Vitamin D Receptors in muscles decrease with age in those with Osteoporosis - 2018

Vitamin D Receptor in Muscle Atrophy of Elderly Patients: A Key Element of Osteoporosis-Sarcopenia Connection

Aging and disease ›› 2018, Vol. 9 ›› Issue (6) : 952-964. DOI: 10.14336/AD.2018.0215

In this study, we investigated the relationship between sarcopenia (evaluated in term of fibers atrophy), vitamin d receptor protein expression and TaqI/Cdx2/FokI VDR genotypes in an Italian cohort of osteoporosis(n=44) and osteoarthritis (n=55) patients. Muscle biopsies were fixed and investigated by both immunohistochemistry (vitamin d receptor expression) and transmission electron microscopy (satellite stem cells niches). Vitamin d receptor polymorphisms were studied on DNA extracted from muscle paraffin sections. For the first time, we reported that aging differently affects the VDR activation in OA and OP patients. In particular, while in OP patients we observed a significant reduction of VDR positive myonuclei with age, no “age effect” was observed in OA patients. The frequent activation of VDR could explain the lower number of atrophic fiber that we observed in OA patients respect to OP. From genetic point of view, we showed a putative association among polymorphisms FokI and Cdx2 of VDR gene, vitamin d receptor activation and the occurrence of sarcopenia. Altogether these data open new prospective for the prevention and cure of age-related muscle disorders.

VitaminDWiki – Overview Osteoporosis and vitamin D contains

  • FACT: Bones need Calcium (this has been known for a very long time)
  • FACT: Vitamin D improves Calcium bioavailability (3X ?)
  • FACT: Should not take > 750 mg of Calcium if taking lots of vitamin D (Calcium becomes too bio-available)
  • FACT: Adding vitamin D via Sun, UV, or supplements increased vitamin D in the blood
  • FACT: Vitamin D supplements are very low cost
  • FACT: Many trials, studies. reviews, and meta-analysis agree: adding vitamin D reduces osteoporosis
  • FACT: Toxic level of vitamin D is about 4X higher than the amount needed to reduce osteoporosis
  • FACT: Co-factors help build bones.
  • FACT: Vitamin D Receptor can restrict Vitamin D from getting to many tissues, such as bones
  • It appears that to TREAT Osteoporosis:
  •        Calcium OR vitamin D is ok
  •        Calcium + vitamin D is good
  •        Calcium + vitamin D + other co-factors is great
  •        Low-cost Vitamin D Receptor activators sometimes may be helpful
  • CONCLUSION: To PREVENT many diseases, including Osteoporosis, as well as TREAT Osteoporosis
  • Category Osteoporosis has 221 items
  • Category Bone Health has 314 items

Note: Osteoporosis causes bones to become fragile and prone to fracture
  Osteoarthritis is a disease where damage occurs to the joints at the end of the bones

VitaminDWiki – Osteoporosis category contains

VitaminDWiki – Muscles and Vitamin D - many studies contains

To build muscles you need more than just Vitamin D
   also need Exercise, Protein, Magnesium, Omega-3, and activated Vitamin D Receptors
     In fact, Vitamin D monotherapy sometimes DECREASES muscles.
Notes on Vitamin D Receptor:
Vitamin D Receptors get vitamin D in the blood to the muscle cells
Approximately 20% of people have poor vitamin D receptors
As people age, their Vitamin D receptors also become less activated
There are 12+ low-cost activators for the Vitamin D Receptor

Dr. Greger on Vitamin D and Muscles - May 2020
Vitamin D Supplements for Increasing Aging Muscle Strength

  • "We have known for more than 400 years that muscle weakness is a common presenting symptom of vitamin D deficiency"
  • conservative "U.S. Preventive Services Task Force, the official prevention guideline setting body, and the American Geriatric Society to “recommend vitamin D supplementation for persons who are at high risk of falls.”
  • AGS recommends 4,000 IU to capture 92 percent of the population"
