFFICULT and there are very few instances of it- and NO instances of it from natural sources.

But Selenium Overdose has and does occur both in nature and from supplements.

How We Know about the Symptoms of Selenium Toxicity

There are many areas that have very high naturally occurring selenium levels. And animals that graze are particularly susceptible to selenium toxicity. But humans have been affected too- mainly in areas with high selenium levels in the WATER, as most humans don't eat the large amount of selenium containing foods that would be required in order to become toxic from foods grown in high selenium areas. But selenium overdoses in nature can and do happen.

Selenium toxicity also can and does occur from taking selenium supplements in too high a dose for too long. Because too LOW selenium levels can contribute to health problems like:

• • Selenium Deficiency Heart Failure
• • A Weakened Immune System
• • Complications of Influenza
• • Some Cancers
• • Thyroid Problems

So, there are possibly many good reasons to take selenium supplements. But it's extremely important that the Selenium Dosage you choose - IF you choose to supplement at all - is 'Just Right'. In other words, it needs to be high enough for you to receive any health benefits that it may provide, but not too much to cause selenium toxicity.

Signs and Symptoms of Selenium Overdose

So, there are many signs and symptoms of Selenium Overdose- some occur very early and some occur much later

• Early Signs: Some of the early signs of Selenium Toxicity are endocrine hormone disturbances- particularly thyroid issues.

  Poor hair and nail growth are early signs that are probably the easiest to notice. Interestingly, thyroid problems are also a Sign of Selenium Deficiency as well!

• Later signs: One of the later signs of selenium toxicity are fatigue- particularly because of thyroid and adrenal gland dysfunction. *
