Our body’s ability to produce vitamin D declines with age. As you age, you should anticipate becoming progressively deficient in the vital nutrient due to a combination of changing lifestyle choices.
However, the unexpected finding from a study of more than 30,000 participants was that young individuals’ vitamin D levels were lower than expected.
What caused this to occur? And how can it be addressed?
In this blog, we will cover:
- Why does the production of vitamin D decline with age?
- Why are young adults at higher risk of low vitamin D levels?
- The consequences of vitamin D deficiency in young adults
- What can young people do to improve their vitamin D levels?
Why Does The Production Of Vitamin D Decline With Age?
Our skin contains specific compounds known as 7-dehydrocholesterol, or 7DHC. The 7DHC molecules absorb sunlight and get energized when it strikes our skin. To adapt to their new vitality, they must first reorganize themselves into pre-vitamin D3.
Pre-vitamin D3 is changed into vitamin D3 by the heat from our bodies, which may then exit the skin and enter the bloodstream. It then travels to the kidneys and liver, where it is converted into usable forms.
1. Skin Concentration
As we age, our skin’s 7DHC levels are believed to drop by as much as 50% by the age of 70. Vitamin D deficiency treatment Dubai becomes increasingly relevant here, as research indicates that older skin produces half as much vitamin D as younger skin.
2. Metabolic Changes
The body’s ability to handle calcium and vitamin D is diminished by metabolic changes, especially those that affect the liver and kidneys. Low Vitamin D treatment Dubai professionals often address these metabolic shifts as a core part of managing deficiency in older patients.
3. Lifestyle
Age-related changes in lifestyle also have an impact on vitamin D production or absorption, including:
- Medication or illness-induced decreased appetite: Individuals are less likely to consume enough food to meet their vitamin D needs.
- Reduced mobility as a result of weaker muscles: In addition to increasing sun exposure, exercise has indirect benefits such as better bone health and vitamin D metabolism.
- Living in residential care or becoming housebound: It makes it harder for some elderly people to get outside in the sun when they wish to, which raises their risk of deficiencies.
Why Are Young Adults At Higher Risk Of Low Vitamin D Levels?
According to an annual data study, 23.8% of people aged 18 to 30 have inadequate vitamin D levels. On the other hand, 10.2% of individuals over 60 had deficiencies. This indicates that, contrary to expectations, younger persons were more than twice as likely to have low vitamin D as older adults.
Further investigation revealed that this was not an anomaly. Young individuals often report lower vitamin D levels than older adults, according to a study in which data collected over the past six years.
Unsurprisingly, the two primary causes of the younger generation’s lower vitamin D levels are modern lifestyle and urban living. These consist of:
1. An indoor lifestyle
According to regional studies, fewer than 25% of 17–23-year-olds in the UAE reported spending regular time in outdoor spaces or parks. More than 75% of young people in Dubai spend more time indoors than outdoors — a pattern that directly contributes to vitamin D deficiency. Addressing this requires a comprehensive approach; nutritional deficiency treatment Dubai focuses not just on supplementation, but on identifying the root lifestyle causes behind declining levels in younger populations.
Additionally, students study indoors for most of the day. However, even if you study near a window, the glass will still block useful UVB rays.
Furthermore, you have to commute to work unless you’re working remotely, which is most likely indoors. For many, this means spending commuting by car or on public transportation, which further limits their exposure to the sun.
The majority of us spend excessive amounts of time on our phones, and the popularity of screens likely contributes to our indoor time. Many young people prefer indoor screen-based activities over outdoor pursuits.
With TV series and games becoming more engaging and addictive, screen-based technology is more pervasive than ever.
2. Dietary options
Some vitamin D can be obtained through diet by consuming foods high in nutrients. Endocrinologist for Vitamin D issues Dubai practitioners often recommend dietary adjustments as a first step, including:
- Fatty fish, such as mackerel, herring, tuna, and sardines
- Egg yolks
- Mushrooms, particularly those cultivated outdoors
- Fortified cereals and milk
3. Low budget
Fast food and highly processed foods can lead to low vitamin D levels, and students are known for maintaining poor diets. Vitamin D injection Dubai options are sometimes explored for individuals whose dietary intake remains consistently poor despite awareness. A lack of cooking abilities is another problem that keeps young people from eating nutritious meals, although having a limited budget is also a contributing factor.
4. Poverty
While Dubai is known for its high standard of living, economic disparity does exist. A significant portion of Dubai’s population consists of low-income workers, particularly those in the construction, hospitality, and service sectors, who may struggle to afford a nutrient-rich diet regularly.
Vitamin D-rich foods such as fresh fish, eggs, and fortified dairy products can be costly, making them less accessible for those on tight budgets. Highly processed and fast foods, which are far more affordable, contain little to no vitamin D — creating a nutritional gap that is easy to overlook.
