When it comes to sports performance supplements,
there are few ingredients better known than creatine.
Creatine helps to supply energy to cells, particularly
in muscle, by assisting in the formation of the body’s energy
currency, adenosine triphosphate (ATP).
But athletes are often unaware that ATP generation requires
creatine to first gain entry to muscle. Creatine floating around in
the blood is useless if not absorbed by muscle tissue. Yet taken
by itself (usually as creatine monohydrate), a significant portion
ends-up being simply excreted, i.e., being useless. The reason:
low insulin levels.
Insulin normally signals muscles to absorb creatine. But
without food to signal insulin secretion, creatine uptake is
minimal. Beyond taste, creatine formulas are often packed with
sugars for this very reason. But as many performance athletes
attempt to reign in their refined sugar consumption and avoid
taxing their bodies with insulin spikes, they are left in a bind
trying to eliminate caloric load while using creatine effectively.
Russian Tarragon: Sugar-less Creatine to Muscles
Enter Russian Tarragon (Artemisia dracunculus). Diabetes
research programs have recently demonstrated Russian
Tarragon to have insulin sensitizing action.1 This means that
although it doesn’t increase insulin secretion, it allows existing
insulin levels to have a stronger influence on the body. This
is important in Metabolic Syndrome (a.k.a. insulin resistance
syndrome) in which there’s plenty of insulin in the body, but the
body’s receptors have become “hard-of-hearing.”
For healthy individuals, this presents an alternative way to
induce creatine clearance from blood without the caloric load or insulin spike. Recent research in healthy males demonstrated
that taking one gram of a Russian Tarragon extract along with
creatine monohydrate under test conditions led to a significantly
greater clearance from blood (and presumably into muscle).
The effect was comparable to that achieved by using 75 g of
glucose or 50 grams of protein plus 47 grams of carbohydrates.2
Five hundred milligrams taken 30 minutes prior to creatine
supplementation did not affect whole body creatine levels and
retention, however, meaning that a good response requires at
least one gram per day.3
Glycostat® Bitter Melon: More Insulin Sensitivity & Creatine Uptake
Bitter melon (Momordica charantia) is another botanical that
has a history of use in food and medicine. Like Russian Tarragon,
bitter melon has shown tantalizing results in stimulating insulin
sensitivity. This implies it may be useful in helping to induce
creatine uptake from blood into muscles, an effect found
with glucose also to be expected with amino acids.4 Work in
diabetic animals suggests that a one-gram dose of a particular
Wild Bitter Melon extract in humans can lead to a sustained 15
percent increase in the muscle uptake of nutrients like creatine
for hours after ingestion.
Other research has shown that bitter melon is useful in the
mobilization of fats for energy via beta-oxidation.5 Everyone
knows fat is an excellent source of energy, but sometimes the
body forgets how to utilize it. Bitter melon helps provide a
The biggest trick with bitter melon is finding a dried
extract that retains the activity of the fresh fruit. Many do
not. Glycostat® Wild Bitter Melon appears to be head-and-shoulders
above the rest.6
Help enlighten those who take creatine. There are other
ingredients out there that can make it more effective—without
the added sugar.
