Vitamins and Minerals

Vitamins and minerals are essential nutrients that the human body needs to survive and thrive. Although they are found naturally in a variety of foods, our bodies cannot produce them on their own. Vitamins and minerals play key roles in the body, helping us to support our physical and mental health.

Vitamins are organic molecules that are indispensable for life and are classified into two main groups: fat-soluble and water-soluble. Fat-soluble vitamins are stored in the body's fatty tissues and can be used when needed. They include vitamins A, D, E, and K. Water-soluble vitamins are not stored in the body, and excess amounts are eliminated from the body in urine. These vitamins include the vitamin B complex (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, and vitamin B12) and vitamin C.

Minerals are inorganic micronutrients and play an important role in many bodily functions. They can be divided into two categories: major minerals and trace minerals. Major minerals are those present in the body in relatively large amounts and include calcium, magnesium, sodium, potassium, chloride, and phosphorus. Trace minerals are required in much smaller quantities, but are nevertheless essential to health and normal body functioning. They include iron, copper, zinc, iodine, selenium, sulfur, and chromium.

Vitamins: Water-soluble vs Fat-Soluble

Vitamins play an important role in our health, but there are two major types of vitamins we need to know about � water-soluble vitamins and fat-soluble vitamins. Each type functions differently and is obtained through different foods.

Water-soluble Vitamins

Water-soluble vitamins dissolve in water, so they aren't stored in the body. This means that it is important to get a regular supply of these vitamins from the food we eat. The eight water-soluble vitamins are: Vitamin C and the B-complex vitamins including thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9) and cobalamin (B12).

  • Vitamin C helps with wound healing, tissue repair, and maintaining healthy bones and teeth.
  • The B-complex vitamins are needed for red blood cell formation and energy production.

Fat-soluble Vitamins

Unlike water-soluble vitamins, fat-soluble vitamins are absorbed into the body along with fats from the diet and are stored in the fatty tissues and the liver. This means you may consume too much of these vitamins over time if you're not careful. The four fat-soluble vitamins are A, D, E, and K.

  • Vitamin A aids in vision, immune system, and bone development.
  • Vitamin D helps the body absorb calcium and is vital for strong bones and teeth.
  • Vitamin E is an antioxidant that aids in cell repair and protection.
  • Vitamin K helps the body make proteins that are needed for strong bones, blood clotting, and normal blood flow.

Vitamin D Deficiency

Vitamin D deficiency, a common affliction, affects millions of people. While most people understand the benefits of vitamins and minerals, many are unaware of the possible health conditions caused by vitamin D deficiencies. This deficiency can cause serious issues for patients who don�t get the proper treatment.

Causes of Vitamin D Deficiency

Vitamin D deficiency is caused by a lack of exposure to sunlight and inadequate intake of vitamin D rich foods. Risk factors for vitamin D deficiency include the following:

  • Darker skin complexions absorb less sunlight
  • Location in areas with limited year-round sunlight
  • Spending prolonged periods of time inside (e.g., elderly, shift work)
  • Having certain digestive disorders or obesity
  • Having liver or kidney disorders

Manifestations of Vitamin D Deficiency

Vitamin D plays an important role in keeping the body functioning properly. It helps regulate calcium and phosphorous levels in the blood and assists the body in absorbing these minerals. Without adequate levels of vitamin D, symptoms such as fatigue, depression, bone pain, muscle weakness, impaired wound healing, and increased risk of infection can develop.

Treatment Options

Treatment of vitamin D deficiency usually involves increasing dietary intake of vitamin D-fortified foods, supplements, or both. In some cases, treatment may require taking large doses of vitamin D as prescribed by a healthcare professional. These treatments should be taken under the supervision of a doctor to ensure proper dosing and to avoid potential side effects.

It is important to note that correcting vitamin D levels requires continuous and regular intake of either fortified foods or supplements. Patients should discuss their treatment options with a doctor to determine the best course of action for them.


Minerals are essential nutrients for optimal health that are found in all living things. They come in two forms: major and trace minerals. Major minerals are macro-minerals, meaning they are needed in larger amounts and provide the body with energy, but are not produced naturally in the body. Trace minerals, or micro-minerals, are needed in smaller amounts but are still essential for a number of bodily functions.

Major Minerals

The six major minerals that the body needs are calcium, phosphorus, magnesium, potassium, sodium, and chloride. Each of these minerals has an important role to play in maintaining good health. For example, calcium is essential for the development and maintenance of strong bones and teeth, while magnesium helps to regulate blood sugar levels and reduce stress.

Trace Minerals

The body also needs small amounts of trace minerals to maintain optimal health. These include iron, copper, zinc, iodine, selenium, sulfur, and chromium. Each of these trace minerals plays a specific role in the body such as helping to produce energy, regulating metabolic processes, and aiding in the body�s ability to absorb other minerals.

Difference between Major and Trace Minerals

The main difference between major and trace minerals is the amount of each required by the body. Major minerals are required in larger quantities, while trace minerals are needed in much smaller amounts. In addition, major minerals are involved in many different bodily functions, while trace minerals focus on a few specific processes.

Trace Elements

Trace elements are a group of minerals that are important for the health of our bodies. They can be divided into two categories; major and trace minerals. The trace elements are found in smaller amounts in the body and include iron, copper, zinc, iodine, selenium, sulfur and chromium. Below is more information about each mineral and their potential deficiency/toxicity.


