What Role Does Niacin Play In Hair Growth?

Niacin Hair Growth: Magic or Myth?


We all want long, strong, sleek and shiny hair, right? You know, hair is so integral to our own identity that when it doesnt look its best, feels lank or appears limp, starts to thin or even begins to fall out, it can really knock our self confidence. 

You may have tried every lotion and potion out there that promises to breathe life into your tresses, and yet your hair still doesnt want to play ball!  However, there may be an avenue you havent explored yet…

One vitamin that’s thought to play a key part in hair growth and health is Niacin. You may not know much about Niacin and its contribution to hair growth, but perhaps you’re better acquainted with its other name: Vitamin B3.

So, how does Niacin for hair growth work? Where do we find this ‘miracle’ vitamin Niacin in our day-to-day life? And, how do we incorporate Niacin into our daily routine to reap these potential hair growth and health benefits…?

Niacin & Hair Growth; The Science

Niacin – also known as Vitamin B3 – is a water soluble vitamin that is utilized by the body for many of its functions; apparent inside and out!

So, heres the science-y part: Niacin is necessary for our bodies to help convert the food we eat into energy. It helps the body to utilize protein and fat efficiently and promotes a healthy nervous system.

But, that’s not all! For hair growth, Niacin is considered to be a huge contributing factor due to the way it helps blood circulation. Niacin helps the blood deliver oxygen and nutrients directly and efficiently to your hair follicles, which in turn helps fuel a healthy scalp.

That’s right! Poor blood circulation can contribute to hair thinning and loss.

Having a healthy and appropriately nourished scalp helps your hair have the best chance of growing thick and luscious… And, getting your recommended daily allowance (RDA)* of Niacin can help promote that all important perfect environment for healthy hair growth!

*The RDA of Niacin is 16 mg for males and 14g for females (18mg if pregnant, 17mg if breastfeeding).

How To Use Niacin For Hair Growth

The easiest way to ensure you’re getting your daily dose of Niacin is to take a Niacin supplement, to help your on your way toward long & strong hair growth!

Why not give Cel’s Advanced Hair Supplement a try? Our supplement contains a unique blend of hair-strengthening ingredients, including Niacin and Super-Biotin, and is formulated to support a healthy scalp, and improve the appearane of your hair!

Just two capsules a day of our scientifically optimized Advanced Hair Supplement can help begin the transformation of thin, dry hair that’s lacking volume and shine into a glossy, long, voluptuously strong mane.

Remember, its always a good idea to chat to your doctor before beginning any new supplements or diets.

Niacin deficiency in the western world is extremely rare, but if you spot the signs that you’re possibly lacking in the vitamin (fatigue, headaches, skin problems, diarrhea, memory loss, thinning hair, rapid weight gain etc.) it may be that your body is having trouble absorbing Niacin.

If you smoke, drink heavily, take painkillers regularly, or are on some routine medication, this can make it harder for your body to collect and distribute the Niacin it needs, so check in with your doctor if you have any suspicions.

A varied, healthy diet that includes Niacin rich foods can really help your body stay on top of it’s Niacin levels and thus help and enable healthy hair growth!

Eating Your Niacin: Foods Rich In B3

Niacin can pretty much be found in nearly all the foods we eat! Yay! This actually makes it pretty easy to get all the Niacin you need in your day to day diet (which is why Niacin deficiency is very rare)!

Add a few of the following foods to your daily meals, and youll be well on your way to absorbing your daily recommended intake of Vitamin B3…

  • Brown Rice
  • Avocados
  • Lentils
  • Beef
  • Smoked Salmon
  • Pea

  • Sweet Potatoes
