What Are the 13 Essential Vitamins and Why Do They Matter?

Vitamins play an important role in everyday health, but many people do not know what each vitamin does. When choosing a multivitamin, it can be difficult to understand whether a product offers complete support or only covers a small selection of nutrients.

At ProVen Vitamins, we believe daily nutrition should feel clear, simple and easy to understand. A good multivitamin should help support your everyday needs with a full range of essential vitamins in a format and at a level that fits into real life.

That is why our Adults A-Z multivitamins and Kids A-Z multivitamins contain all 13 essential vitamins. They give adults and children complete daily vitamin support in delicious chewable tablets that are easy to take.

In this article, we explain what the 13 essential vitamins are, why they matter and how ProVen Vitamins can help make daily support simple for the whole family.

What are the 13 essential vitamins?

The 13 essential vitamins are:

  • Vitamin A

  • Vitamin B1 (Thiamine

  • Vitamin B2 (Riboflavin)

  • Vitamin B3 (Thiamine)

  • Vitamin B5 (Pantothenic Acid)

  • Vitamin B6 (Pyridoxine)

  • Vitamin B7 (Biotin)

  • Vitamin B9 (Folic Acid)

  • Vitamin B12 (Cobalamin)

  • Vitamin C

  • Vitamin D

  • Vitamin E

  • Vitamin K

Each vitamin supports the body in a different way. Some help support energy release, while others contribute to immune function, bones, skin, vision, cells, and general wellbeing.

Because the body needs different vitamins for different functions, a complete multivitamin can be a practical way to support daily intake. Rather than focusing on one single nutrient, ProVen Vitamins A-Z chewables bring all 13 essential vitamins together in one convenient daily tablet.

Why does vitamin A matter?

Vitamin A helps support several important functions in the body. It contributes to normal vision, normal skin, and normal immune function, as well as supporting iron metabolism, and normal mucous membranes.

Both our Adult A-Z multivitamins and our Kids A-Z multivitamins include vitamin A as part of a complete formula designed for children’s everyday needs.

Why does vitamin B1 matter?

Vitamin B1, also known as thiamine, contributes to normal energy-yielding metabolism. This means it helps the body release energy from food.

Adults and children both need energy to get through busy days. From work and family life to school, play and activities, daily routines can place demands on the body.

Thiamin also contributes to normal functioning of the nervous system, to normal psychological function, and to the normal function of the heart. Including vitamin B1 as part of a complete formula, ProVen Vitamins helps support everyday nutritional intake in a simple chewable format.

Why does vitamin B2 matter?

Vitamin B2, also known as riboflavin, supports normal energy-yielding metabolism and contributes to the reduction of tiredness and fatigue.

It also contributes to the maintenance of normal skin, normal mucous membranes, and normal vision, as well as normal function of the nervous system. 

Our A-Z multivitamins include vitamin B2 alongside the other essential vitamins, giving adults a complete daily formula in one orange-flavoured chewable tablet.

Why does vitamin B3 matter?

Vitamin B3, also known as niacin, helps support normal energy release and contributes to the reduction of tiredness and fatigue, as well as supporting the nervous system.

It also supports normal psychological function and the maintenance of normal skin. This makes it a valuable vitamin for adults with busy schedules and children with active routines.

A complete A-Z multivitamin can make it easier to support regular intake. ProVen Vitamins includes vitamin B3 in our adult and children’s chewable multivitamins, helping make daily support simple.

Why does vitamin B5 matter?

Vitamin B5, also known as pantothenic acid, contributes to normal mental performance and helps support energy-yielding metabolism.

It also contributes to the reduction of tiredness and fatigue and to the normal synthesis and metabolism of steroid hormones, vitamin D and some neurotransmitters. For adults balancing work and home life, this can be an important part of everyday support. For children, it forms part of a broad vitamin intake that supports their daily needs.

By including vitamin B5 in our A-Z multivitamins, ProVen Vitamins helps provide a more complete daily formula than products that only focus on a few headline nutrients.

Why does vitamin B6 matter?

Vitamin B6 supports normal energy-yielding metabolism and contributes to the normal function of the immune system. It also helps support normal psychological function and contributes to the reduction of tiredness and fatigue.

Because vitamin B6 supports several daily functions including the above and a range of others, such as the regulation of hormonal activity and normal nervous system function, it is commonly found in complete multivitamin formulas.

Our Adults A-Z multivitamins include vitamin B6 as part of all 13 essential vitamins, giving adults a convenient way to support everyday nutrition.

Why does vitamin B7 matter?Why does vitamin B9 matter?

