Question 1

Countryquestion fot the seller:  which country do you source your quercetin?

Accepted Answer

This is a product of the United States

Question 2

where are these manufactured?

Accepted Answer

Where they are made is not necessarily where they are sourced. Double Woods does not appear to state where they have sourced this product.

Question 3

200mg of Bromelain equates to how many MCU units of bromelain, which is the correct measurement for bromelain thank you

Accepted Answer

The measurement of enzymatic activity is very complex. Proteolytic enzymes can be standardized using different activity-measuring units, including Milk Clot Units (MCU/mg), Casein Digestion Units (CDU/mg), Bromelain Tyrosine Units (BTU/gram), Rorer units, FCC Papain units (PU), and more.

One FCC Papain Unit (PU), for example, is defined as that quantity of enzyme that liberates the equivalent of 1 µg (or mcg - microgram) of tyrosine per hour under the conditions of the assay. This procedure is sometimes used to determine the proteolytic activity of bromelain. The assay is based on a 60-minute proteolytic hydrolysis of a casein substrate at pH 6.0 and 40° C. Soluble casein is then measured spectrophotometrically.

GDU/gram is another measurement of protein digestion (in this case gelatin) by an enzyme, and is a different way to show how much protein an enzyme can digest in a specific time under specific conditions.

Bromelain can come in various strengths, and weights per serving in a formula, affecting the values shown on the labels.  For example, some Bromelain has a documented enzyme activity of 2400 GDU/gram, so 500 mg (500 milligrams, equal to half a gram) of this material would have 1200 GDU enzyme activity per capsule (2400 GDU/gram times 0.5 grams = 1200 GDU per capsule).

Question 4

Is this product in the form of dihydrate, yes or no?  I see the product description, but the way it is worded leaves some room for misinterpretation.

Accepted Answer

I believe it is dihydrate based on "Product description
Quercetin (aka Quercetin Dihydrate) is a plant flavanol from the group of polyphenols."
The only way to know for sure would be to contact the manufacturer.
