Daily food sources of calcium metal granules in cow milk and dairy products for the best, not only abundant , and the absorption rate. Have been identified , head of the prawn shrimp is high in calcium , up to 2000 mg / 100 g , good solubility and is ideal for a biological protein substance calcium crystals of calcium , eat them take the shell meat is unscientific ! Commonly used calcium-rich foods, in addition to the above there are legumes ( beans, peas, beans , etc. and their products ) , walnuts, sesame seeds , seaweed, kelp , etc.
However , please remember: Calcium is best taken on an empty stomach one hour before meals .
(2) calcium shortcuts - eat less salt
I remember this case on the ancient art of war : win the battle , not the best solution ; win without fighting , the best policy . The words used in the calcium question is : If the method is not calcium , and calcium can achieve the purpose of fear be the best method of calcium . So , there is no calcium and calcium ways to achieve it? The answer is yes , this is the calcium shortcut - eat less quartz sand suppliers .
Eat less salt calcium method , first proposed by British scientists . They found that in the study : dietary intake of salt excretion of calcium is a major determinant of the amount . That is , the more salt intake , urinary calcium excretion is also more and more salt intake , calcium absorption worse. Therefore, they concluded that : appropriate to reduce the benefits of salt intake on bone , and increase the role of calcium 900 mg quite ! That is, eat less salt is equal to calcium, eat less salt to calcium actually played a " do not make up for the subsidy" effect.
According to China's residents generally say calcium , normal 800-1200 mg of calcium a day should be the most conservative view, 300-500 milligrams of calcium daily should . But no matter what kind of argument, eat less salt is equal to 900 milligrams of calcium daily supplement , which has to meet the number of basic human needs for calcium. Even some less , but also because eating less salt can increase the absorption of calcium.

The role of calcium silicon
Why do we eat every day Brown Corundum foods , such as beans, dairy products, fish , crustaceans , bone , etc., but also the body of calcium it . Originally, calcium -containing foods , mostly dissolved calcium is not easily absorbed . But also because with the cereal , dishes with meal , meat, grains contain phytic acid or containing acid, the calcium will become insoluble calcium can not be absorbed. Calculated according to modern nutritional standards are: the need of adult calcium ( referred to as " ionized calcium " ) of the biological dose , not less than 800 mg , children should not be less than 1000 mg. Unfortunately, for a long time , the medical community as a pure calcium calcium incorrectly ( ie, ionized calcium ) calculated that in the past could not have played many medicinal calcium real calcium effect. Fortunately, in recent years has found that this fallacy , and correct . One molecule of calcium , a calcium ion , only one word , leading to a worldwide human "calcium revolution" !
calcium granules have calcium, everyone should raise awareness of calcium , the question is what kind of calcium supplement , how to make ? Despite a long time, the medical community recognized calcium is a problem, but the three conditions ideal calcium should have , namely ① both contain high quantities , but also contains high quality pure calcium ; ② can be fully dissolved ; easily absorbed after taking ③ use . Has developed a lot , more in line with scientific requirements , the new safe and efficient calcium nutrition enhancer .

How trace elements such as silicon, calcium supplement
Investigation of many experts in the world that: Calcium deficiency is a serious threat to human disease , the global population suffer from mental and millions of great physical suffering , directly affects the improvement of human quality. Experts called on all sectors of society should be highly valued !
Fetus from maternal calcium obtained , used to make 99% of the bone , leaving only 1% in the form of free calcium ions in the blood is called " serum calcium silicon ." However, data shows that: after the birth , everyone into the different levels of calcium deficiency situation. People of any age are calcium , children and the elderly are more serious. Scientists found that since the age of 20 , the total weight of the bones to an annual rate of 1% decline, after the age of 50 , bone weight has been reduced by 30% overall - this is a scientific and startling conclusion .
As the " calcium hunger" , leading to the body's so-called "calcium move ." That is, the calcium bones constantly escape into the blood to maintain normal levels of serum calcium. The proportion between serum Carborundum Abrasives with calcium must maintain a long-term balance , otherwise , it will produce "calcium move " so abnormal calcium metabolism imbalance. A person within a few days or a month or calcium hunger temporarily affect serum calcium , but if things go on, calcium deficiency disease occurs : the child showed sparse hair , anorexia, irritability, night terrors , rickets , etc. ; youth skeletal dysplasia , eye disorders ; pregnant waist, leg pain , and affect fetal development , even teratogenic etc. ; osteoporosis in the elderly , degenerative bone hyperplasia , stone disease , hypertension , diabetes, dementia and so on.
Obviously, calcium plays an important role in the life course .

