Vitamin D Supplementation

Does Vitamin D Supplementation Reduce Mortality?

Scientists are constantly searching for the fountain of life. They try to understand what makes us keep ticking – is it what we eat, how much we exercise, what is that X-factor that will keep us healthier, and alive, for longer? So far there has been no single answer to what can increase our lifespans. It’s always been a combination of genetics, lifestyle, eating and exercise habits that are credited with living longer and more fulfilling lives. 

This question has led to some intensive, and interesting, research on the function of Vitamin D and the role it plays in reducing mortality. One paper published in 2007 analyzed 18 independent randomized controlled trials, including 57,311 participants while another studied results of randomized controlled trials that were published between 1983 and 2022. Both explored the effects of Vitamin D on mortality with interesting results. 

While there have been plenty of other such reviews, these two papers demonstrate well-conducted systematic reviews and meta-analyses with reliable results. 

Why Vitamin D Supplementation?

Vitamin D plays an important role in our body’s functions covering a wide spectrum of its activities – from building immunity to healthy hearts. It shot back into the spotlight during the dark days of the pandemic when researchers found a link between patients from countries with high COVID-19 mortality and lower levels of Vitamin D. They found that Vitamin D enhanced our immune systems and prevented them from becoming dangerously overactive which in turn could protect patients against severe complications, including death, from COVID-19. 

The effects of Vitamin D in boosting immunity against COVID are now well-known. However, science has also found some other interesting benefits of Vitamin D and its effects on our lives.

  • Vitamin D and Cancer: One study found that although Vitamin D supplementation did not reduce the incidence of cancer, it significantly reduced total cancer mortality. Another study conducted in Germany recommended that anyone aged 50 or older may benefit from Vitamin D supplementation as regular doses of Vitamin D3 can reduce cancer mortality rates by 12%. However, the mechanism behind these findings requires more research. 
  • Vitamin D and Your Heart: The relationship between Vitamin D and cardiovascular function is much more complex and scientists are still trying to understand it. One review found that a Vitamin D deficiency is linked to major adverse cardiovascular events (MACE). However, whether Vitamin D supplementation can be preventive in nature is still a question and requires additional research. 
  • Vitamin D and Diabetes: The American Diabetes Association reports that low Vitamin D levels have also been linked to how your body uses insulin. It reports that the chances of developing insulin resistance are lower with Vitamin D supplementation. For those suffering from diabetes, they recommend getting Vitamin D levels tested as low Vitamin D levels have been linked to the development of foot ulcers.

Summing Up the Research

The effect of vitamin D on mortality is a topic of ongoing research and debate. Observational studies suggest that there is a strong possibility of a link between low Vitamin D levels and conditions like cancer, heart disease, and immune deficiencies. However, we still don’t know how genetics, race, lifestyle, and other factors determine the effects Vitamin D supplementation has on mortality. Having said that, the initial results are intriguing and demonstrate the importance of maintaining your Vitamin D levels. 

So, while the jury’s still out on whether Vitamin D reduces mortality and although we don’t know if Vitamin D has a positive effect on mortality overall, it can certainly help you live a healthier and happier life

A Word of Caution:

It’s always a good idea to get your Vitamin D levels tested as taking too much vitamin D can be harmful leading to a buildup of calcium in your blood (hypercalcemia), which can cause nausea and vomiting, weakness, and frequent urination. 

While supplements can be beneficial to your daily routine, they should complement a balanced diet, not replace one. Always consult with a healthcare professional before starting any supplement regimen, as individual nutrient needs may vary based on age, health status, and lifestyle. Contact Dr. Datz if you need help choosing the right vitamins for you.

How Long Does It Take to Recover From Vitamin B12 Deficiency?

Recovery from a vitamin B12 deficiency varies. It depends on the causes, symptoms and treatment plans.

Mild and borderline cases can take a few days to weeks after starting B12 supplementation or treatment.

However, complete recovery in some cases of vitamin B12 deficiency with neurological symptoms may take months.

To understand how long it takes to recover from Vitamin B12 deficiency, you must first learn what it is and what factors influence it.

Understanding Vitamin B12 Deficiency

Vitamin B12 is a water-soluble vitamin that aids in:

  1. Protecting the nerves from damage.
  2. Absorption and breaking down of carbohydrates, fats and proteins to use them as energy.
  3. Creating new cells (DNA synthesis).
  4. Generation of red blood cells, which deliver oxygen to organs.

Our bodies cannot produce vitamin B12 on their own, so you need to consume foods rich in vitamin B12 such as:

  • Organ meats like lamb liver and kidneys
  • Red meat
  • Poultry
  • Eggs
  • Milk ( Whole, soy, almond or rice), cheese and Yogurt
  • Sardines
  • Clams

Failure to take vitamin B12-rich foods results in three types of deficiency.

