Famous Starlet, Found Dead due to Drug Overdose!

Country Crooner alleged to have been killed by Heroin Addiction!

Caught in the Act! Former Child Star Abusing Pain Medications!

These are all too familiar headlines that run across every media outfit. It's a disturbing cry of attention where the troubled few found themselves under the critical eye of the society's cruel microscope. Substance abuse became more than a mere condition, it became a fad of the lonely and confused individuals who tried seeking something out of the wrong things.

Being proverbial, too much of the bad stuff can definitely lead to an equally disastrous bad outcome. Either you end up wasted and literally becoming your own worst enemy; or you end up facing Death squarely on his ominous face.

Surprisingly enough, it seems that even with the good stuff, too much of it can be dangerous and life-threatening. In world that is struggling against the gravitational pool of obesity and health hazards, some of the overly enthusiastic health buffs are unknowingly causing more harm than help to themselves. One of the good stuff that can be a potential threat upon abuse or excess intake is the seemingly "harmless" VITAMINS.

Liver Fibrosis is the formation of scar tissues as the liver's response to injury. Since the Liver functions as storage and for the metabolism of substances, it is expected that Vitamin A Toxicity will include liver damage as symptom since the liver metabolizes Vitamin A into retinoids for it to be absorbed by the body.

  • Birth Defects. Pregnant women should be monitored about their Vitamin A intake to avoid and prevent birth defects on their babies.

With the brief descriptions of how too much Vitamins can do to our health, it is imperative, as a hopeful wish, that people would take into consideration the measures and interventions they plan to incorporate in their lifestyles. Vitamins are not that bad. We need them. They serve a great deal of purpose and benefit for us as we strive to keep ourselves fit and healthy. But taking in more than what is required does not equate to more of the health benefits promised, and as tackled, Hypervitaminosis has been proven to be a crucial health risk and worst, to be a potential cause of demise.

      This is an interesting and timely article for me. I started taking megadoses of my vitamins (in accordance with the label), and I thought I was doing a good thing for myself. I started getting a terrible acne breakout, and I've never had acne before! For months, I tried everything to get rid of it, and finally I realized, it was the vitamins! There are many studies that link an overdose of B12 to acne. As soon as I cut back on the dose, the acne went away.

      Important topic. More is not always better and while many of the water soluble vitamins will be excreted in the urine, some are more dangerous than others and can cause harm such as what you listed. Voted up, useful and will SHARE.
