Its interventions in numerous metabolic reactions make it a very important vitamin. Niacin has long demonstrated its effectiveness in treating high cholesterol and fighting skin disorders. However, both a deficiency and an excess of this vitamin can have serious consequences.
It may play a role in preventing neurological problems. It will also act as an antioxidant, meaning it can help protect the body's cells from damage caused by free radicals, potentially linked to aging and certain diseases.
Vitamin B3: benefits and roles in the body
- Niacin is involved in lipid metabolism. This vitamin has a cholesterol-lowering effect, so much so that it is frequently used to lower blood lipid levels.
- Vitamin B3 helps maintain the integrity of tissues, particularly those of the arteries, whose elasticity they preserve. In combination with other molecules, it would have a particularly interesting action in preventing atherosclerosis.
- Niacin would protect neuronal cells from premature aging and could, in this sense, prevent neurodegenerative diseases (Alzheimer's, Parkinson's, etc.)
Vitamin B3 requirements
The body's needs for this vitamin change throughout life, food intake must therefore be adapted to these changing needs to avoid niacin deficiency.
