Nature's Life - Superabsorbeze Calcium Magnesium Liquid Fresh Orange - 16 oz.
Nature's Life Superabsorbeze Calcium Magnesium Liquid Fresh Orange is
pre-acidified (pH 4.0) to ensure maximum absorption of the essential
minerals. It is an excellent way to supplement a healthful diet with
additional calcium; especially good for children, for those interested
in an alternative to tablets or capsules and for those looking for a
sucrose-free, dairy-free, more easily digested calcium supplement.
Regular exercise and a healthful diet or dietary supplements
providing enough calcium help women maintain good bone health. Teen
through middle-aged women, and elderly men and women, may reduce their
risk of osteoporosis by adequate calcium intake which slows the rate of
bone loss. Calcium maintains healthy bones better when taken with other
minerals and vitamins. Calcium also supports the normal function of a
healthy cardiovascular system.
Nature’s Life Calcium Supplements
Nature’s Life offers a wide variety of calcium-rich dietary supplements in tablet, capsule and liquid form to help:
- Build strong, dense bones.
- Aid in the development and maintenance of healthy teeth.
- Support normal function of the cardiovascular system.
- Support a healthy pregnancy.
Calcium is the most abundant mineral in the human body. Of the two to
three pounds of calcium in the average body, 99 percent is stored in
the bones and teeth. The remaining one percent plays a crucial role in
muscle contraction, blood clotting, regulation of blood pressure, nerve
transmission and other body processes.
Building Strong Bones
degenerative bone disease caused by long-term loss of calcium from the
bones, affects approximately 28 million Americans. The most common
symptoms of osteoporosis are brittle bones in the hip joint, or spine.
Osteoporosis can affect anyone, but for every man who develops
osteoporosis, eight women develop the bone disease. The risk of
osteoporosis is higher in Caucasian and Asian women. Besides age, many
lifestyle choices can lead to bone loss, such as smoking, drinking
caffeinated beverages and lack of exercise.
The importance of calcium in building and maintaining strong bones
and teeth is probably its most beneficial role. A healthy skeleton is
what allows us to stand upright and provides a strong foundation for the
muscles that give us movement.
Bones are in a constant state of flux. In a process known as
modeling, minerals contained in bones are reabsorbed into the body and a
new supply of minerals then reforms the bones. A constant supply of
nutrients, including calcium, are needed for this modeling process of
Calcium is bound within the bone matrix, but can be moved in and out
of the bones if blood levels of calcium drop. Conversely, if calcium
blood levels get too high, the bones absorb a portion of the excess.
This allows blood calcium levels to remain very stable.
Preventing or slowing bone loss is considered a crucial part of
avoiding osteoporosis. Adequate calcium during childhood and the teenage
years is important for building strong, dense bones. During the middle
years of life, optimal calcium intake slows the natural loss of calcium
from the bones. And in later years, especially for women after
menopause, calcium intake can inhibit the rapid bone loss common to this
stage of life. Calcium is more effective in maintaining healthy bones
when used with other minerals, such as magnesium, copper, manganese and
zinc. These trace elements are essential in bone metabolism.
Calcium and the Cardiovascular System
Calcium is a
crucial element in the functioning of the cardiovascular system.
Optimal calcium intake helps maintain normal blood levels of total
cholesterol and low-density lipoprotein (LDL-the “bad” cholesterol).
Calcium also plays a role in blood pressure regulation. When the calcium
intakes of adults are compared to their blood pressure, those with
higher calcium intakes are more likely to have healthier blood pressure.
Pregnancy: A Special Time for Calcium
requirements increase during pregnancy and lactation since the mother
needs nutrients for herself, as well as for her baby. In response to
this higher need, the gastrointestinal tract increases its absorption of
calcium, but dietary intake should increase as well.
High blood pressure, fluid retention and other similar conditions
occur in approximately one in ten pregnancies. The health of the mother
and baby can be seriously compromised when these conditions continue
unchecked. According to research, pregnant women with a high calcium
diet (2 grams daily), compared to pregnant women with a lower calcium
diet (640 mg daily), are more likely to maintain normal blood pressure
during their pregnancy. However, supplemental calcium intake during
pregnancy should be limited to 1,500 mg daily, since higher levels can
increase the risk of kidney stones, (another condition of increasing
incidence during pregnancy).
Other research suggests that pregnant women who take calcium
supplements are more likely to have a full-term delivery. A preliminary
study of pregnant teen-agers, a group at higher risk for pre-term
deliveries, showed that a daily 1,500 mg calcium supplement helped
normalize blood pressure and decreased the likelihood of premature
birth, without leading to any adverse side effects. Some women
experience an increase of blood pressure during pregnancy, however,
women taking calcium supplements during pregnancy are 36% less likely to
experience abnormal blood pressure.
The typical American diet
contains several nutrients and compounds which adversely affect calcium
levels in the body. Most Americans consume two to three times the
necessary daily requirement for protein. Some researchers even speculate
that excessive protein, rather than inadequate calcium, is a more
significant contributor to loss of bone density. Weight-bearing exercise
helps maintain strong bones and the lack of exercise leads to rapid
calcium loss from bones.
