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.
NASSIM JAMALZADEH:
"Niacin is not only important for the immune system but also plays a crucial role in cell division, energy metabolism, mental health and skin care. Niacin, as you can see, is an all-rounder and its effects should definitely not be underestimated."
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.

ALL QUESTIONS ABOUT NIACIN
ALL QUESTIONS ABOUT NIACIN
Can there be an overdose of niacin?
Overdosing on the ingredient nicotinamide hardly causes any side effects. However, if you take several grams of nicotinic acid, you may experience side effects such as nausea, vomiting or diarrhoea. In the worst case, long-term damage can even occur, such as problems with the liver. So-called "flush symptoms" can also occur. These are, for example, reddening of the skin and feelings of heat or hives.
How much niacin do you need daily?
Although niacin can be produced by the body, it is still important to consume the recommended daily amount through food. Adults are recommended to take 13 - 18 mg daily. The values for infants are between 2 and 5 mg and for children and adolescents between 8 - 13 mg. However, the daily amount varies slightly depending on age and gender.
What are the effects of a niacin deficiency?
A niacin deficiency is rather rare in this country, but it can be caused, for example, by chronic diseases such as anorexia, diarrhoea, cirrhosis of the liver or a very unbalanced diet. Signs that a deficiency is present are symptoms such as: weakness, digestive disorders, loss of appetite but also depression and dementia.
How important is niacin for newborns and children?
Since niacin is involved in many processes, such as metabolic processes, as already mentioned several times, the sufficient supply for newborns and children is just as important as that for adults.
What is the difference between niacinamide and niacin?
Niacinamide is a form of vitamin B3 that has a different chemical structural formula than niacin. In addition to niacinamide, there is also the so-called nicotinic acid. The human body can convert both forms of vitamin B3.

At my age (I’m 67), maintaining good heart health is a top priority. I’ve been taking Make My Heart Beet for about a month now, and I must say, I feel more supported in my daily well-being. It’s comforting to know I’m doing something small yet meaningful every day for my heart. I’ll continue with this routine, and I’m glad to have found a vegan supplement that fits seamlessly into my life.

My experience
The Snack Smart bears really help curb my afternoon cravings – I feel more in control without needing extra snacks. And the Ah-mazing Hair gummies? My hair feels stronger, shinier, and just healthier overall.

My hair's new daily treat

Great taste – and it really helps with cravings!
I’ve been taking the Snack Smart Appetite Control gummies for a few weeks now and I’m honestly impressed! The apple flavour is super tasty, and I love that they’re vegan free.
I take 2 bears a day, as suggested, and I’ve noticed that my cravings between meals have definitely decreased. I feel more in control, especially in the afternoon when I used to snack the most.

The bloat is gone!
I've been using these for just over a month now and will rave about them to anyone! I usually suffer with awful bloating and cramps and after 2 weeks of using these little bears that has practically gone! I finally like how I look and feel again and don't have to worry about going out for food with friends! They are also really tasty!

Amazing results
I’ve been using these gummies for a few weeks now, and I am absolutely thrilled with the results! From the very first few days, I noticed a significant boost in my energy levels without the jitters or crashes I usually get from other metabolism-boosting supplements

Perfect!
After 2 weeks I started to feel positive changes. They are tasty and I am enjoying them.

I have a very fair complexion and have observed a slight improvement in my skin tone since using these products. While the change is not substantial, it is sufficient for me to feel pleased and self-assured without the need for artificial tanning. Additionally, they have a pleasant taste.
