In nutritional supplements, the Recommended Daily Allowance (RDA) set by the FDA is a guideline of the minimum amounts needed of a nutrient to stay healthy, but in numerous cases consuming more may be right for you. You ought to consult your doctor before taking larger quantities but in many cases, additional quantities may be needed to meet your personal requirements. Some medications and medical conditions can impact the body's ability to absorb and utilize vitamins and minerals and your doctor, nutritionist or other health care provider can advise you what amounts are best for you.

Keep in mind that if you take the right amounts of herbal or other supplements, there is a huge benefit in better health, more energy and greater mental clarity. The problem occurs only when vitamins and minerals are consumed in huge quantities, well over the published RDA. Since many nutritional supplements can appear as if they are candy to a child, always store your supplements in a safe place, out of reach of little hands.

One reason it is important to take the correct amounts of nutritional supplements is that over-supplementation can impact your health and even be hazardous. For instance, if you take high doses of Vitamin E, it won't be harmful but it can cause Vitamin K to be useless in clotting blood. If too much Vitamin E were taken in conjunction with blood thinners that various medical conditions require, significant dangers such as nose bleeds and injuries that can't be stopped from bleeding could potentially result. Since Vitamin E is stored in the body's fat, the impact can be cumulative when consuming too much of this necessary vitamin.

If excessive amounts of calcium are taken, the potential that formation of kidney stones can happen should be considered. Certain dietary issues such as high quantities of dairy products in the diet combined with large quantities of tea add to the possibility of painful stone formation.

Folic acid, when taking the right amounts of nutritional supplements, is very important. When too much is taken, Vitamin B12 deficiency can be masked. Amounts of niacin well in excess of the RDA can damage liver tissues as well as cause gastrointestinal upsets while the right dosage can be very important to good health and a sense of wellness.

Iron is another thing to be certain to take the right amount rather than too much. Some children have been poisoned by overdosing on iron and you should always make certain to purchase iron in a childproof package.

Selenium, when taking the right amounts, is very beneficial. Amounts over the RDA can result in vomiting, nervous system problems and even hair and nail loss. Lesions on the skin can appear. It is very important to take this very necessary supplement in recommended quantities.

Taking doses, much over the RDA, of Vitamin A has the potential to cause serious liver damage. It can even cause birth defects if huge amounts are taken during pregnancy, especially if this occurs during the first trimester of the pregnancy.

Nerve disorders and muscle weekends can result from taking far too much Vitamin B6 over a prolonged period of time. can cause diarrhea and urinary tract problems if taken in extremely large doses.

Taking the right amounts of nutritional supplements containing Vitamin D is important. The result of overdosing on Vitamin D can be irreversible kidney damage, potentially causing the need for dialysis for the rest of the person's lifetime. Heart and blood vessel damage can also occur when the dosage is much too high.

Zinc, a very necessary component for health, can reduce the body's ability to absorb copper and mute the body's immune system response. Immune system response is crucial for the body to be able to fight off illness and disease.

Any supplements, even if they only contain herbs and botanicals, have the potential to be dangerous if not used with caution. Again, if taken in the right amounts, they can be quite useful; just don't take higher quantities than recommended. Since there is no RDA for any of these products controlled by the FDA, never exceed the dosage on the label unless a qualified health care professional tells you to do so. Also, remember to keep in mind, herbal supplements are not necessarily approved by the FDA but instead, are only regulated.

Brewer's yeast in huge amounts can cause nausea and diarrhea. Chaparral can result in toxic hepatitis when over-dosage occurs. Comfrey in large amounts has been found to cause liver damage. Excessive use of germanium can result in kidney failure and has even resulted in death so be vigilant about any product that contains this substance. Ginseng can help memory and mental clarity in the right amounts when too much has been shown to cause blood pressure fluctuations, anxiety and insomnia. Ma Huang when taken in large amounts can cause blood pressure to increase, muscle injury to occur and nerve damage. Yohimbe has the potential to cause kidney failure, seizures and death when taken in huge amounts.

It is easy to see why you must take the right amounts of nutritional supplements. The benefits are great when used properly but the dangers, as with almost any medication or natural supplement, can be very bad. Listen to your health care professionals about how much to take and be sure to let them know what natural supplements you may be ingesting so they can ensure your health remains the very best. By avoiding dangerous over-dosage of substances that are healthy when taken in smaller quantities, always read the label and if you doctor has recommended taking more or less than the label recommendations, note that fact on the bottle or package so that you don't make a dangerous error.
