What Vitamin Deficiency Causes You to Feel Cold? Symptoms to Identify
It is indeed an uncomfortable experience to feel cold all the time. Most people would relate this sensation to the weather but some could ascribe it to a number of reasons or, perhaps, other specific causes. One such common thing that people tend to ignore is the vitamin deficiency which actually makes a person feeling cold easily. Many types of vitamins and minerals perform functions that are vital for the regulation of body temperatures and blood circulation as well as the release of energy during metabolic processes inside the body. Therefore, when these nutrients become deficient in the body, heat generation and subsequently regulated temperature maintenance become impaired.
In this case, let's place some emphasis on how vitamin deficiency causes the feeling of being cold, along with some vitamins, including Vitamin B12, Vitamin D, Iron, Folate, and Magnesium, and also put up some symptoms to look for. A further explanation as to why that feeling of being cold is due to deficiency will be featured as well in addition to some of the remedies available for addressing deficiency symptoms.
How is Body Temperature Controlled?
The body has a thermoregulatory mechanism that keeps it at a fairly consistent temperature of about 98.6°F (37°C). It is necessary for enzyme activity, organ systems functioning, and metabolic processes in general. Thermoregulation operates in the following physiological mechanisms:
Blood Circulation: The blood vessels dilate and constrict to regulate heat flow. For example, when the body is too hot, the blood vessels expand or vasodilate to release heat; when it is too cold, the estate is then vasoconstricted to conserve heat.
Muscle Coiling: This is a condition when a body gets to a point of freezing temperatures. The muscles involuntarily contract to produce heat.
Sweating: The body heats up; perspiration evaporates from the skin, cooling the body down.
Thyroid: The hormones produced in the thyroid gland regulate metabolism and, as a side effect, heat production by the body.
Poor vitamin and mineral status can alter these reactions, making the environment feel cold when not so.
Vitamin B12 Deficiency and Cold Extremity Sensitivity
What is Vitamin B12?
Vitamin B12 (cobalamin) is a water-soluble vitamin and plays an important role in the functioning of the nerves and the production of red blood cells and DNA synthesis. It is mostly found in animal products such as meat, fish, dairy, and eggs. Vegetarians and vegans are at a greater risk of developing a deficiency of this vitamin because plant-based foods do not contain it.
Vitamin B12 Deficiency and Cold Feeling
1. Anemia and Peripheral Circulatory Problems: It is a very important vitamin in the making of red blood cells. Its lack will lead to pernicious anemia in the body, which can bring about a state in which there are too few red blood cells to carry oxygen effectively. Reduced circulation will then explain the “coldness” feeling, which is typically more widespread in the feet and hands.
2. Nerve Damage: Another place where vitamin B12 is significant would be that of existing healthy nerves. Then its deficiency may subsequently lead to damage of those nerves, and as a result, patients will complain of numbness, tingling sensations, and premature coldness of the extremities. Poorly functioning compromised nerves would make it difficult for the body to sense and regulate its temperature.
3. Slower Metabolism: B12 is quite important for energy metabolism. When B12 is not sufficiently supplied, the body's metabolism slows down, which means that not much heat is generated. The resultant feeling is one of being cold at times when the environment is warm.
Vitamin B12 Deficiency Symptoms
-Excessive tiredness
-Paler skin or skin with a yellowish tint.
-Numbness or tingling feeling in hands and feet.
-Breath shortness.
-Memory loss or a concentration issue (brain fog)
-Mouth sore or ulcers on the tongue.
-Walking or balancing is difficult.
Treatment for Vitamin B12 Deficiency
B12 supplements are the best treatment for the deficiency. These involve:
B12 Injections: Most likely, your doctor will suggest B12 injections if the deficiency is serious and needs to replenish the stores quickly.
Sublingual B12: If a person is not capable of absorbing enough B12 through the digestive channel, sublingual tablets or lozenges may prove effective.
Dietary Adjustments: Consumption of meat and fish; dairy products and eggs benefit from adequate B12 intake. But vegetarians and vegans should get fortified foods or supplements.

Vitamin D Deficiency and Cold Sensitivity
What is Vitamin D?
Vitamin D is a fat-soluble vitamin, and it is very necessary for bone health, immune system functioning, and regulation of calcium levels inside the body. It can be synthesized in the skin when exposed to the sunlight but available in fatty fishes, supplemented dairy, or even the egg yolks. People born in areas with low sunlight exposure especially during winter have a higher deficiency of vitamin D.
Cold Sensitivity Due to Vitamin D Deficiency
1. Immune System Dysfunction: An important contributor to immune system functions, vitamin D deficient persons have a poor immune system that develops chronic inflammation. Chronic inflammation affects the body's thermoregulation, resulting in increased sensitivity to cold.
