Nutrition supplements can be purchased over-the-counter, which means they do not have to use prescriptions. Generally, the public feels they are safe, even if the most are not recognized and regulated by the Food and Drug Administration. How much do we really know about nutritional supplements? Is there a nutritional supplement? Here are some things to think about:
1. Dosage and topical use
Excessively suppressed substances are not good for health. The same goes for nutritional supplements. The OHSU study by Frederick W. Fraunfelder, MD, researcher and ophthalmologist, says dry eyes, temporary visual loss and retinal bleeds as some side effects of certain dietary supplements, some nutrition and herbal supplements. Most of the nutritional supplements are related to topical use and high doses. Although there was no permanent damage, there is still a possibility that the patient will continue to use the product.
There have been eight variables for ophthalmic adverse events: Echinacea purpurea, ginkgo biloba, chamomile, canthaxanthin, licorice, Datura, vitamin A and niacin. Some of these products, especially gingko biloba, with other medicines, such as aspirin and ibuprofen, have side effects.
Multivitamins should be taken moderately – over-dosing of unrecognizable vitamins in the body can cause serious problems. For example, high doses of iron and vitamin D may cause kidney damage; too much vitamin A can cause headache, diarrhea, nausea and bone and liver damage
. Medical history
Some nutritional supplements are caused by existing health conditions, history or treatment. For example, some asthma patients may be allergic to higher doses of vitamin C. patients with diabetes, hypertension / kidney stones and reflux nephropathy are at risk for food supplements, such as kidney failure when using creatine supplements
TIP: It is still best to have a doctor with intake of food supplements connection; this is especially important in patients receiving any medication or healing or in special cases such as pregnant women.
It is also useful to read medical guides, brochures, and consumer reports to get information about some nutritional supplements, whether or not they have side effects. You can also view the World Health Organization (WHO) World Health Organization (WHO) database for prohibited or rejected food supplements. Please note that some additives contain additives that may harm you. Make sure that the supplement manufacturer is GMP-compliant in the pharmaceutical industry – this guarantees that your product does not contain any harmful fillers.
