Vitamin D deficiency affects individuals of all ages worldwide. Modern lifestyles, limited sun exposure, and poor diets are the primary factors contributing to this deficiency.
A common question that you might ask is: how can you prevent vitamin D deficiency and restore healthy levels?
The answer is simple: regular sun exposure and adding vitamin D-rich foods to your diet. However, if you want to increase vitamin D levels quickly and maintain them consistently, vitamin D supplementation may also be necessary.
Choosing the best vitamin D supplement in Pakistan can be challenging, as there are several options available on the market. Look for three important aspects:
-
Type of vitamin D – choose D3 for better absorption
-
Dosage – check if International Units (IU) match your needs
-
Certifications – select trusted brands with USP and DRAP approvals
For those looking to meet these criteria, Activit aligns with them by providing vitamin D3 (Cholecalciferol) in an optimal dosage to support your health.
Now let’s take a closer look at how vitamin D supports your overall health!
Understanding Vitamin D
Vitamin D is a fat-soluble vitamin that enhances the absorption of calcium, magnesium, and phosphorus while also performing several other important bodily functions. In humans, there are two forms of vitamin D2 and D3.
Vitamin D2 vs D3: Which is Better for Your Health
Vitamin D2 is plant-based and derived from fungi or yeast, while vitamin D3 is animal-based and obtained from fish liver oil or lanolin (from sheep’s wool).
When it comes to vitamin D supplementation, D3 (cholecalciferol) is generally considered more potent than D2 (ergocalciferol). As vitamin D3 is a form that your body naturally produces, it is more bioavailable and effectively absorbed and utilized in your body.
That is why most people prefer D3, particularly to support bone health and immune function. One such option is Activit, which contains vitamin D3 at an optimal dosage of 5000 IU for enhanced benefits.
What is Vitamin D Deficiency
Vitamin D deficiency or hypovitaminosis D is a condition in which you have vitamin D levels below normal. This condition occurs in individuals who have inadequate sunlight exposure, particularly in areas with insufficient ultraviolet B (UVB) rays.
Generally, the 25-hydroxy vitamin D test is used to measure vitamin D levels in the body. The normal and abnormal range of vitamin D levels are:
-
Normal range – 20 to 50 ng/mL.
-
Insufficient rage – 12 to 20 ng/mL.
-
Deficiency range – Below 12 ng/mL.
-
Higher range – above 50 ng/mL indicates toxicity.
What Are the Symptoms of Vitamin D Deficiency
Commonly, there are no prominent symptoms of low vitamin D levels in adults, which is why the deficiency can go unnoticed for long periods. However, other symptoms that can be signs of vitamin D deficiency include:
-
Muscle, joint, or bone pain
-
Bone loss and joint deformities
-
Muscle tremors or twitches
-
Muscle spasms
-
Bowed legs in case of severe deficiency
-
Muscle weakness, aches, and cramps
-
Mood changes, depression, or sleep disorders
-
A tingly sensation in the hands or feet
How to Prevent Vitamin D Deficiency Naturally
To prevent vitamin D deficiency naturally, consider increasing your levels through a vitamin D-rich diet and regular sunlight exposure – your two most reliable natural sources.
Vitamin D Foods
Fatty fish (tuna, mackerel, sardines, trout, and salmon), beef liver, egg yolks, certain types of mushrooms, fortified cereals, and milk are excellent sources of vitamin D.
Consuming these foods regularly may help increase vitamin D levels in your body.
Sunlight Exposure
Sunlight is the primary source that triggers the skin to produce vitamin D in the body. Exposure to the sun for 15 to 20 minutes is sufficient.
The best times to get vitamin D from sunlight are in the morning or early afternoon. During these times, the sun's UVB rays are most intense, which is when your skin is most efficient at making vitamin D.
However, prolonged exposure, especially during peak sun hours from 10 am to 4 pm, can lead to skin damage. It's important to balance your sunlight exposure to maximize vitamin D production while minimizing the risk of sunburn and skin cancer. Additionally, elderly individuals or those with darker skin may require more sunlight exposure to produce the same amount of vitamin D.
Preventing Vitamin D Deficiency With Supplementation
Consider taking vitamin D supplementation, especially during the winter months when there is limited sunlight and reduced sun exposure. Vitamin D supplements with 400 to 100 International Units (IU) of vitamin D3 may be sufficient for many adults. Activit provides 5,000 IU of vitamin D3, delivering a higher dose for those who need additional support in maintaining optimal vitamin D levels. However, the dosage may vary depending on an individual's needs and health conditions. To choose a vitamin D supplement, it is imperative to consult a healthcare professional.
Note that regular blood monitoring is crucial to ensure you are getting enough vitamin D.
The Role of Vitamin D in the Body
Supports Bone Health
Bones are primarily composed of calcium, which supports bone strength and density. Phosphorus – another essential building block of bones – is crucial for maintaining bone structure.
But where does the Vitamin D come into play?
Vitamin D is essential for bone strength as it promotes calcium absorption. It helps your body maintain an adequate amount of calcium and phosphorus in your blood, which are essential for enhancing bone density and maintaining the strength of bones and teeth.
