We started taking Zinc to help with the cold season as Zinc is known to have possible benefits in this department. You'll find that the 21st Century brand offers an excellent value as they don't spend as much as the big players advertising. The bottle has 110 tablets, enough for the entire family. The pills can be broken too. We take this product along with Vitamin C especially during the cold and nasty wintery and Spring months just around the corner. Please click on my profile!
They do the trick

My zinc levels were low, so I began taking this supplement to help with the situation. I didn't know much about the brand, but they had good reviews and were inexpensive. Less than halfway through the bottle and my levels were already improved, so I will stick with this one. If my review helped you, please check the yes box below.

Improves my immune system

After buying a bottle to try out , I bought more again . Since my daily diet lacks zinc ,these zinc supplements really have been helping improving my immune system . Can't remember the last time I felt really sick after consuming these once per two days (remember to take vit C fruits too) . While its still better to absorb zinc naturally from nuts , having some zinc tablets isn't all that bad too.
Affordable and Efficient

DUE TO A SEVERE GUT CONDITION I HAVE A PROBLEM ABSORBING NUTRIENTS. SINCE I HAVE STARTING THE USE OF THIS, MY ZINC LEVELS HAVE RETURNED TO WITHIN THE NORMAL RANGE.

Zink deficiency is quite common. RDA is around 10 mg a day, but new clinical trials suggest it is better to consume 15-30 mg a day. A normal diet yields at most 10-15 mg, so supplementing 5-10g a day is adviced. I take one of theese zink tablets once a week, which evens out to about 7 mg a day. I'm perfectly happy with it, and will purchase again when it runs low. This will take a couple of years though, since the bottle contains 110 tablets (10% extra in the bottle at no extra cost).
