Our office is open Monday – Friday 8:30am – 5:00pm. We also offer Saturday appointments upon patient request. Holidays are not included.
All of our supplements are manufactured here in the United States, but ingredients can come from many countries. Many essential ingredients are simply not manufactured domestically and must be sourced internationally.
The FDA requires testing of all ingredients upon arrival at our manufacturers. This procedure ensures that ingredients in nutritional supplements meet exceptionally high quality standards.a
We frequently get questions about ingredients from China. Here’s the simple fact: avoiding nutritional ingredients from China would virtually eliminate the world’s supply of Vitamin C and many B vitamins. In the end it makes little difference where ingredients come from because testing remains the only way to consistently ensure quality. Our ingredients, regardless of country of origin, are tested rigorously for quality and safety.
All supplements manufactured by Health Products Distributors, Inc. have ingredient specifications that meet or exceed United States Pharmacopeial Convention (USP) standards. All of the ingredients we use in our products meet the highest standards available.For more info, see: https://www.usp.org/frequently-asked-questions/usp-and-its-standards
For further questions there are a few ways to get in touch with us! You can always call the office at 972-428-8060. We’ll get back to you as soon as we can!
Does your supplements contain animal products? How can I know for sure what is suitable for a vegan?
Wherever possible we identify our vegetarian/vegan supplements prominently on the label.
Vitamins are fuel for normal body functions that the body cannot synthesize in adequate amounts. In many cases vitamins act as cofactors to aid enzymes in facilitating metabolism. In this case the vitamins are called coenzyme vitamins.
In order to create supplements with larger amounts of vitamins, manufacturers use synthetic vitamins that are similar to, but not the same as, the coenzyme forms required in the body. In this case the body needs to chemically “process” the synthetic forms in order to make them usable. This process can be complex and utilizes valuable body resources such as coenzyme vitamins, minerals, and ATP (energy).
Coenzyme vitamins (and direct precursors of coenzyme vitamins) are found in foods in relatively small but significant amounts. Some examples of coenzyme vitamins include Vitamin B1 in the form of thiamin diphosphate (or cocarboxylase) and Vitamin B6 in the form of pyridoxal 5’-phosphate.
While coenzyme vitamins usually cost significantly more than the synthesized vitamins (up to 50 times more), they remain affordable because the body only requires them in very small amounts. The body only needs small amounts because there are no in vivo losses related to conversion processes. We include coenzyme vitamins in precise quantities needed by the body.
Currently available coenzyme vitamins include:
- Vitamin B1 in the form of thiamin diphosphate (or cocarboxylase)
- Vitamin B2 in the form of riboflavin 5’-phosphate sometimes called flavinmononucleotide (FMN)
- Vitamin B3 in the forms of  forms of niacinamide (partial coenzyme), nicotinamide diphosphate (NAD), and nicotinamide diphosphate hydrate (NADH)
- Vitamin B5 in the form of panthetine
- Vitamin B6 in the form of pyridoxal 5’-phosphate
- Folate in the forms of 5-Methyltetrahyrofolate (5-MTHF) and folinic acid (5-formyl tetrahydrofolate)
- Vitamin B12 in the forms of methylcobalamin and adenosylcobalamin.
