Japanese Health Drinks

Mikuru-chan serving up some Yunker health drink for me.
Commercials for these health/energy boosting drinks can be seen on TV all the time and in ads which usually feature tired salary men.
Dont usually drink them as they taste yukky and cost a few hundred yen for a single gulp ^^;
My wife brought back a box and to my surprise taste really good - so good that I need to sneak to the refrigerator to have more than one a day ^^;
Are health/energy boosting drinks popular in your region too?
A retro ad for Yunker below.
