Mice lacking sufficient vitamin D develop osteoarthritis more rapidly than their age mates, but administering vitamin D anti aging supplements mitigates the progression of osteoarthritis.
Cells responsible for cartilage production, Chondrocytes, exposed to inflammatory molecules and treated with vitamin D exhibit reduced cellular aging and stress, which are known contributors to osteoarthritis development.
The observable decline in cellular aging and stress is likely because of the increased Sirt1 presence, an anti-aging and longevity protein, in cells treated with vitamin D.
Vitamin D supplementation effectively prevents knee osteoarthritis in elderly mice with vitamin D deficiency, primarily through its positive influence on the activity of Sirt1.
Researchers have made a significant breakthrough in understanding the potential role of vitamin D in preventing knee arthritis by its influence on anti-aging proteins, sirtuin proteins. In a recent study conducted on mice by medical universities in China and published in the International Journal of Biological Sciences, scientists observed that vitamin D deficiency accelerated the development of knee osteoarthritis in old and middle-aged mice. However, when these mice were provided with vitamin D3 supplementation, the progression of osteoarthritis was alleviated. Furthermore, the study highlighted the beneficial impact of vitamin D on chondrocytes, the cells responsible for cartilage production, where vitamin D treatment resulted in decreased cell aging and cellular stress, both of which are implicated in osteoarthritis development.
Vitamin D and Sirt1 Anti-Aging Properties
At the core of this mechanism lies the Sirt1 protein, well-known for its anti-aging properties. Vitamin D supplementation corrected the decreased Sirt1 levels observed in vitamin D-deficient mice. Sirt1 deficiency has been associated with increased spontaneous osteoarthritis while increasing Sirt1 levels have been linked to enhanced bone-forming cells and improved extracellular matrix production for maintaining tissue structure. Additionally, Sirt1 inhibits cell aging and the production of cells that promote inflammation and senescence, which can exacerbate and accelerate osteoarthritis.
Vitamin D3: Best Anti Aging Supplement
The study focused on two groups of mice, 6-month-old and 12-month-old, corresponding to 34 and 58 human years, respectively. Some of these mice were vitamin D deficient due to a lack of a specific protein responsible for converting inactive vitamin D into its active form. The vitamin D-deficient mice displayed more pronounced cartilage destruction, erosion, and extracellular matrix loss than the age-matched control group. The severity of osteoarthritis, as determined by the OARSI osteoarthritis scale, was also heightened in the vitamin D-deficient mice.
To explore the potential preventive effects of vitamin D as an anti-aging supplement, the researchers provided deficient mice with two types of rescue diets. One was high in calcium and phosphate (essential for bone formation but not affecting vitamin D levels). The other group received the same diet but supplemented with vitamin D3 injections 3 times per week at the age of 12 months. The mice treated with vitamin D3 exhibited reduced cartilage destruction and extracellular matrix loss. Their OARSI scores were also improved compared to the untreated deficient mice. Inflammatory signaling molecule levels and cartilage breakdown proteins were also diminished.
Vitamin D’s Protective Effects on Chondrocytes
Using human cell cultures, the researchers delved further into the underlying mechanisms of vitamin D’s effects on chondrocytes. Under inflammatory conditions, these chondrocytes showed increased vitamin D receptor proteins that facilitate vitamin D’s interaction with cells. Inflammatory molecules like IL-1β, used to induce proinflammatory conditions, have been implicated in osteoarthritis development due to increased cellular stress and senescence. Vitamin D supplements for anti aging protect the chondrocytes from the detrimental effects of the inflammation-induced reduction in viability and decreased levels of reactive oxygen molecules and senescence.
Unlocking Vitamin D’s Potential as an Anti-Aging Supplement
Further investigation unveiled that vitamin D3 treatment led to a time-dependent increase in Sirt1 protein levels. The vitamin D receptor interacted with genes involved in Sirt1 protein production, providing additional evidence of the connection between vitamin D and Sirt1. Vitamin D supplementation also hindered the accumulation of reactive oxygen molecules in chondrocytes, promoting proliferation and reduced cellular senescence. Additionally, increasing Sirt1 activity in mesenchymal stem cells, responsible for bone repair and replenishment, further demonstrated Sirt1’s role in preventing osteoarthritis development in vitamin D-deficient mice.
The study offers promising insights into the potential benefits of vitamin D as an anti-aging supplement for bone and cartilage health. Other studies have also underscored the value of vitamin D in promoting healthy aging.
Insufficient vitamin D has been associated with faster aging due to its impact on epigenetics and gene expression. Vitamin D, when combined with exercise and omega-3 supplementation, may lower cancer risk. Yet, more research is needed to grasp its long-term effects on overall health as people age.
