Das tägliche Risiko von Vitamin B3-Dosis schneidet das Hautkrebsrisiko um bis zu 54%: Eine häufige, rezeptfreie Form von Vitamin B3 hat sich als kostengünstiger Verbündeter bei der Schutz des Hautkrebses entstanden, das das Risiko um durchschnittlich 14% erhöht und für alle, die zuvor eine positive Diagnose haben, auf massive 54% erhöht wurden.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:
**Daily vitamin B3 dose cuts skin cancer risk by up to 54%**
**A common, over-the-counter form of vitamin B3 has emerged as an inexpensive ally in protecting us from skin cancer, lowering the risk by an average of 14% and increasing to a massive 54% for anyone who has previously had a positive diagnosis**. This latest study of more than 33,000 patients supports earlier evidence that emerged in a 2015 Australian trial.
Researchers from Vanderbilt University Medical Center conducted a large real-world analysis of US veterans, which looked at the health records of 33,822 individuals, comparing those prescribed niacinamide (typically 500 mg twice daily for more than 30 days) with matched patients who didn’t take it.
Overall, niacinamide – also known as nicotinamide, a vitamin B3 form found in food and supplements that supports cellular energy, DNA repair and healthy skin – was associated with a 14% lower risk of developing skin cancer. When people began nicotinamide after having earlier received a positive skin cancer diagnosis, the reduction in risk was 54%. What’s more, the effect was seen in both basal cell carcinoma and cutaneous squamous cell carcinoma, with the largest drop in squamous cell cancers.
This is a great result but this is also the vitamin that often results in people overdosing on it when taken in pill form. Hopefully not too many people will think ‘more is better’ with this news.
Edit: my mistake, I was misremembering it with b6. You can overdose on it but it’s water soluble so less of a risk buildup wise. I did find an article from two years ago finding a potential link to heart attacks etc from 2 yrs ago on reddit, thought to be from more fast food, but that’s a coincidence, not what I was remembering.
My dad has Gorlin syndrome. Approximately 10years ago he commenced treatment with larger doses of B3. Instead of having 20-30 BCCs removed every ~6 months, the number has reduced to 8-12 removed every 12months.
When growing up it always confused me why he wore his hat in buildings with skylights etc. – he has always been extremely careful.
B3 has been a game changer for him.
There’s just no way to effectively test this and prove its causation. Too many variables.
We call b3 niacin. The FDA ensures it is added to all bread in America. Why would this article mention it can be purchased over the counter but fail to tell you it’s added to all bread products?
Taking it orally as well as using it topically have a lot of benefits to the skin. It’s worth doing both if you’re high risk!
For people interested in skin cancer prevention, the heliocare supplement is also interesting. Not as much evidence for skin cancer prevention, but still has a lot of benefit in mitigating uv damage.
But like, wear sunscreen religiously if you’re high risk, too – makes a huge difference. The biggest difference, really.
