In looking for a study, I found this one. It discusses the protective effects of both melantonin and propolis against the damage done by a smart phone on the kidneys of rats.
Ever carry your smart phone close to your flanks, as in your back pocket? Or close to your heart, as in your shirt pocket? It's a good habit to break!
EVER CARRY YOUR PHONE CLOSE TO YOUR BABY????
Time to learn more about liposomal melantonin and propolis.

Comparative analysis of the protective effects of melatonin and caffeic acid phenethyl ester (CAPE) on mobile phone-induced renal impairment in rat.
Abstract
Melatonin
and caffeic acid phenethyl ester (CAPE), a component of honeybee
propolis, were recently found to be potent free radical scavengers and
antioxidants. There are a number of reports on the effects induced by
electromagnetic radiation (EMR) in various cellular systems. Mechanisms
of adverse effects of EMR indicate that reactive oxygen species may play
a role in the biological effects of this radiation. The present study
was carried out to compare the protective effects of melatonin and CAPE
against 900 MHz EMR emitted mobile phone-induced renal tubular injury.
Melatonin was administered whereas CAPE was given for 10 days before the
exposure. Urinary N-acetyl-beta-D-glucosaminidase (NAG, a marker of
renal tubular injury) and malondialdehyde (MDA, an index of lipid
peroxidation), were used as markers of oxidative stress-induced renal
impairment in rats exposed to EMR. Superoxide dismutase (SOD), catalase
(CAT), and glutathione peroxidase (GSH-Px) activities were studied to
evaluate the changes of antioxidant status in renal tissue. Urinary NAG
and renal MDA were increased in EMR exposed rats while both melatonin
and CAPE caused a significant reduction in the levels of these
parameters. Likewise, renal SOD and GSH-Px activities were decreased in
EMR exposed animals while melatonin caused a significant increase in the
activities of these antioxidant enzymes but CAPE did not. Melatonin
caused a significant decrease in urinary NAG activity and MDA levels
which were increased because of EMR exposure. CAPE also reduced elevated
MDA levels in EMR exposed renal tissue, but the effect of melatonin was
more potent than that of CAPE. Furthermore, treatment of EMR exposed
rats with melatonin increased activities of SOD and GSH-Px to higher
levels than those of control rats. In conclusion, melatonin and CAPE
prevent renal tubular injury by reducing oxidative stress and protect
the kidney from oxidative damage induced by 900 MHz mobile phone.
Nevertheless, melatonin seems to be a more potent antioxidant compared
with CAPE in kidney.
