ミネラル配合マルチビタミンについてのFAQ
（よくある質問とその答え）
| １．ミネラル配合マルチビタミンとは何ですか？
|
| |
必須ビタミンとミネラル、トレースミネラル、
薬用ハーブをブレンドしたものです。
成分表は上の英文を参考にしてください。 |
|
２．ビタミンとミネラルは体内でどのように作用するのですか？
|
| |
答えはたくさんあります。
以下にいくつかの例を挙げます。
ビタミンEの第一の役割は、活性酸素を攻撃するという意味を持つ抗酸化剤であるようにおもわれます。
毎日、活性酸素、つまり対になった電子をもたない酸素分子は、細胞や組織を破壊し、すくなくとも１００種もの変性状態を作り出しています。
多くの場合、これらの健康状態は癌、心臓病、アルツハイマー症、いくつかの関節炎等の老化現象の進行と関連しています。
強力なビタミンEなどの抗酸化剤は活性酸素を中和する電子を供給します。
（*1）
抗酸化剤としての働きに加え、ビタミンEは赤血球の形成などとともに普通の発育や成長を促進させる役割もあります。
ビタミンCは、アスコビック酸としてもしられていますが、昔から壊血病を予防するビタミンとして、また風邪の治療に使われるビタミンとして知られています。
現在ビタミンCは色々な症状に効果を発揮する抗酸化剤として知られています。
11，000人以上のアメリカ人の心臓病患者を対象とした研究の結果、ビタミンCを補足した患者の死亡率は、ビタミンCを補足しなかった患者に比べ，42％も少なかったことがわかりました。
癌では38％、糖尿病その他の病気では20％死亡率が低くなりました。
さらに、ビタミンCはエイズ治療にも有効であるらしいとも言われています。

| ３．なぜ、ビタミンとミネラルを摂取する必要があるのですか？
|
| |
ビタミンとミネラルは健康を維持する上でもっとも基本的なものであり、しかも充分に摂取することが極めて難しいものです。
栄養学的研究によれば、ビタミンCが不足している人は全体の26％、ビタミンAでは31％、カルシウムでは42％、マグネシウムでは39％、
鉄分では32％、ビタミンB6では51％、ビタミンB1では17％、 ビタミンB2では12％、ビタミンB12では15％の人が不足しているという報告がなされています。（*7）
別の研究によると、若い女性のスポーツ選手は、ビタミンB群、カルシウム、亜鉛、鉄分、マグネシウムなどの成分が不足しているそうです。（*8）
思春期の女性の場合、約半数がビタミンB６のRDA値の3分の２も確保できていなく、彼女達の20％は適量と不足の境にいますが、13％は完全に不足しているそうです。（*9）
成人女性の場合、72％はRDA値の70％以下しか亜鉛、葉酸しか摂取しておらず、30％はRDA値の70％のカルシウム、鉄分、
40％はRDA値の70％のマグネシウム、ビタミンB6、10しかとれていないそうです。（*10）
|
| ４．RDA値を摂取していれば充分ですか？
|
| |
RDAは人口集団において、壊血病などの重度欠乏症を減らす目的で作られました。
そのためRDA値は個人に対する最適摂取量を定めていません。
さらに、ビタミン、ミネラル等の摂取の必要性をより高めるであろう生活スタイルや環境などの要素は充分に考慮されていません。
たとえば、喫煙者はタバコを吸わない人の2倍はビタミンCを摂取する必要があります。（*11） |
| ５．どれくらい服用すればよいのですか？ |
| |
毎日の栄養補助食品として、一日に1〜3錠をできるだけ食後に飲んでください。 |