The table below shows these three types of B12 insufficiency and what this could mean for you.

B12 Level (pg/mL) Interpretation Explanation
Above 300 Normal B12 levels are within the healthy range
200 – 300 Borderline B12 levels are slightly below normal. Can signal early stages of deficiency or variations in absorption but you need further investigation by a doctor
Below 200 Deficient B12 levels are significantly below the recommended range, indicating a clear deficiency. At this level, you need immediate medical attention

When vitamin B12 is too low (below 200), it can cause several  health complications such as: 

  1. Headaches
  2. Anemia 
  3. Fatigue
  4. Depression
  5. Difficulty concentrating and cognitive impairments
  6. Gastrointestinal issues like diarrhea, nausea, constipation, bloating and gas

Factors Affecting Vitamin B12 Deficiency Recovery

Various factors affect how you recover from vitamin B12 deficiency. 

These include:

A. Age and Lifestyle

Our bodies have the capabilities to absorb the essential minerals and nutrients, from what we consume.

Therefore, the food we eat determines whether we contribute to excess, normal, or inadequate production of these nutrients.

And vitamin B12—a vital nutrient—is affected by our eating patterns.

However, as we age our ability to absorb vitamin B12 diminishes, leading to a deficiency.

Besides our age, our lifestyle and dietary preferences play a role in determining our vitamin B12 intake.

And since most vitamin B12 from food comes from animal sources, the likelihood of deficiency increases if you adhere to a strict vegetarian or vegan diet. 

You can still follow your preferred eating plan as long as you include more plant-based foods high in vitamin B12 in your diet. These include:

  • Almond milk
  • Soy milk
  • Rice milk
  • Oats
  • Bran
  • Corn

If you don’t follow a strict diet plan, it’s still important to include foods high in vitamin B12 in your daily meals.

B. Underlying Conditions

If you have any underlying medical concerns your recovery time for vitamin B12 insufficiency may be impacted.

For example, digestive illnesses such as Crohn’s disease and Celiac disease might impair vitamin B12 absorption. This is because an inflamed or damaged stomach lining prevents vitamin B12 absorption.

Some acid reflux and heartburn medications like proton pump inhibitors (PPIs) may affect the absorption of vitamin B12. PPIs have the potential to harm the stomach cells that generate intrinsic factor—a protein necessary for the absorption of vitamin B12—leading to a deficiency.

As a result, using vitamin B12 injections for life may be necessary in some cases.

Adherence to Treatment

Once a healthcare professional determines your level of vitamin B12 deficiency, they recommend the appropriate treatment plan for your specific situation.

These might include:

  • Taking supplements
  • Eating more foods that are high in vitamin B12
  • Receiving larger doses of B12 through injections

However, deviating from the suggested treatment course may make recovery time longer.

This is due to the fact that your body is still not getting the 2.4 micrograms (mcg) of vitamin B12 that is needed daily for adults over the age of 14.

The Role of Essential Vitamins in Your Body

In the quest for optimal health and well-being, essential vitamins play a pivotal role in ensuring that our bodies function at their best. Essential vitamins are organic compounds that are necessary for normal growth, development, and overall well-being. Among these vital nutrients, vitamin D3 and daily multivitamins stand out as cornerstones in maintaining your overall health. 

Vitamin D3: The Sunshine Vitamin

Often referred to as the “sunshine vitamin,” vitamin D3 is unique among vitamins because our bodies can synthesize it when exposed to sunlight. Vitamin D3 is a critical nutrient in several crucial processes.

Bone health

Vitamin D3 is essential for absorbing calcium and phosphorus, vital minerals that support bone health and strength. A deficiency in vitamin D3 can lead to weakened bones, increasing the risk of osteoporosis and fractures. 

Immune System Support

Vitamin D3 plays a vital role in modulating the immune system, helping it respond effectively to infections, and preventing autoimmune reactions. 

Your mood and mental health

Some studies suggest that vitamin D3 may influence mood, and mental health, with potential links to conditions like depression and anxiety. 

A healthy heart

Adequate levels of vitamin D3 are associated with a reduced risk of cardiovascular diseases, as it helps regulate blood pressure and supports a healthy heart. 

Muscle function

Vitamin D3 is critical for muscle function, coordination, and strength. Deficiencies may lead to muscle weakness and an increased risk of falls, particularly among older adults.

Get your daily nutritional boost with a multivitamin

While a balanced diet is the best way to obtain essential vitamins, a daily multivitamin can act as an insurance policy to fill any potential nutritional gaps. 


A variety of nutrients

A good-quality multivitamin provides a broad spectrum of essential vitamins and minerals, ensuring you get various nutrients to support overall health. 

