Although it’s the time of year when people outside begin to layer up, feeling cold all the time could be a sign of something else, specifically, nutrient deficiencies in the body.
A lack of the essential vitamins and minerals the body needs can lead to a host of issues that could permanently affect your health.
Discovering the symptoms to watch out for and knowing the vitamins you may be lacking are crucial for your continued well-being.
Understanding Nutrient Deficiencies
When we lack essential vitamins and minerals, our bodies may not function as they should. Vitamin B12, iron, and iodine are common vitamins and minerals often lacking.
By prioritizing proper nutrition and consuming a balanced diet, we can help prevent these deficiencies.
Whether you’re vegan, pregnant, or following a plant-based diet, it’s important to ensure adequate intake of nutrients like iron, calcium, vitamin D, and vitamin A. These micronutrients are vital for bone health, red blood cell production, and immune function.
You can proactively safeguard your health by being aware of your nutrient intake and potential deficiencies.
Common Symptoms of Nutrient Deficiencies
Generally speaking, the following signs are all indications of a diet that is lacking the required vitamins and minerals:
- Mouth ulcers
- Cracks in the corners of your mouth
- Hair loss
- Excess dandruff
- Scaly patches on your skin
- Red or white bumps on your body
- Diminished vision at night
The symptoms listed above are just some of the ways our bodies let us know something isn’t right. Nutrient deficiencies can impact the immune system, leading to frequent infections and delayed wound healing. It’s wise to pay attention whenever something seems out of the ordinary.
Feeling Cold All the Time
Feeling constantly cold may indicate nutrient deficiencies that affect temperature regulation and blood circulation. Inadequate intake of vitamins and minerals and thyroid hormone imbalances can contribute to cold intolerance.
A change in diet and dietary supplements can help prevent and combat nutritional deficiencies. However, it’s always good to consult a healthcare professional to identify what’s happening with your body and receive guidance on addressing any abnormalities.
Fatigue and Lack of Energy
Specific vitamins and minerals, such as vitamin C, B12, iron, and magnesium, are essential for energy production. They allow the body to convert food into usable energy.
There may be a good reason for the constant energy drain and sluggishness you’ve been experiencing.
Brittle Nails and Hair
Physical appearances are often a good indication of someone’s health.
Some people blame feeling cold all the time on the change in weather; people with dry, frizzy hair and brittle nails use the same excuse. However, this uncomfortable state is usually due to a lack of B7 being absorbed into your body and circulating through the bloodstream.
Role of Key Vitamins and Minerals in Body Temperature Regulation
Vitamin B12 and Iron: Crucial for Red Blood Cell Production
Vitamin B12 and iron are essential for healthy red blood cell production. Deficiencies in these nutrients can cause anemia, leading to decreased red blood cell count and feeling cold. To maintain optimal blood cell function, a diet rich in B12 is recommended and may include shellfish, clams, oysters, liver, meat, eggs, and milk products.
Iron, which is essential for producing the hemoglobin that transfers oxygen from your lungs to other body tissues, is found in meat, poultry, fish, eggs, beans, peas, spinach, whole grains, and nuts.
Again, a good multivitamin, like the Vitamin100 Multivitamin by Vitamin Armor, can help supplement people’s nutritional needs. Not everyone is going to eat everything they need all the time.
Addressing nutrient deficiencies improves red blood cell production and regulates body temperature effectively.
Iodine and Thyroid Function: Regulating Metabolism and Body Temperature
Iodine is essential for thyroid function and body temperature regulation. Iodine deficiencies can disrupt thyroid function and affect temperature regulation.
If you suspect an iodine deficiency, consult a healthcare professional for assessment and guidance on addressing deficiencies.
Can Vitamin100 by Vitamin Armor Help?
If you’re suddenly feeling cold all the time, sluggish, or you’ve noticed you’re not looking like your usual self, it could be a sign of a nutrient deficiency.
Although age and lifestyle will always be a factor, readjusting your diet or adding a vitamin supplement may be exactly what you need. It’s all about having the correct dosage for your body.
