Adulterated Herbal Supplements – what you need to know


Last week news took hold on the contamination and adulteration of herbal products.

According to this study, Canadian researchers looked at numerous bottles from 12 companies and found that what was on the label was different than what was about 30% of bottles tested. Many of the herbal products were adulterated with fillers such as wheat, rice and soybeans.

The study used a method called DNA barcoding to test the herbal products of interest. CLICK HERE for the BMC study and HERE for the New York Times article.

My Take On This

Unlike the popular belief, the dietary supplement industry is regulated by the FDA. In 1994 the Dietary Supplement Health and Education Act (DSHEA) and in 2006 by the Dietary Supplement and Nonprescription Drug Consumer Protection were developed to regulate the dietary supplement industry. The confusion is that dietary supplements are not regulated like drugs but regulated like food.

The rub is that there is no premarket approval for supplement production. Another words, there is an honor system in place that allows supplement manufacturers to produce products until proven unsafe.

How does DSHEA work?
DSHEA placed dietary supplements as a category of food and created a specific definition for dietary supplements. Further, DSHEA provided FDA with additional enforcement authority, including the ability to remove a dietary supplement from the market the agency considers unsafe.
It’s also the law for companies to abide by Good Manufacturing Practices (GMPs) rules enforce the following:
•    the design and construction of physical plants that facilitate maintenance, cleaning
•    proper manufacturing operations
•    quality control procedures
•    testing final product or incoming and in-process materials
•    handling consumer complaints, and
•    maintaining records.

Again, the FDA does not have the resources to closely oversee over 1000 manufacturing facilities to assure that GMP rules are followed. So there are some companies that intentionally or unintentionally do not follow the rules – and no one will know it until a dietary supplement  proves to be unsafe and then it’s tested.

So clearly this is a problem.

People are  buying dietary supplements and not always getting in the bottle what is written on the label.

DNA barcoding has been questioned by experts in the botanical medicine field as not being an accurate method of measuring adulteration in herbal supplements – CLICK HERE for more on this from the American Botanical Council (ABC).

What should you do?

If your healthcare practitioner is versed in the field (Naturopathic doctor or Integrative MD) no need to worry. Such doctors typically have access to the highest quality of dietary supplements.

For example the nutritional supplement companies I use for patients are from companies with very high manufacturing standards that go beyond what the FDA requires. 90% of dietary supplements I use are from Designs for Health (DFH) or Douglas Labs (DL).

How DFH does things

In addition to strictly following GMP laws, DFH seeks third party company , namely the National Sanitary Foundation (NSF) who frequently visit manufacturing facilities to assure the highest level of manufacturing practices.

Every DFH dietary supplement:

•    Is evaluated and monitored for potential contaminants such as heavy metals, pesticides, and microbiological organisms
•    Is analyzed to confirm the quantity of all dietary ingredients, thereby ensuring the consistency and accuracy of our label claims
•    Methods to test for yeast and mold counts and pathogen screens for e.coli, staph and salmonella
•    Complete analytical screening of all raw materials and finished goods
◦    Independent third party residual solvent screens
◦    Potency verifications and pesticides tested at the Designs for Health analytical lab via High Performance Liquid        Chromatography (HPLC) and Gas Chromatography (GC)
◦    Independent third party heavy metals analysis via Inductively coupled plasma mass spectrometry (ICP-MS)

DFH is the manufacturer of most dietary supplements in XY wellness, LLC including Mr. Happy™.

How DL does things

Douglas Laboratories  has similar manufacturing standards to DFH including ISO-9001 Certification and ISO-17025 Accreditation for in-house laboratories  as well as NSF Certification.  DL are FDA compliant and have rigid procedures and manufacturing practices that are designed to monitor and verify quality throughout every step of the production process.
Their in-house laboratories test and monitor for quality and safety from the raw materials as they enter our facility through to finished goods.  Materials are kept in quarantine until they have passed testing specifications. Materials and formulas are tested for potency, purity, disintegration/bioavailability and stability. Additionally, this year rated DL #1 Rated Healthcare Practitioner Brand Based on Consumer Satisfaction.

DL is the manufacturer of ProstP10x™ and Cysto Renew™

Doggy Bag Message

The study by the BMC should not deter consumers from consuming beneficial botanicals that have minimal to no side effects and can be very effective. There are over 1000 dietary manufacturing supplement companies and for sure, not all have the same manufacturing practices mentioned above  – but most do – especially practitioner brands.  A fabulous resource for consumers , for about $36 a year, that randomly selects dietary supplements and independently test them for purity is

I hope this clears up most of the confusion.

Whole Foods Market “organic” food from China – must see video

If you look at  Dr. Geo’s 12 easy steps to eat healthy, you will find the 12th step is to eat local foods first, then from health food stores. Eating locally means that your food comes from no more than a 400 mile radius – the closer to your residence the better. Local food is sustainable, fresher, tastier and often times with minimal to no pesticides.  A great website for local grown food is

This report shows the 365 Whole Foods Market brand of fruits and vegetables sold as “organic” comes from China. China’s standards of organic food is sub par and often times  highly contaminated. Walmart  also carries organic foods that come from China by the way.

Six months ago while shopping at my local Whole Foods Market I did notice something “rotten” when I decided to read the label of my 365 brand of asparagus – “Product of China” Arrrgh!!!  Who can we trust?  I have known for sometime that “organic” foods from China sometimes have even more pesticides than non-organic foods in the US. This is frustrating.

Take Home Message: Eat locally foods purchased from local farms or farmers market or grow your own. Smaller health food stores typically carry real organic foods and even Whole foods Market carry local and real organic foods as well – you just have to read the label.
