With the high holidays in sight, I am sending this email to you-and, especially for the chazanim- with a piece of advice to have at home Astaxanthin, in case you experienced voice problems in the past during the lengthy prayers.
One can safely take one tablet today for a few days if necessary.
I have some good experience with it with a few patients who were hoarse[tzarud].
It may work fast and can be taken even as a prevention.
