Increasing IQ, Cognition and Cure Rate of COVID-19 with Essential Nutrients ( my third book)

 I have just published my third book “Increasing IQ, Cognition and COVID-19 Cure Rate with Essential Nutrients”.  The book is now available as a softcover or Kindle e-book at Amazon. IQ of children born after World War II interests me as it had been rising until it began taking a nosedive in seven countries during the 70’s. My interest in finding out why this “brain drain” was happening came full circle with what I had researched in the 70’s and resulted in my new book. Brain drain is primarily due to environmental chemicals and viruses that impact both brain development, lowering IQ in the very young and killing neurons causing cognitive decline and Alzheimer’s in aging adults. These brain drainers are summarized in my new book.

Philippe Grandjean in his book “Only One Chance” asked the following question: “Could science develop some kind of antidote to counteract brain drain?”  The answer to Grandjean’s question is YES antidotes to counteract brain drainers have now been identified, tested, and are described in my new book. Essential nutrients as brain savers are identified that are scientifically based and tested antidotes to counteract brain drain in children and adults. Two brain savers are identified in my book and described anecdotally as detoxing brain drainers causing attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and seizures in children. Also, the “Crouse Protocol” is described that uses essential nutrients as brain savers and nootropics to reverse mild cognitive impairment (MCI) and possibly prolong and save the lives of those with Alzheimer’s disease, such as my mother.

While writing my new book during 2020 it was discovered that SARS-CoV-2, the virus responsible for the COVID-19 pandemic, was a brain drainer. Also, while writing this book it was discovered that three brain savers not only target the detox of brain drainers but also enhance the immune system. These three over-the-counter essential nutrients as brain savers have been shown during 2020 to make humans more likely to be cured and survive the COVID-19 pandemic.

I hope you find my new book useful and as interesting to read as it was to write. 

Stay Healthy, Dennis

Safety of OSA Augmentation

Safety of OSA Augmentation

OSA and its salt, sodium silicate, are not silica (SiO2 silicon dioxide). Dissolved in water, OSA and sodium silicate can’t be converted to silica and silica is not converted to OSA in the human body. Therefore, the toxicology of silica does not apply to OSA or its salt, sodium silicate. 

It is safe to drink bottled OSA rich water and beer. For a list of waters and beers see appendices I and II. It is also safe to drink handcrafted Silicade made by neutralizing a sodium silicate produced by PQ Corporation and sold online that is 99.5% water soluble (see appendix III). This product is sold by PQ Corporation directly and distributed through Brenntag to many U.S. community water departments that add it to public drinking water. In addition to being a brain saver, OSA provides corrosion protection. This PQ Corporation product meets the ANSI standard specification set by the American Water Works Association (AWWA) for silicates added to drinking water, as it contains only a 0.5% water insoluble impurity222.

OSA is commonly found in rivers, lakes, aquifers, and drinking waters around the world140. Dissolved OSA from soluble silicates added to drinking water in the U.S. is identical to dissolved OSA in beer and mineral waters140,232.  The amount of OSA in drinking water varies widely depending upon the source140.  In the U.S. 160ppm of dissolved silicates as OSA are generally recognized as safe (i.e., GRAS) in drinking water by the FDA221. The adequate intake of water per day is 3 liters for men and 2.3 liters for women. This level of water intake corresponds to a maximum safe level of OSA intake per day of 480mg for men and 368mg for women. Therefore, drinking 4 cups (approximately 1 liter) of OSA rich water each day containing 50 to 150mg per liter of OSA is well below the GRAS level for dissolved silicates.