The typical American diet is also high in phosphorus from soft drinks
and other processed foods. A higher intake of calcium may be necessary
to compensate for a high-protein or high-phosphorus diet. Phytonutrients
called oxalates and phytates found in some grains and vegetables reduce
the bioavailability of calcium. In addition, frequent use of
aluminum-containing antacids can increase the loss of calcium.
Supplemental Calcium: Safety Considerations
Calcium is safe up to 2
grams per day, but toxic effects can develop when more than several
grams are taken daily. Symptoms of excessive calcium intake include:
nausea; deposition of calcium into the soft tissues, such as kidneys and
heart, and; impaired absorption of other minerals, such as iron and
zinc. These symptoms are temporary and are relieved simply by reducing
Individuals prone to developing calcium deposits in the kidneys have,
in the past, been advised to limit their calcium intake, but new
research suggests that the timing of calcium intake may be the real
issue. According to the Nurses’ Health Study, a diet containing plenty
of high-calcium foods actually decreases the risk of calcium deposits in
the kidneys. However, the women in this study with a high calcium
intake resulting from calcium supplements increased their risk.
The difference between dietary and supplemental calcium intake may be
related to oxalates (a phytonutrient that is a common constituent of
calcium deposits in the kidneys). When calcium is consumed at the same
time as a meal rich in oxalates, the calcium inhibits the absorption of
the oxalates. Calcium supplements are not always taken at the same time
as a meal containing oxalates, which may account for why supplemental
calcium did not protect against formation of calcium deposits in
kidneys. Rather than forego calcium supplements, the researchers suggest
that it is probably prudent to take calcium supplements with a meal,
particularly lunch or dinner—meals which tend to have high oxalate
Lead In Calcium-Making It Safe: Minute amounts of lead are naturally
present throughout the environment, including all foods and calcium
supplements. Excess lead exposure, however, is a concern since large
amounts of this naturally occurring mineral contribute to several health
problems, especially in young children.
The Good Manufacturing Practices (GMPs) at Nature’s Life ensure that
all of the calcium found in Nature’s Life supplements have very low, and
very safe, levels of lead (less than 1 ppm of lead or 1mcg/g; far less
than the Federal standard). The low levels of lead in our products is
demonstrated by the fact that the maximum amount of lead present in any
Nature’s Life calcium supplement is only 5% of the safe daily intake
level for pregnant women, who are the most sensitive and at-risk
individuals for lead exposure. Additionally, calcium actually inhibits
the absorption of lead. As calcium intake increases, blood levels of
lead have been reported to decrease.
Calcium’s Changing RDAs
change throughout life. Calcium needs are greatest during the times of
rapid growth and development: childhood, adolescence, pregnancy, and
lactation, as well as in later adult life to prevent excessive calcium
losses. For adolescents the Recommended Dietary Allowance (RDA) for
calcium ranges from 400 mg to 1,500 mg per day. According to the
National Institutes of Health Consensus Conference, optimal calcium
intake varies throughout life.
Age Optimal Calcium Intake
- birth - 6 months ..... 400 mg
- 6 months - 1 year ..... 600 mg
- 1 - 5 years ..... 800 mg
- 6 - 10 years ..... 800 - 1,200 mg
- 11 - 24 years ..... 1,200 - 1,500 mg
- 25 - 65 years ..... 1,000 mg
- 65+ years ..... 1,500 mg
- Pregnant and Nursing ..... 1,200 - 1,500 mg
- 25 - 50 years ..... 1,000 mg
- 50+ years ..... 1,000 - 1,500 mg
- 65+ years ..... 1,500 mg
Different Forms of Calcium
Like all minerals,
calcium is inorganic (not bound to carbon) and is usually bound to a
carbon-containing compound to ensure its absorption into the body.
Dietary supplements may contain several different forms of calcium. One
of the main differences found between various calcium forms is the
percentage of elemental calcium they provide. For instance, in the
popular carbonate form, calcium accounts for 40% of the compound calcium
The following examples show common forms of calcium compounds and the
percentage of elemental calcium in each. The greater the percentage of
elemental calcium, the smaller the amount needed to obtain the desired
amount of calcium.
Form of Calcium % Elemental Calcium
- Calcium (carbonate-purified)........ 40%
- Calcium (carbonate from oyster shell).......40%
- Calcium (bone meal)...... 32%
- Calcium (hydroxyapatite-veal bone meal)...... 32%
- Calcium (citrate).......24%
- Calcium (citrate/malate)......22%
- Calcium (dolomite)..... 21%
- Calcium (aspartate) 13% - 20%
- Calcium (ascorbate)... 10%
- Calcium (gluconate)..... 9%
Absorption of Calcium
The percentage of elemental
calcium is not the only difference between various forms of calcium;
the absorption of calcium from foods or supplement sources is another
factor to consider. Substantial research shows that supplemental calcium
carbonate is at least as bioavailable as the calcium in milk. Milk and
other dairy products are preferred sources of well-absorbed calcium.
Research also shows that calcium citrate/malate has better calcium
absorption than calcium carbonate.
Other studies indicate that calcium absorption from several different
supplement forms, including carbonate, acetate, lactate, gluconate, and
citrate forms, are not significantly different from one another.
Although the best absorbed form of calcium continues to be debated by
researchers, it is widely accepted that the best time to take calcium
supplements is with food.
