Are Your Vitamins Working?

General (Adult):

Eniva® VIBE™, a liquid sold in packets, had only 54% of its claimed 5,000 IU of vitamin A.

Healthy Moments™ Mint Cream Flavor Vitamin Strips contained none of its claimed vitamin A. It also contained 180% of its claimed 2 mg of niacin per strip.

Swanson® Daily Multi-Vitamin & Mineral had only 77.5% of its claimed 400 mcg of folate per capsule.

The Greatest Vitamin in the World had only 85% of its claimed 800 mcg of folate in its suggested nine capsules per day — although this still meets the adult RDA.

WEIL™ Andrew Weil, M.D. Daily Multivitamin for Optimum Health had only 73% of its claimed 10,000 IU of vitamin A (as beta-carotene) per tablet — although this still meets the adult RDA. It also had 251% of it claimed 60 mg of calcium — possibly an oversight of the calcium contributed by di-calcium phosphate, a binding agent listed among its inactive ingredients.
 
Women's:

Nature's Plus® Especially Yours® Women's Multi-Vitamin failed to break apart properly, requiring more than one hour to disintegrate rather than the 30 minute limit established by the U.S. Pharmacopeia (USP). Such products may pass through the body without being fully utilized. It also contained 292% of its claimed 50 mg/tablet of calcium — possibly due to an oversight of the calcium contributed by the di-calcium phosphate in the product.

The Vitamin Shoppe® Multivitamins Especially for Women was contaminated with 15.3 micrograms of lead per daily serving. This is more than ten times the amount of lead permitted without a warning label in California — the only state to regulate lead in supplements — and several times the normal daily exposure to lead. Lead at this level may not in itself be toxic to adults, but lead is stored in the body and unnecessary exposure should be avoided. This product should not be shared with children, as they are susceptible to lead poisoning at levels as low as 6 micrograms per day. This product also contained only 54% of its claimed 200 mg of calcium in its suggested daily dose of two tablets.

Men's:

Now® Adam™ Superior Men's Multi failed to break apart properly, taking 40 minutes to disintegrate rather than the 30 minutes set by the USP.

Win™ Fuel Men's Formula had only 81% of its claimed 4,000 IU of vitamin (although this is still above the RDA of 3,000 IU for men) and only 75% of it claimed 400 mcg of folate.

Quality Concerns and What CL Tested For:

Multivitamins/multiminerals are among those supplements most likely to have quality problems. They contain multiple ingredients and, therefore, more possibility for error. Earlier tests by ConsumerLab.com have found multis that were short on ingredients, failed to dissolve properly, or were contaminated with heavy metals.

ConsumerLab.com tested products for their amounts of several common labeled ingredients: folic acid, calcium, and vitamin A (retinol and beta-carotene) as indicators of product quality. Not all of the products were labeled to contain every one of these ingredients. Therefore, some were alternatively tested for other ingredients — such as vitamin C (ascorbic acid) in the absence of folic acid, and iron or zinc if calcium was not present (see Testing Methods and Passing Score).

Products also were tested to determine if they: disintegrated properly in order to dissolve and be absorbed in the body; and did not contain excessive and/or potentially harmful levels of lead, a contaminant of some mineral and herbal-based products.
Products had to pass testing on all of these criteria to be considered APPROVED. In addition, ConsumerLab.com reviewed the levels of vitamins and minerals to determine if any product provided doses high enough so as to carry a risk of adverse side effects.
 
would have been nicer if they tested more brands. not a great site but not bad. definitely stay away from Genesis Alpha Lipoic Acid, it contained 15% of claimed amount. Designer Protein has 18mg extra cholesterol per serving. Optimum Nutrition has 9.4mg extra cholestrol per serving. I wish the multi-vitamin testing was more in depth but overall interesting site.
 
I'm not impressed with this study I came across. The Twinlab that didn't absorb worth a shit is ranked 48. Absorption wasn't a criteria by this study. If the nutrients don't absorb how the hell can it even be ranked. Minor detail.

Nutritional Ranking of Vitamins and Minerals

A recent independent (non-commissioned) Canadian study examined and evaluated hundreds of American and Canadian nutritional products. The criteria for evaluation and subsequent ranking included:

Completeness of the full spectrum of nutrients
Potency levels
Antioxidant levels of vitamin E, C and beta-carotene
Components for the Glutathione Peroxidase Pathway
Insulin Resistance Defense System components (biotin, pantothenic acid, chromium, magnesium and vitamin E)
Cardiac Health properties (coenzyme Q10, vitamin E and folic acid)
Homocysteine Reduction properties (vitamin B6, B12 and folic acid)
Bioactivity of Vitamin E
Bioflavonoid mixture
Bioavailability (forms of minerals)
Lipotropic factors (choline and inositol)
Potential Toxicities (vitamin A and iron)

Thanks for the awesome info MPPM. I can't seem to find the USANA brand multi, so I'll go with the second best, Source Natural's Life Force Multiple.

Ahh... so apparently the multi I am using from Vitamin World does pass the test...

Then again, there are many factors in play when you're trying to determine the ability of a vitamin to be absorbed. Don't forget that the stomach itself plays a huge role in digesting a vitamin. All the churning and pushing from the stomach walls will definitely speed up the break down of the vitamin. I'm not so impressed with the study as a whole b/c of the lack of "churning" that actually goes on in your stomach.

I say stick with your Twinlab multi and jump to one of the higher ranking multis after you finish.

***There are are a bunch of Twinlab multis that were tested and there was one that was ranked #6 - Twinlab Mega 6 Multivitamin.

i take all my supps the same...low dose and multiple times. It they say you should get 3-4 grams of CEE, i'll take half twice a day...same goes with vitamins and flax oils and shit
 
that ranking that has that twinlab #6 is the same ranking that has the twinlab multitwin I was taking at #48. it didn't absorb worth a shit when I tested it. not sure how accurate the vinegar/water test is but it sounds logical. and what did dissolve was the exact same color as my urine.

but if a supplement doesn't absorb properly what's the difference between taking 1 or 10 grams of it, none, it would be worthless either way.

I emailed consumerlabs and asked how they tested for absorption.

my twinlabs are six feet under :shoot2:
