How do you know if you can trust that the supplements will have in them what they say they have in them? Short answer…it’s not easy.
Having a trustworthy source of potent supplements is vital.
Unfortunately, the supplement industry is not well regulated by the FDA or any regulatory organization for that matter. Because of the lack of oversight many supplement manufacturers falsely advertise their products. This practice is all too common in retail stores. In 2015 the New York Attorney General conducted an investigation on store-brand herbal supplements sold at GNC, Target, Walgreens, and Walmart.
This investigation found that four out of five of the supplements they tested did not contain any of the herbs listed on their labels. Four out of five!
Instead, cheap fillers such as powdered rice, house plants, and asparagus were the actual components of the supplements. So, a consumer going in to buy ginkgo biloba at Walmart or valerian root at Target would be getting zero percent of the herb they had hoped to be taking. Additionally, a number of supplements at GNC were found to contain unlisted ingredients used as fillers, things like peanuts and soybeans. So, a consumer taking a supplement in hopes to improve their health may actually be taking something they are allergic to.
Further, even if the supplements do contain the ingredients they claim to, there is a chance that they are not concentrated at the dosage marked on the label. Dr. Erin LeBlanc, a researcher at the Kaiser Permanente Center for Health Research in North Portland, conducted a study she later published in JAMA. She investigated 55 vitamin D supplements produced by 12 different mass market supplement manufacturers. She found that some of the supplements contained only 9 percent of the vitamin D that they claimed to! And, some contained 146 percent of the advertised dose. Only one contained within 10% the amount listed on the label.
This lines up with my own experience. Back in the day when I was just out of school I did some
freelance work consulting for a number of different supplement companies. One of the companies flew me to California with the head of their sales department to present our products to the buyer’s committee at a large health food chain. I was asked a question about our quality control, which I answered honestly. I was fired when we got home because I didn’t lie to the committee. Not even kidding.
What about buying online to save money?
If all that was not unsettling enough, if you buy your supplements on Amazon or eBay there is a chance that they are actually counterfeit products! If a brand is very popular and sells well it is pretty easy for a third-party to copy the company’s labels, manufacture a worthless pill, put it in a bottle that looks exactly the same as the real thing, and then list it on Amazon or eBay.
These fraudulent companies sell the products at a reduced rate so that customers buy it. In reality, the supplements arriving at the front door aren’t supplements at all. There is also a risk of expiration dates being altered, or the products being stored in a way that compromises the quality of the product (think hot warehouse!)
So…what to do?
Fortunately, there are supplement companies out there that are producing quality products. To learn more about how to find them, check out this article I wrote on exactly how to make sure what you are taking is what you think it is. I carry some high quality supplements in my office for patients and clients (and ship as well,) and discount the more expensive products significantly from retail. But that said, as far as I’m concerned it is unethical to tell someone ‘you need this supplement’ then tell them they should buy it from you. If your practitioner tells you this, think hard about whether you’re comfortable having them be your doctor.
Here in Portland if people prefer to purchase locally I will often recommend a local pharmacy called Pharmaca, or I send people to another local source—we have many in Portland including NUNM the local naturopathic college. Pharmaca can ship as well.
There are also some brands that have physician label and mass market label. This means that some of the higher quality supplements that I can offer as a physician can also be purchased from your local health food store. But buyer beware. Just because something is sold at the health food store doesn’t mean it’s good quality. And just because the person working at the health food store swears by a product also doesn’t mean it’s good quality. They are trained by the manufacturers and their reps directly. Remember that job I mentioned above that I was fired from? Truly, it can be sketchy out there.
In short? Vet carefully. Buy quality.
Yours in Health,
Are you looking for vegan dairy alternatives that actually taste good? My last blog post was about why you might want to avoid dairy. If you haven’t considered this, go take a peek at that post before you dive in here! I originally wrote a post in 2011 titled Is it Real or is it Memorex about how to find decent vegan dairy alternatives. At…Read More
I first stopped eating dairy when I was a sophomore in college. I had been a vegetarian for over a year at that point, but dairy was still a staple in my diet. One day I was chatting with a friend about needing to make a little extra money and she suggested that I apply for a job at Mixed Nuts, our college food co-op. These jobs were coveted…Read More
For most of us when our space is organized and clean it’s easier to focus on the task at hand. But we don’t often think about the flip side: Clutter can drain your energy and significantly increase your sense of overwhelm. In the last few years the ‘minimalist’ movement has hit the bookstore shelves and is all the rage in just about every blog and…Read More
Any of you who have been around for a bit have been hearing and reading about my book proposal for a while. And when I say a while, it’s been over 2 years…for this book. There was another proposal before that which I decided to bail on at the last minute—but that’s another story. The way that non-fiction books work, most often, is that you…Read More
I don’t usually use my blog as a platform for very personal posts but today will be one of those exceptions. This is a piece I just published on Medium. As the mother of a child who was born to another mother, Mother’s Day is more than just cards and flowers. My privilege is a profound loss for another woman. So please, understand that on Mother’s day…Read More
