Back at the beginning of the last century, in 1912, Polish scientist Kazimierz Funk first coined the term “vitamins”. It was he who discovered the B vitamins. But, at that time, scientists believed it was a single vitamin. Only later he established that it was a whole group of compounds.

The vitamin B complex is a combination of eight different essential vitamins. These water-soluble vitamin B complex benefits are important in maintaining many functions. But many of them are not only crucial for the body’s healthy functioning on a physiological level. They have far-reaching effects on mental well-being.

In this article, we’ll look at the benefits of increased intake of each vitamin B element. We will also look at the possible side effects associated with them. We’ll help you decide whether including more of them in your diet is good for you.

Vitamin B12 complex also has benefits for the immune system. It protects the body from pathogenic bacteria, viruses, and other external threats.

Besides, riboflavin promotes the production of protective cells. They protect the body from disease. That is, they help protect it from possible external invaders.

Fat-soluble vitamins such as A, D, and E take more time and effort to absorb through our diet. Riboflavin is water-soluble and relatively easy to absorb. It makes supplementation generally safe. Thus, riboflavin should consider a necessary means of strengthening the immune system.
