Live In A City? Your Vitamin D Levels May Be Suffering + How To Get Enough

Science continues to confirm something humans have intuitively known for quite some time: Being in nature is good for our health. 

And while the effect of green and blue spaces on our mental well-being, sleep health, and cognitive function have been established for some time now, scientists have recently started investigating how environmental factors directly impact vitamin D status. 

In a new Environment International (EI) study, scientists in China examined the correlation between residential greenness, air pollution, UV radiation, and vitamin D levels in adults over the age of 65. Using data from the 2012 and 2014 Chinese Longitudinal Healthy Longevity Survey and environmental exposure measurements from the same years, they found that the health of our environment does, indeed, play a role in our vitamin D status.

During the Environment International study, residential greenness (i.e., the amount of natural vegetation surrounding a person’s home) was found to decrease the likelihood of VDD.

UV radiation was also found to decrease the likelihood of VDD. And while it’s true that increasing your sunlight exposure can raise your vitamin D levels, there are many other factors at play—such as age, sex, skin tone, latitude, climate, season, and time spent outside with skin exposed. 

Evidence the vitamin D endocrine system (VDES), which modulates vitamin D skin synthesis and metabolism, is affected by exposure to environmental chemicals and air pollution. Air pollutants—specifically, PM2.5 (inhalable air pollutants that can travel deeply into your lungs) and ozone (O3)—were found to increase the likelihood of VDD during the EI study. 

Sunshine isn’t a reliable source of vitamin D for most people in most climates around the world. Food isn’t a great solution either, considering vitamin D is found in minimal amounts in most dietary sources.

The truth is this: Supplementation is the most efficient way to reach healthy vitamin D status.* That said, not all vitamin D supplements are created equal.

Look for a daily supplement with a high-potency dose (5,000 IU) of vitamin D3 (not D2) and built-in healthy fats (for optimal absorption). mbg’s vitamin D3 potency+ has you covered on all accounts.

Vitamin D deficiency is a global problem, and environmental health impacts healthy vitamin D status. According to a new study from Environment International on older adults in China, the likelihood of VDD is negatively correlated with residential greenness and UV radiation, but positively correlated with air pollution.

To ensure your vitamin D status reaches and sustains sufficiency no matter where you live, consider taking a quality, high-potency vitamin D supplement like mbg’s vitamin D3 potency+.*
