Nutritional and Herbal Supplements

By Eileen Bailey

medical conditions

The belief that large doses of vitamins (mega-vitamins) can help to decrease symptoms of ADHD is controversial. To date, there is no scientific data to back up this claim and many medical professionals have discussed the risks of taking these in large doses.

Even though there is limited or no scientific data to support many of the claims made regarding nutritional or herbal supplements, they are easily accessible. Most pharmacies today carry a large range of nutritional supplements and the Internet has many websites designed to sell consumers these products.

The FDA does not regulate these products. They do not monitor the claims of improving or curing symptoms, although in some cases, warning letters have been sent to manufacturers who make false or misleading claims to the public.

Some manufacturers of nutritional or herbal supplements rely solely on the testimonials of customers to market and promote their products. Many are lacking in scientific studies to back up claims of effectiveness.

In addition, some supplements can severely interfere with other medication you may be taking. It is very important to discuss all medications, including supplements, with your physician. Pharmacists may also be able to help you with information about interactions with current medications.
