You need all 13 essential vitamins to stay healthy. The following are the vitamins you should take to keep your body healthy:

What Vitamins Should I Take?

When you don’t get the adequate amounts of particular vitamins, you may get certain deficiency diseases. For instance, insufficient quantities of B6 or B12 may lead to anemia while too little vitamin D may cause rickets or a weak-bone illness in children. These examples illustrate that each vitamin has a specific purpose in your body. It is beneficial to try to take all of them though not necessarily every day.

However, taking too much of any vitamin can lead to problems. For example, taking excess vitamin B6 can cause symptoms such as trouble walking and nerve damage. Excess amounts of vitamin D may cause heart arrhythmias.

The best way to ensure you get the right amount of vitamins is by consulting your doctor or nutritionist. If you lack certain amounts, the best remedy is to take the proper dosages of vitamin supplements.

What Do Vitamins Do?

All vitamins are essential nutrients since they perform several roles in your body. Therefore, missing any one of them for an extended period may cause your body to fail to function correctly and trigger some diseases. For instance, vitamins heal wounds, strengthen bones, and boost your immune system. Another function is converting food into energy while repairing cellular damage. Vitamin deficiency disorders result if you don’t take adequate vitamins.

There are two categories of vitamins, the water-soluble vitamins and the fat-soluble vitamins.

What Are Fat-Soluble Vitamins

Fat-soluble vitamins are stored in your body’s fat tissue for up to several months. These vitamins include vitamins A, D, E, and K. They are rich in high-fat foods and are absorbed more easily into your bloodstream when you consume such foods. Because these vitamins are fat-soluble, they will be stored in the liver or fat cells and later excreted through the lymph system.

Some of the significant functions of these vitamins include building bones, protecting your vision, and keeping your cells healthy. They also act as antioxidants by protecting your body from the damage of unstable molecules. Additional functions include maintaining the skin, lungs, nervous system, and gastrointestinal tract.

What Are Water-Soluble Vitamins

These are vitamins stored into the watery portions of the consumed foods. Their absorption occurs directly into the bloodstream during food digestion or as their supplements dissolve in body fluids.

Water-soluble vitamins classification includes all the B complex vitamins such as B5, B1, B2, B6, B3, B7, B12, folic acid, and vitamins C.

Since most of your body consists of water, transportation of water-soluble vitamins happens efficiently in the bloodstream. Your kidneys perform consistent regulation and balance of their levels and excrete excess amounts out of the body through your urine.

There are many functions of water-soluble vitamins, but the important one is to release the energy from the food you eat. Others maintain healthy tissues.

What Are Prenatal Vitamins?

Prenatal vitamins consist of various nutrients that give your baby the essential nutrients for healthy development.

Prenatal vitamins typically contain more folic acid and iron than do standard adult multivitamins. The main reason is that folic acid prevents neural tube abnormalities such as severe defects of the spinal cord and the brain. Alternatively, iron prevents anemia and supports proper growth and development of the baby including healthy adult life.

Additionally, some research indicates that prenatal vitamins reduce the risk of having babies who are small for their gestational age.

What Vitamins Do You Get From the Sun?

This process can prevent the formation of dark spots and wrinkles.

The primary function of vitamin K is to control certain skin conditions such as stretch marks, scars, spider veins, and dark spots.

Vitamin B3

Vitamin B3 or niacin is essential for healthy skin. Research indicates that vitamin B3 can significantly lessen the appearance of aged skin. Many top skin brighteners have its ingredient added for such purposes.

Vitamin B5
