We all know just how important eating our vitamins are. Vitamins are essential nutrients that nourish our body and keep vital organs functioning smoothly. While some help with immunity, others regulate the skin and hair.

And turns out a few of them can even keep you safe from cancer. In fact, a recent study found that increasing the consumption of vitamin B3 can protect the skin from the ill-effects of UV rays, potentially reducing the incidence of non-melanoma skin cancers.

Researchers in Italy isolated cells (human primary keratinocytes) from the skin of patients with non-melanoma skin cancers. These cells were treated with three different concentrations of nicotinamide (NAM), a form of vitamin B3, for 18, 24, and 48 hours and then exposed to UVB rays.

Vitamin B3 can work wonders when it comes to protecting the skin

Results show that pre-treatment with 25mM of NAM 24 hours before UV irradiation protected the skin cells from the effects of UV-induced oxidative stress, including DNA damage. Furthermore, it decreased antioxidant expression and blocked local inflammation by showing decreased nitric oxide release and reactive oxygen species (ROS) production and reduced iNOS protein expression.

Also watch:

Lara Camillo, a research student from the dermatological unit of AOU universitaria Maggiore della Carita, Novara, Italy says: “Our study indicates that increasing the consumption of vitamin B3, which is readily available in the daily diet, will protect the skin from some of the effects of UV exposure, potentially reducing the incidence of non-melanoma skin cancers. However, the protective effect of vitamin B3 is short-acting, so it should be consumed no later than 24 to 48 hours before sun exposure.”
