Stevia: New Flavors Now Available
Extracts of leaves from Stevia rebaudiana have been used for many years in traditional treatment of diabetes in South America. Various compounds in stevia has been
concentrated, and used as natural sweeteners. These compounds possess up to 250 times the sweetness intensity of sucrose, and they are noncaloric and noncariogenic.
Stevioside, a natural plant glycoside isolated from the plant Stevia rebaudiana, has been commercialized as a noncaloric sweetener in Japan for more than 20 years.
Some studies have shown that stevia may be beneficial to those with hypertension, and those with type-2 diabetes. Dosage: Add 2-8 drops, as needed. Each ml is equiv-
alent to 300 mg of Stevia. Willner Chemists has offered stevia as a liquid herbal concentrate, providing Stevia Leaf Extract, standardized to 90% Steviosides, in 1, 2 and 4

How to Choose the Right
Supplement
. . . an excerpt from the digital edition
of The Best Supplements For Your
Health, Chapter Two
The widely acclaimed book, The Best
Supplements For Your Health, by Don
Goldberg and Arnie Gitomer, is now being
revised and updated. This will be an ongoing
process, and a free, digital version will be
posted in the Reference Library section of the
Willner Chemists web site,
www.willner.com
At this time, Chapters One through Five are
available online. Below, part of Chapter Two:
How To Choose The Right Supplement, is
reprinted. Comments are welcome.

Choosing a supplement is not
always easy. Which supplements do
you need? How do you choose a
quality supplement? How should
the supplement be taken? Is a cap-
sule better than a tablet? Is there any
potential interaction between the
supplement and your medications?
There are many choices to be made,
some of which are highly individual
and related to personal preference.
Others require some knowledge of
chemistry and physiology, and an
ability to differentiate marketing
hyperbole from fact. Your personal
health problems and needs have to
basis and should be verified by full-
disclosure labeling. In addition, you
should take into account the compo-
sition of the capsule itself, which
can contain additives as well. Is this
really cause for concern? We will
answer that question in the next sec-
tion.
The main factor that should influ-
ence this decision is actually ease of
swallowing. For many people, it is
easier to swallow a capsule. Once it
becomes wet, many feel that it
slides down more easily. Others pre-
fer tablets. This is purely a personal
decision.
One advantage of tablets is that
they are usually less expensive than
capsules. It costs less to manufac-
ture a tablet than it does a capsule.
For those on a tight budget, it usual-
ly makes sense to buy tablets. Also,
you can squeeze a greater amount of
material into a tablet than a capsule.
When we discuss multivitamin
products later in the book, you will
see that the same formula that
requires four tablets will require six
capsules.
In some cases, an encapsulated
product may be more stable than a
tablet. If the ingredients are subject
to oxidation or are sensitive to mois-
ture, the capsule may offer some
additional protection, although
tablets can be coated, which also
can serve as a protective barrier.
This is rarely significant when mak-
ing your choice. Proper storage is
more important. One example, how-
ever, where this protective function
does come into play is with essential
oils such as flaxseed oil. When buy-
ing oil, you will notice that it must
be kept refrigerated. This is because
oil is easily oxidized. But when
flaxseed oil is put into soft gelatin
capsules, refrigeration is not neces-
sary because the capsule protects
the oil from contact with air.
Both tablets and capsules, if manu-
factured by a responsible company,
will be tested for disintegration and
dissolution. These are standardized
tests, provided for in the United
States Pharmacopeia (USP), that
show whether or not the product
will dissolve and release its active
ingredients after being swallowed.
The key here is a responsible com-
pany. Theoretically, it is probably
easier to make a bad tablet than it is
to make a bad capsule. If the tablet-
ing process is not done properly and
is not carefully monitored, and if the
tablet is not formulated properly, a
tablet that does not dissolve could
be produced. It could be too hard,
for example. If the company does
not adequately test the tablets, they
might not dissolve properly. If you
buy products only from reputable
companies, this should not be a con-
cern, but if you insist on buying
cheap products from questionable
sources, you might want to stick

be considered. The information that
follows will help you with these
decisions.
Choosing the right supplements
can be broken down into four
steps:
1. Choosing the right type of
supplement for you.
2. Choosing supplements tai-
lored to your unique health prob-
lems and needs.
3. Choosing the specific brand or
product to purchase.
4. Incorporating these choices
into a comprehensive program
tailored to your needs.
Step One: Choosing the
Right Type of
Supplement
Tablets and Capsules
Many people think that capsules
are superior to tablets because they
dissolve better or have fewer addi-
tives. This is not correct. A properly
manufactured tablet will work just
as well as a capsule. The so-called
superiority of capsules in this regard
is a myth propagated by some com-
panies selling encapsulated supple-
ments.
Theoretically, there may be times
when a capsule could contain fewer
additives, but this is true only in cer-
tain instances. Such a claim must be
evaluated on a product-by-product