For those in lower income brackets, vitamin D replacement therapy Dubai may feel out of reach without proper guidance. However, affordable screening and treatment options are available through Dubai Health Authority (DHA) facilities, making it important for all residents — regardless of income — to be aware of the support accessible to them.
5. Avoiding meat products
The majority of vitamin D comes from animal products, even though plant-based diets are often healthful in many respects. Although mushrooms and humans both create vitamin D, many of the mushrooms found in shops are produced indoors.
The best source of mushrooms is found in the wild, but wild mushrooms should only be consumed if identified as safe by an expert.
6. Geographical factors
The UAE is well-known for its abundant sunshine, yet many young residents still struggle with low vitamin D levels. So how is this possible?
Despite the intense sun, several environmental factors unique to Dubai limit effective UVB absorption. The city’s high-rise buildings and dense urban landscape create shaded corridors that significantly reduce direct sun exposure. Additionally, Dubai’s notorious summer heat — with temperatures regularly exceeding 45°C — forces most residents indoors for months at a time, making meaningful sun exposure difficult from June through September.
Fine dust and sandstorms can also scatter and block UVB rays, reducing the skin’s ability to synthesize vitamin D even on otherwise sunny days. For those in high-pollution urban environments, IV therapy for vitamin D Dubai may be considered when sun exposure alone is insufficient.
7. Lack of awareness
Young individuals might not even be aware that they are at risk until they begin to exhibit signs of deficiencies. Vitamin D test Dubai facilities make early screening simple and accessible, which is especially important for young adults who show no obvious symptoms yet. Even though health experts may urge the elderly to monitor their vitamin D levels or take a supplement, younger people are often overlooked.
The Consequences Of Vitamin D Deficiency In Young Adults
Vitamin D is essential at every stage of life, but deficiency during early years can have lasting consequences.
Weakened immune system
Vitamin D levels below 75 nmol/L may weaken the immune system and increase your risk of infections, including seasonal colds. A compromised immune system interferes with everyday living and well-being by causing infections and diseases.
Weaker bones
Vitamin D and calcium absorption are closely related; your body cannot adequately absorb calcium if you don’t have enough vitamin D.
Bone density continues to develop until approximately age 30, so a deficiency might result in decreased bone density.
The DHA recommends Vitamin D supplements Dubai for infants and young children since it is so important for healthy bone growth. A lack of vitamin D throughout childhood may increase the risk of osteoporosis and fractures later in life.
Poor mental health
Vitamin D is strongly associated with mental health, especially depression, according to growing research. Even if most studies call for further research, there is no denying that spending time in nature or the fresh air has a positive impact on mood.
What Can Young People Do To Improve Their Vitamin D Levels?
Vitamin D is good for everyone. Here are four easy methods that anybody may use to raise their vitamin D levels.
1. Spend more time outdoors
Some of the UVB rays might still reach you on a cloudy day. To increase your vitamin D levels, spend only fifteen minutes in the sun without using sunscreen. If you spend more time outside, wear sunscreen to lower your chance of developing skin cancer. Here are some suggestions for outdoor activities:
- Go for a quick early morning or evening walk.
- Walk the remaining distance after getting off your metro or bus one stop early.
- Engage in outdoor sports like cricket, padel, and swimming.
- Rather than sitting at your desk, take a coffee break outside.
The most crucial thing is to expose your forearms and legs where possible for better absorption.
For optimal UVB absorption, try to go outside in the early morning or late afternoon, but once you’ve soaked up the sun’s rays, don’t forget to apply sunscreen!
2. Eat more vitamin D-rich foods
Among the inexpensive, vitamin D-rich foods are:
- Tuna with wholemeal bread, a natural source of vitamin D and protein
- Scrambled eggs with mushrooms
- When making toast with canned sardines, use wholemeal bread instead of white bread because it is higher in nutrients (some wholemeal breads are even fortified with vitamin D).
3. Take a supplement
During the cooler months, health authorities advise everyone to take a daily vitamin D supplement. It is better to use vitamin D3 pills rather than vitamin D2 or D.
4. Raise awareness and educate
We may raise awareness and encourage proactive healthcare by actively participating in our own health or encouraging others to prioritize their health.
- Teaching your children how to prepare nutritious meals is a lifelong lesson.
- By spending more time outside, you may develop positive habits and encourage others to follow suit.
- You may share this information, take them for walks in the sun, or suggest that they check their vitamin D levels if you know someone who may be at risk of becoming deficient.
- Routine health screenings, including a vitamin D blood test Dubai, can help detect deficiency early, especially in young adults showing no obvious symptoms.
