Question 1

What is the absorbing acid made from?  Why not use a fruit acid?

Accepted Answer

First of all it's Ascorbic acid.  This particular Vitamin C is a brand of ascorbic acid made by DSM which is the last and only Western producer of vitamin C!  All their vitamin C is produced in a world-class DSM-owned facility in Dalry, Scotland. In fact, DSM/Roche was the first company to synthesise vitamin C back in 1938, and has been a leading producer for over 75 years.  Quali®-C is the world’s first branded vitamin C, and buying it guarantees you the peace of mind you can only get from the best supplier.  Also, to further clarify, Ascorbic acid is found in citrus fruits as well as citric acid, but citric acid does not contain Vitamin C.
Ascorbic acid is natural, citric acid is man-made, hence, synthetic.  If you want more in-depth information though about this particular product, visit this website:

Accepted Answer

Question 3

Where are this made ?It does not say it anywhere.

Accepted Answer

It is made in the US.  Doctor's Best is now owned by the Kingdomway Group, a publicly traded company in China.  According to an article I read the primary reason Kingdomway purchased Doctor’s Best was to provide an authentic, manufactured in the USA brand to the rapidly expanding market in Asia.

Question 4

No stearate or stearic acids is wonderful however it does not contain rose hip, isnt that a requirement for vitamin c absorbtion can anyone clearify?

Accepted Answer

Definitely not a requirement. Vitamin C is water soluble, meaning all it needs for absorption is water. Most vitamin C supplements don't contain rose hips.
