Vitamin D plays an important role in the regulation of calcium and phosphorus absorption by an organism. It also helps keep the brain and immune system working. Researchers have now shown that vitamin D supplementation reduces the risk of dynapenia in older people by 78%.
Dynapenia is an age-associated loss of muscle strength.
"Vitamin D is known to participate in various functions of the organism. It’s a hormone and roles include helping to repair muscles and releasing calcium for muscle contraction kinetics," said Tiago da Silva Alexandre.
Bone and muscle tissue are interconnected not just mechanically and physically, but also biochemically. "Endocrine disorders such as vitamin D deficiency or insufficiency can lead to loss of bone mineral density as well as a reduction in muscle mass, strength and function," he said.
The main conclusion was that individuals with vitamin D deficiency, defined as less than 30 nanomoles per liter in the blood, had a 70% higher risk of developing dynapenia by the end of the four-year study period than those with normal levels of vitamin D, defined as more than 50 nmol/L.
"This is an important finding as it shows that vitamin D deficiency heightens the risk of muscle weakness by 70%. However, because we knew there are many worldwide cases of people with osteoporosis who take vitamin supplements, we needed to measure the effectiveness of vitamin D supplementation," said Maicon Luís Bicigo Delinocente.
When individuals with osteoporosis and those taking vitamin D were excluded from the analysis, he explained, "we found that the risk of developing muscle weakness by the end of the four-year period was 78% higher for subjects with vitamin D deficiency at the start of the study than for subjects with normal vitamin D levels, and 77% higher for those with vitamin D insufficiency [30-50 nmol/L]."

Good catch. The ones I take are indeed softgels, not tablets.
I wrote that post on a tablet, if that counts!
Oh, and I read studies, too..and do appreciate your posts..dont get me wrong. I just found it interesting about the study of “studies”...I was doing research on PEMF...my newest fascination
>year ago my PCPhysician told me I was at low end of normal for VitD. Took a 50mcg pill daily. Am now at high end of normal.
It’s ‘cause I don’t get enough sun. Period. If I had the leisure time to sit about in the sun I’d not take the pill.
Just take a pill and quit worrying. BTWay, sufficient VitD also helps fight flu (e.g., like WuhanFlu).
“I wrote that post on a tablet, if that counts!”
sure, why not? :-)
“I wrote that post on a tablet, if that counts!”
It does not count. Tablets are for children. Get a 17.3” laptop. Or use a computer with a 24” monitor display/ I have used and own 27”and 32” monitors on the same computer, but I prefer 24”. To those who give a ____ this computer is i5-8400, 16gb mem/ a 512gb NVME drive
Dude, I have 3 tablets, 4 PC computers, a Dell PowerEdge R610 Server with 192GB RAM and 8 Terabyte HD, and 2 540 SSDs, and two iPhones.
I write Micrsoft Server and Sys Admin courseware for a living, so I need all this stuff. I got more pc’s I use as servers, but they’re turned off until needed.
lolsss You are fully stocked up and stacked up.
Is it cause? Or effect? For example, people getting outdoors are likely to have higher vitamin D levels. People getting outdoors are more active and more likely to DO things compared to those who spend their older years inside.
Not saying supplementing with Vitamin D is bad. I think it makes a lot of sense to supplement SOME. Not mega-doses, but maybe 1-2,000 IU. Cost pennies and seems to have a lot of good results associated with it and almost no down side.
But like most studies I see now, the study design and results aren’t evidence of anything.
Vitamin D can also put calcium into arteries, a bad thing. Lots say to supplement D with K2 to stop that.
You dont’t need to supplement with vitamin k if you don’t take excess vitamin d.
