What are Vitamin Supplements?

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.

(VeryWellHealth)

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.

(MedlinePlus)

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.

6. Vitamin facts state that taking 5 times the recommended dietary intake (RDI) of zinc, iron, selenium, and chromium can be toxic.

(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.

(LiveStrong)

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.

Facts About Vitamins and Vitamin Products

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. Some are available only in the form of a capsule or pill, while others are more efficient and work faster in liquid form.

8. Studies show that our bodies use 98% of liquid supplements.

(ConsumerLab.com, Medicare)

Moreover, the vitamin statistics reveal that liquid extracts need one to four minutes to assimilate, while pills and tablets need 20–30 minutes to break down. Liquid vitamins are better for people with digestion problems caused by gastric surgery or people who can’t swallow pills.

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

(HowStuffWorks)

Vitaminwater is packed with vitamins. Besides vitamin C, it has 20% of vitamin B3, B6, B12, and B5, each, as the vitamin water facts state. Additionally, it has 150 mg of potassium. However, vitaminwater is also packed with carbohydrates, sugar, and it has between 100 and 125 calories per serving.

10. Gummy vitamins are one of the most popular types of vitamins.

(Healthline)

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.
