Mineral supplement tablets

O A bottle of mineral supplement tablets contains 100 tablets and 200 mg of copper. The copper is found in the form of cupric oxide. What mass of cupric oxide is contained in each tablet ... 

Sales of Ca supplements alone were 875 million in the United States in 2002, and comprised 60% of all mineral supplement sales (Anonymous, 2004). In 2004, sales of Ca supplements increased by 9.3% (Uhland et ah, 2004), possibly to some extent in response to the Surgeon General s report on bone health that was issued that year. More recently in 2006, it was projected that dietary supplement sales in the United States would approach 5 billion (Anonymous, 2006). While Ca derived from a balanced diet is preferable, Ca supplements are a popular noncaloric alternative for increasing daily Ca intake. There are a vast number of oral Ca supplements available in the market place in the form of capsules, tablets, chewable tablets, effervescent tablets, liquids, powders, suspensions, wafers, and granules. However, not all Ca salts are equally soluble or bioavailable and the dose of Ca on the label of a supplement may not necessarily be reflective of the relative amount of available Ca once consumed. Furthermore, the same Ca salt may be more or less bioavailable depending on the production process and materials used to manufacture the supplement. 

Calcium carbonate is the least expensive source of calcium in supplements. Regardless of the form—carbonate, citrate, or gluconate— read the label to determine how much of the actual mineral each tablet provides. Happily, some manufacturers are now offering cal-dum/magnesium supplements, which I highly recommend. 

Like tablets, capsules are mainly used for dogs and cats, but there are some vitamin and mineral supplement capsules formulated for cattle. There are three main treatment areas using capsules as the dosage form nutraceuticals, vitamins and minerals, and antimicrobials. 

In mineral supplementation in humans the oral route is the most commonly used, the supplement being given as a tablet, capsule, solution or as a fortified food. Injections are usually reserved for those cases where the patient is unable to eat due to damage to the gastrointestinal tract Or other reason, e.g. in patients on total parenteral nutrition it may be difficult to maintain adequate levels of iron, and supplementation by intramuscular injections of iron, for example, as a sorbitol complex will often be required. In view of the importance of the oral route it is helpful to consider the more salient general aspects of gastrointestinal absorption.

Bone meal, which is nature s own formulation, is fresh, degreased, ground animal bone. It is used as a mineral supplement for both humans and animals, and as a source of calcium, phosphorus, and needed trace elements. For human use, it is available in both powder and tablet form. It is noteworthy that (1) bone meal never contains toxic levels of the essential trace elements, whereas these are sometimes exceeded in man-made mineral formulations and (2) bone meal trace elements rate high in biological availability, physical and chemical compatability, and storage life. 

About one-half of the United States population take some type of vitamin and mineral supplement. Many of these include iodine, usually about 100-150 pg (10) in the form of iodide. Tablets containing from 100-500 pg of iodine are available in some countries with borderline iodine deficiency, such as Germany. 

The primary use for dibasic calcium phosphate in pharmaceutical applications is as a tablet or capsule diluent. It is also used as an excipient for direct compression formulations of hard tablets requiring a good disintegrant and an effective lubricant. It has limited use as a mineral supplement for calcium replenishment. Diluents often comprise the bulk of the tablet formulation, with use levels between 40 to 90 % of the tablet weight. It has also foimd use as an adsorbent and as a thickening agent in creams and ointments. The pharmacopeial specifications for Dibasic Calcimn Phosphate USP are as follows ...

Dietary supplements are products taken by mouth that contain an ingredient intended to supplement the diet, such as vitamins, minerals, herbs or other botanicals, amino acids, and substances such as enzymes, organ tissues, and metabolites. Dietary supplements come in many forms, including extracts, concentrates, tablets, capsules, gel caps, liquids, and powders. They have special requirements for labeling. In the U.S., the Dietary Supplement Health and Education Act of 1994 states that dietary supplements are considered foods, not drugs. (Note that some dietary supplements are used in conventional medicine for example, folic acid... 