Vitamin Armor 100 is a high-quality supplement formulated to counteract the effects of vitamin and mineral deficiencies. If you have any questions about this product, don’t hesitate to reach out.
Vitamin100: Fueling Athletes with 100% Essential Nutrition
Understanding Vitamins: Your Guide to Daily Essentials
From D to Victory: The Impact of Vitamin D on Athletic Success
Vitamin D is associated with healthy bones (calcium homeostasis and bone metabolism) and good overall health. It is one of many benefits of getting outside on a sunny day.
Unfortunately, for a significant portion of the population (and many athletes), meeting their suggested daily intake is not as simple as spending time outdoors.
As Vitamin D deficiency becomes a more prevalent problem globally, more research has focused on how it affects athletes. Most reports describe a strong connection between vitamin D and overall health and, in some instances, how it can improve athletic performance.
The Benefits for Athletes
Although it would be too grand a generalization to say that adequate vitamin D always enhances athletic outcomes, there is strong evidence supporting its importance for long-term health. Ensuring proper vitamin D levels benefits athletes of every sport.
Notable Physical Improvements
Several studies have shown the efficacy of supplements in improving athletic performance across different sports. In most of these experiments, two groups of test subjects were observed: one group that received vitamin D supplements and another that consumed placebos.
One study that focused on elite dancers noted a significant difference in vertical jump heights and an increase in isometric strength, with the results favoring those who took the supplement.
In a similar study involving weights, there was a “trend toward significant improvement” as a group of soccer players who took the supplement rated higher during bench lifting and back squats.
Other studies focusing on aerobic capacity observed positive results concerning the test subjects’ oxygen uptake and workout capacity.
The Trouble with Vitamin D Deficiencies
According to the National Institute of Health’s National Library of Medicine website, approximately 35% of American adults lack sufficient quantities of vitamin D. There are several potential health issues associated with vitamin D deficiencies.
It’s not always easy to tell if you are vitamin D deficient. However, achiness, muscle weakness, depression, and trouble sleeping are just some of the common symptoms.
Getting the Correct Amount
Measuring your vitamin D level is straightforward with a 25(OH)D blood test.
Supplements offer an effective way to compensate for any vitamin D deficiency detected, as vitamin D is difficult to obtain through diet alone. Eating foods such as sardines (fatty fish), mushrooms, eggs, egg yolks, red meat, and certain cereals can help.
There is no consensus on how much vitamin D an athlete needs—factors such as age, race, location, and the season will factor into the determination.
Vitamin D supplements are available in vitamin D2 and vitamin D3 formulations, with vitamin D3 being the more active of the two. You’ll find brands containing between 400 and 50,000 IUs (International Units). It’s important not to overcompensate by taking too much.
When in doubt, a discussion with your doctor or the advice of a reputable supplement company should be able to answer all your questions.
Vitamin Armor Is Specially Formulated for Active Lifestyles
Although there is no set prescribed amount of vitamin D for adult athletes, it appears that athletes require more than the general populace.
As a dedicated athlete, you never want to shortchange your performance or jeopardize your well-being. Doctor-formulated Vitamin Armor fills in the nutritional gaps so you can concentrate on being your best.

How Does a Vitamin D Deficiency Affect Athletes?
Vitamin D, or “the sunshine vitamin,” is crucial for one’s overall health. It supports bone strength and muscle function and reduces inflammation. Optimal levels may also lower the risk of chronic diseases like cancer and heart disease.
Sunlight exposure helps produce vitamin D, but its production is affected by various factors.
Athletes should recognize the importance of vitamin D in their physical performance, recovery times, and overall well-being.
Optimal Vitamin D Levels for Athletes
According to an article from the National Library of Medicine from 2020, vitamin D deficiencies in the general population are a growing concern. According to several reported studies, “a high prevalence of vitamin D deficiency has been documented in athletes in both outdoor and indoor sports.”
A blood level of 30 ng/mL or higher is recommended for athletes, and regular tests can help monitor and adjust vitamin D levels as needed.
Vitamin D plays a crucial role in the following areas:
Insufficient vitamin D can weaken muscle strength, power, and endurance by affecting phosphorus absorption. A vitamin D deficiency could also lead to muscle injuries and inflammation following exercise.
