2015 Zinc Lozenges for Colds (03/17/2015)
Zinc Lozenges for Colds
A recent review of placebo-controlled studies of zinc lozenges given at the start of a cold shows that they not only shorten the duration of symptoms in the throat, but in the nose and muscles as well. It is critical, however, that the right type of zinc, dose, and dosing schedule be used.

2011 Women-Vitamin Study - Key Points (10/12/2011)
Women-Vitamin Study - Key Points
You may have heard this week about a new study which found a higher risk of death among women who used certain supplements. It’s a complicated study, but we've summarized some key findings. Bear in mind that only white women ages 55 to 69 were enrolled in the study and they were followed for 22 years.

Those taking calcium supplements had a 3.8% reduced risk of death. The calcium benefit ended, however, when taking more than 900 mg per day from supplements. It's worth noting that experts suggest many older women who take calcium supplements may not need to -- see the Calcium Supplement Review for more.

The mineral most strongly associated with an increased risk of death was iron, which showed a risk increase of 3.9% -- and the risk increased as the dose increased, particularly over 50 mg per day. However, the study grouped dosages of under 50 mg together, making it hard to determine the risk of low dosages of iron, such as those in many multivitamins. However, there is very little reason why a postmenopausal woman should be taking iron -- see the Iron Supplement Review for more.

Although not as statistically meaningful, other supplements were associated with the following increases in the risk of death during the study: multivitamins (2.4%), vitamin B6 (4.1%), folic acid (5.9%), magnesium (3.6%), zinc (3.0%), and copper (18.0%). An abstract of the study is online.

The bottom line: Don't take a supplement you don't need. If you want to know how much of each vitamin and mineral you need from your total diet and how much is too much, see our chart at
 Zinc for Colds -- Be Careful (02/27/2011)
Zinc for Colds -- Be Careful
The use of zinc for colds has been in the news lately due to a study indicating benefit. Some of the coverage, however, might suggest the wrong conclusion. Be aware that taking zinc pills won’t help with a cold; only forms that allow zinc to act directly in the throat or nose can help – and only when taken appropriately. See the Zinc Product Review for details on formulations and dosing that can help with colds. More >>
