المكملات الغذائية هي منتجات تؤخذ عن طريق الفم وتحتوي على 'مكونات غذائية' والتي ممكن أن تكون فيتامين أو املاح معدنية، واعشاب، وأحماض أمينية او إنزيمات.

 

الكثير من الناس يعتقدون أن شيئا طبيعي (مواد عشبية) لن تكون ضارة لهم. في حين قد يكون هناك آثار جانبية خطيرة عند التداخلات ما بين المكملات الغذائية و الادوية ومن الممكن أن تهدد الحياة. ومثال ذلك استخدام الجينسنغ من قبل مرضى السكري، ولكنه قد يؤثر على قدرة مادة الوارفارين بمنع تخثر الدم.

إدارة الأغذية والعقاقير الامريكية FDA تشترط أن يكون مسماها مكملات غذائية بحيث لا يتم الخلط بينها وبين الغذاء أو الدواء. المكملات الغذائية هي مساعد ومكمل في النظام الغذائي الصحي، ولا تحل محل تناول مجموعة متنوعة من الأطعمة المتوازنة من حيث فوائدها للجسم.

أن هناك الكثير من الأدلة ان المكملات الغذائية تغطي حاجة الجسم من انخفاض مستوى بعض المواد الغذائية، وليس هناك أدلة عن فائدتها في منع أو علاج الأمراض

 

على المرء الانتباه الى خمسة حقائق في هذا الشان

1.     تولي صحتك بمعرفة ، ان الاجهزة الحكومية لا تتحقق من المكملات الغذائية قبل أن يتم تسويقها، والمعايير المتعلقة بتسويق المكملات الغذائية تختلف كثيرا عن المعايير المتعلقة بالعلاجات والأدوية (المواصفات والاثار الجانبية).  فمصانع المكملات الغذائية لا تحصل على موافقة ادارة الغذاء والدواء بانها امنة  قبل أن تباع للمستهلكين.

2.     تنبه دائماً لاحتمالات التلوث. وهذا أدى احيانا إلى عواقب وخيمة. فعلى سبيل المثال، بعض المنتجات كانت ملوثة بالرصاص والمبيدات الحشرية، وغيرها من المنتجات المعلن عنها انها 'عشبية' بينما كانت تحتوي على عقاقير طبية.

3.     حظرت إدارة الأغذية والعقاقير FDA على الشركات المصنعة ادعاء بان المكمل يعالج المرض. في النظام الجديد ، سمح بوصف المنتج كمكمل وقائي صحي ولكن ليس علاج للمرض. فعلى سبيل المثال: مسموح بعبارة 'قد يقلل من خطر الإصابة بأمراض القلب' ، وليس 'علاج لارتفاع ضغط الدم'

4.     المنتج العشبي اكنسيا Echinacea ؛ خضع للعديد من الاختبارات التي اظهرت عدم احتواءه على الإطلاق على كميات قابلة للقياس من العشبة.

5.     الانتباه ل 'أختام الموافقة'

 

دائماً تحدث إلى خبير الرعاية الصحية مثل الطبيب أو الصيدلاني. لا يجوز اعتبار هذه المنتجات 'بانها علاجات او أدوية'، ولا تنسى  اخبار الطبيب بانك تتناول هذه المكملات لدى القيام بالمراجعات الطبية.

 

 

Dietary supplement is a product taken by mouth that contains a “dietary ingredient,” which can be vitamin, mineral, herb, amino acid, enzyme or metabolite. The FDA requires it to be labeled as a dietary supplement so it is not confused with food or medicine. Dietary supplements are intended to “supplement” a healthy diet, not replace the balance of eating a variety of foods.

While there is a lot of evidence that dietary supplements help in preventing and treating nutrient deficiencies, there is much less evidence about their usefulness in preventing or treating other diseases.

.

 

There are five points you need to remember

1.Take charge of your health by being informed. Dietary supplements are not reviewed by the government before they are marketed. The standards for marketing supplements are very different from the standards for drugs/medications (prescription/OTC).  For example, manufacturers of a dietary supplement do not have to prove to the FDA that it is safe, or that it works, before it is sold to consumers.

 

 

 

2.  Always be aware of the potential for contamination. This has resulted in serious consequences. For example, some products have been contaminated with lead and pesticides, and other products advertised as “herbal” have contained prescription drugs.

 

3. The FDA also banned manufacturer claims that a supplement can treat a disease. In new regulations, a product may make health maintenance claims but not disease claims. For example: “May reduce the risk of heart disease” is allowed, but “treats high blood pressure” is not.

 

 4.The herbal product Echinacea; many that were tested contained no measurable amounts of the herb at all.

 

5. “Seals of approval” that you may want to look for when shopping for supplements.

 

 Many people think that something “natural” couldn’t be harmful to them. Yet, serious side effects and drug interactions can occur when taking dietary supplements, some of which can be life-threatening.

Examples:

1. aloe vera, fenugreek and vanadium many cause excessive bleeding during surgery or interact with anesthetics.

2. Other supplements may interfere with prescription medications.

3. Ginseng may be used to treat diabetes, but may interfere with the drug warfarin’s ability to prevent blood clotting.

4. St. John’s Wort, which people often take for depression, can interact with antidepressants, as well as many other prescription medications.

5. An example of a potentially life-threatening combination is: Coumadin (a prescription medicine) + Ginkgo biloba (an herbal supplement) + Aspirin(an OTC drug) + Vitamin E (a vitamin supplement)

Each one individually acts as a blood thinner. When taken together, they can increase your risk for internal bleeding.

 

The chances of herbs and drugs interacting are high

1. It may be necessary to stop taking these products at least 2-3 weeks before surgery to avoid potentially dangerous supplement/drug interactions, such as changes in heart rate, blood pressure and increased bleeding, that could adversely affect the outcome of your surgery.

2. All people are potentially at risk for negative side effects from herbal supplement use, but those at greatest risk are:

.              Children and elderly

•             Pregnant and breastfeeding women

•             Chronically ill (hypertension, heart disease, diabetes, kidney disease)

•             Those taking medications (prescription and OTC)

•             Those taking multiple herbs with similar effects

•             Those replacing or combining drugs with dietary supplements

 

Always talk to your doctor or health care provider. You may not consider these products “drugs” or “medications,” or you may just forget to mention them during your visits. Even if you think your health care provider might disapprove of your choices, you need to discuss supplement use with them. If you don’t, inappropriate supplement use can lead to dangerous circumstances. For example, you may experience a side effect of a dietary supplement that your doctor then attributes to another medication. Retailers in health food stores may seem knowledgeable, but they most likely do not have the medical background, or familiarity with your personal health, to recommend products. The same is true for retailers on the internet.
