Doppelherz is German for "Double Heart".
It is also the brand name
for a line of food supplement
s that are supposed to be good for your cardiovascular system
with ingredients like lecithin
and diverse vitamin
s. They are not classified as "real" drug
s, meaning they can be sold at any store, not only in a pharmacy
with a prescription
from a doctor.
The original "Doppelherz Energie Tonikum" was invented in 1919 (claims the website) - the manufacturer is the Queisser Pharma GmbH based in Flensburg
. The Doppelherz logo
is quite well known (at least in Germany
, that is) - take a look at www.doppelherz.de.
