Niacin (Vitamin B3) - What it is, effects & 10 incredible benefits

Niacin, or vitamin B3, is a very important nutrient for our body. We explain below what niacin is, what health benefits it has and how it affects your body. Did you know that niacin can even improve your sleep quality and help with depression?

What is niacin (vitamin B3)?

Niacin, also known as vitamin B3, is a water-soluble vitamin and belongs to the group of B vitamins. More precisely, it consists of various compounds and is, therefore, to be understood as a collective term. It is composed of nicotinic acid and nicotinamide. Niacin is involved in various processes in the body, such as energy metabolism and cell division.

Which foods contain niacin?

Niacin can be obtained through a normal and balanced diet. Even as a vegan/vegetarian, the recommended daily dose of 13 - 18 mg can be covered through diet. Many plant foods contain vitamin B3. These include legumes, potatoes, peanuts, cashews, dates, mushrooms and whole grain products.

But our One Bear A Day Immune Vitamins also contain 8mg of niacin and six other important vitamins per recommended daily amount. This is equivalent to 50% of your daily niacin requirement. So, you get a multivitamin kick every day. They are also sugar-free and taste deliciously of raspberry, blueberry and orange.

What effect does niacin have?

As already mentioned, vitamin B3 is involved in many processes, such as cell division and energy metabolism. In addition, it is said to have a positive effect on mental health and reduces fatigue. Niacin is also very popular in skin care. Niacinamides are said to improve the appearance of the skin by helping to renew the skin's surface, acting as an antioxidant and moisturising. Vitamin B3 is also an important vitamin for hair because it strengthens the hair structure, prevents excessive sebum production and protects the scalp from inflammation, for example. But niacin also plays a role in sleep because an insufficient supply is said to lead to sleep disorders.
