Home Vitamin Tests: insight into your vitamin deficiencies

All HOMED-IQ content is reviewed by medical specialists

We all know vitamins are important for maintaining good health. However, our bodies do not always get enough of them. Many people live with vitamin deficiencies, especially during the winter months when our immune system function decreases and many people stay indoors more often. But what exactly are vitamins? How do you know if you have a vitamin deficiency? In this article, you can learn more about vitamin deficiency and find out how Homed-IQ’s laboratory-certified vitamin tests can allow you to check your levels from home.

What are vitamins?

Vitamins are substances that our body needs in small amounts to function properly and to stay healthy. We obtain most vitamins through food and drinks. Vitamins are grouped into two categories: fat and water soluble. Fat-soluble vitamins are better absorbed into the bloodstream when eaten with fat and can be stored in the body’s liver, muscles, and fatty tissue. Vitamins A, D, E, and K are fat-soluble. Water-soluble vitamins dissolve in water and are carried to the body’s tissues, with excess quantities being filtered and excreted by the kidneys. Unlike fat-soluble vitamins, the body cannot store water-soluble vitamins for future use. Water-soluble vitamins include the B vitamins and vitamin C (MedlinePlus, 2022).

How a vitamin deficiency can arise

Your body cannot make most vitamins on its own, although there are a few exceptions. The best known, and perhaps most important, is vitamin D. When exposed to the sun, our body can produce vitamin D on its own. However, if an individual does not get much sun exposure, such as during the dark winter months, a deficiency of this essential vitamin can arise. Moreover, a healthy and varied diet unfortunately does not guarantee that you will get enough vitamins; sometimes you can’t get adequate vitamin intake with nutrition alone. If a deficiency exists, it is possible to take supplements in addition to dietary changes. But to implement these changes, you have to know what vitamin deficiencies are!

How do I know if I have a vitamin deficiency?

Many people are deficient in certain vitamins without noticing it. In the long run, this can lead to symptoms such as fatigue, insomnia and poor concentration. You can also get sick more easily when vitamin deficient, as certain nutrients are related to immune system function (Harvard School of Public Health, 2022). Homed-IQ’s medically certified home tests provide you with insight into your possible vitamin deficiencies without needing to visit a doctor.

Understanding a Vitamin Deficiency with Homed-IQ’s Vitamin Tests

Homed-IQ offers two different home vitamin tests: the Vitamin Deficiency Test and the Vitamin D Test. The Vitamin Deficiency Test measures the amount of vitamin B12, vitamin D and folic acid in your blood. These are all crucial vitamins that, when deficient, can lead to various unpleasant symptoms, from fatigue and hair loss to intestinal disorders.

I have a vitamin deficiency, what should I do?

Based on the results of a home vitamin test, you can know which vitamin(s) your body needs more of. You can then buy supplements or make diet and lifestyle changes to address your vitamin deficiency. By addressing vitamin deficiencies, you ensure your body has the nutrients it needs to function properly and stay healthy. By addressing vitamin deficiencies, you may feel better or alleviate certain symptoms you may have been experiencing.
