NEW study: Zinc lozenges failed to be effective during cold

Zinc lozenges are traditionally used to treat common colds.

Finnish researchers showed in a recently published study1 (number of participants = 253) that zinc lozenges cold not support the healing process of a common cold.

Moreover, the Finnish researchers found that recovery of the common cold was prolonged when taken Zinc lozenges.

In contrast to that, 3 clinical studies 2,3,4 proved the effectiveness of Yestimun® by

  • lesser severe cold symptoms,

  • even fewer common colds during intense infection seasons and

  • shorter duration of an episode of a common cold.

Now it should be clear why at least ALL formulas with zinc should also contain Yestimun® 😉
