Nowadays there are lots and lots of herbs and other food supplements that claim to boost energy. Some of their marketers who are desperate to sell the products or get you into their network marketing group would even tell you that these supplements would cure any type of disease - arthritis, diabetes, cancer etc
Also soft drinks and so-called energy drinks include these
products. Yet there is little or no scientific evidence to support the
claims for most of these substances. The fact is, the only thing that’ll
reliably boost your energy is caffeine or other stimulant—and their
effects wear off within hours.
Here’s a look at some of the substances that are commonly touted as energy boosters.
Chromium picolinate. This trace mineral is widely marketed to
build muscle, burn fat, and increase energy and athletic performance,
but research has not supported these claims.
Coenzyme Q10. This enzyme is found in mitochondria, the energy
factories of our cells. Coenzyme Q10 supplements have been shown to
improve exercise capacity in people with heart disease, and may do the
same in people with rare diseases that affect the mitochondria. In other
cases, the effects are not clear. One small European study suggested
that people with chronic fatigue syndrome might benefit from
supplementation with coenzyme Q10, but more research is needed.
Creatine. The body makes own creatine; it is largely found in
muscle. But it is widely sold as a supplement. There is some evidence
that taking creatine can build muscle mass and improve athletic
performance requiring short bursts of muscle activity (like sprinting).
But there is little evidence it can do the same in older adults, or that
it can reduce a feeling of fatigue in anyone.
DHEA. Sometimes marketed as a “fountain of youth,”
dehydroepiandrosterone (DHEA) is touted to boost energy as well as
prevent cancer, heart disease, and infectious disease, among other
things. The truth is that this naturally occurring hormone has no proven
benefits and some potentially serious health risks. Some research shows
that DHEA can damage the liver. It can also lower levels of beneficial
HDL cholesterol. And because this hormone is related to estrogen and
testosterone, there is concern that it may increase the risk for breast
and prostate cancers. By increasing levels of testosterone, it can also
encourage acne and facial hair growth in women. Until further research
clarifies the side effects, it’s wise to avoid taking DHEA.
Ephedra. Although ephedra was banned by the FDA in 2004
because of major safety concerns, including increased risk of heart
attack and stroke, it remains available for sale on the Internet. Any
effectiveness that ephedra may have in terms of boosting energy probably
results from two substances it contains—ephedrine and
pseudoephedrine—which may increase alertness. There is no safe amount of
ephedra you can consume. If you want to boost your energy by
stimulating your central nervous system, a cup of coffee or another
caffeinated beverage will work just as well.
Ginkgo biloba. Derived from the maidenhair tree, ginkgo biloba
has been used for centuries in Chinese medicine and is now a common
dietary supplement in Western countries. Its effects on cognition
(thinking), mood, alertness, and memory have been the subject of many
studies, but many of those studies have not been of high quality. A Cochrane Collaboration review
found the evidence was too weak to conclude that ginkgo biloba improved
cognition in people with Alzheimer’s disease. Regarding memory in
people without dementia, the evidence is contradictory. Some
studies suggest that ginkgo biloba may improve some aspects of mood,
including alertness and calmness, in healthy subjects. By making you
more alert and calm, it may increase your sense of energy.
Ginseng. This relatively safe and popular herb is said to
reduce fatigue and enhance stamina and endurance. It is sometimes called
an “adaptogen,” meaning it helps the body cope with mental and physical
stress and can boost energy without causing a crash the way sugar does.
Data from human studies are sparse and conflicting. Some studies report
that ginseng improves mood, energy, and physical and intellectual
performance. Other research concludes it doesn’t improve oxygen use or
aerobic performance, or influence how quickly you bounce back after
exercising.
Guarana. This herb induces a feeling of energy because it’s a
natural source of caffeine. But consuming a lot of guarana, especially
if you also drink coffee and other caffeinated beverages, could
ultimately lower your energy by interfering with sleep.
Vitamin B12. Some doctors give injections of vitamin B12 as
“energy boosters.” But unless they are given to correct anemia that
results from a true deficiency of the vitamin, there is little evidence
that vitamin B12 treatments boost energy.
Instead of relying on a supplement for energy, I recommend switching
to a healthful diet—more vegetables, fruits, whole grains, nuts, lean
protein, and unsaturated fats—and exercising more. That’s truly a better
way to beat an energy shortage, and it’s one your whole body will appreciate.