2. What are vitamins and minerals doing in my body?
|
| |
The answer is a lot, the following are a few specific examples.
Vitamin E's primary role seems to be as an antioxidant, which means that it fights free
radicals. Every day free radicals, molecules with unpaired electrons, work to break down
your cells and tissues, contributing to at least 100 degenerative health conditions. Many
of these health conditions are associated with the acceleration of the aging process
including: cancer, heart disease, Alzheimer's disease, and arthritis to name a few.
Antioxidants, such as the powerful vitamin E, provide the electrons which neutralize free
radicals. (*1)
In addition to its role as an antioxidant, vitamin E also promotes normal growth and
development as well as normal red-blood cell formation. Vitamin C, also known as
ascorbic acid, has long been known as the vitamin that prevents scurvy and aids in the
treatment of colds.
It is now known that vitamin C is a potent antioxidant that may be of benefit in the
treatment of many conditions. The results of a study on supplementation of vitamin C,
involving more than 11,000 Americans, showed a 42% less mortality rate from cardiovascular
disease for those who supplemented with vitamin C. The cancer death rate was reduced by
38% and diabetes and other diseases were reduced by 20%. In addition, there is evidence
suggesting that vitamin C may be of benefit to AIDS patients.(*2)
Selenium, a trace element, is a component in glutathione peroxidase, an antioxidant
enzyme, which prevents oxidative damage to the cells.(*3)
It is also important in DNA repair and immune function activation. Studies in China have
shown that selenium may be of benefit in cases of cancer. Researchers from the National
Cancer Institute and the Chinese Academy of Medical Sciences state that supplementation of
selenium with vitamins can lead to lower rates of cancer. Selenium may also be of benefit
in cases of asthma, heart disease, and hypertension during pregnancy.
Calcium is a builder; it gives bones and teeth their strength and rigidity, and also helps
nerves to function properly. Calcium is vitally important for growth and development.
During the last trimester of pregnancy, between 200 and 300 mg. of calcium is deposited in
the babies skeleton every day. If we have adequate levels of calcium in our bodies the
chances of developing crippling bone diseases is greatly reduced. In fact calcium can help
to inhibit, halt, or even reverse osteoporosis.
Magnesium plays an extremely important role in regulating cell metabolism and growth.
Almost all of the chemical reactions the cell must carry out depend on magnesium.(*4)
A correct balance of calcium and magnesium is essential for the heart and skeletal muscles
to function properly.
Green Tea Extract is made from the leaves of the tea plant, Camellia sinensis. It has been
used for thousands of years in Asia, as a beverage and medicine. Green tea extract is a
bioflavonoid-rich, potent extract which is of great benefit as a free-radical fighter. It
helps lower high blood pressure, reduces platelet aggregation, and inhibits bacteria that
causes food poisoning. In addition, it helps block the cancer promoting actions of
carcinogens.(*5,6) |

3．Why should I take a vitamin and mineral supplement?
|
| |
Because vitamins and minerals are absolutely essential for good health and
there is a very good chance that you are not getting enough of either. Large scale
nutritional surveys have found that 26% of people are deficient in vitamin C, 31% in
vitamin A, 42% in calcium, 39% in magnesium, 32% in iron, 51% in B6, 17% in thiamine, 12%
in riboflavin, and 15% in B12. (*7)
One study showed that young female athletes were deficient in several nutrients including:
most B vitamins, calcium, zinc, iron, and magnesium.(*8)
A study involving the diets of adolescent women found that half of them were failing to
supply two-thirds of the RDA for the important vitamin B6. Further tests showed that 20%
of these young women were on the borderline between adequacy and deficiency for B6, while
13% had crossed the line into deficiency.(*9)
Yet another test reveled that the diets of 72% of the adult women studied provided less
than 70% of the RDA for zinc and folic acid; 30% had diets that did not even provide 70%
of the RDA for calcium and iron; and 40% had diets that gave them less than 70% of the RDA
for magnesium and B6.(*10) |
|
4．Are the RDAs enough?
|
| |
The RDA was established to reduce the rates of severe deficiency diseases, such as scurvy,
in population groups; they do not define "optimal" intake for an individual. In
addition, the RDA does not adequately address factors such as life-style and environment,
which can increase the necessary amounts of vitamins and minerals. For example, smokers
require twice as much vitamin C as nonsmokers.(*11) |
|
5. How much should I take?
|
| |
As a dietary supplement you should take one to three tablets daily,
preferably after meals. |
