Vitamin D And Longer Lifespan

Many people associate vitamin D and longer lifespan with each other, as most of us have grown up being told that vitamins are vital to keep us healthy. However, it appears that many people do not realise just how important it really is, as multiple studies show that roughly 50% of people have vitamin D levels below the optimal range, and around 20% have a vitamin D deficiency.

The simple fact is, if you want to live a long and healthy life, you need to keep your vitamin D levels in the healthy range. That is why we have written the following article on the link between vitamin D and longer lifespan. We will show you exactly how and why it is so important to maintain optimal vitamin D levels, and hopefully convince you to take action and up your intake, before it’s too late.

What Is Vitamin D?

Vitamin D is an essential, fat-soluble vitamin also known as cholecalciferol and “the sunshine vitamin”. It is needed for many functions in the human body to occur, with studies showing that an average person needs at least 10 to 20 mcg of vitamin D a day for their body to maintain optimal health and functions (1).

Present in countless foods, drinks, and supplements, getting enough vitamin D daily offers many health benefits. We will now analyse those that can help improve a person’s lifespan and help them live longer.

Vitamin D And Longer Lifespan: How Can Vitamin D Help You Live Longer?

Provides Immune System Support

Vitamin D is vital for the immune system, especially the innate immune system, which is the body’s first line of defence. Vitamin D receptors (VDRs) are present on almost all immune cells, so vitamin D is needed to activate them and enable them to fight pathogens.

It regulates the function and production of various key immune cells vital in detecting and responding to these pathogens and other foreign invaders. This is while aiding the production of antimicrobial peptides that help protect the body from pathogens by disrupting the cell walls of bacteria and viruses.

It also prevents parts of the immune system from becoming inflamed, which stops it from working properly. It also ensures it doesn’t become overactive, which can lead to autoimmune diseases and the immune system attacking the body’s own cells and healthy tissue and doing more harm than good (2).

Reduces The Risk Of Chronic Conditions

Maintaining healthy vitamin D levels can also reduce the risk of many chronic conditions, such as heart disease, cancer, and diabetes, all of which will dramatically shorten a person’s lifespan.

Low vitamin D levels are associated with higher blood pressure, arterial stiffness, and inflammation, all of which are risk factors for heart disease. Studies suggest sufficient levels of vitamin D may lower the risk of heart attacks, stroke, and even heart failure.

Vitamin D may also help to regulate cell growth and differentiation, reducing the risk of certain cancers, especially colon, breast, and prostate cancer. It may also slow tumor growth by inhibiting angiogenesis, which is the formation of new blood vessels that feed tumors (4).

Finally, vitamin D helps with Type 2 Diabetes as it improves insulin sensitivity, and it supports pancreatic beta-cell function, which potentially reduces the risk of you developing type 2 diabetes in the first place.

Supports Bone Health & Density

Vitamin D helps you maintain optimal bone health, strength, and density by supporting several essential processes involved in bone growth and maintenance.

It aids the absorption of calcium and phosphorus, the main minerals in bones, improving their strength and form and preventing weakness. It then also stimulates osteoblast activity, promoting bone growth and repair, and reducing the activity of osteoclasts, which break bones down.

Its anti-inflammatory properties will then help to prevent issues with the joints. This reduces damage to the bones directly while stopping people from becoming sedentary, which can impair bone strength and negatively impact many other aspects of a person’s mental and physical health.

This all ensures that your bones remain stronger and denser as you age, reducing the risk of fractures and conditions like osteoporosis and osteomalacia, which can lead to falls and other conditions that put your health and life at risk (6).

Improves Brain Health & Functions

Vitamin D improves brain health and functions through multiple pathways. Beyond its neuroprotective properties that protect the brain from damage, inflammation, and oxidative stress, it also stimulates neurogenesis, which promotes the growth of new neurons, and improves neurotransmitter production.

This will allow you to enjoy better mental clarity and functions, and improved mood, memory, focus, and learning as you age. It will also help repair any damage that has already occurred and prevent mental decline, memory loss, and conditions like Alzheimer’s disease, Parkinson’s disease, dementia, and MS (multiple sclerosis).

As many people experience a loss of mental functions as they age, which causes various life-threatening issues, maintaining your brain health and functions is essential if you want a longer lifespan (7).

Enhances Telomere Preservation (Cellular Aging)

Some studies suggest that higher vitamin D levels are associated with longer telomeres, which are the protective caps found on chromosomes linked to biological aging and lifespan in humans. By extending these caps, it is believed that you can directly slow the aging process of the cells themselves.

This would lead to you aging at a lower rate, both internally and externally, and directly increase the likelihood of you living a longer life (8).
