Broadly speaking, there are two ways
you can increase your energy levels through nutrient supplementation.
The slower way is by eating quality
food and by taking supplements that will enhance your immune
system, and strengthen your body systems. (Appropriate exercise
and relaxation are an essential part of this) This way may take
longer, but the extra energy you get will be truly coming from your
body. You won't "crash" when you stop taking them, although
you may feel normal fatigue.
The faster way is by taking stimulants.
These trick your body into thinking you've got more energy than
you really have, and make you able to produce more energy than unassisted
(sugar is the most commonly used stimulant). But once they wear
off, you are likely to feel worse, and need to take more. And when
you stop taking more, chances are you'll get sick. Or you'll get
sick first, and have to stop taking them while you recover.
Some people have strong constitutions
and can get away with taking stimulants for long periods of time.
Some people don't and can't. I'm not saying "don't take stimulants"
(you probably wouldn't listen if I did!) but be informed. Know what
effect they are having on your body and be cautious.
Supplements
to help build energy & stamina
For supplements that will build the
immune system, see the herbs
and supplements page. Discussed here are a few particular substances,
that some people have found give them more energy. But taking them
only before training and competition probably won't make a big difference.
They may have small amounts of stimulants that give you a bit of
a "buzz", but in general, think of them as foods that
will assist you in building a better body over time.
Ginseng - The two most common varieties
of Ginseng are Korean (Panax) and Siberian. They both have a long
history of medicinal use (see the herbs
& supplements page for details). They are available singly,
and some sports formulas include both of them.
As far as sports performance goes,
historical use suggests that Siberian Ginseng is the preferred variety,
although I don't know of any studies done to back this up. Michael
Colgan quotes studies done on Panax Ginseng, which suggest that
continued use of it can improve endurance, increase brain &
hormone activity, and lung power, and reduce lactic acid, fatigue
and glycogen use.
Bee Pollen contains many essential
nutrients. Pollen is the male germ of flowering plants. As bees
forage, the pollen mixes with nectar and accumulates in yellow granules
on the bee's legs. It is an excellent nutritional supplement for
enhancing immunity and, with its strong nutritional profile, for
providing energy. It contains up to 35% complete protein, as well
as 22 amino acids, an especially rich storehouse of B vitamins,
27 mineral salts, trace elements and several enzymes. Greeks called
it the "nectar of the gods." Many performance and endurance
athletes use it before workouts and competition. Precaution
: Open capsule & take minute amount to check for
allergic reaction. Don't take in cases of high blood pressure.
Spirulina - A micro-algae, which
is highly nutritious and an excellent source of protein, chlorophyll,
vitamins and minerals, essential fatty acids and amino acids. It
has 26 times the calcium of milk, contains phosphorus, B12, RNA
and DNA, and is easily digested. It is safe food with no side effects.
Spirulina is used for fatigue and as an aid during fasting. Also
available are combinations of algae which include spirulina, chlorella
and other algae.
Although many people consider it a
superfood, the downside of it is that you would need to take a large
number of pills to get any significant amount of protein from it.
Using powder in a shake is probably a better way to take large amounts.
And remember that it's very concentrated, and large quantities without
enough water can make you dehydrated.
Stimulants
Coffee/ Caffeine - There are two
ways you can use caffeine. You can use it on a daily basis to get
you going in the morning and keep you going through the day. But if
you do that, it doesn't work as a performance aid, as your body is
already used to it. Once a week is the maximum number of times
it can be used to avoid the body becoming habituated to the effect.
If you are fit and don't take coffee, guarana,
energy drinks, chocolate or any other form of caffeine regularly,
you can get a beneficial effect by taking about 7.5-10mg per kg
of bodyweight of caffeine 3-4 hours before exercising. It can help
you to go harder for longer, to use more fatty acids for fuel, and
to reduce lactic acid build-up. Drink good quality coffee, preferably
organic, (Michael Colgan recommends Coffea arabica beans)
and enjoy!
Energy Drinks (such as Red
Bull, V, etc) are essentially an alternative form of caffeine, if
you want a change from coffee. But they contain many other unhealthy
ingredients such as colourings, flavourings, preservatives, and
large amounts of sugar or artificial sweeteners, all of which are
toxic. Remember that caffeine is highly addictive. If you consume
caffeine in any form more than once a week, you are probably be
addicted to it. To test this, go without for six days without, and
see if you develop headaches or other withdrawal symptoms.
Guarana - Thought
to be a Central Nervous System stimulant. The active ingredient is
caffeine, but it is about 2.5 times stronger than coffee. It quickens
your perceptions and wakefulness, slows the pulse, impairs the appetite,
and can be used to allow for long drives, extended work hours, endurance
based athletics, and delaying sleep. Some people find that guarana
improves performance without as many side-effects as coffee.
The benefits claimed for Guarana are:
that is a general tonic for the nervous system and muscles, it increases
sexual energy and regulates blood circulation without interfering
in blood pressure, it regulates the gastric and intestinal functions
fighting diarrhea and flatulence, it is an antiseptic and astringent
and is also a useful natural medicine to fight against intestinal
constipation. It is an emulsifier of fats, limits cholesterol &
arterial sclerosis and is a stimulant for mental activities.
CAUTION : Long term use of Guarana
alters the blood sugar, which can cause nervousness, insomnia and
possible psychic habituation. Vitamin B supplements can help counteract
this.
Ephedrine - Increases alertness
and gives a sense of euphoria. A powerful stimulant that boosts
short term athletic performance. Can be useful as a weight loss
aid, without sacrificing lean muscle. It's now classified as a drug
in New Zealand, so is no longer legally sold, but it's still quite
widely used as a weight loss, recreational, and performance stimulant.
Although it an effective booster in the very short term, it is like
"turbo-charging" the body, and may rapidly lead to a wide
range of health problems, such as adrenal exhaustion, chronic fatigue,
mental stress, and lowered immunity.
There are many other supplements and
stimulants available, but there are no easy shortcuts to instant
high energy levels, and unnaturally fast gains generally come at
the price of impaired overall health.
