All About Water-Soluble Vitamins
Vitamin tablets that easily dissolve in water are known as water-soluble vitamins. These vitamins are carried to the body's tissues and are not stored in the body.
Vitamins B and C are water-soluble. They can keep your body healthy, help in energy production, and build your immune system.
What are Vitamins?
Vitamins are essential nutrients that the body needs in small amounts to function properly and stay healthy. They help in energy production, strengthen the immune system, support growth and development, and keep organs working well. Since the body cannot produce enough vitamins on its own, they must be obtained from food sources such as fruits, vegetables, grains, dairy products, and supplements if required. There are two main types of vitamins: water-soluble (like Vitamin C and B-complex) and fat-soluble (like Vitamins A, D, E, and K).

Water-soluble vitamins, such as Vitamin C and the B-group, are important nutrients that dissolve in water and are absorbed into the blood. They help the body make energy from food, keep the nerves and brain healthy, build strong immunity, and maintain healthy skin and red blood cells. Unlike fat-soluble vitamins, these are not stored in the body for long. Any extra amount is passed out through urine. Because of this, it is important to eat foods rich in these vitamins every day, like fruits, vegetables, grains, and pulses, to keep your body active and healthy.

Water Soluble Vitamins and Their Deficiency
Vitamin B1 (Thiamine):
This is the first water-soluble vitamin that was discovered. There are various types of thiamine:
- Thiamine pyrophosphate: The most abundant form of thiamine in the body, also naturally present in whole foods.
- Thiamine triphosphate: A less common form found in animal foods, accounting for less than 10% of the total thiamine present in animal tissue.
- Thiamine mononitrate: A synthetic form of thiamine often added to animal food products.
Deficiency:
- High sugar levels can increase thiamine elimination and can increase the risk of deficiency.
- People who drink alcohol are at high risk of deficiency. It is due to poor diet and impaired thiamine absorption.
- Some serious deficiencies can cause some major disorders such as beriberi.
- Various symptoms that can be seen are weight loss, mental problems and muscle weakness.
People can benefit from taking high-dose supplements that help reduce blood sugar and blood pressure. Vitamin B1 helps in metabolic processes that convert nutrients into energy.
Some of the richest dietary sources of thiamine include liver, pork, seeds, and whole-grain cereals.
Vitamin B2 (Riboflavin):
This is a water-soluble vitamin that can be used as a food colouring. There are various types of Riboflavin.
- Dietary substances are also known as flavoproteins. It releases riboflavin during digestion.
- Flavin adenine dinucleotide and Flavin mononucleotide can be found in a variety of foods.
Deficiency:
Riboflavin deficiencies are found very rarely in developed countries.
- Poor diet, old age and lung diseases can increase the risk.
- Some severe deficiencies can cause ariboflavinosis, which may lead to sore throat, inflamed tongue and skin problems.
People who are already taking enough food can avoid taking riboflavin supplements. But if vitamin B2 is low in our body then it may reduce the blood pressure and also reduce the risk of heart disease. A high dose of riboflavin will help in reducing migraines.
Vitamin B3 (Niacin):
Niacin is a vitamin that the body can produce from other nutrients i.e., amino acid tryptophan.
Types:
- Nicotinic acid: This acid is found in both plant—and animal-sourced foods. A high dose can cause a condition called niacin flush.
- Nicotinamide: It can be found in supplements.
Deficiency:
- The symptoms it shows are inflamed skin, mouth sores, diarrhea, insomnia, and dementia.
- Cereal grain is low in niacin.
Some benefits niacin can provide are:
- They help in bringing down the high levels of low-density lipoprotein cholesterol (bad).
- Raise high-density lipoprotein levels (good).
Vitamin B3 is found in many foods, including liver, fish, poultry, eggs, and daily dairy products. People eating low-protein diets are at a higher risk of deficiency.
Vitamin B5 (Pantothenic Acid):
These can be found in all foods. There are various types of pantothenic acid:
- Coenzyme A: A common source of vitamins found in food. It releases acid in the digestive tract.
- Acyl carrier protein: Also known as coenzyme A, it is present in many foods and can release acid in the digestive tract.
