Doctors Best - Best D-Phenylalanine 500 mg. - 60 Vegetarian Capsules

Doctors Best Best D-Phenylalanine is a non-protein amino acid related to the essential amino acid L-phenylalanine. D- and L-phenylalanine are structural mirror images of each other. A small amount of D-phenylalanine may be converted to L-phenylalanine in the body. D-phenylalanine is reported to inhibit an enzyme that degrades enkephalins, which are naturally occurring substances in the body that belong to the class of compounds known as "endorphins."


Frequently Asked Questions:

Do you test your products for heavy metals and pesticides, etc.?

We receive Certificates of Analysis from all our ingredient suppliers. These certificates specify the maximum allowable amounts for any impurities and report the precise amounts of impurities present. We always strive to use the purest ingredients available.

 
What is HPLC?
 
HPLC stands for "High Performance Liquid Chromatography." This is an analytical lab testing method that is used to quantify the active ingredients. It is considered to be a very sensitive and accurate test. HPLC testing is a tool recognized as a quality benchmark for herbal extracts.

 
What are cellulose and modified cellulose produced from?
 
Vegetarian capsules are made from cellulose, a non-animal product, which complies with cultural and/or vegetarian requirements. The capsules are certified with Kosher and Halal. Modified cellulose is derived from high quality wood pulp.

 
What are the "Other Ingredients" and why are they used?
 
Various ingredients are used as flow agents and aid in the production of tablets to keep the machinery running smoothly and the capsules filling correctly.  Similarly croscarmellose sodium, which is a cellulose derivative is used to help the tablet to dissolve in the stomach.

 
Is there a limit to how many vitamins can be taken safely in one day?
 
While our bodies need vitamins and minerals, like other things, if taken in large amounts they may adversely affect health. Large amounts of anything can be toxic. It is important to follow all label directions and discuss any concerns with your physician.

 
I am somewhat confused on how to take the DRB products. On many of the labels the Suggested Adult Use will list something along the lines of: Take 2 capsules daily, but it does not state whether they should be taken together or separately. What is the correct usage?
 
Unless otherwise specified on the label, the product may be taken together or separately.

 
What is modified cellulose and is it safe?
 
Modified cellulose is derived from softwood pulp. Cellulose is modified by adding substituents such as methyl, propyl, hydroxypropyl to improve its functional properties (eg. film forming viscosity).  The finished product contains no residual solvents. Modified celluloses are used in many pharmaceuticals and nutritional supplements.