Vitamin D deficiency can lead to serious bone-related issues in both children and adults. In children, it may cause rickets, a condition that results in soft and weak bones. In adults, it can lead to osteomalacia and osteoporosis, which reduce bone density, soften the bones, and increase the risk of deformities and fractures.
Promotes Immune Function
Vitamin D regulates your body’s natural defense system by promoting the immune response. How?
It helps produce a hormone called calcitriol, which is the active form of vitamin D. Once formed, calcitriol binds to vitamin D receptors on immune cells, including T cells, B cells, and macrophages. This interaction stimulates and supports the immune function, helping the body fight against pathogens and reducing inflammation.
For this reason, many researchers believe there is a strong connection between vitamin D deficiency and autoimmune conditions. Studies suggest that vitamin D helps regulate immune responses and may reduce the risk of several autoimmune diseases, such as type 1 diabetes and rheumatoid arthritis. However, the research shows mixed results, and further studies are needed to fully understand the relationship.
Regulates Mood
Vitamin D plays a crucial role in regulating mood and sleep. It achieves this by regulating the production of mood and sleep-related neurotransmitters, such as serotonin, dopamine, and melatonin. A deficiency in vitamin D can disrupt these processes, leading to mood changes, depression, and sleep disorders.
Here’s how: Vitamin D regulates the mood and sleep-related neurotransmitters, such as serotonin, dopamine, and melatonin. A vitamin D deficiency may disrupt these regulating processes, leading to mood changes, depression, and sleep disorders.
Due to these potential benefits, the best multivitamins in Pakistan, like Activit, include vitamin D in their formulations. Activit contains vitamin D3 (cholecalciferol) instead of vitamin D2 in its formula, as vitamin D3 is the natural form of vitamin D.
Why Is Vitamin D Deficiency on the Rise?
Urban Lifestyle and Less Sun Exposure
In urban populations, particularly in South Asian regions, vitamin D deficiency is highly prevalent. In Pakistan, the prevalence rate was found to be as high as 73% among adults.
But the question remains: why is vitamin D deficiency so prevalent in urban populations?
The answer lies in several factors. Urban residents often lead busy lifestyles and spend more time indoors, whether at work, at home, or in their vehicles.
With limited outdoor activities and longer working hours, urban dwellers often have less time to get sunlight, which can lead to vitamin D deficiency.
Sunscreen Use and Vitamin D Blockage
While sunscreen is crucial for protecting the skin from UV rays, it blocks the UVB rays required for vitamin D production. Sunscreens with SPF above 30 can block 95% of UVB rays, significantly reducing the skin’s ability to produce vitamin D. Consequently, people who use sunscreen regularly, especially in high quantities, may face a challenge in maintaining healthy vitamin D levels, despite their protection from skin damage.
Air Pollution Reduces UVB Rays
Air pollution can also be a factor contributing to vitamin D deficiency. How? Air-polluting elements, such as smog and particulate matter, absorb and scatter UVB rays, preventing them from reaching the Earth’s surface.
Consequently, individuals residing in polluted areas may face a deficiency, as reduced UVB exposure hinders the body from producing sufficient amounts of vitamin D.
Dietary Gaps and Vitamin D Deficiency
When it comes to providing the nutrients essential for achieving healthy vitamin D levels, modern diets often fall short. A diet high in processed and fast food, which is common due to busy lifestyles, typically fails to provide sufficient levels of vitamins, resulting in vitamin D deficiency.
Generally, animal-based foods are richer in vitamin D than plant-based foods. Therefore, vegans and vegetarians have a higher risk of experiencing vitamin D deficiency. In this situation, vitamin D supplementation becomes indispensable. Activit, the best multivitamin in Pakistan, provides vitamin D in a bioavailable form, which is suitable for individuals with dietary restrictions.
Impact of Obesity on Vitamin D Absorption
The rising obesity rates are also linked to lower vitamin D levels in the body. Why?
It is a well-known fact that vitamin D is a fat-soluble vitamin, which means it tends to be stored in fat cells rather than circulating in the blood, resulting in less vitamin D available to the body. As a result, obese individuals may experience lower bioavailability of vitamin D, making it more challenging for their bodies to utilize the vitamin effectively. This also means that individuals with higher body fat may need a higher vitamin D dosage to achieve optimal levels compared to those with a lower body fat percentage.
Who is Most At Risk
-
Older adults
-
Individuals with dietary restrictions (vegans and vegetarians)
-
Individuals with darker skin
-
Breastfeeding mothers
-
Individuals with chronic illnesses (like inflammatory bowel disease or celiac disease)
The Bottom Line
Vitamin D offers several potential benefits – improving bone and muscle health, enhancing immune function, managing a healthy weight, and regulating moods and sleep.
However, due to poor dietary choices and busy lifestyles, it can be challenging to get enough vitamin D from sunlight and food alone. Therefore, after assessing your health needs, it is advisable to consult your healthcare provider and consider taking a vitamin D supplement regularly.
