Almost everyone believes they know what vitamins are. The truth is that most don’t. There’s a good chance you’re guilty of thinking the definition of vitamin is just something you heard in high school or read on a cereal box once but never actually knew for sure.
Vitamins – also called essential nutrients – are substances found naturally in food and used by the body to stay healthy and help fight off diseases and infections. They’re necessary because our bodies can’t make them, so we need to get them from the food we eat, which explains why it’s essential to eat an assortment of different foods every day to get all the necessary vitamins your body needs.
To get the most out of vitamins, you’ll want to break down their different roles in the body. There are four major essential nutrients that your body needs – vitamin A, vitamin B, vitamin C, and vitamin D. Each serves a particular purpose for helping keep you healthy, so it should be no surprise that people who have deficiencies in these vitamins can develop serious health problems if they don’t start eating better or taking supplements.
Here is what each of these four vitamins does for you.
One of the most important roles of vitamin A is that it helps keep your immune system healthy. If you have high levels of this nutrient in your body, you’re less likely to get sick with viruses or bacterial infections. Another significant benefit of vitamin A is its role in keeping your eyes and skin healthy.
An exciting fact about vitamin A is how it keeps your vision working correctly. If you have a vitamin A deficiency, chances are, you might experience dryness in the cornea of the eye – which is where we get the phrase “corneal dryness.”
There are eight different forms of vitamin B, all of which work together to help break down proteins and fats into energy your body can use. If you’re not getting enough vitamin B in your diet, you can experience various symptoms like lack of appetite, fatigue, and insomnia. Vitamin B complex helps regulate the sleep cycle and stimulate erythropoietin production in the kidneys.
A lack of vitamin B in your system is related to symptoms like fatigue and insomnia because this nutrient helps regulate your digestive system. However, if you’re experiencing serious sleep-related problems, consulting a sleep provider is the best thing to do.
What It Does- Vitamin C is one of the most widely talked about vitamins because its benefits are so numerous and impact your life in such a positive way. First, it helps keep your immune system healthy like vitamin A does – which means you’re less likely to get sick or deal with colds.
Vitamin C also plays a significant role in developing collagen – which is something you need for healthy hair, skin, and nails. Because vitamin C is so good for your body, it’s not uncommon to see people take vitamin supplements to get daily doses.
Vitamin D is a unique nutrient because it does not have any functions in your body until it gets activated by ultraviolet light from the sun or an artificial source like tanning beds or lamps. For this reason, many people get their daily required amount of vitamin D from these sources.
Once activated by the sun or other artificial sources, vitamin D works to keep your bones healthy and strong by helping you absorb calcium. If you don’t have enough vitamin D in your body, it can lead to issues with the bones, like softening of the bones.
As you can see, the four major vitamins your body needs to stay healthy all serve very different roles. If you don’t start eating more foods that contain these nutrients or take supplements, it’s only a matter of time before your health starts to suffer because of it. For this reason, supplementing with multivitamins and other vitamin-specific products is one of the best things you can do for yourself and your family. By taking care of yourself and getting enough sleep, you give yourself the opportunity to live a fulfilling life without worrying about your health as much as those who neglect their bodies.
