One of our best selling products is SugarReg. Nature's Sunshine
has reformulated this product to include the health properties
of cinnamon. Here's some research information on this easy-to-find
spice. Now you've got a great excuse for cinnamon toast, apple-
cinnamon pie, and other cinnamon goodies that you like.
The Health Benefits Of Cinnamon
by Shannon Larsen
Cinnamon has become increasingly popular for its positive
effects on blood sugar levels. Cinnamon contains a phytonutrient
called methylhydroxychalcone polymer (MHCP), which has been
shown to aid in maintaining healthy blood sugar levels already
within the normal range.1 Different species of cinnamon exist,
and some studies have shown that the Cinnamomum cassia species
is most effective in promoting healthy blood sugar levels.2
In a recent clinical study, 65 people with diabetes were given
either a placebo or 3 grams of ground cinnamon bark for four
months. Results showed that fasting glucose levels decreased
by 10% in the individuals that were given cinnamon bark and
did not change in those given the placebo.3
Another study, published in the Journal of the American College
of Nutrition, focused on the mechanism of action of the MHCP
component of cinnamon. Results of this in-depth study demonstrated
that MHCP increased glucose uptake, stimulated insulin receptors,
increased the synthesis of glycogen (the storage form of glucose)
by up-regulating the activity of glycogen synthase (the enzyme
responsible for the formation of glycogen), decreased activity
of GSK-3B (an enzyme that inhibits glycogen synthase), and
that there was a synergistic effect when MHCP and insulin were
combined in both the glucose uptake and glycogen synthesis
assays.4
Insulin and MHCP showed similar effects in all of the tests
except the glucose uptake assay, in which MHCP was even more
effective than insulin. A lower dose of MHCP was needed compared
to insulin to achieve the same amount of glucose uptake by
cells.4
It was also observed that MHCP more effectively inhibited
GSK-3B enzyme compared to insulin. To explain the synergism
seen when MHCP and insulin were combined, the researchers suggested
that MHCP and insulin may stimulate insulin receptors through
different mechanisms, and when combined, there is a greater
response. MHCP may have multiple effects within the cell. It
may cause an insulin-like response via the insulin receptor
and affect enzymes involved in blood sugar regulation.4 The
results of this study show that MHCP exerts its beneficial
effects on blood glucose levels by mimicking the effects of
insulin.
The oil of cinnamon has been linked to side effects, including
vomiting, dizziness and diarrhea.5 However cinnamon oil is
much more concentrated than the powdered bark or cinnamon bark
extract, and no health hazards or side effects are known to
be associated with the proper administration of designated
therapeutic dosages of cinnamon bark.6
Cinnamon bark has GRAS (generally recognized as safe) status
in the U.S. and is likely safe when used orally in medicinal
amounts.5 As a general precaution, it is recommended to avoid
taking large amounts of cinnamon when pregnant or breastfeeding
due to insufficient information available on the use of cinnamon
bark during pregnancy and lactation in amounts greater than
those found commonly in foods.5
Healthy blood sugar levels are essential to maintaining optimum
health. In addition to seven ingredients that have a history
of successful use in promoting healthy blood sugar levels already
within a normal range, the new and improved SugarReg includes
safe, yet effective amounts of cinnamon bark (Cinnamomum cassia)
to provide enhanced blood sugar support.
