What is Concentrace?
Many men have been asking me, "What is Concentrace?" Concentrace
Drops is a product that I have used from time to time, because it a source of 1) ionized minerals for maximum absorption and
2) a broad array of minerals, including the trace ones that the body needs in
Our modern soils are so
depleted of minerals of virtually all types that this certainly seems
attractive, since there are many common issues that can interfere with mineral absorption,
including low hydrochloric acid
levels in the stomach, black tea, soy, etc., etc. In other words,
quite easy to still end up deficient even if you are conscioustious and
eat a well-rounded, whole foods diet.
The problem that you'll find with Concentrace Trace Minteral Drops is to
out just exactly how much of what minerals is actually contained in the standard
dosage prescribed on the bottle. However, in an obscure location of their
site, I did find the
Concentrace Analysis Summary, which has a complete list of mineral
concentrations.  You can see some of this in Table I below
bottom of this page.

The only problem with this list, for most of us non-chemists, is that it is in parts per million. The
standard dose, as directed on the bottle, is 40 drops or about 1/2 teaspoon, so
we need to somehow convert the ppm to a 1/2 teaspoon. The key conversion
factor that I am assuming is that 1 ppm is equal to 1 mg/L. This should be
a reasonable assumption and is quite common with water-based solutions, but keep
in mind that I have not officially verified this yet with the parent company
However, I do think this seems to be a
pretty reasonable assumption as the total magnesium that I come up with is 250
mg, which is reasonably close to what is on the bottle. Other numbers,
such as chloride, are fairly close as well.
So the bottom line is that their concentrations may have changed a little over
time, but I still think we can draw some interesting conclusions, both positive
1. Magnesium. Concentrace is clearly a FANTASTIC choice of easily
absorbed magnesium. Magnesium can help with sleep, which in turn can
improve testosterone levels. Magnesium can also help improve heart
disease, which can help erections. Magnesium is simply a ubiquitous
molecule that is involved in 100's of different metabolic pathways.
2. Boron. Getting about a mg of ionic Boron is excellent as well.
As I document in my link on Testosterone and Boron, you get about 1.5 mg/day of
boron on average probably and the experts recommend up to about 3 mg/day.
So this amount should be a nice addition to your (hopefully) well-rounded, whole
3. All Other Minerals. What was surprising is the very low amounts
of virtually all other standard minerals. For example, the daily
requirement for potassium is about 4,700 mg, but 40 drops will only provide
about 5 mg. Calcium and selenium are also less than a mg. Thus, with the
exception of magnesium and boron, Concentrace Trace Mineral Drops provides very low
amounts, well below 1% of RDA or AI.
4. Exotic Minerals. Concentrace does provide some of the more exotic
minerals that the body does need in trace amounts. Rubidium is a classic
example. There is no RDA or AI for rubidium, yet your body does use it in
trace amounts for, among other things, the CNS (Central Nervous System).
Studies have shown that low rubidium levels can negatively lead to mood
disorders and depression in dialysis patients, who are known to have depleted
rubidium levels. 
However, even here, it seems hard to get excited, because Concentrace provides
such a low dosage. We eat between 1 mg and 5 mg per day of rubidium in our
foods. Even coffee and tea have a good supply. The very minute
amounts in 40 drops seem, quite frankly, to be almost negligible.
5. Heavy Metals. CAUTION: And here is where I see the problem with
the Trace Mineral formulation: it has a number of heavy metals, including
cadmium, arsenic lead, mercury and aluminum. Now, admittedly the amounts
are very small. But I do not think of all the dosages can be so easily
dismissed. For example, the dosage of arsenic in Concentrace is about 2.07 parts per
million, which is in the area of rice, something that many experts are concerned
So, yes, it is a great source of magnesium, but
you could simply use ZMA as a well-absorbed alternative
and get a nice dose of zinc as well. I simply do not see the big advantage
in using Concentrace daily and risk some of the heavy metal exposure.
