Lead is everywhere. It was commonly used in paint, gasoline, plumbing pipes, jewelry, bullets, fishing weights, glazes, and cosmetics. Some regulations are now in place to eliminate lead’s incorporation into these products, but in many cases, it is still being used. There is no doubt that we are exposed to lead every day, but with knowledge of where that lead is coming from, better decisions can be made that will influence our long term health and well-being.

Alzheimer’s A Biological Model of Prevention – Finally!News media are replete with alarming statistics about the current and future incidence of Alzheimer’s Disease. A recent CBS headline announced the latest data from the Centers for Disease Control predicting already troubling rates will “soar” in coming decades, with the number of cases potentially doubling by 2060 to almost 14 million Americans. With its impact going significantly beyond a personal toll to create devastating burdens on the family and the economy, Alzheimer’s Disease has become a disturbing public health phenomenon. What is most frightening is that despite billions of dollars spent annually on Alzheimer’s research, we don’t seem to be any closer to pinpointing a cause or finding a cure.

Birth ControlI watch a bit of television now and again, and repeatedly see a commercial for a birth control pill. It looks quite glamorous to be taking it. Granted, at the tail end of the commercial it states many of the bad things contraceptive pills are widely recognized to cause. But the real impact of what birth control pills do to female bodies is never discussed and what is discussed is completely glossed over.

How to Treat Iodine Deficiency

The decision to start a regimen of iodine supplementation should be based on a detailed nutritional, physical, and laboratory assessment. Once the need is established, some clinicians go straight for supraphysiologic dosing while others may implement a diet rich in sea vegetables to get the job done. How do you decide where to start? The first step is understanding the different supplement forms of iodine.

ThinkstockPhotos-911966802I’m excited to do this practical piece on iodine therapy because I field a lot of questions on the matter of assessing iodine status, implementing the right iodine supplement, and monitoring that therapy.

Iodine performs some crucial roles in the body, but it never acts alone. Therefore, to assess iodine deficiency, it’s imperative to test iodine and its partners - selenium, iron, magnesium, zinc, B6, cortisol, and glutathione. To assure optimal outcomes, it’s also important to check for endocrine disruptors like bromine, cadmium, mercury, and arsenic.

Well-rested woman waking up in the morning

Glycine has a calming effect on the brain – it helps you wind down and prepare for sleep. Its role as an inhibitory neurotransmitter has been unfolding over many years of ongoing research efforts.

Easily one of the most versatile amino acids, glycine serves as a building block to proteins (collagen, the most abundant protein in our body, is one-third glycine), and is heavily utilized for the production of heme, DNA and RNA synthesis, glutathione formation, and for enriching the body’s capacity for methylation reactions [1] [2].

Doctor and colleague planning marketing strategyI recently helped a doctor with three problems he was having in his practice:

  • First, he was not getting enough new patients in the door.
  • Second, he had recently purchased new equipment and the utilization (sales) were far less than expected.
  • Third, he recently completed a respected industry certification program, but patients were not beating down the doors to take advantage of his new expertise.

He seemed to be doing all the right things…

X-Ray of teeth with fillings that contain mercury

Mercury is one of the most toxic heavy metals. There are numerous natural and man-made sources of mercury, but the most concerning are the ones we are exposed to daily. Mercury is known to affect the nervous, circulatory, immune, reproductive, and digestive systems, along with organs such as the kidneys, lungs, and gastrointestinal tract. Mercury primarily targets sulfhydryl groups (sulfur) and selenium, for which it has a high affinity. Later in this blog is a list of the most common sources of mercury exposure, but before we get into that, it is important to distinguish the three different types of mercury and their common exposure routes.