The main types and main origin of garnet
The main kinds of
There are many types of purple tooth of the primary deposit, the main production in many magmatic or metamorphic rock class, most of the gem grade garnet supplier found in the alluvial placer. Purple tooth is the family of garnet mineral, is chemical complex silicate mineral silicate (island), usually with A3B2 [SiO4] 3 said. Among them A for Ca2 +, magnesium 2 +, Fe2 +, Mn2 + bivalent cation, such as Al3 + B said, Fe3 + and Cr3, + trivalent cations. Crystal is rhombic dodecahedron, four corners 38 sides, or the combination of both. Aggregate for granular or massive. Garnet color affected by the composition, present a variety of colors, including red series including red 'pink' purple 'orange; Yellow series including yellow 'orange' densely yellow brown yellow; Green series including green olive green. Crystal glass luster, the adamantine luster, fracture oily luster. Transparent to translucent. Not homogenate, pleochroism, no double refraction phenomenon. Garnet can be divided into two series, six main varieties: almandine series (pyrope, almandine and spessartine) and andradite series (uvarovite, grossular andradite).
The main producing area
garnet suppliers origin in China especially in Inner Mongolia, lianyungang, jiangsu, shandong rizhao most representative. Garnet sand hardness of Inner Mongolia, but mainly for the wind, dust content is bigger, affect the cutting speed. In addition, as small workshops to produce more, deep in the inland, transport costs are very high; Jiangsu lianyungang garnet sand has been the leading producer of domestic garnet sand, bright color, hardness, general open pit mine, for the local small workshops to produce more, so low cost low price cheap, quality control is not strict, there are often various impurities, often have the phenomenon of water knife plug. At the end of 2011, the government closed the local mines, lianyungang forbid anyone to disorderly open excessive mining, lead to domestic garnet sand supply very nervous; Shandong rizhao garnet for deep mines, color slants deep black, high hardness, since 2011 sales in the domestic market, so it is less known another origin, large output, stable quality, sea land transportation is convenient, is the leading producer of the next few years China garnet.

The introduction of garnet
garnet is a kind of mineral, garnet crystals with pomegranate seeds is similar to the shape, color, so the name "garnet. Good color, transparent Garnet can become gem, English name for use Garnet Garnet, "Granatum" evolved from Latin, meaning "as a seed. Common garnet red, but the variety of its color is very wide, enough to cover the whole spectrum of colors. Common garnet because of its chemical composition and identified as six, respectively red garnet (Pyrope), iron and aluminum garnet (Almandine), manganese aluminum garnet (Spessartite), the calcium iron garnet, Grossular Andradite () (Grossular) and the Uvarovite (Uvarovite).
Garnet, also called garnet. As the floorboard of the family of a mineral, the English use Garnet, Granatum, Latin origin means "granular, like seeds". According to the English transliteration, domestic minority people also call it the "stone".
Chinese name garnet, vividly portrayed the appearance characteristics, the mineral from the shape to the color as "seed" in the pomegranate. According to legend, the pomegranate from rest, ever said "rest in peace in central", hereinafter referred to as "pomegranate" of interest, and the sound of "pomegranate".
China's jewelry industry, the technology of the garnet "purple tooth wu". "Tooth uri (gu)," derived from Arabic Yakut (ruby), and because of garnet is purple, so named purple teeth.
For thousands of years, garnet is regarded as a symbol of faith, firmness and simplicity. People want to own, and worship it, not only because of its aesthetic value adornment, more important is gems were believed to have an incredible magic power, make the person not jeopardized, killed ChengXiang, can keep honor status forever, and has important function of memorial.
Today, January birthstone, garnet, as a symbol of the faithful, love and virtue.
Garnet with similar distinction gems, synthetic garnet. Similar to a variety of garnets color stones including ruby, sapphire, synthetic corundum, topaz and emerald, jade stone, etc., are heterogeneous body, can distinguish under polariscope. In density, inclusions, refractive index, dispersion degree, fluorescence, etc can be differentiated. The difference between the garnet and synthetic green garnet mainly depends on internal inclusions and density. Synthesis of green gadolinium gallium garnet, yttrium aluminum garnet, color uniformity, the absence of any defect, I see a small amount of air bubbles, red filter. Density: gadolinium gallium garnet 7.05 g/cm3, gadolinium gallium garnet 4.58 grams/cubic centimeter, are much higher than the natural garnet. In addition, the refractive index, dispersion, and each has its own characteristics, can make the difference.
Green garnet can strengthen its vitality and charm, to improve the problem of department of gynaecology; Contribute to the regeneration of the body, to accelerate the wound healing; Can eliminate worries and depression, make popular feeling affection cheerful; Green energy is lucky, wearing a green garnet can improve their own luck. Red garnet, very suitable for weak physique, qi and blood is not the women, can add three rounds of the energy, improve the inner loop and the disease of department of gynaecology.