The label on a bottle of supplements lists all the vitamins and minerals the supplements contain. It also lists the form and source of each vitamin and mineral, and the amount of each. The form of a mineral is especially important to know because it affects the quantity your body can use. For example, a supplement may claim to contain 650 mg of calcium carbonate, CaC03, per tablet. This does not mean that there is 650 mg of calcium. The amount of actual calcium, or elemental calcium, in calcium carbonate is only 260 mg. Calcium carbonate has more elemental calcium than the same amount of calcium gluconate, which only has 58 mg for every 650 mg of the compound. Calcium gluconate may be easier for your body to absorb, however. 

The United States Congress passed the Dietary Supplement Health and Education Act (DSHEA) in 1994. It describes a dietary supplement as a product (other than tobacco) that (1) is intended to supplement the diet, (2) contains one or more dietary ingredients (including vitamins, minerals, herbs, other botanicals, amino acids, and other substances) or their constituents, (3) is intended to be taken orally as a pill, capsule, tablet, or liquid, and (4) is labeled as a dietary supplement on the front panel. This means that dietary supplements are regulated as foods within the meaning of the act and such products do not require pre-market notification or registration except for new dietary ingredients (NDIs). 

Selenium Some people supplement their diet with tablets that contain essential vitamins and minerals. These supplements may include a small amount of sodium selenate. Selenium also can be found in such foods as fish, eggs, and grains. Selenium works with vitamin E to prevent cell damage. It may help to inhibit the growth of cancer cells. However, in the case of nutrients, more is not always better. The locoweed plant shown in Figure 7-18 provides an example of this principle related to selenium. When a locoweed plant absorbs selenium from the soil, the concentration of selenium increases to a toxic level. Grazing animals that feed on locoweed can become quite ill. 

Find out how the daily values for vitamins and minerals are determined. Compare supplements to see whether they all contain the same minerals in the same quantities per tablet. In your report, suggest reasons for any variations you discover. 

A random sample of a supplement containing 12 minerals (metals) was analysed using ICP-OES for their concentrations. The elements are listed in Table 7.10 along with the approximate concentration of each element in the tablet. 

I Administration. Even under optimal conditions, all bisphosphonates are poorly absorbed (bioavailabihty = 1% to 5%). Bisphosphonates must be administered carefully to optimize the chnical benefit and minimize the risk of adverse G1 effects. Each oral tablet should be taken with at least 4 ounces of plain tap water (not coffee, juice, mineral water, or milk) at least 30 minutes before consuming any food or any other supplement or medication. The weekly oral solution needs to be taken with only 2 ounces of water. The patient should remain upright (either sitting or standing) for at least 30 minutes after bisphosphonate administration. When calcium and vitamin D dietary consumption are insufficient, supplementation is needed to ensme the beneficial effects of bisphosphonates. 

Both inorganic selenium and selenomethionine are also found in selenium supplements. The amounts in these supplements generally range from 10 to 25 pg/tablet (Goodman et al. 1990). A guide to vitamin and minerals recommends that not more than 200 pg selenium/day should be taken in any form (Hender 1990). 

In 1982 an application was received by the National Board of Health for an authorization to place table salt fortified with iodine on the market. As food policies were that vitamins and minerals should not be added to food without documentation of a need for this, no authorization was given. However, it was legal to add iodine (mostly 150 pg) to vitamin-plus-mineral tablets, and such supplements were (and are) taken by a considerable part of the population (Knudsen et aL, 2002d). 

Supplements. Vitamin C is the most widely taken dietary supplement. It is available in many forms including caplets, tablets, and capsules, drink mix packets, in multivitamin formulations, in multiple antioxidant formulations, as a chemically pure crystalline powder, timed release versions, and also including biofiavonoids, such as quercetin, hesperidin, and rutin. The use of vitamin C supplements with added bioflavonoids and, often, flavors and sweeteners, can be problematic at gram dosages, since those additives are not so well studied as vitamin C. In supplements, vitamin C most often comes in the form of various mineral ascorbates, as they are easier to absorb, more easily tolerated, and provide a source of several dietary minerals.
