1. Vitamins are organic compounds that are required in small amounts to sustain life. 

(Medical News Today)

Most vitamins are present in food in small quantities. Not following dietary recommendations may result in vitamin deficiency, since our bodies can’t synthesize them. All vitamins have different roles, and we need them in varying quantities.

2. There are two main groups of vitamins: fat-soluble and water-soluble.

(MedicineNet, VeryWellHealth)

The difference between fat- and water-soluble vitamins is how these vitamin groups are stored in our organism. Fat-soluble vitamins are usually absorbed in fat globules which go through the lymphatic system of the small intestines and into the blood circulation within the body. Fat-soluble vitamins are stored in body tissues.

Conversely, water-soluble vitamins do not stay in the body for long and therefore need to be replaced more often than their fat-soluble counterparts. Water-soluble vitamins are quickly absorbed into tissues to allow for immediate use.

3. The body needs 13 essential vitamins for normal cell function, development, and growth.


Our bodies require the following four types of vitamins that are fat-soluble:

  • Vitamin A
  • Vitamin D
  • Vitamin E
  • Vitamin K

We also need nine water-soluble vitamin types, and they include:

  • Vitamin B complex (B1, B2, B3, B6, Folate, vitamin B12, biotin, pantothenic acid)
  • Vitamin C

4. Our body also needs minerals to function correctly.

(OnHealth, MedlinePlus)

Our bodies need minerals for maintaining healthy bones, muscles, heart, and brain. Like vitamins, they’re also divided into two major groups: macrominerals and trace minerals (microminerals). Both groups are equally important, but we need trace minerals in smaller amounts.


5. Our bodies require 15 essential minerals.


According to the facts about vitamins and minerals, minerals are essential for making enzymes and hormones. They’re usually absorbed through food, but in some cases, there’s a need for supplementation. The essential minerals are:

  • Macrominerals that include calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur.
  • Trace minerals (or microminerals) that include cobalt, copper, fluoride, iodine, iron, manganese, selenium, and zinc.

However, depending on the medical issues and medications, some people may need different amounts of these minerals.

(Better Health Channel)

High doses of water-soluble vitamins can become toxic, and taking more folate than recommended can hide vitamin B12 deficiencies. There have been cases where people take 100 times the RDI of vitamins, stopping the work of their anticonvulsant drugs.

7. The vitamin absorption rate depends on 3 factors. 


There are very few studies on vitamin absorption rates by brand, so each company has its own claims. It’s not easy to determine the absorption rate for each product since it depends on the individual’s digestive capabilities, which change with age.

The absorption rate also depends on the enteric coating — some pills need an enteric coating as protection from stomach acids, so they can make it safely to small intestines. Moreover, the absorption of some vitamins is influenced by other nutrients. For example, calcium absorption is enhanced by vitamin D.

Vitamins and minerals are available in several forms — liquid, powder, pill, etc. The type you need depends on your preferred way of taking them and how they work with your body.

9. Vitaminwater contains 40% of vitamin C, but it also has 13 grams of sugar.

However, vitaminwater is also packed with carbohydrates, sugar, and it has between 100 and 125 calories per serving.


Gummy vitamins are chewable vitamins that come in a variety of flavors, colors, and shapes. Their taste and texture are similar to gummy candies, which makes them the perfect source of daily vitamins for children or adults who don’t prefer taking pills.

Essential Vitamins and Minerals

22. People with high amounts of vitamin A in their diet are 6% less likely to break a bone.


However, stronger bones aren’t the only benefit of a vitamin A-rich diet. Eating tuna, salmon, butter, kale, carrot, spinach, mango, and papaya, will increase the levels of vitamin A in the body. This protects your eyes from age-related macular degeneration (AMD), decreases your risk of developing certain types of cancers, and improves your immune system.

Vitamin A nutrition facts also reveal that this vitamin reduces the risk of getting acne and is essential for a healthy reproductive system.

23. There are 7 types of vitamin B.


The vitamin B complex turns food into energy. Here’s more information on its benefits:

  • Vitamins B1 and B2 can be found in cereals, potatoes, pork, seafood, and they help with energy production and enzymes that affect the muscles, nerves, and heart.
  • Vitamin B3 is found in chicken, nuts, beans, and it maintains healthy skin, digestion, and nervous system.
  • Vitamin B5 and vitamin B12 — facts reveal — are responsible for growth and development and can be found in almost all foods.
  • Vitamin B6 (pyridoxine) keeps the immune and nervous systems healthy and builds blood cells. It can be found in fish, meat, bananas, and dried beans.
  • Vitamin B7 (biotin) helps the body produce hormones, and is found in bananas, mushrooms, watermelon, grapefruit, and egg yolks.
  • Vitamin B9 (folic acid, folate) aids the production of blood cells and creates and maintains DNA. When it comes to prenatal vitamins, statistics reveal that it’s essential to take folic acid during pregnancy to aid the development of the fetus. Citrus fruits, green leafy vegetables, mushrooms, nuts, peas, and wheat bread are especially rich in vitamin B.

24. Taking 100 mg of vitamin C per day reduces the risk of cardiovascular diseases in non-smokers.


Our bodies require vitamin C for the biosynthesis of collagen, L-carnitine, and some neurotransmitters. Vitamin C is also an essential antioxidant, which regenerates other antioxidants in the body, as vitamin C facts show. Fruits and vegetables are especially rich in this vitamin.

25. Vitamin D protects us from type 1 diabetes.

(MedicalNewsToday, Holland & Barrett)

It also regulates calcium levels, keeping our bones healthy, and it protects us from the flu. Pregnant women, infants, and the elderly can benefit from vitamin D; it keeps their muscles strong, protects them from heart disease, and keeps their brain safe from dementia.

Vitamin D is one of the essential nutrients in dairy and milk, according to the vitamin D facts, but fatty fish, like tuna, salmon, and mackerel, are also rich in it, and so are mushrooms, beef liver, and fortified cereals and juices. Our body can also create vitamin D when exposed to the sun.

26. Vitamin E can help repair damaged cells.


Vitamin E is an antioxidant, and it describes eight different compounds that protect our cells from damage and prolong their life. It also gives our body protection from exposure to air pollution, cigarette smoke, and, according to the vitamin E facts, high exposure to ultraviolet rays from sunlight. Roasted seeds and nuts, boiled spinach and broccoli, kiwi, mango, and tomato are all rich in this vitamin.

27. Vitamin K improves episodic memory in the elderly.


Vitamin K is also essential for blood clotting, regulating calcium levels, and bone metabolism. It decreases the risk of bone fractures, osteoporosis, and prevents mineral build-up in the arteries. Oils, fruits, and leafy green vegetables are the best sources of vitamin K.

The CDC vitamins chart shows that babies who don’t receive a vitamin K shot at birth are 81 times more likely to develop VKDB, which leads to internal and external bleeding, causing organ damage and death.

31. Vitamin B12 deficiency can cause megaloblastic anemia.


Vitamin B12 is essential for DNA and red blood cell production. The elderly and vegans are at a high risk of developing this vitamin deficiency, which causes mouth ulcers, tongue inflammation, anemia, weakness, and blurred vision.
