Dr. Oz Vitamins & Supplements Test with Vinegar at 98 Degrees


Doctor Oz did a test on the his segment on Vitamins & Supplements to test if a vitamin and supplement is effective by heating the pill in a vinegar bath.  Dr Oz said since most Vitamins and Supplements are not supposed to be slow release, you can do this test at home to check to see if your body can actually absorb the Vitamins and Supplements that you take.  The reason Dr. Oz’s vinegar test works is because the vinegar mimics the acid in our stomachs, so if the vitamin and supplement do not dissolve in the vinegar, then they will not dissolve in our stomach either.  Vitamins & Supplements Test with Vinegar

Dr. Oz’s Vinegar Test for Vitamins & Supplements

1.  Warm a small pot of vinegar until it is 98 degrees.

    This test is nothing but a myth! Putting a pill in vinegar in no way shows what that same pill does in your stomach. Is your stomach full of vinegar to digest your food? The answer would be no. It uses hydrochloric acid for digestion. So, it’s not fair to put vinegar up against acid found in the stomach—it’s like comparing apples to oranges.

    No, vinegar is not in our tummies, but if a vitamin dissolves in vinegar within 30 minutes…well….then obviously it would digest in our MUCH STRONGER stomach acids.
    So this would then show if YOUR particular vitamin COULD be more readily absorbed or if you need to try another brand.

    Yes it might give you a warm fuzzy feeling if you pills happen to disolve in vinegar, but it doesn’t mean that pills that don’t disolve in vinegar will not disolve in your MUCH stronger stomach acid. Also, I wonder what pickels are doing in my stomach seeing as they are stored in vinegar. They must come out whole as well.

    Looks like Dr. Oz is in the business of dissuading vitamin use in a very well guised fashion, then flip flopping and saying they are good (wolf in sheep’s clothing). His favorite vitamins I have learned are Multi’s Omega 3’s and Vitamin D – two of which, more often than not – come in a gel cap some of which apparently don’t dissolve in his inaccurate test.

    There are a few things missing in his poorly designed and misleading mock test: Like the fact that Hydrochloric acid is approx. 25 times stronger than vinegar. The other missing factors includes “a variety of key digestive juices, powerful enzymes and bile as highlighted by the following excerpt from the National Digestive Diseases Information Clearinghouse :

    “Several factors affect emptying of the stomach, including the kind of food and the degree of muscle action of the emptying stomach and the small intestine. Carbohydrates, for example, spend the least amount of time in the stomach, while protein stays in the stomach longer, and fats the longest. As the food dissolves into the juices from the pancreas, liver, and intestine, the contents of the intestine are mixed and pushed forward to allow further digestion.
    Finally, the digested nutrients are absorbed through the intestinal walls and transported throughout the body.

    Production of Digestive Juices

    The digestive glands that act first are in the mouth—the salivary glands. Saliva produced by these glands contains an enzyme that begins to digest the starch from food into smaller molecules. An enzyme is a substance that speeds up chemical reactions in the body.

    The next set of digestive glands is in the stomach lining. They produce stomach acid and an enzyme that digests protein. A thick mucus layer coats the mucosa and helps keep the acidic digestive juice from dissolving the tissue of the stomach itself. In most people, the stomach mucosa is able to resist the juice, although food and other tissues of the body cannot.

    After the stomach empties the food and juice mixture into the small intestine, the juices of two other digestive organs mix with the food. One of these organs, the pancreas, produces a juice that contains a wide array of enzymes to break down the carbohydrate, fat, and protein in food. Other enzymes that are active in the process come from glands in the wall of the intestine.

    The second organ, the liver, produces yet another digestive juice—bile. Bile is stored between meals in the gallbladder. At mealtime, it is squeezed out of the gallbladder, through the bile ducts, and into the intestine to mix with the fat in food. The bile acids dissolve fat into the watery contents of the intestine, much like detergents that dissolve grease from a frying pan. After fat is dissolved, it is digested by enzymes from the pancreas and the lining of the intestine.”

    Looks like Dr. Oz should have devoted 10 minutes to basic research before he did his puppet show.

    This is silly, not only is the pH of vinegar much higher than that that of your stomach, you aren’t utilizing proteins and enzymes found in our stomachs that digest. Further, our gastric systems are comprised of muscle, so unless you put your warmed vinegar in a bag and agitated it this would NOT be replicating the action of a stomach at all. You might as well throw a pill in a glass of water and stare at it for all the good you’re doing.

    @Dee: “Dear Widemouth…Why does Dr. Oz have a show and you don’t?”

    Seems to me that being friends with Oprah has something to do with it.
