Health Alert: Supplements may do more harm than good

Posted: Updated:

(CBS) - A new study in the journal of the American Medical Association finds men who take Vitamin C supplements are twice as likely to develop kidney stones. A second study finds calcium supplements can increase the risk of heart disease in men. Researchers in both studies say foods rich in Vitamin C and calcium are a better choice than supplements.


(CBS) - Doctors say the sun may help prevent rheumatoid arthritis in women. Researchers followed more than 120,000 nurses in the U.S. for more than 30 years. They found those who spent a lot of time soaking in ultraviolet B rays had a 21 percent lower risk of developing rheumatoid arthritis. The sun helps the body produce Vitamin D which helps keep bones healthy.


(CBS) - Television may hurt a man's chances of having a child. A new study from the University of Rochester shows young men who watched 20 hours of TV a week had a much lower sperm count. Researchers say men can improve their count significantly if they exercise at least 15 hours a week.


(CNN) - They may seem harmless, but those energy drinks can be dangerous, especially for teens. Doctors find they contain high amounts of caffeine, as well as other ingredients that can produce an even stronger jolt. Drinking a lot of them can lead to harmful effects including heart issues, anxiety, digestive problems, insomnia and dehydration.

Mix them with alcohol, which doctors say a lot of teens do, and the problems intensify. The American Beverage Association says there's plenty of caffeine in lots of drinks that are available to a younger age group, including coffee from coffeehouses. The new study is found in the Journal of Pediatrics.
