Vitamin B2/B3 is a combination product to support energy production in the cells. Vitamin B2 plays a role in the maintenance of the nervous system, digestion and energy management. It is also important for healthy skin and eyesight. Vitamin B2 contributes to the protection of the cells in the body against oxidative damage.
In case of a vitamin B2 deficiency, skin inflammation can develop, especially at the corners of the mouth. A vitamin B2 deficiency can lead to a decrease in hemoglobin levels and can cause fatigue symptoms.
Vitamin B3 contributes to normal energy-yielding metabolism, to the maintenance of normal skin and mucous membranes. It contributes to brain and nerve functions involved in learning ability. It has a beneficial effect on the reduction of fatigue and fatigue, and contributes to normal functioning of the nervous system.
Vitamin B3 is found in various foods: meat and fish, poultry, nuts, seeds and grain products. In addition, the body can partially make vitamin B3 from the amino acid tryptophan (building block of proteins). As a result, protein-rich products such as dairy products and eggs also contribute to the production of niacin (via the conversion of tryptophan).
Vitamin B3 occurs in two forms: nicotinic acid and nicotinamide. No adverse effects are known for the use of large amounts of nicotinamide. This form is generally used in supplements and fortified foods. Nicotinic acid, which may also be used for this, can cause a red rash of the skin (flushing). This has no serious consequences.
Vitamin B2/B3 contains a special form of niacin, inositol hexanicotinate, consisting of 6 molecules of niacin linked to inositol. In the body this compound is hydrolyzed very slowly to inositol. This releases this substance very slowly in the body, and prevents people who swallow vitamin B3 from getting a red rash.