2. Vasodilation : Vitamin D is also known to affect blood vessels. Thus, its deficiency would probably affect vasodilation and vasoconstriction; this would result to poor blood circulation, leaving the fingers and toes cold.
3. Lesser Thermogenesis: The body's process of generating body heat to maintain body temperature is thermogenesis. Vitamin D plays a role in the most important processes that allow activation of brown fat tissue, which is necessary for thermogenesis. Hence, lower levels of vitamin D may reduce the capacity of the body to produce and therefore cause it to be very cold.
Signs of Vitamin D Insufficiency
-Hoof hurts or muscles aching
-Endless fatigue irrespective of sleeping hour
-Tendency of getting sick repeatedly
-Changes in mood or depressed (Seasonal Affective Disorder, or SAD)
-Hair loss
-Difficulty sleeping
Sunlight Therapy to Cure Vitamin D Deficiency
Increase in Duration of Sunlight Outdoors: Exposure to the sun, particularly during mid-day hours, helps boost the production of vitamin D against deficiency.
Vitamin D Supplements: Deficiency is generally corrected by using D2 or D3 vitamin supplements. D3 is being favored among the two because it increases blood concentration more efficiently compared to D2.
Dietary Sources: Eating vitamin D foods like oily fishes (salmon, mackerel), fortified dairy products, and egg yolks also help in enhancing the intake.
Iron Deficiency and Cold Sensitivity
What is Iron?
Iron is one of the important minerals required for the production of hemoglobin, which is nothing but the protein found in red blood cells that mainly transport the oxygen throughout the body. This mineral has a very important role in energy metabolism as well as immune function. There is animal-based food (heme iron) and plant-based food (non-heme iron) which consists of iron; however, the absorption of heme iron is a lot more efficient than non-heme iron.
How Iron Deficiency Leads to Feeling Cold
1. Decreased Oxygen Transport: Lack of iron results in a dearth of production of hemoglobin and hence results in iron-deficiency anemia. Unfortunately, as there are fewer red blood cells for the transport of oxygen, the tissues and the organs may not receive adequate oxygenation leading to symptoms like fatigue, weakness, and cold extremities.
2. Increased Circulation: Very low iron levels can restrict blood flow more and in effect give poor heat distribution in the body. It is for this reason why people complain of cold hands and feet due to iron deficiency.
3. Low Energy Profile: Iron contributes in the generation of energy in the cells. Deficiency in iron lowers general levels of energy, reducing the body's ability to generate heat.
Iron Deficiency Symptoms
-Fatigue and weakness
-Pale skin
-Shortness of breath
-Dizziness or lightheadedness
-Headaches
-Brittle nails and hair loss
-Cold hands and feet
Treatment for Iron Deficiency
Iron supplements: Oral supplements of iron are often prescribed in the treatment for iron deficiency. These supplements should include the guidance of a healthcare professional.
Iron Rich Foods: This will be a very important part of increasing the intake of other iron-rich foods such as red meat, poultry, lentils, beans, tofu, and spinach. These will help with enhancing the absorption of iron from plant sources if combined with Vitamin C-rich foods (such as citrus fruits).
Iron Fortified Foods: Many cereals and breads are fortified with iron, which can be beneficial, especially for individuals on plant-based diets.
Other Factors Causing Folate and Magnesium Deficiencies
Folic Acid Deficiency
Vitamin B9 is a water-soluble vitamin that is necessary to help cell division, red blood cell maturation, and tissue growth. Folate deficiency can lead to anemia, which leads one to have cold sensitivity as a result of malfunctioning circulation and method of oxygenating tissues.
Magnesium Deficiency
It is a mineral that is activated in more than 300 enzymatic reactions within the body, including those that control blood pressure, regulate the muscles, and maintain temperature. This could mean deficiency in magnesium led to an improper flow of blood, strangulation of the muscles, and producing very cold extremities.

Conclusion: What Vitamin Deficiency Causes You to Feel Cold?
Vitamin deficiencies can greatly affect the body's capability of having warmth or regulating temperature by way of Vitamin B12, Vitamin D, or iron deficiency; all of these conditions contribute to that sense of cold dryness in the hands, feet, and other body parts. Poor flow, energy production reductions, and thermoregulation will explain the mechanisms of the symptoms.
If you commonly face experiences of having sensitivity to cold, it would be essential to check for nutrient deficiencies. You can easily discover deficiencies with the help of a blood test. Deficit correction takes place through supplementation, dietary changes, and lifestyle changes that would eventually bring back balance and hence improve overall health and comfort.
