请考虑购买标准量勺（如果你没有），这将是液体和粉末补充剂必备物品。

该粉剂只由碳酸钙和柠檬酸钙组成，无其它添加。它易于与食物或饮料混合，可用来适温烘烤。也能适宜参与制成曲奇、松饼、松糕和其它烘焙食物。但是，用于烘烤可能会损失维生素D。
为什么我要补充钙？
钙是我们身体每天都需要的必需矿物质。钙在我们的身体起重要作用，如果缺少会出现一系列健康问题。首先，钙是骨骼和牙齿的主要成分。98%以上的钙储存在此。其它的钙则维持心脏功能、循环、神经功能及肌肉协调。
如果饮食营养不良而造成钙缺乏，身体会从骨骼中"抢劫" 钙来补充不足。一旦发生这种情况，会出现低峰骨质----生长成熟期出现低含量骨质。低峰骨质可能会引起骨质疏松症----骨骼瘦弱易脆。美国有超过两千五百万人患有此病，这是多原因的疾病，与种族、性别、遗传、身体结构、饮食、运动程度、和生活方式有关。过分烟酒亦是骨质疏松的危险因素。人的一生中应摄取适量钙质，建立并维持良好的骨骼健康，优化骨质，减低骨质疏松症的风险。钙摄入量若超过日推荐值200%，即2000毫克，则毫无意义。
什么年龄吸收钙最要紧？
一句话，所有年龄的人都要吸取钙。骨骼正在生长的婴儿、儿童发育期、分娩期、要保持骨骼健康强壮的成年期，钙都不容或缺。
我不能从饮食中获得足够的钙吗？
婴儿奶粉及一些儿童食物与母乳一样富含钙质，因此婴幼儿可能能够从饮食中获得足够钙。一旦脱离这些产品，就难以获得足量钙。国家医学科学研究院认为，从四岁到成年，钙的最佳摄入参考是每天800毫克至1200毫克。要从饮食中获得这些钙，一个人一天要吃二至三份奶制品，好几份蛋白质，蔬菜，谷物，水果。多数人很难做到。
有的人对乳制品，乳糖，及奶类蛋白质产生敏感，他们就更难从饮食中获得足量钙。
是什么影响我从食物中吸收钙？
含植酸的多纤食物和植物食物与咖啡因一样不利钙的吸收。过量脂肪，高盐，汽水亦有负面影响。
服食钙最好一天中分开几次而不要一次吃掉所有的量。研究显示一次吃太多量，吸收反而降低。
维生素D提高钙的吸收，因此要确保从你的饮食摄入足量维生素D。维生素D储存在身体里，因此在补充钙的同时不必补充维生素D，虽然很多钙补充剂都含有小量维生素D，仅起预防作用而已。牛奶和谷物富含维生素D，阳光也制造维生素D，但没有在阳光下活动的老人和营养不良者仍很易缺乏维生素D。
我要服食何种钙补充剂？
市面上有许多优质钙补充剂。最普遍的钙源是碳酸钙和柠檬酸钙，碳酸钙尤其量大。这二者都很好吸收。新英格兰医学期刊(1987) 报导这二种形式的钙与牛奶中的钙有相类似的吸收模式，其后的一系列研究也证明了这一结论。
碳酸钙与食物一起摄入吸收最佳。胃酸缺乏者似乎对柠檬酸钙吸收更佳，但当碳酸钙与食物一起摄入，这二者的吸收区别并不大。
还有一种钙形式的吸收性能更具优势。它是尤他州Albion实验室生产的二甘氨酸螯合钙。
选择钙补充剂还有其它质量问题注意吗？
质量差的钙补充剂铅含量可能较高。美国药典(USP)和食品化学药典正在考虑补充剂的质量标准，他们发表的刊物铅的认受性是百万分之三(ppm)，这也是食物药品管理局能接受的铅水平。大部分有信誉的公司均采用这些标准。要指出的是，几家提供优质医药级钙的铅含量远低于可接受标准的3ppm。
优质钙补充剂的另一个问题是成形后的分解标准。产品必须能在体内溶解以起作用。当你购买钙的时候，请向厂家查询钙的标准是否符合USP。
最后，当你想要购买某种钙补充剂时，仔细看看它的标签。所需要的钙是钙元素。标签上应该提供矿物钙的总量，而不是钙盐的量。例如，应标明是60毫克钙元素，而不是600毫克碳酸钙。如果一个产品提供600毫克碳酸钙，只有216毫克钙元素而已。若有疑问，请与厂家联系。钙不能有缺。
我可以多吃钙吗？
国家健康研究所和美国医学杂志似乎同意，大部分人每天摄取高达2000毫克仍是安全的。

Description
This is a hypoallergenic formulation of calcium powder with vitamin D that has been specially designed for individuals with special requirements and sensitivities.
The powder is an unflavored blend of calcium carbonate and calcium citrate with
no additives. It mixes easily in food or beverages and can be used in
baking at moderate temperatures. It has been successfully incorporated
into cookies, pancakes, muffins and other baked goods; however, some of the
vitamin D content may be lost if used in baking.
