NIACINAMIDE
Keeping with tradition,
If there’s so much I must be, can I still just be me? The way I am?
I’d like to think Niacinamide knows this Lion King line, it doesn’t have an identity issue. It just has a lot to offer.
The Basics
Niacinamide (aka nicotinamide if you want that high) is vitamin B3’s alter ego. You’ll find it in meat, fish, legumes, and milk. And yes, it’s the same thing companies have placed at the skincare helm. Adding it to skincare serums and swearing it’ll erase all your problems.
Well, some of it is true; Niacinamide does wonders for pigmentation and acne, but some other things are just hype. The arbiters of this truth? Scientists, literature, journals.
THE ORIGIN STORY
Back in the day, if you didn’t get enough vitamin B3 or Tryptophan, an amino acid, your body freaked out and fell into Pellagra. 3 D’s, stay with me now: dermatitis, diarrhea, dementia. Basically, your body channeling its inner Shawn, “Treat me better!!”
Corn-heavy diets were the main culprit. At first, everyone thought Pellagra was another infectious disease. But Joseph Goldberger did some investigations and said, “Put down the antibiotics, it’s a diet problem”. He even spotted a “Pellagra-Preventive” factor in meat and milk. Then came Sir Conrad Arnold Elvehjem in 1937, who put some science shine on it, and boom nicotinic acid and nicotinamide became a thing. He isolated Niacin (from meat), and its two main forms: nicotinic acid and nicotinamide.
Structure Activity Relationship
Niacinamide is basically a pyridine ring with an attached carboxamide group at position three. This little combo is the backbone and scaffold of NAD⁺ and NADP⁺- major players in metabolism.
The gist?
Niacinamide gets converted to NAD⁺ and NADP⁺. These are coenzymes, aka organic cofactors, aka the unsung helpers. Think of enzymes as Santa, and co-factors as the elves, the little helpers that make the toy. So no elves, no gifts for saint Nick to deliver.

(Basically, cofactors are non-proteinaceous compounds that help enzymes do their work; and coenzymes are cofactors that contain carbon. Hence, organic cofactors)
- NAD⁺ → NADH fuels catabolism (science for breaking large molecules down and making ATP).
- NADP⁺ → NADPH fuels anabolism (building shiny new molecules).
The pyridine ring is why the redox reactions (above) happen. And the carboxamide group? It keeps niacinamide from causing the infamous flushing you get with plain niacin.
From Steak to Cells
So how do we get from meatloaf to molecule magic?
Easy: when you eat meat, fish, milk, or legumes, you’re actually getting niacin as nicotinic acid or nicotinamide. Your gut absorbs it, it hops into circulation, slides into cells, and transforms into NAD⁺/NADP⁺.
Alternative pathway: Tryptophan can also morph into niacinamide via the kynurenine pathway. Point is, your body’s has options.
However, both nicotinic acid and nicotinamide are highly bioavailable, meaning alot of it reaches your circulation, hence your body can use them efficiently.
Beyond the Skincare Aisle
Yeah, niacinamide is having its time in the derma sun. But don’t box it in. Its more than a pretty face maker:
- Energy metabolism (Involved in making ATP, the body’s energy currency).
- DNA repair & genomic stability (no niacin, no stable genome, big deal).
- Cell signaling & aging (basically whispering secrets from cell to cell and influencing how gracefully they age).
Final Note
So yes, slap it on your face if you want glowing skin- I do. But remember: niacinamide is more than derma hype, its a major stakeholder of your metabolism. NAD⁺ and NADP⁺ are the real workhorses.
Hopefully, like Kiara learned more about herself, you know Niacinamide more.
