New York AG: Many Popular Store-Brand Supplements Are Phony - Fox, 2/3/15 -
"New York Attorney General Eric Schneiderman is going
after four major retailers - GNC, Walmart, Target and Walgreens - for selling
store-brand supplements that are mislabeled and contaminated ... Wal-Mart fared
the worst, with only 4% of its products containing the plant listed ... At
Target, 41% of the supplements had the ingredient advertised, compared with 22%
at GNC and 18% at Walgreens"
clinical studies on vitamins flawed by poor methodology - Science Daily,
12/30/13 - "Needed are new methodologies that accurately
measure baseline nutrient levels, provide supplements or dietary changes only to
subjects who clearly are inadequate or deficient, and then study the resulting
changes in their health. Tests must be done with blood plasma or other
measurements to verify that the intervention improved the subjects'
micronutrient status along with biomarkers of health. And other approaches are
also needed that better reflect the different ways in which nutrients behave in
cell cultures, lab animals and the human body ... most large, clinical studies
of vitamins have been done with groups such as doctors and nurses who are
educated, informed, able to afford healthy food and routinely have better
dietary standards than the public as a whole ... More than 90 percent of U.S.
adults don't get the required amounts of vitamins D and E for basic health ...
More than 40 percent don't get enough vitamin C, and half aren't getting enough
vitamin A, calcium and magnesium ... The cancer reduction would be in addition
to providing good basic health by supporting normal function of the body,
metabolism and growth ... If there's any drug out there that can do all this, it
would be considered unethical to withhold it from the general public. But that's
basically the same as recommending against multivitamin/mineral supplements"
Some Fish Oil Supplements Fishy on Quality - WebMD, 12/7/11 -
"None of the fish oil supplements contained
contaminants, such as lead, mercury, or PCBs, that exceeded levels set by
USP or the European Union ... the total PCB amounts in four brands (CVS
Natural, GNC Triple Organic, Nature’s Bounty Odorless, and Sundown Naturals)
were below the USP safe limit but within the range that would require a
warning label under California’s Proposition 65, 90 parts per billion ...
For the report, the consumer agency purchased three lots of 15 different
top-selling brands of fish oil supplements online and in the New York
metropolitan area ... Two of the three samples of Kirkland Signature Enteric
1200 fish oil supplements had an enteric coating (designed to prevent a
fishy aftertaste) that did not disintegrate properly. The coating may break
up in the stomach rather than in the small intestine, as desired for proper
absorption by the body" - Note: So those bargains at Costco may not
be such a bargain if they aren't absorbed.
Many multivitamins don't have claimed nutrients - MSNBC, 6/17/11 -
"Among the supplements that had too little of a
particular nutrient were Trader Joe’s Vitamin Crusade (just 59 percent of
the vitamin A advertised on the label), Melaleuca Vitality Multivitamin &
Mineral (just 42 percent of the touted vitamin A) and All One Active Seniors
(less than 2 percent of the beta-carotene, 73 percent of the retinol and 49
percent of the vitamin A listed on the label) ... Particularly worrisome
were high levels of certain nutrients in some of the children’s
multivitamins. For example, Hero Nutritionals Yummi Bears, if given to
children at the suggested dose, would exceed recommendations for Vitamin A
in youngsters aged 1 to 3. Higher levels of the nutrient in kids have been
linked to liver abnormalities, bone weakening, and problems with the nervous
system ... ConsumerLab also tested several pet supplements, one of which,
Pet-Tabs Complete Daily Vitamin Mineral Supplement for Dogs contained lead
at unhealthy levels"

Most ginkgo products fail quality testing - Nutra USA, 11/18/08 -
"Some companies put less of it in their products
than they claim or use ingredient that has been adulterated with inexpensive
material that can fool non-specific tests ... companies continued to make
products with little to no ginkgo in them, leading Consumerlab to suggest
“ginkgo is among the most adulterated herbs.”" - That's why I stay
with the top brand names. They have more to loose with bad press. I also
think that's why some studies show benefits with certain supplement while
other studies don't. I've been taking Nature's Way, Ginkgold. I get the
paid version of Consumerlab and I thought it was strange that they didn't
test that brand. - Ben
(Curcumin) review - ConsumerLab.com, 2/6/08 -
"ConsumerLab.com found a popular brand to contain 18.7 mcg of lead in a
daily serving — the highest amount it has ever reported. Another brand was
contaminated with 8.3 mcg of lead. These amounts are well above those to
which people are normally exposed and should be avoided ... two other
products provided only 11.5% and 49.5%, respectively, of expected curcumin
compounds. A fifth product did not specify the part of the plant used — a
FDA labeling requirement" - Note: I get the paid version and it was
NSI® Nutraceutical® Sciences Institute Superior™ Turmeric Curcuma Longa that
contained the 18.7 mcg of lead and Solgar® Standardize Full Potency™
Turmeric Root Extract that contained the 8.3 mcg. There wasn't any that
failed that I call "brand name".

bacteria, but contained fewer species of organisms than the label claimed.
More than 30% of all supplements were contaminated with other microorganisms
and 50% of the non-refrigerated products were completely dead. Dead
probiotics have no impact on improving intestinal function or restoring the