What is calcium and why might I need more?
Calcium is an essential mineral that your body needs every day. Calcium
plays a number of important roles in the body. A deficiency can cause
numerous adverse health issues. First, calcium is the major constituent
of bones and teeth. More than 98% of the body’s calcium is found in those
structures. In the rest of the body, calcium supports heart function,
circulation, nerve function and muscle tone.
If insufficient calcium results from poor dietary intake, the body can
"rob" calcium from the bones to make up the shortage. When this
happens, low peak bone mass can result; this means that there will be a low
amount of bone mass present at maturity. Low peak bone mass can be a
contributing factor to the development of a potentially crippling disease of
weak, thin, fragile bones called osteoporosis. More than 25 million
people in the United States
have this multifactorial disease, which is also affected by race, sex,
heredity, body stature, diet
, exercise level and
lifestyle. Excess alcohol consumption and smoking are also considered
risk factors in osteoporosis. Building and maintaining good bone health
through adequate calcium intake throughout life is linked to a reduced risk of
osteoporosis by optimizing bone mass. Calcium intake exceeding 200% of
the recommended daily intake (2000 mg) has no further known benefit.
At what age is calcium intake important?
Very simply, at all ages. Calcium is important to infant development,
childhood development when bones are growing, during childbearing and during
adulthood to keep bones healthy and strong.
Can’t I get enough calcium from my diet?
Infant formulas and some baby foods are rich in calcium, as is breast milk, so
babies and infants probably get enough. Once off of those sources,
getting enough calcium becomes more difficult. It is generally recognized
by the Institutes of Medicine of the National Academy of Sciences that from
ages four through adult, optimal calcium Dietary Reference Intakes for good
health range from 800 to 1200 mg daily. To get that from the diet requires that an individual
ingest two to three servings of dairy products per day, plus several servings
of protein, vegetables, grains and fruits. This is difficult for many
people.
Many individuals are sensitive to dairy products, casein, lactose or other
dairy proteins. These individuals find it very challenging to obtain enough
dietary calcium.
What affects calcium absorption from my diet?
Fiber-rich foods and plant foods containing phytic acid can negatively affect
the absorption of calcium, as can caffeine. Excess fat, salt and soft
drinks also have a negative effect.
It is better to spread calcium intake out over the day instead of taking it all
at once. Studies show that when too much calcium is in the body at once,
absorption is diminished.
Vitamin D increases the absorption of calcium, so it is important to make sure
your diet contains sufficient amounts of
that nutrient. Vitamin D is stored in the body, so it is not necessary to
consume the vitamin D at the same time as the calcium; however, many calcium
supplements contain small amounts of vitamin D as a precautionary
measure. Since milk and cereals are usually fortified with vitamin D and
sunlight also provides this, older adults without sunlight exposure and with
poor diets are most at risk to be deficient in vitamin D.
What kind of calcium supplement should I take?
There are many excellent calcium supplements available on the market.
Calcium carbonate and calcium citrate are the most popular sources, with
calcium carbonate being by far the most abundant. Both calcium carbonate
and calcium citrate are excellent sources and are well-absorbed. The New
England Journal of Medicine (1987) reported that these forms of calcium had
similar absorption profiles to the calcium found in milk, and these results
have been confirmed in subsequent studies.
Calcium carbonate is best absorbed when taken with food. Individuals with
the condition achlorhydria (missing stomach acid) seem to absorb calcium
citrate better, though the difference is minimized when calcium carbonate is
taken with food.
There is one form of calcium that has shown some advantages in absorption
properties. The form is known as calcium bis-glycinate chelate, which is
produced by Albion® Laboratories Inc., of Clearfield,
Utah. See a discussion of
this form of calcium under Kirkman's Bio-Max calcium product.
What other quality issues do I need to be concerned about when choosing
calcium supplements?
Poor quality calcium supplements may contain a higher lead content than is
desirable. The United States Pharmacopoeia (USP) and the Food Chemicals Codex
are considered standards for quality materials used in supplements. The
lead tolerance in these publications is three parts per million (ppm), an
acceptable level to the Food and Drug Administration. Most reputable
companies have adopted these standards. It can also be pointed out that
several high-quality pharmaceutical grades of calcium are also available that
have lead levels far below the 3 ppm accepted standard.
Another issue in quality calcium supplements is disintegration and dissolution
standards of the dosage form. A product must dissolve in the body to do
any good. Check with your manufacturer to ensure that its calcium
products meet USP standards.
Finally, look carefully at the label of the calcium supplement you are thinking
about buying. The requirements for calcium intake refer to elemental
calcium. Your supplement should be supplying the total amount of the
mineral calcium, not an amount of the calcium salt. For example, a
supplement should be supplying 600 mg of elemental calcium, not 600 mg of
calcium carbonate. If a supplement supplied 600 mg of calcium carbonate,
it would only be providing 216 mg of elemental calcium. If in doubt, call
the manufacturer. Calcium is too important to your health to have a
deficiency.
Can I take too much calcium?
The National Institute of Health and the Journal of the American Medical
Association seem to agree that most people can safely consume up to 2000 mg per
day of calcium.
