One of my patient’s inquired “if Niacin (B3) helps with hair health?” Well, yes and maybe no….Niacin is one of several “scientifically documented nutrients” that contribute to overall hair health, but it doesn’t end there! First, one MUST have proper circulation to the hair follicles in our scalp…then nutrients can feed these hair cells to do their job–grow hair. Hair is 88-90% protein- best gotten from fatty fish (salmon, sardines), grain-fed beef. eggs, beans. etc.. Next, Vit D, Zinc, Copper, Inositol, Biotin (Vit H: part of the B-complex family), Pantothenic Acid (B5), Niacin(B3) have all demonstrated some influence with hair texture, growth, graying, etc. So, if you go to a pharmacy, health food store or “on-line” you will find numerous products that I refer to as “designer supplements” (products developed based on the most up to date “guaranteed new discovery” for health). Buyer Beware- food is the basis of “nourishing” your body (hair cells -all cells). When I was 23, my first introduction to “Food Supplmentation” was Nutritional Yeast for healthy hair. I have been taking it regularly for the past 40+yrs. Initially, I did not know why this person told me to do it until the late 70’s when it was reported in the Journal of Clinical Nutrition that “hair health was found to be related to a Copper deficiency”. I looked at my can of Brewer’s Yeast and I was surprised to see that Copper, as well as many other hair related nutrients, were part of that food source. It was very high in protein, Biotin, Inositol, Niacin, B5, Zinc, etc….that’s when I realized that Food should be my supplementation form not the “miracle cure of the moment”.