Vitamin B7 is generally known as biotin and not B7. It contributes to normal energy-yielding metabolism, normal macronutrient metabolism (carbohydrates, protein and fat), and normal psychological function.

Like many of the other vitamins it is also known to have a wide range of roles in the body, including contributing to the maintenance of normal hair, mucous membranes, and skin.

Biotin is found in both our Adult and Child A-Z multivitamins and forms part of the whole B vitamin complex to support daily health.

Why does vitamin B9 matter?

Vitamin B9, also known as folic acid, contributes to normal psychological function and supports normal immune system function. It also plays a role in the process of cell division.

Folic acid is one of the essential B vitamins included in complete A-Z multivitamin formulas. It works alongside other B vitamins to help support everyday wellbeing.

For children and adults, getting a broad range of B vitamins can help support health. ProVen Vitamins includes folic acid in both our adult and children’s A-Z multivitamins.

Why does vitamin B12 matter?

Vitamin B12 contributes to normal energy-yielding metabolism, normal immune function, and the reduction of tiredness and fatigue. It also supports normal psychological function and the normal formation of red blood cells.

Many adults actively look for B12 in a multivitamin because of its role in energy release and fatigue reduction. Our Adult A-Z Multivitamins include an added boost of B12, helping adults keep daily nutrition on track.

The chewable format also makes it easier to take consistently. Instead of swallowing a large tablet, adults can enjoy a delicious orange-flavoured chewable that dissolves in the mouth.

Why does vitamin C matter?

Vitamin C is one of the most recognised vitamins for immune support. It contributes to the normal function of the immune system and helps protect cells from oxidative stress.

It also supports normal collagen formation, which matters for the normal function of skin, bones, cartilage, teeth, and gums.

Children and adults both need vitamin C as part of a varied diet. By including vitamin C in our A-Z multivitamins, ProVen Vitamins helps support everyday immune health in a simple and convenient way.

For children who need more targeted immune support, ProVen Vitamins also offers Kids Immunity with Vitamin C, D and Elderberry.

Why does vitamin D matter?

Vitamin D contributes to the maintenance of normal bones, teeth, and muscle function. It also supports normal immune function in both adults and children.

In the UK, vitamin D is especially important because sunlight levels can be limited during autumn and winter. Many adults and children spend more time indoors during colder months, which can make vitamin D supplementation a useful part of a daily routine.

Our Kids A-Z multivitamins include vitamin D as part of a complete children’s formula. Our Adult A-Z Multivitamins also include vitamin D alongside the other essential vitamins, helping adults support daily intake in an easy chewable format.

Why does vitamin E matter?

Vitamin E helps protect cells from oxidative stress. This means it contributes to the protection of cells from damage caused by free radicals.

It is an important vitamin for general wellbeing and forms part of a complete essential vitamin profile.

When choosing a multivitamin, it is useful to look for a formula that includes vitamin E alongside vitamins A, B, C, D and K. This helps provide broader daily support rather than a narrow selection of nutrients.

Why does vitamin K matter?

Vitamin K contributes to normal blood clotting and the maintenance of normal bones. This makes it an important part of a balanced vitamin intake.

It works alongside other nutrients, including vitamin D, to support bone health. For adults and children, vitamin K forms part of the complete essential vitamin profile included in ProVen Vitamins A-Z chewables.

Our Adult and Kids A-Z Multivitamins include vitamin K as one of all 13 essential vitamins, giving you a simple way to support daily intake.

Why choose a complete multivitamin?

A complete multivitamin can help make daily vitamin support easier. Instead of taking several different products or trying to work out which nutrients you may need, an A-Z formula brings the essential vitamins together.

This is useful for adults with busy lifestyles and parents who want a simple way to support their children’s daily nutrition.

Our Adults A-Z multivitamins provide 100% daily nutrition in an orange-flavoured chewable tablet. Our Kids A-Z multivitamins provide all 13 essential vitamins in a raspberry-flavoured chewable made especially for children.

Both products help make daily support simpler, tastier and easier to maintain.

Why chewable tablets make daily vitamins easier

A complete formula matters, but format matters too. A multivitamin can only support your routine if you take it consistently.

Traditional tablets can be hard to swallow and may leave a bitter taste. Gummies can be appealing, but they may contain added sugar or lower levels of active ingredients.

ProVen Vitamins chewable tablets offer a better balance. They are easy to take, dissolve in the mouth and provide fruity flavours adults and children can enjoy.

Our chewable tablets are deliberately delicious and naturally effective, helping make daily vitamins feel less like a chore and more like a simple part of the day.