- Panthenol: A form of pantothenic acid that is often used as a supplement.
Deficiency:
- This deficiency can be found rare in industrialized countries.
- There is an adverse effect that can be seen in many parts, such as numbness, irritability, restlessness, and digestive problems.
Vitamin B6:
- Pyridoxine: Pyridoxine can be found in various fruits, vegetables, and grains as supplements.
- Pyridoxamine: This is a common type of Vitamin B6 that is present in animal-sourced foods.
Deficiency:
- Vitamin B6 can be found rarely. People who are addicted to alcohol can be at greater risk.
- The symptoms include anemia, skin rashes and depression. Some large doses of pyridoxine are used to treat carpal tunnel syndrome.
- Specifically, this should be taken with a doctor's prescription.
Vitamin B7 (Biotin):
These supplements nourish the hair, nails, and skin. Proteins that consist of biotin when releasing a compound can be preferred as biocytin.
- Untreated biotin symptoms may show neurological symptoms.
- These are also found in animals that are fed high amounts of raw egg whites.
Deficiency:
Biotin supplements help in improving health. These may improve symptoms in people with multiple sclerosis and brittle nails.
Vitamin B9:
This was discovered from yeast but later was isolated from spinach. Various types of Vitamin B9:
- Folate: The natural form of vitamin B9 that occurs naturally in foods.
- Folic acid: The synthetic form of vitamin B9 added to processed foods. High doses may be harmful to the body.
Deficiency:
- These occur on their own and are associated with nutrient deficiency and poor diet.
- Vitamin B9 anaemia is a common symptom. Deficiency can lead to birth effects on the brain, which can be called neural tube defects.
- Some studies suggest that supplements can reduce the risk of heart disease and also help control blood sugar.
Vitamin B12 (Cobalamin):
Vitamin B12 contains the metallic element cobalt, which is also known as cobalamin. There are various types of Vitamin B12, including cyanocobalamin, hydroxocobalamin, adenosylcobalamin, and methylcobalamin.
Deficiency:
- Vegetarian people can face some deficiency symptoms.
- Deficiency may also develop in older people. Vitamin B12 can be found rarely in some people.
Vitamin C:
- This is the only water-soluble vitamin that is not included in the vitamin B category. Ascorbic acid is one form of Vitamin C.
- This is the only water-soluble vitamin that is not included in the vitamin B category. Ascorbic acid is one form of Vitamin C.
Deficiency:
- The deficiency can be found mainly in people who don't eat fruit and vegetables.
- It can lead to some diseases known as scurvy.
- Fatigue and weakness are some of the main symptoms found in a person.
Vitamin C helps improve iron absorption from the meal and also helps people who have low or deficient iron. These also help lower blood pressure and can reduce the risk of heart disease.
Examples of Water-Soluble Vitamins
Water-soluble vitamins are nutrients that dissolve in water and are not stored in the body for long, so they need to be taken regularly through food. The main examples include:
- Vitamin C - important for immunity, wound healing, and healthy skin.
- Vitamin B1 (Thiamine) - helps convert food into energy.
- Vitamin B2 (Riboflavin) - supports growth, energy, and eye health.
- Vitamin B3 (Niacin) - aids digestion and nerve function.
- Vitamin B5 (Pantothenic Acid) - helps make hormones and energy.
- Vitamin B6 (Pyridoxine) - supports brain development and immunity.
- Vitamin B7 (Biotin) - good for hair, skin, and nails.
- Vitamin B9 (Folic Acid) - essential for blood formation and pregnancy health.
- Vitamin B12 (Cobalamin) - important for nerves and red blood cell production.
Since these vitamins are not stored in the body, a balanced diet with fruits, vegetables, whole grains, dairy, and lean proteins is necessary to meet daily needs.

Schedule Your AppointmentWater-Soluble Vitamins Functions
Water-soluble vitamins like Vitamin B-complex and Vitamin C play key roles in keeping the body healthy. They help convert food into energy, support brain and nerve function, boost immunity, maintain healthy skin, and aid in red blood cell formation. Since the body does not store these vitamins, regular intake through diet or supplements is essential to prevent deficiencies.
Fat-soluble vitamins include Vitamins A, D, E, and K. These dissolve in fat and are stored in the liver and fatty tissues, meaning the body can use them when needed.