It is safe to ingest dissolved silicates, such as OSA, at concentrations well below the saturation level (i.e., less than 200ppm of OSA) in order to ensure that they will not become supersaturated and crystallize in the kidney lumen. Ingesting OSA above the saturation level (i.e., 200ppm) can result in kidney stones (a.k.a. nephrolithiasis) in dogs but almost never in humans. There is one report of kidney stones resulting from too much silicate salt, erroneously labeled as silica (SiO2), used as an inactive ingredient (a.k.a. excipient) in several over-the-counter drugs such as Uncaria Tomentosa, Digestive Advantage, and FlexProtein supplements507

Fluoride Filter: How to make your own


Appendix VI – Bone Char Filter Construction

In order to filter the maximal amount of fluoride and arsenic from tap water or Silicade, the water must be adjusted to pH 4.8 with sodium bisulfate and then filtered slowly (i.e. less than 400cc/min) through a bone char filled filter cartridge and finally brought to pH 6.5 with sodium bicarbonate prior to drinking. The flow should be bottom-to-top in order to flush most of the air out of the bone char. The least expensive and most convenient way of constructing such a filter is to purchase an Aquatic Life ion exchange cartridge filter with quarter inch polyethylene tubing from Amazon. Pour out the ion exchange resin and fill the empty filter cartridge with bone char. The filter can be held vertically with two clamps attached to a lab stand (see figure 37).  More details are given below.


Figure 37 – Removing fluoride and arsenic from one gallon of pH 4.8 tap water or Silicade being syphoned through a bone char filter in series with a gravity-fed Brita pitcher style filter

Cut the polyethylene tubing into two different lengths and attach as indicated in figure 37. Use the Brita filter and plastic insert sold with a Brita pitcher style filter to catch the water flowing out of the bone char filter. Use two, one gallon-sized plastic or glass containers. In order to maintain the syphon, one container must be placed on a shelve that is higher than the exit of the outflow tube on the bone char filter (see figure 37). The other container must be topped with the Brita filter and be low enough to catch the outflow of the bone char filter. Start the syphon by sucking on the outflow tube on the bone char filter until water begins to flow. 

How to Prepare and Refill the Bone Char Filter

1.      Remove the threaded end-cap from the Aqua Life filter cartridge and if new, pour out the resin for disposal or if used, pour out the spent bone char for disposal while retaining the o-ring, plastic disk, and two particle filters (i.e. top and bottom particle filters).

2.      Rinse the empty filter cartridge and refill it with first the bottom particle filter and then the bone char until the top particle filter sets gently on the bone char and the plastic disk on top is flush with the top of the cartridge.

3.      Slide the o-ring on just above the cartridge threads and screw on the top cap being careful to not cross threads.

4.      Prepare pH 4.8 tap water or Silcade with sodium bisulfate microprills from Loud Wolf sold by Amazon.  Use a temperature compensated pH meter ($10-$20 from Amazon) and a set of Norpro measuring spoons, including “dash” and “drop”. Try starting with one level “dash” of sodium bisulfate with stirring per gallon and, if insufficient to lower to pH to 4.8, try adding one level “drop” of sodium bisulfate with stirring at a time.

5.      Syphon one gallon of pH 4.8 tap water or Silicade through the filter flushing the filter and then leave the filter filled with the pH 4.8 tap water or Silicade to soak the bone char for three days prior to use as a fluoride and arsenic filter. 

Bone Char Filter Performance

This bone char filter will remove 72% of fluoride from 50 gallons of tap water or Silicade containing 0.5ppm fluoride resulting in tap water or Silicade with only 0.14ppm of fluoride. With distilled water containing 1 ppm fluoride, 100% and 92% of the fluoride is removed after 25 and 50 gallons of tap water has been filtered, respectively. The fluoride capacity of this filter is 200mcg of fluoride per gram of bone char in tap water or Silicade.

After filtering 50 gallons of tap water or Silicade the bone char must be refilled. After filtering 75 gallons of tap water or Silicade, the bone char filter only removed 21% of the fluoride595.

This bone char filter will also remove approximately 60% of arsenic reducing arsenic levels to below 10mcg/liter (10ppb)603 the maximum contaminant level (MCL) of arsenic in drinking water in the U.S.