Identifying the Signs of Vitamin D Deficiency in Athletes
If you’re feeling held back in your athletic performance, symptoms to watch out for include:
Regular testing and monitoring of vitamin D levels are essential for optimal health, especially for power athletes hoping to boost their performance.
Causes of Vitamin D Deficiency in Athletes
Athletes can develop a vitamin D deficiency due to limited sun exposure, dietary factors (lactose intolerance and vegan diets), darker skin pigmentation, and certain health conditions (inflammatory bowel disease, Crohn’s disease, Celiac disease).
Factors like indoor training, air pollution, cold weather, and sunscreen can limit a person’s sun exposure, lowering vitamin D production in the skin.
Testing and Diagnosis of Vitamin D Deficiency in Athletes
If any of the listed information applies to you, testing for vitamin D levels is recommended. Methods involve measuring 25-hydroxyvitamin D concentration in the blood. Levels below 20 ng/mL indicate a deficiency.
Any sudden change in your health should involve a consultation with a doctor. However, there are several vitamin D deficiency tests for purchase that you can perform at home.
With accurate interpretation, athletes can take proactive steps to improve their vitamin D status.
Managing and Treating Vitamin D Deficiency in Athletes
Athletes with low vitamin D levels can benefit from targeted intervention. Treatment may involve high-dose supplementation under medical supervision, safe sun exposure, and dietary modifications.
Ten to 30 minutes of sunlight multiple times per week is generally recommended for most people.
Supplements also play a crucial role in helping athletes achieve optimal vitamin D levels.
Consulting a healthcare professional for guidance on supplementation is essential to avoid taking too much in order to compensate.
Dietary Changes to Increase Vitamin D Intake
Athletes can prioritize vitamin D-rich foods, including salmon and sardines, egg yolks, red meat, certain breakfast cereals, and fortified dairy products to maintain optimal levels.
By incorporating vitamin D supplements into their regimen, athletes can ensure their bodies receive the necessary support for their day-to-day health, training, and performance.
How Does a Vitamin D Supplement Like Vitamin Armor Help?
Vitamin Armor is a reliable supplement that helps athletes maintain optimal vitamin D levels for efficient absorption and utilization in the body. With a doctor-formulated daily dose of 5,000 IU, one capsule daily is all you need. Proper dosing is essential to avoid any potential adverse side effects.

The Best Time to Take Nutritional Supplements
Nutritional supplements can enhance a healthy lifestyle by providing the essential nutrients your body needs. However, the time of day (and how you consume it) can affect its overall performance.
Let’s dive into the general recommendations.
Nutritional Supplements with Meals vs. Without Meals
Many people start their day with a vitamin supplement as part of their breakfast routine. However, just as many opt to take it with a large meal in the evening. It begs the question, are there any vitamin supplements that don’t require food?
The quick answer is that there is no single correct response that applies to every vitamin and mineral. It all boils down to a few different factors.
The Advantages of Taking Supplements at Night
Taking supplements at night can offer unique advantages, especially for supporting the body’s natural sleep processes. Vitamin E, for example, has been known to help people who have trouble sleeping.
Here are a few benefits of nighttime supplement intake:
Keep in mind that supplement dosages may vary, so it’s important to consider the specific ingredients and their potential effects before incorporating them into your nighttime routine.
Benefits of Consuming Supplements During the Day
On the other hand, there are multiple advantages to consuming supplements during the day. Supplements in the morning or afternoon can benefit those with an active lifestyle.
Recommendations for Nutritional Supplements
Here are a few recommendations when adding a supplement as part of your health and wellness routine:
Make Things Easy with Supplements by Vitamin Armor
Remember, nutritional supplements should complement a healthy diet, not replace it.
Suppose you take a multivitamin, like the specially formulated Vitamin 100 Multivitamin by Vitamin Armor. In that case, it is generally recommended that you eat it with a meal when you start your day.
Vitamin Armor’s D3 supplement should also be taken with a meal, but it can be ingested at any time of day.
