Because
women with higher blood levels of vitamin D were much less likely to be insulin
resistant
In an insightful associative study that
highlighted the link between PCOS and vitamin D status, researchers found that
women with higher blood levels of vitamin D were much less likely to be insulin
resistant (Wehr 2011). A separate study found that vitamin D when administered
with metformin was helpful for regulating the menstrual cycles in PCOS women
(Rashidi 2009).
A study conducted by researchers at Columbia
University found that Vitamin D combined with calcium supplementation helped
normalize menstrual cycles for seven of 13 women with PCOS. Of the seven, two
became pregnant and the others maintained normal menstrual cycles. These
results suggest that abnormalities in calcium balance may be responsible, in
part, for the arrested follicular development in women with PCOS and contribute
to its pathogenesis (Thys-Jacobs 1999).
What
is the role of Omega-3 Fatty Acids to minimize metabolic ill effects of PCO??
Omega 3 FA:How useful in controlling PCO?? How useful is omega
3 fatty acids in PCO where CRP is raised and there is vascular endothelial dysfunction?? Ans:---Evidence
suggests that the anti-inflammatory activity of omega-3 fatty acids ameliorates
non-alcoholic fatty liver disease, a common condition in women with PCOS. In an
Australian study, omega-3 fatty acid supplementation reduced liver fat content
and other cardiovascular risk factors in women with PCOS, including
triglycerides, and systolic and diastolic blood pressure. In particular, said
the researchers, omega-3 fatty acids were helpful in reducing hepatic fat in
PCOS women with hepatic steatosis, which is defined as liver fat content
greater than 5% (Cussons 2009).
How useful is Flaxseeds in PCO??
How useful in controlling
PCO??
The powerful lignans—plant compounds that
have both estrogenic and antiestrogenic properties—in flaxseed may help reduce
androgen levels in PCOS women. Flaxseed consumption have been shown to
stimulate sex hormone-binding globulin (SHBG) synthesis (Shultz 1991). Changes
in SHBG concentration result in relatively large changes in the amount of free
and bound hormones.
In a 2007 study, daily flaxseed
supplementation reduced androgen levels and hirsutism in PCOS patients, leading
researchers to conclude, “The clinically-significant decrease in androgen
levels with a concomitant reduction in hirsutism reported in this case study
demonstrates a need for further research of flaxseed supplementation on
hormonal levels and clinical symptoms of PCOS.” (Nowak 2007).
Cinnamon How useful in controlling PCO??
Scientists at the US Department of
Agriculture (USDA) have been studying the effect of cinnamon on blood glucose
for over a decade, leading to several interesting discoveries, including that
of unique compounds in cinnamon bark that in laboratory studies produce a
20-fold increase sugar metabolism (Broadhurst 2000, Cao 2010). According to one
government expert, “These polyphenolic
polymers found in cinnamon may function as antioxidants, potentiate insulin
action, and may be beneficial in the control of glucose intolerance and
diabetes.” (Anderson 2004).
In a 2003 study, 60 diabetics taking 1, 3, or
6 grams/day of ground cinnamon for 40 days lowered their fasting serum glucose
by 18% to 29%; triglycerides by 23% to 30%; LDL cholesterol by 7% to 27%; and
total cholesterol by 12% to 26% (Khan 2003).
A 2007 study by researchers at Columbia
University found that cinnamon reduced insulin resistance in fifteen women with
PCOS. In the study, the women were divided into two groups: one group took
cinnamon extract while the other group took a placebo. After 8 weeks, the
cinnamon group showed significant reductions in insulin resistance while the
placebo group did not. The authors did point out that, "A larger trial is needed to confirm
the findings of this pilot study and to evaluate the effect of cinnamon extract
on menstrual cyclicity."(Wang 2007).
What is the role of Licorice
Root in
PCO?? How
useful in controlling PCO??
A 2004 study by Italian researchers
investigated the effect of licorice on androgen metabolism in nine healthy
22-26 year old women in the luteal phase of their menstrual cycle and found
that licorice reduces serum testosterone. The authors suggested that licorice
could be considered an “adjuvant therapy of hirsutism and polycystic ovary
syndrome." This study was the first to follow up on earlier trials, which
found that an herbal formula containing licorice reduced testosterone secretion
in women with polycystic ovary syndrome (Armamani 2004, Takahashi 1988,
Takeuchi 1991).
