Supplements from Amazon…. hit pause !
by Dr. Alan Kadish NMD
As Amazon becomes more of an access point for our supplements along with many other goods perhaps, we should take a moment and pause. Are you wanting real value for your dollars or are you looking for the feel good, at too good a price experience ?
Ask yourself a quick question, can you afford to substitute low quality and price for good nutrition ? I’m going to suggest otherwise as your health is on the line so let’s look at the facts from a recent study published in the October issue of Vitamin Retailer.
Now company, a large commercial enterprise in the supplement field was taking a loss in sales of a number of products*, with some pricing so low that it would be inconceivable that the real contents were what was claimed. They bought multiple Amazon products and sent them to an independent lab along with evaluating the same samples, in their facility.
The recent focus was on phosphatidyl serine also known as PS. Some of the suppliers were charging up to 70% lower fees than their company discount pricing. Not surprisingly after taking 43 samples, all purchased from Amazon, only 2 samples actually passed……rethinking your next purchase ? But wait the results get worse. Of the 36 failures 17 were found to contain less than 10% of the labeled amount.
In the industry when your purchasing quality materials in bulk for an enterprise level organization there are a number of limited suppliers and the price is well known. Where quality manufacturers make the difference is in their quality control, starting from the receipt of the highest quality raw materials and ending with testing of their finished supplements.
Did you know that supplements are regulated by the FDA ? As a good example of the minimum regulatory process for all manufacturers, known as current Good Manufacturing Practices (cGMP) see the article “ Can You Trust Your Supplements” by Jon Barron and appreciate the complexity and high costs. Is this adaquate regulation….. keep in mind it’s the MINMUM requirements to meet the regulations.
As one example of real quality control at a much higher level in the supplement industry see Vital Nutrient’s information at: Supplement Quality Is Our Top Priority. Please keep in mind at the Center of Health we have been only using quality products since the 1980’s. Many good firms started with the proposition that quality is essential and manufacture supplements well worth their price giving our patients results.
To get the costs down some manufactures source the lowest cost and quality products, fake the contents and/or make label claims that don’t add up to the real deal, but look pretty similar and deceive the consumer. Unfortunately, there are other ways to scam the system such as substituting the amino acid for the PS compound to try to fool the labs. Two manufactures of the 43 tested did just that which sent the results into ridiculously high fraudulent levels, a clear red flag.
As a consumer who is looking to impact their health in a positive manner let’s purchase real products that actually meet the claims and are indeed worth the purchase price.
Take Aways:
- Purchase your supplements from reputable companies
- Two options include distributers: Natural Partners and Emerson Ecological
- If it’s too inexpensive to be real…… it probably is
*Previously tested products: CoQ10, Acetyl-l-carnitine, SAMe
NOW Raises Concerns About Phosphatidyl Serine Supplements Purchased on Amazon.com
Nicholas Saraceno | September 9, 2020
Following NOW’s (Bloomingdale, IL) report earlier this year of CoQ10, acetyl-l-carnitine and SAMe supplements with alarming quality and labeling problems sold on Amazon, NOW has identified similar serious failings in the phosphatidyl serine (PS) category, the company stated.
NOW purchased and tested a group of PS products on Amazon, choosing this particular supplement for several key reasons. According to SPINS data, NOW is the leading seller of PS in natural food stores, and the company knows the product well. NOW staff noticed that its PS sales were declining on Amazon, and investigated. NOW found that the top selling brands on Amazon were offering prices that averaged 70 percent below NOW’s already discounted prices. Knowing that the prices looked “too-good-to-be-true,” it made sense to test and verify potencies. Because PS is an expensive supplement, the incentive is high for marketing brands to put extra funds into Amazon-sponsored fees. NOW had previously tested examples in this and other categories and found these semi-private label brands sold exclusively on Amazon to display faulty labeling and be of poor quality. When most quality brands sell 100 mg PS as the standard potency, it’s questionable to see high potencies such as 400 mg or 500 mg.
NOW’s initial analysis of simply reading label information found multiple problems. PS is a complicated supplement, which makes it easier to have confusion. Many of the brands included in this report list a high potency, such as 500 mg, on the front label (and Amazon’s keyword) panel, yet the side panel often states that amount per 2 or 3 capsules. Others were more deceptive by adding things such as “Phosphatidyl Serine Complex” in order to show a high potency value, even when the actual potency of PS would only be 20 percent of that number. Here are some examples:
| Absonutrix is deceptively labeled as “Phosphatidylserine Complex 500 mg” |
| Naturebell is deceptively labeled as “Phosphatidylserine 20% 400 mg per 2 Cap serving”.
Havasu brand also labels this way “Phosphatidyl Serine 20% 100 mg” |
| longlifenutri is mislabeled as “Phosphatidylserine 500 mg (per 2 caps) (standardized to 20%)” |
| NUSA brand label is unclear how much PS is in each capsule |
| Both Earth Natural brands mislabel listing PS as 500 mg on the front, but only 50 mg per cap on the side fine print |
| Correct labeling should be “Phosphatidyl Serine 100 mg (from 500 mg Sunflower/Soy Lecithin Complex)” if the raw ingredient is 20% PS from Complex, or simply “Phosphatidyl Serine….100 mg”. |
A total of 43 samples were purchased on Amazon, generally three bottles of each brand, and tested to verify results. Three of these were NOW brand and results on these were 100 to 108 percent of label claims. Of the remaining non-NOW brands, two samples were discarded when results revealed 2.5 times the label potency claim so it was suspected these products were spiked with added Serine in order to fool testing. Two samples passed potency (not included in this report), while 36 samples failed. Of the 36 failures, 17 of these products contained less than 10 percent of the labeled value.
“That’s a shockingly poor failure rate, but not really a surprise based upon our previous experience testing supplements sold on Amazon,” said Dan Richard, vice president of global sales and marketing. “Amazon has to find a way to raise the bar on products they sell, especially today with people buying more supplements from Amazon in order to stay healthy.”
The results are reported in the chart below, which NOW tested by HPLC both by their in-house labs and independently at Eurofins Labs.