If you have any questions related to vitamin usage, Vitamin Armor is happy to answer them.
Do Vitamins Help with Sports Performance?
A balanced diet is crucial for athletes’ training and performance. It ensures you have the necessary fuel for maximum output. Proper nutrition also reduces your risk of injury. By consuming the essential vitamins and nutrients, athletes can build up their stamina for use when it really counts.
The Importance of a Balanced Diet
Whether you’re a middle-aged man playing sports for recreation or a young woman training for the Olympics, adequate nutrition is essential for supporting your training and protecting your body from harm.
In the same way your body craves water during a workout, your body demands a certain amount of vitamins and minerals for optimum efficiency. Physical activity and a suitable diet are your best defense against any number of health concerns, including:
Vitamins are essential for supporting the body’s biological processes. Unfortunately, people cannot produce all the micronutrients necessary for optimum health. Ensuring you get the correct daily amount is essential for everyone, not just athletes.
The Role of Specific Vitamins in Energy Production and Muscle Function
Let’s explore some of the most notable vitamins for athletic lifestyles. All of these vitamins support your overall wellness and bolster athletic endurance.
Vitamin D and Bone Health
Vitamin D is important for athletes, especially in maintaining muscle and bone health. It contributes to better performance, posture, agility, and strength. It is also known to help prevent muscle spasms.
Maintaining the optimum amount of vitamin D is not a problem for most people as it is stored in the liver and gradually released. Many multivitamin products don’t include it. However, if you don’t get enough natural sunlight, have darker skin, or your diet excludes oily fish, egg yolks, cheese, or red meat, you may not be getting the recommended amount. This makes a product like the Vitamin Armor D3 Supplement crucial, especially during the winter when you’re covering up outside and spending most of your time indoors.
B Vitamins and Energy Metabolism
B vitamins (B1, B2, B3, B5, B6, B7, B9, and B12) are essential for athletes’ energy metabolism, endurance, agility, physical therapy, performance goals, lower body agility, acceleration, range of motion, upper body strength, coordination, and posture.
Vitamin C for Immune Function and Collagen Synthesis
Vitamin C is essential for athletes as it boosts their immune system and improves various aspects of their performance, including endurance, strength, coordination, and injury prevention.
Vitamin E as an Antioxidant
Adequate vitamin E intake is integral for upper body strength, range of motion, and better acceleration and change of direction. Antioxidants significantly impact athletic training by counteracting oxidative stress.
How Multivitamins Boost Sports Performance
Filling nutritional gaps with multivitamins is essential for athletes looking to take their game to the next level. Multivitamins offer several benefits, particularly for active adults without a dietician or personal trainer to enforce a strict diet.
What can a good multivitamin do for you?
Considerations for Choosing Vitamin Supplements
When selecting vitamin supplements to improve sports performance, athletes should prioritize purity and quality, opting for those free of artificial additives. The form of the vitamin, safety testing, and consultation with a sports nutritionist are crucial considerations.
Mega-dosing of vitamins over prolonged periods can lead to profound health implications with fatal results.
Vitamin Armor vitamin supplements are formulated in compliance with the standards and daily recommended allowances set forth by The Office of Dietary Supplements (ODS), which is part of the National Institutes of Health (NIH).
As an athlete, you want to maximize your potential, whether you’re on the field, on the court, or in the gym. Vitamin Armor vitamins protect your body for optimum sports performance.

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.
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:
Our bodies cannot produce vitamin B12 on their own, so you need to consume foods rich in vitamin B12 such as:
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.
When vitamin B12 is too low (below 200), it can cause several health complications such as:
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:
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:
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.
Purchase High-Quality Vitamin B12 from Vitamin Armor
To ensure that your body is absorbing the correct amount of vitamin B12, you should consult your doctor so that they can prescribe the right dose depending on the category you fall into.
This enhances your recovery rate since consuming high-quality, carefully formulated vitamin B12 supplements ensures that you receive the maximum benefits of this essential nutrient.
Get 100% of your daily essential vitamins and minerals and take a step closer to a healthier you with Vitamin Armor’s vitamins and supplements.
