The Truth About Vitamin D Synthesis

Most people believe that simply soaking up the sunlight allows our skin to synthesize Vitamin D, eliminating the need for additional supplementation. However, this notion is contradicted by the fact that during summer, many turn to sunscreen to protect their skin from the sun. Furthermore, given the predominantly indoor lifestyle, opportunities to experience direct sunlight are limited. The question arises: Can we really produce sufficient Vitamin D solely by basking in the sun's rays? Recent observations in our clinic indicate that a significant number of patients have Vitamin D levels below 20. This issue is particularly pronounced among women. Even I, despite taking Vitamin D supplements, have struggled to achieve desirable levels.

I recently returned from a family trip to California, San Diego. While staying near the beach, I enjoyed various outdoor activities and gained a sun-kissed complexion. Living in New York and New Jersey, I rarely found myself in spots with ample sunlight due to the abundance of indoor spaces and office work. This disparity implies that the amount of Vitamin D generated by one hour of sun exposure in equatorial regions differs from that in other places. Therefore, the reliability of Vitamin D acquired from sunlight can be inconsistent. My Vitamin D levels have consistently remained below 20. However, a recent routine checkup revealed a surprising change – my Vitamin D levels had normalized. I maintained a steady intake of 5000 IU and spent more time outdoors. This raised the question: Why did my Vitamin D levels improve? The answer lies in the significance of maintaining adequate levels of Vitamin D in the bloodstream. Extensive research suggests that higher Vitamin D intake and elevated blood levels can aid in preventing conditions such as hypertension, heart attacks, influenza, osteoporosis, and various cancers.

It's common to encounter patients with low Vitamin D levels in their regular checkup reports. However, a concerning trend is the increasing acceptance of low Vitamin D levels as a norm. Nowadays, patients easily dismiss the importance of maintaining optimal levels. Additionally, in my clinic, there has been a noticeable rise in young women aged 30-40 seeking treatment for breast cancer. This emphasizes the need to address health issues highlighted in blood tests to actively work towards a healthier recovery.