Increase your nutrient intake

Sometimes, you’re busy and just need to eat something fast. In today’s fast-paced world, sometimes our dietary choices are not the most nutritious. A daily multivitamin can provide that extra boost of essential vitamins your body needs to function optimally. 

Consistency is key

Taking a daily multivitamin is convenient and consistent to ensure you meet your daily nutrient requirements, especially if your diet is limited or lacks variety.

Nutrient support

Pregnant women, older adults, or people with specific dietary restrictions may have increased nutrient needs or difficulty obtaining certain vitamins from their diets. A tailored multivitamin can address these specific requirements. 

Nourishing necessities make your body thrive

Every vitamin plays a unique role in maintaining the health of various body systems. Deficiencies in essential vitamins can lead to various health issues and diseases. Maintaining a balanced and varied diet is essential to ensure an adequate intake of these essential nutrients. However, supplementation may be necessary in certain cases, such as when dietary intake is insufficient or when specific medical conditions impair absorption. Before starting any supplement regimen, it’s important to consult with a healthcare professional to ensure that it’s appropriate for individual needs.

Vitamins are crucial for maintaining optimal health and well-being. Vitamin D3 is a powerful nutrient that influences bone health, immune function, and much more. Daily multivitamins can provide a safety net to ensure you receive the full spectrum of essential vitamins and minerals. 

While supplements can be beneficial to your daily routine, they should complement a balanced diet, not replace one. Always consult with a healthcare professional before starting any supplement regimen, as individual nutrient needs may vary based on age, health status, and lifestyle. Contact Dr. Datz if you need help choosing the right vitamins for you.

5 Signs of Vitamin D Deficiency

Vitamin D deficiency can significantly impact our overall health and well-being. This essential nutrient is crucial in various bodily functions, including bone health, immune system regulation, and mood stabilization. However, certain signs and symptoms may emerge when our bodies lack sufficient vitamin D levels. Recognizing these five common signs of deficiency, such as fatigue, bone and joint pain, impaired wound healing, frequent illnesses, and mood changes, can be essential in identifying and addressing this nutritional deficiency to ensure optimal health and vitality.

What is vitamin D

Vitamin D is a fat-soluble vitamin that is naturally found in some foods and added to others. Vitamin D can also be produced in the body when the skin is exposed to sunlight. 

Vitamin D plays a vital role in regulating calcium and phosphate levels in the body, which are essential for maintaining healthy bones, teeth, and muscles. It aids in calcium absorption from the intestines, helps deposit calcium in bones, and prevents excessive loss through urine. Vitamin D has been linked to other health benefits, including immune function, cell growth and differentiation, mood regulation, and reducing the risk of certain diseases.


Vitamin D deficiency is a common health issue for many people

Because vitamin D is a unique nutrient, the body can synthesize it when the skin is exposed to sunlight, however, factors such as geographical location, time of year, sunscreen use, age, skin pigmentation, and time spent outdoors can affect the body’s ability to produce sufficient vitamin D. Therefore, dietary sources and supplements are often necessary to ensure adequate vitamin D levels, particularly in individuals who may have limited sun exposure or are at higher risk of deficiency.


Here are five common signs that may indicate a vitamin D deficiency:

  1. Fatigue and weakness: 

Feeling constantly tired, lacking energy, and experiencing muscle weakness can be signs of vitamin D deficiency.


  1. Bone and joint pain: 

Low vitamin D levels can lead to aches and pains in the bones and joints. This may include chronic back pain, joint stiffness, or general discomfort.


  1. Impaired wound healing: 

Vitamin D plays a crucial role in healing. If you notice that your wounds are slow or healing poorly, it could be a sign of vitamin D deficiency.


  1. Frequent illnesses or infections:

 Vitamin D is essential for maintaining a strong immune system. If you fall ill frequently, especially with respiratory infections like colds or flu, it could be a sign of vitamin D deficiency.


  1. Depression or mood changes: 

Research suggests a link between vitamin D deficiency and mood disorders such as depression and seasonal affective disorder (SAD). If you’re experiencing unexplained changes in mood or feelings of depression, it’s worth considering vitamin D levels.

Health and nutrition go hand in hand

Vitamin D deficiency can manifest in various ways, and the signs and symptoms can vary from person to person.  If you are experiencing health problems, it is important to see your doctor. Other conditions can also cause these symptoms, so it’s important to consult a healthcare professional for a proper diagnosis if you suspect a deficiency. A blood test can determine your vitamin D levels and guide appropriate treatment if necessary. A multivitamin is a great way to boost your vitamin intake if you are concerned about a deficiency. To learn more about how a multivitamin can help you, check out NIH’s collection of consumer fact sheets. It’s important to know your Vitamin D blood level since that will determine your dosing. You can contact Dr. Datz if you need help interpreting your Vitamin D level.
