Our bodies are delicate machines that work tirelessly from the day we are born till the day we die. The human body goes through several changes as we grow older. When we hit the 40-year mark, several aspects of our body mechanics change in the following ways;
Metabolism: The efficiency at which our body produces energy becomes reduced from 40 and above. Our metabolism slows down significantly at this age
Increased bone fragility: As we age, our bones loose calcium and other minerals, which contribute to bone fragility and osteoporosis.
Muscle loss: Loss of muscle and deteriorating muscle function actually starts when we hit 30. The process is called Sarcopenia, its effects are felt more severely when we hit 40.
Weakened joints: Joints begin to lose their flexibility; this is usually a precursor to osteoarthritis which is the breakdown of the cartilage that lies in between bones.
Brain Fuzziness: Your ability to remember tiny details becomes diminished as you age, it usually occurs as a result of hormonal changes.
Cardiovascular changes: Your arteries begin to stiffen and harden at 40, at this age also, many people are prone to having more irregular heartbeats than before. High blood pressure is also more likely to occur and heart enlargement also becomes more of an issue.
Weaker immune function: Your body begins to lose the agility of its immune function as we grow older, making us more prone to diseases and infections. For women over 40, there is an increased tendency for UTI’s as estrogen production reduces.
IMPACT OF VITAMIN D3 ON AGEING
Older adults are at risk for lower levels of vitamin D as a result of decreased cutaneous synthesis and dietary intake of vitamin D. Epidemiologic evidence indicates an association between low levels of vitamin D and diseases associated with aging such as cognitive decline, depression, osteoporosis, cardiovascular disease, hypertension, type 2 diabetes, and cancer.
Vitamin D also helps to relieve many of the untoward symptoms of ageing; it helps to strengthen bones leading to fewer fractures. Vitamin D also helps to improve mood and energy levels which can take a hit as we age. For heart health, Vitamin D is essential as it helps regulate calcium absorption in the body. It is of note to mention that excess blood calcium levels can lead to arterial stiffening which is a very important cause of cardiovascular issues. A little know vitamin K2 helps to direct calcium from the blood to the bones and teeth where it is needed.
Vitamin D deficiency has been associated with muscle loss and atrophy, at the cellular level, Vitamin D deficiency impairs intracellular calcium kinetics and muscle cell contractility.
Lately, Vitamin D3 has also been shown to improve the immune system more so with its impact on COVID-19 patients.
