Vitamin B12 is a so-called essential vitamin. This means that the body cannot produce it or cannot produce it to a sufficient degree by itself. Vitamin B12 can be produced in very small amounts by bacteria in the small intestine. Without a regular supply of vitamin B12 via food, human health can be adversely affected. Tiredness, exhaustion, headaches, difficulty concentrating, digestive problems and depression can all be signs of a low vitamin B12 level. People with high stress levels, vegans, vegetarians, pregnant women and seniors all have an increased risk of vitamin B12 deficiency.
Vitamin B12 is involved in cellular energy production and can thus support physical performance.
