Vitamin D has long been associated with bone health in women.
A new study in the Journal of the National Cancer Institute found that higher circulating Vitamin D levels appear to be associated with a lower risk of colorectal cancer.
Here are some of the findings in that study:
-25(OH) D or 25-hydroxyvitamin D is the measurement that is made to establish circulating Vitamin D levels
-the level of 25(OH) D that is sufficient for bone health is considered to be around 55 nmol/L
-Vitamin D levels less than 30 nmol/L appear to be associated with an increased risk of colorectal cancer
-Vitamin D levels of 75-87.5 nmol/L seems to be associated with a 19% reduced risk of colorectal cancer
-Vitamin D levels of 87.5-100 nmol/L seems to be associated with a 27% reduced risk
-Vitamin D levels above 100 did not seem to reduce the risk even more.
Of course, more studies are needed to arrive at the proper Vitamin D guidelines but you should discuss these new findings with your health care providers.
…..It seems that every day there is a study revealing the importance of having a normal level of vitamin D. A new report even points to an association between fibroids and vitamin D. Uterine fibroids are benign tumors of the uterine smooth muscle, and this affects approximately 30 to 40% of all women. It is one of the leading causes for a hysterectomy in the United States. In the laboratory it has been shown that an active metabolite of vitamin D can inhibit the growth of fibroid tissue.
…..Approximately 1000 women ages 35 to 49 years old were enrolled in a study where the vitamin D level was obtained, and the fibroid status was determined by ultrasound screenings of these premenopausal women. The group with normal vitamin D levels had a 30% lower risk of fibroids as compared to those with vitamin D insufficiency.
…..More research needs to be done to confirm these findings but it seems that sufficient vitamin D may be associated with a reduced risk of uterine fibroids. As always, speak to your health care provider before beginning any new vitamin supplement program.
…..The new year comes with all the resolutions we promise to keep. Weight loss is
always the one we want to accomplish. I wish to remind you again to continue your vitamin D supplements if you were found to be needing them. Every day I read about the importance of this vitamin and appreciate its newer roles we have discovered. Remember that it has an important place with our immune system, cancers, diabetes, and heart health; so speak to your family doctor or me at your next visit.
…..I hope everyone has survived the earthquake and Irene; my home lost power for five days, and it was not easy without the lights. Today we will finish up our discussion of vitamin D.
…..Vitamin D2 and D3 are changed in the liver to 25-Hydroxyvitamin D. That is the last time you will see that tough word since I will refer to it as 25(OH)D. This is what is measured in the blood, and it determines if we need to have extra vitamin supplementation. Vitamin D insufficiency is usually defined as a serum 25(OH)D level of 30 to 32 ng/ml.
…..In regard to calcium absorption, most studies suggest that with a 25(OH)D level of at least 20 ng/ml, there will be maximum absorption.
…..The daily recommendation for vitamin D is 600 IU for healthy non-pregnant women under 70 years of age and 800 IU for women older than 70 years.
…..Extra vitamin D should be added if the level is below 30 ng/ml. As a general rule of thumb, an extra 1000 IU per day of vitamin D3 will increase the 25(OH)D levels by 6-10 ng/ml. The levels should be checked after a three month trial.
…..Lastly, some studies point to problems if the 25(OH)D levels are greater than 50 ng/ml, so always check levels after adding extra vitamin D.
…..I cannot believe how fast the summer always seems to go. As August slips away, enjoy as much time as you can surrounded by family and friends. Now let’s go over who is at an increased risk for vitamin D deficiency.
…..People at an increased risk are those who have:
Dark skin pigmentation
Decreased sun exposure
Low intake of vitamin D
Poor absorption of ingested vitamin D
Been using antituberculosis and anticonvulsant medications, which increases breakdown in the liver of the vitamin
…..This past year has seen the discovery of vitamin D deficiency in a large portion of our population. In my office, we never measured the value before but now I speak about low vitamin D many times a day. Today you will be given some basic points, and over the next few blogs you will have a good understanding of the situation.
Vitamin D is important to maintain bone health.
Some studies have reported that being low on vitamin D can be related to heart problems, cancer, diabetes, and autoimmune disease. However, few true clinical trials have been taken.
Too much vitamin D should be avoided because of possible harm and lack of beneficial evidence.
The best measurement for the deficiency is the value of 25(OH)D in the blood. The supplementation of the vitamin should be given to reach a target 25(OH)D value.
