Calcium and Vitamin D for bone density

Posted by ellerbracke @ellerbracke, Oct 1, 2019

A recent bone density test came back in the low average range for my age. My OBGYN recommended calcium and vitamin D. I checked with a family member who is a pharmacist, and she says that the benefits of calcium supplements are not clear cut. Regarding vitamin D, I’m in the sunbelt, and spend at least 2 hours per day outdoors during 8 to 9 months a year (early morning, or evening, sun screen between 10 AM and 5 PM if applicable for pool, beach, for example). I’m sure many people on this forum have done their own research regarding the benefits of calcium pills, and I would love to hear what the current consensus is. I exercise regularly, so my bones get a workout from the muscles pulling on them, if that makes a difference. I think the data I was given is that statistically I have an 8% chance of a hip fracture in the next decade, based on the test results.

Hi @callalloo I studied the Whole Body Vibration Machines on Amazon and bought the Eilison Bolt. It is 11 lbs., a light weight that I can move fairly easily, has a five year warranty and three programs for building bone density (they claim). (With osteoporosis, the directive is don't lift more than 20 lbs.) The Bolt also works on carpet with a yoga mat placed underneath it. I've been doing two 15 minute bone density programs twice a day since August. So far, it's firmed my muscles. I won't be eligible for another Dexa scan for a year, and most studies of whole body vibration machines put participants with low bone density on them for two 15 minute sessions five times a week for a year, so if it does work, it will take time. After I gave up my weighted vest, I made a weighted belt with two one pound ankle weights and one 2.5, but my rheumatologist said that could cause spinal fractures so I gave up pursuing anything along those lines.

Thanks, Teri. I'm going to get one and try it. At the least, it sounds like, we'll, fun or relaxing. It'll be great if your next DEXA shows improvement. And if it shows no change, that is improvement, reversing a trendline.

I understand that walking is a weight bearing exercise. Any more opinions on that?

Yes it is a weight bearing exercise. When your feet his the surface it causes bone to get stronger. I am sure thre is a more scientific explanation but this is the simple version.

I agree, @callalloo. I'll keep my fingers crossed.

Please let us all know. TU.

Margaret Martin, who does writing and videos on osteoporosis,addresses vibration machines on her Melio guide. I have been leery of such things because my spine is so fragile and that is a consideration. There are other contraindications as well. Apparently higher frequencies/magnitude are actually dangerous and can affect the brain, but at the frequencies/magnitude you are all using the machines are safe in that regard. Here is her post on vibration machines https://melioguide.com/osteoporosis-exercise-equipment/whole-body-vibration-therapy/

I would be scared of the effect on my spine fractures, migraines, and on my afib. as well as any potential dizziness/inner ear effects. Here is the content of Martin's post on contraindications (she also had a longer post on studies, regarding benefits as well as dangers):

Whole Body Vibration Therapy Plate Contraindications
Registered equipment manufacturers have identified a number of whole body vibration therapy contraindications and suggest that individuals who have one of the following conditions should not partake in WBV training:

Kidney or bladder stones.
Arrhythmia.
Pregnancy.
Epilepsy.
Seizures.
Cancer.
A pacemaker.
Untreated orthostatic hypotension.
Recent implants (joint/corneal/cochlear, etc.).
Recent surgery.
Recently placed intrauterine devices or pins.
Acute thrombosis or hernia, acute rheumatoid arthritis.
Serious cardiovascular disease.
Severe diabetes.
Migraines.
Among individuals with spinal cord injury (SCI), several adverse events were reported including pain, pressure sores on the feet, autonomic dysreflexia, and dizziness, which were largely attributed to the passive standing portion of the intervention.

Researchers at Lyndhurst Centre caution that Whole Body Vibration may elicit inner ear troubles, dizziness, headache, lower-limb spasticity, fracture (especially among those with severe osteoporosis), and/or hardware loosening (plates or screws as a result of surgery).(19)

A recent systematic review and meta-analysis on the effects of Whole Body Vibration on BMD in postmenopausal women concluded that Whole Body Vibration slows down bone loss at the hip (20) the benefits are similar to walking.

I take Citracal petites, half dose in morning and again at night. The rest of my calcium comes from low sodium cottage cheese, yougurt, and salmon with bones.

I was advised by a hospital dietitian not to take calcium supplements as they can cause calcium buildup in the arteries, and do not absorb as well as calcium in your food. I did an internet search and found a news release by E. D. Michos, M.D., Director of Women's Cardiovascular Health at Johns Hopkins, in which she advised against calcium supplements. Further searches came up with both for and against. I judge the most helpful summary of the controversy to be a Cleveland Clinic discussion, which cites Leslie Cho, M.D., Director of the Cleveland Clinic’s Women’s Cardiovascular Center. https://health.clevelandclinic.org/can-too-much-calcium-raise-your-heart-attack-risk

@ellerbracke @candrgonzalez What test shows Vitamin D level? I have a battery of tests every month because I am post-transplant and I just went through them. I do see calcium there, in the Comprehensive Metabolic Panel. Mine is 9.1 mg/dL and the range is 8.6 - 10.4 mg/dL so I am within that but I do not see Vitamin D anywhere. According to the DEXA I had a few weeks ago I have somewhat severe osteoporosis so this is a very concerning thing for me. I have an appointment with an osteoporosis specialist (an endocrinologist) but it's not until January so until then I want to be as proactive as I can be.
Thanks.

This is an old post, and since you were scheduled to see an osteoporosis specialist, by now you most certainly have been tested for Vitamin D deficiency. I just want to comment that insurance companies do not pay for Vitamin D tests UNLESS there is a diagnosis of Vitamin D deficiency, and it is never included in a Comprehensive Metabolic Panel. If anyone is wanting a test, perhaps you should request it and advise the doctor to show a diagnosis of "suspected Vitamin D deficiency." That should be enough to get your insurance to pay for it. A number of years ago, I was advised to take 5,000 units Vitamin D just because that's "what most people need." At the time I was walking daily in full sun and taking a calcium supplement. My calcium test went off the chart, and I had to quit both D and calcium. Several years later my lifestyle and location changed, and I decided to test for Vitamin D, a test my doctor at the time thought was unnecessary. I paid for my own test using an internet-based testing service called Canary Club, which showed a deficiency. Because of my previous experience, I began taking a small dose and gradually increased it after each test that showed I was still deficient. I am currently at 4,800 units and test as low normal. So I will go ahead and increase to 5,000 units, since that is available in a single standard capsule. Since that first test showing deficiency, insurance has covered my annual Vitamin D test. My current doctors all think annual testing is a good idea.

According to my doctors ans sheet logic, of course it is. Your legs are 'bearing' the full weight of your body with every step. Wearing a weighted vest, or carrying something heavy, can recall certain the load on other muscles but, if the person is also walking, the legs are bearing the weight. When I first started reading about osteoporosis, I came upon a study as to why professional cyclists tend to have early-onset, and severe, osteoporosis. The conclusion was that they frequently run a calorie deficit to lower body weight. And they spend training time on cycles. So they don't have body fat, thus also lower estrogen, to help bone health. And their lean frames are insufficient to make walking a good weight-bearing exercise.
