Caffiene will interfere with the body abosorbing vitamins

[myrori 55]

Caffeine is a part of the Breakfast meal of many Americans. Many also take a Multivitamin supplement daily as a part of their morning routine. Not many people are aware that taking Vitamins at the same time as a cup of coffee or tea can interfere with the body’s absorption of many necessary nutrients.

Calcium

Caffeine causes Calcium to be excreted in the urine and feces. For every 150 mg of caffeine ingested, about the amount in one cup of coffee, 5 mg of calcium is lost. This effect occurs even hours after the consumption of caffeine. One study of postmenopausal women found that those who consumed more than 300 mg of caffeine lost more bone in the spine than women who consumed less.

Caffeine also inhibits the amount of calcium that is absorbed through the intestinal tract and depletes the amount retained by the bones. Studies have shown that women with high caffeine intake suffer more hip fractures than those who avoid caffeine or drink in moderation (1 to 2 cups per day).

Vitamin D

Caffeine inhibits Vitamin D receptors, which limit the amount that will be absorbed. Because Vitamin D is important in the absorption and use of calcium in building bone, this could also decrease bone mineral density, resulting in an increased risk for osteoporosis.

Iron

Caffeine interferes with the body’s absorption of Iron, which is necessary for red blood cell production. Drinking caffeine at the same time as an iron source can reduce absorption by up to 80%, according to the Nutrition Desk Reference. Any beverage containing caffeine should be separated from iron-containing foods or supplements by at least one hour.

B Vitamins

Caffeine has a mild diuretic effect, which increases urination. Water soluble vitamins, such as the B-vitamins, can be depleted as a result of the Fluid loss. In addition, it interferes with the metabolism of some B-vitamins, such as thiamine (vitamin B1). The one exception to this rule appears to be vitamin B12. Caffeine stimulates the production of stomach acid, which actually helps the body absorb B12.

Other Vitamins and Minerals

Caffeine may reduce the absorption of manganese, zinc and copper. It also increases the excretion of the minerals magnesium, potassium, sodium and phosphate. There is also evidence that caffeine interferes with the action of Vitamin A.< /p>

Sources of Caffeine

Coffee and tea are obvious sources of caffeine. Even decaffeinated versions contain a little residual caffeine. Other sources include soft drinks, chocolate, cocoa and some energy drinks. Some supplements and medications, such as those that promote wakefulness, along with pain relievers for headaches, contain caffeine anhydrous, which is the dried, powdery form of caffeine. Dietary supplements sometimes use a natural ingredient called guarana, which is another form of caffeine.

A cup of coffee or green tea a day is not likely to have a negative effect on your overall health. However, in excess, caffeine can cause nutrient deficiencies that can affect both health and quality of life. As with most dietary factors, moderation and balance are key in optimal nutrition intake.

What I learned and as it stated it caffeine has effects on the body long after you consume it. Since many Water soluble Vitamins can be flushed out of the body, caffeine having a diuretic effect on the body flushes the Water soluble vitamins out of our system. We are at risk for B12 definincy after surgery, b12 is destroyed by the gastric juices and needs to be taken sublingual to be absorbed,

Vitamin List

Vitamins are organic compounds found in foods and supplements that are vital for health. There are 14 official (and four unofficial) vitamins, all of which are essential for the proper functioning of our bodies.

We list all vitamins in the Vitamin list below. Each name links to information on the functions, deficiency symptoms, sources, and RDA of the vitamin :

Fat-Soluble Vitamins vs Water-Soluble Vitamins

Vitamins are usually classified according to whether they are fat soluble or water soluble. Vitamins A, D, E, K, and coq10 are fat soluble. The rest in the vitamin list above are water soluble.

Fat-soluble vitamins need the presence of fats and certain minerals to be absorbed by the digestive system, and are stored mainly in the liver and fatty tissues. Since they are stored in the body, they do not need to be consumed as regularly as water soluble vitamins, but pose greater risk of toxicity when taken in excess.

Water-soluble vitamins, on the other hand, are not stored in the body in significant amounts. They are normally readily excreted in urine, and so must be replenished into the body daily to avoid being depleted. They are also more easily lost in cooking.

What Vitamins Do

All the vitamins are essential for sustaining life. A deficiency in any vitamin causes disease symptoms that can only be cured by intake of the vitamin.

Each vitamin has a number of functions, some of which overlap with those of other vitamins. They are needed for normal growth, and play a part in the health of almost every organ. They enable many critical bio-chemical processes that take place in the body to sustain health and life.

Some play a role in absorption and metabolism of carbohydrates, Proteins, fats, and minerals. Others are important for brain function, resistance to infection, fertility, and proper functioning of the digestive system.

All have a role in fighting disease and aging. Vitamins have been tested to slow or reverse diseases such as cancer, dementia, osteoporosis, chronic fatigue syndrome, high blood pressure, atherosclerosis, heart diseases, and many others.

Vitamins must be taken with food to be absorbed by the body.
