You may have heard in the new recently, that a recent study on Vitamin D did not show any benefit for bone health in post menopausal women.
I want to point a few things out however, before you stop your supplement, thinking it is not doing any thing.
- This study was done in a small group of women.
- It only last 1 year.
- It compared women taking 800 IUs of Vitamin D3, and those taking 50,000 IUs of Vitamin D3, and women taking a placebo.
The study did show there was greater absorption of calcium in the high dose supplement group, but it did not show any increase of bone density or muscle mass. Additionally, the sit-to-stand test was also unchanged.
It is important to understand that this study was only done for a year, and this may very well not be long enough to see a change of bone density. And it was done on a small sampling of women.
It is also important to understand that levels of Vitamin D above 30 ng/ml is felt to have benefit for muscles, brain, colon. You may not need 50,000 IUs, but I still adhere to a daily 2,000 IU tablet.
It does seem that small studies are released regularly with conflicting information. What is important to remember, is that we need strong bones that won’t break when we fall. We need strong muscles to give us strength, stability and balance; to help prevent us from falling.
We can accomplish this with a diet high in calcium and Vitamin D, supplement when our diet is lacking these important nutrients. And we can further help ourselves by exercising both aerobically for our hearts, and strength training for our strength and balance.
Dr. Sue Ellen Cox, pictured to the left, is a board certified Dermatologist practicing dermatology in Chapel Hill, NC. She is one of the founding partners of Aesthetic Solutions and contines to be a managing partner in that practice. She is also an Associate-Professor of Dermatology at the University of North Carolina Chapel Hill Medical Center. Drl Cox was interviewed in her home and some family interaction is evident during the interview.
During her talk with Anne Vaillancourt PAC, she discusses the following topics:
Adult Acne, Dry Skin, Winter Itch, Eczema, Nummular Eczema, Hand dermatitis, Thyroid disorder as a cause of itching, Vitamin D, Wrinkles fine lines and the causes of them, Treatments for aging skin, Rosacea, skin cancer, basal cell, melanoma
Drugs she discusses are:
Spironolactone for adult acne
Atopiclair for eczema and very dry skin
Mimyx cream for eczema and very dry skin
UVA and UVB sunscreen – pay attention to her explanation of SPF as applicable to UVB only – UVA rays do the damage so pay attention there.
Titanium Dioxide, Zinc Oxide, Mexoryl,
Metrogel topical cream (not to be confused with the vaginal variety)
Revale, Aczone, Finacia all mentioned along with Pulsed dye laser all for Rosacea
for skin cancer PDT or photo dynamic therapy, immune modulators like Aldara, Mohs micrographic surgery,
From the University of Washington comes the info I present on this 5 minute video on Vitamin D3 or Cholecalciferol. It is called the sunshine vitamin. You will see why in the video. Problem is most of us do not get enough sun, some of use due to age (>70) don’t make it well and some of us have pigmented skin so we need more time in the sun to make adequate amounts.
This video should answer some questions for you:
- How do I know if I have enough Vitamin D?
- What do you measure to find out?
- How much should I take?
- How is Vitamin D made within my body?
This article was published previously but I thought you would benefit from reading it.
Vitamin D3 is something we can make in our skin and use in many different cells within our body. The problem is that many of us do not get the hour of prime-time sunshine we need per week. Even when we are sun exposed, many of us are wearing sun screen, have pigmented skin that decreases our production or are advanced in age and even with enough sun, may not produce enough Vitamin D. This article is to help you understand the benefits of Vitamin D3 so you will be motivated to take a supplement and to possibly have your 25 OH vitamin D levels checked.
The 12 benefits of adequate Vitamin D3 (CHOLECALCIFEROL) are easily identified from the medical literature. These benefits appear in enough different places that it can be assumed the studies are valid.
- Adequate levels of Vitamin D3 protect against Breast Cancer. One problem with cancer cells is that they don’t destruct when they are supposed to. They keep dividing and reproducing. Vit. D receptors are present on most cells in our body and help to trigger appropriate cell death, and identify to the immune system the correct cells it should eliminate.
- Ditto for Cancer of the Colon (large bowel). Both colon cancer and breast cancer are increased in people of color. The same people most likely to have lower levels of Vitamin D3 in their blood. People who have more pigment in their skin need 30% more sun exposure to produce enough cholecalciferol. Anyone and especially dark skinned individuals need to supplement if they live in northern latitudes that have more months of reduced sunshine per year.
- Vitamin D regulates absorption of calcium and phosphorus which are needed for healthy bones. Low levels of D3 are associated with poor bone development in children and bone softening in adults called osteopenia if mild or osteoporosis if advanced.
- Vitamin D3 is associated with proper immune function. It is no coincidence that the “cold season” is during winter months when there is less sunshine.
- The Brain’s health is dependent upon a number of factors and one of them is adequate levels of Vitamin D3.
- Keeping adequate levels of Vitamin D3 in our blood and tissues is associated with decreased aging changes in our body. Want to keep your vitality longer? Make sure you get enough Vitamin D in your diet or enough sunshine in your life.
- Certain female gynecologic infections are associated with inadequate blood levels of Vitamin D3. Bacterial Vaginosis is the most common of these and hardest to control. If you have vaginitis and it won’t clear, check your 25OH Vitamin D blood levels.
- Insulin is a very important hormone but it can be over or under secreted. Vitamin D helps regulate insulin secretion.
- Many patients, especially women complain of joint pain and fatigue. Some of them have been given the diagnosis of Fibromyalgia. Inadequate blood levels of D3 are associated with these aches, pains and fatigue. Get your 25OH vit D levels checked or take a therapeutic trial of 1000IU/day and keep a journal of your symptoms.
- Auto-immune disorders wreak havoc with tissues in our body. Common diseases that are caused by auto immune dysfunction are diabetes, rheumatoid arthritis, and hypo-thyroidism. Adequate levels of Vit. D3 in the blood and tissues decreases the risk and severity of such diseases.
- Hypertension is associated with inadequate blood and tissue levels of several minerals and vital substances like potassium, calcium, selenium, and you guessed it Vit. D3.
- Vitamin D3 if kept at adequate levels in the blood is associated with a decreased risk of death from any cause. It isn’t a panacea, but it obviously plays a more important role in our health than was realized for any years.
