Safety and Sources of PQQ

Interviewer:  Are there food sources of PQQ and can we get what our body needs through food?  Or do we still need maybe to supplement?

Dr. Derrick DeSilva:  You know, there are food sources.  Believe it or not one of the greatest sources, one of the greatest sources of PQQ is human breast milk.  We can find it in beets, potatoes, and some of the vegetables out there.  But, again, this is another one of those ingredients, nutrients, I shouldn't say ingredients, nutrients that our food supply is so deficient in vitamins, minerals, nutrients.  So deficient.  Example.  A pound of spinach today has 40 to 60 percent less of the nutrient value than it did a couple of decades ago.

Interviewer:  Uh-hmm.

Dr. Derrick DeSilva:  Why?  Because of all the processing.  Because of the, all of the things that we don't do that we did many years ago.  The density, the nutrient density is extremely low.  So, just like anything else, you're not going to get the required amounts if you will through the food.  So this is why supplementation is so important. 

Interviewer:  Talk a little more about the supplementation then.  What kind of doses are we talking about if we go the supplement route with PQQ?

Dr. Derrick DeSilva:  20 milligrams.   

Interviewer:  Okay.

Dr. Derrick DeSilva:  I think 20 milligrams once a day is an appropriate dose.

Interviewer:  Okay.  How about the safety of the product?  And talk about some testing that's been done and those results?

Dr. Derrick DeSilva:  That's one of the first things that we have to deal with.  You know?  This is not one of those ingredients.  This is not a stimulant.  This is not something that's going to affect your blood pressure.

Interviewer:  Um-hmm.

Dr. Derrick DeSilva:  This is not something that's going to affect your blood sugar.  It's not one of those stimulant type ingredients or nutrients.  So safety data, human safety data, all right...

Interviewer:  Um-hmm.

Dr. Derrick DeSilva:...and this is, there's rat data and there's human safety data, is extremely safe even in very high doses.  But I tell my patients and I tell everybody this, the reason we print directions on the bottle is so that you follow the directions.  You don't make stuff up.

Interviewer:  Um-hmm.

Dr. Derrick DeSilva:  We've written the directions, follow the directions.  Period.  End of story.
