Vitamins, Minerals, and Amino Acids
These are all the little things that your body needs for proper functioning of various biochemical
processes. Deficiencies in any of these will have consequences, some more severe than others.
But fear not, because for the most part, you get everything you need from a balanced diet. Eating
fruits and vegetables is your best natural source, and processed foods are your enemy. When following
a vigorous exercise regimen, you're requirements will be higher than if you were a couch potato.
The simplest way to ensure you won't suffer from a deficiency is to take a good multi-vitamin/mineral
every day, and consume either meat, or a variety of plant protein sources (for essential amino acids).
If you feel it is necessary because your diet isn't the greatest and/or you work out
tons, you might also consider an anti-oxidant and/or stress formula.
Most of the vitamins are water soluble, and any excess is easily excreted by the body, but you have to
be careful of the fat-soluble ones ( vitamins A, D, E, and K) which can build up and reach toxic levels.
Taking too much of any one mineral can also be bad as it causes an imbalance, and may hog receptor
sites causing deficiency symptoms to show up for another mineral.
Aside from a regular multi-vitamin/mineral tablet every day, the only thing I've seen recommended
for bodybuilders (consistently) are antioxidants. These include vitamins A(beta carotene), C, E,
One other recommendation I can make from personal experience is magnesium supplementation if you can't
seem to sleep a night through (about 500 mg should do it, though I've heard as much as 1000).
Here is a list of vitamins, minerals and amino acids, broken down one by one, describing function and symptoms of
deficiencies. I got most of the information from
'AUSTIN NUTRITIONAL RESEARCH', an online vitamin/supplement company with loads of information! If
you're really interested in all the nitty gritty details, check it out!
As time goes on, I will add to this list notes of importance to those of us training for a better body.
To differentiate from the rest, my notes will be in yellow for easy identification.
A word about RDA. The RDA was a guideline established over 50 years ago to prevent
scurvy and the like, but are not necessarily enough for optimum health. More recently, a new
measure called the RDI, or Reference Daily Intake has been established by the FDA which
does support optimum health. But it's still a minimum guideline.
Next to each heading for vitamins and minerals, I will post the new RDI values, as well as a
dosage suited more to active athletes (this value should be taken as an upper limit, and not be exceeded)
which I will denote by BBRDI. Both these values are taken from the 'Oxygen', a new magazine for
women's fitness by Robert Kennedy.
And lastly, I will give a list of food sources which are abundant in the various micro-nutrients. These
are also taken from 'Oxygen', though I will be adding other sources on my own. Maybe when I have time, I'll
go over the recommended sources just to verify them (using the
USDA online database). One example I
checked was manganese in bananas, and according to USDA, bananas don't have a lot. So who is right? USDA
looks a bit more thorough. Feel free to check any foods there if you have doubts, and let me know
if you find discrepancies!
VITAMINS:All natural vitamins are organic food substances found only in living things, that is, plants and
animals. With few exceptions the body cannot manufacture or synthesize vitamins. They must be supplied in
the diet or in dietary supplements. Vitamins are essential to the normal functioning of our bodies. They are
necessary for our growth, vitality, and general well-being.
HOW THEY WORK: A lot of people think vitamins can replace food. They cannot. In fact, vitamins cannot
be assimilated without ingesting food. That is why we suggest taking them with a meal. Vitamins help regulate
metabolism, help convert fat and carbohydrates into energy, and assist in forming bone and tissue.

As important s vitamins are, they can do nothing for you without minerals. Vitamins cannot be assimilated
without the aid of minerals. And though the body can manufacture a few vitamins, it cannot manufacture a
single mineral. All tissues and internal fluids of our body contain varying quantities of minerals. Minerals are
constituents of the bones, teeth, soft tissue, muscle, blood, and nerve cells. They are vital to overall mental
and physical well-being.
Minerals act as catalysts for many biological reactions within the body, including muscle response, the
transmission of messages through the nervous system, the production of hormones, digestion, and the
utilization of nutrients in foods.

Minerals that occur in tiny amounts or traces. They play a major role in health, since even minute portions of
them can powerfully affect health. They are essential in the assimilation and utilization of vitamins and other
nutrients. They aid in digestion and provide the catalyst for many hormones, enzymes and essential body
functions and reactions. they also aid in replacing electrolytes lost through heavy perspiration or extended
diarrhea and protects against toxic reaction and heavy metal poisoning.
AMINO ACIDS are the "building Blocks" of the body. Besides building cells and repairing tissue, they form
antibodies to combat invading bacteria & viruses; they are part of the enzyme & hormonal system; they build
nucleoproteins (RNA & DNA); they carry oxygen throughout the body and participate in muscle activity.
When protein is broken down by digestion the result is 22 known amino acids. Eight are essential (cannot be
manufactured by the body) the rest are non-essential ( can be manufactured by the body with proper
