Vitamin B Complex – explained simply

The ESN Vitamin B Complex is a food supplement in tablet form designed for the daily intake of all 8 essential B vitamins. The formula is complemented with choline and myo-inositol, which functionally support B-vitamin metabolism. Vitamin B complexes are commonly used to help ensure an adequate supply of B vitamins, as these are involved in numerous metabolic and nervous system processes.1,2,3

What are B vitamins?

B vitamins are a group of 8 water-soluble vitamins that are essential for the human body. They primarily act as co-factors in energy metabolism and contribute to the normal function of the nervous system, psychological function and other fundamental metabolic processes.

Since B vitamins can only be stored in the body to a limited extent, a regular intake through diet or supplementation is important. The B-vitamin group includes vitamins B1, B2, B3, B5, B6, B7, B9 and B12.

Functions of B vitamins

Overview of the B vitamins

A complete vitamin B complex provides all 8 essential B vitamins, each fulfilling specific roles within metabolism:

  • Vitamin B1 (thiamine)
  • Vitamin B2 (riboflavin)
  • Vitamin B3 (niacin)
  • Vitamin B5 (pantothenic acid)
  • Vitamin B6
  • Vitamin B7 (biotin)
  • Vitamin B9 (folic acid)
  • Vitamin B12 (cobalamin)

The ESN Vitamin B Complex delivers all these vitamins in a carefully balanced combination and is specifically supplemented with choline and myo-inositol, which are functionally involved in B-vitamin metabolism.

Why B vitamins play a key role

Central role in metabolism

B vitamins contribute to energy production, nervous system function and normal mental performance. Thiamine, riboflavin, niacin, biotin and vitamin B12 support energy metabolism, pantothenic acid supports normal mental performance, thiamine and vitamin B12 support nervous system function, and vitamin B6 contributes to normal immune function.1,2,3,4

Increased daily demands, intensive training or an unbalanced diet may raise the need for B vitamins, making targeted supplementation beneficial.

Typical everyday use

A vitamin B complex is often used to complement daily micronutrient intake, particularly during periods of mental or physical stress. The ESN Vitamin B Complex is suitable for everyday use as well as for physically active phases, as B vitamins are involved in energy metabolism and nervous system function.

Who is a vitamin B complex suitable for?

A vitamin B complex is suitable for:

  • Athletes and active individuals
  • People with high mental or physical demands
  • Nutrition-conscious individuals
  • Vegetarians and vegans, particularly with regard to vitamin B12

The ESN Vitamin B Complex supports a reliable daily supply across different lifestyles and demands.

Key quality features of a vitamin B complex

A high-quality vitamin B complex:

  • contains all 8 essential B vitamins
  • provides carefully balanced dosages
  • ideally uses bioactive vitamin forms
  • features a transparent formulation

These factors influence both product quality and nutrient availability.

What makes the ESN Vitamin B Complex stand out

The ESN Vitamin B Complex combines all 8 B vitamins in a thoughtfully designed all-in-one formula and is enriched with choline and myo-inositol. These nutrients are traditionally associated with the B-vitamin group and are functionally involved in metabolic and cellular processes.

Thanks to selected bioactive vitamin forms and a formulation tailored to daily needs, these tablets are ideal for reliable B-vitamin support in a performance-focused lifestyle.