Iron is an essential mineral for the human body, as it is required for the formation of hemoglobin and myoglobin in red blood cells. It is also important for cellular respiration and proper functioning of the immune system. Iron is found in foods such as legumes, whole grains, liver, eggs, fish, poultry, nuts, and leafy green vegetables. Iron deficiency is the most common nutrient deficiency and can cause anemia, fatigue, dizziness, headache, insomnia, weakened immune system, and irritability. Iron overload or toxicity can be caused by disorders like hemochromatosis, polycythemia vera, and thalassemia.


Copper is an essential trace mineral important for normal body functioning. It helps form collagen, maintain nerve cells, and is a necessary component of many enzymes. Copper can be found in foods such as oysters, clams, mussels, organ meats, sunflower seeds, almonds, walnuts, black pepper, garlic, mushrooms, and cocoa. Copper deficiency is rare but may occur in patients with malabsorption syndromes. Copper toxicity can result from increased absorption of copper due to Wilson's disease.


Zinc is an essential trace mineral involved in many processes in the body such as the metabolism of carbohydrates, proteins, lipids, hormones, and vitamins. It plays a role in wound healing, immunity, fertility, growth, and development. Zinc is found in foods like oysters, beef, lamb, crab, pork, chicken, yogurt, eggs, and cashews. Zinc deficiency symptoms include poor growth, impaired immune function, diarrhea, hair loss, impaired sense of taste and smell, and skin lesions. Toxicity from zinc is rare, but symptoms include nausea, vomiting, fever, abdominal pain, and diarrhea.


Iodine is an essential trace mineral involved in several metabolic processes, including the production of thyroid hormones. It is found in iodized salt, seaweed, dairy products, eggs, fish, shellfish, and some vegetables. Iodine deficiency is common in many parts of the world and can cause goiter, hypothyroidism, mental impairment, delayed growth and development, and cretinism. High levels of iodine can also cause adverse effects such as thyroid dysfunction, dermatitis, and goiter.


Selenium is an essential trace mineral involved in many different bodily functions including metabolism, antioxidant activity, and immune function. It is found in Brazil nuts, tuna, halibut, cod, beef, turkey, shrimp, tiny shrimp, wild-caught salmon, cottage cheese, eggs, lentils, and oats. Selenium deficiency symptoms include cardiovascular disease, cognitive decline, infertility, and immune dysfunction. High levels of selenium can be toxic, causing hair loss, joint pain, fatigue, nail changes, and mild nerve damage.


Sulfur is an essential trace mineral involved in the formation of proteins, amino acids, and enzymes. It can be found in all tissues of the body and in foods such as eggs, fish, poultry, and vegetables. Sulfur deficiency is rare but can cause impaired growth, poor wound healing, and decreased immune function. Sulfur toxicity is also rare but can cause skin irritation, nausea, and vomiting.


Chromium is an essential trace mineral important for glucose metabolism, insulin sensitivity, and fat and carbohydrate metabolism. It can be found in foods such as brewer's yeast, broccoli, potatoes, turkey, green beans, whole-grain breads, English muffins, molasses, and oatmeal. Chromium deficiency is uncommon and symptoms may include impaired glucose intolerance, depression, and difficulty concentrating. High levels of chromium may lead to kidney and liver damage.

Prevention of Vitamin and Mineral Deficiencies

Ensuring a healthy and balanced diet is the best way to prevent vitamin and mineral deficiencies. Eating a variety of fresh, organic whole foods, such as fruits, vegetables, whole grains, and lean proteins, will supply your body with essential nutrients. Try to focus on unprocessed foods whenever possible, as these are often richer in vitamins and minerals. Additionally, some individuals may benefit from taking a daily multivitamin or supplementing with specific vitamins and minerals.

Certain foods can provide high levels of particular vitamins and minerals. For example, shellfish, liver, and egg yolks are rich sources of iron; dairy products, fish, and egg yolks contain high levels of calcium; red meats, legumes, nuts, and eggs provide good amounts of zinc; and various fruits and vegetables have high levels of vitamin C. Many fortified breakfast cereals also exist that supply additional vitamins and minerals.

It is important not to over-restrict your diet, as this can lead to deficiencies. Speak to a doctor or health professional if you have any concerns about a particular deficiency, as they can provide advice on how best to address it.

Signs and Symptoms of Vitamin and Mineral Deficiencies

Vitamins and minerals are essential to the normal functioning of the body, and deficiencies can cause a variety of health problems. The most common symptoms of deficiencies include fatigue, weakened immune system, poor digestion, and lack of concentration. It is important to recognize these symptoms so that adequate amounts of vitamins and minerals can be consumed in order to prevent serious health issues.

Fatigue is one of the most common signs of vitamin and mineral deficiency. As the body does not have enough essential nutrients, it is not able to properly supply the cells with enough energy for normal functions. As a result, people feel tired and listless much of the time.

The immune system also depends on adequate amounts of vitamins and minerals. Without them, the body's ability to defend itself against pathogens and other invaders is weakened. This can lead to frequent infections and illnesses.

Poor digestion is another sign of deficient nutrients. Vitamins and minerals play an important role in the process of breaking down food into smaller molecules that can be utilized by the body. When the digestive system cannot do the job efficiently, many health issues such as bloating, constipation, and nausea can occur.

Finally, lack of focus and concentration is a major symptom of nutritional deficiency. Not getting the right nutrients affects the brain and its ability to think quickly and efficiently. This can lead to difficulty completing tasks and reduced overall productivity.

It is important to be aware of these signs and symptoms so that proper nutrition can be ensured. A healthy diet, balanced with the right amounts of vitamins and minerals, is essential for optimal health.
